Astronomer tells Wikinews about discovery of closest black hole known so far

Friday, May 22, 2020

A study published in journal Astronomy & Astrophysics last month reported astronomers from the European Southern Observatory (ESO) and elsewhere discovered a black hole in the Telescopium constellation. The study stated the black hole is about 1010 ± 195 light years (310 ± 60 parsec) away from the Solar System, meaning it is the nearest known black hole from the Earth. The nearest previously known black hole — V616 Mon — the study noted was usually estimated at more than 3000 light years away.

The black hole described in the study is located in the HR 6819 stellar system of Telescopium constellation, making it the first system visible to the naked eye to contain a black hole. HR 6819 contains two stars, and they are visible from the Southern Hemisphere. The astronomers started observing the system in 1999. Initially, they thought it was just a binary system, consisting of two stars. However, upon examination, the researchers concluded there was a third unseen object in the system. One of the two stars in the HR 6819 system is close to the black hole and orbits the black hole in just 40.333 ± 0.004 days.

This newly discovered black hole does not have an accretion disk. A black hole forms an accretion disk when a significant amount of matter orbits the black hole, as depicted in the image. Accretion disks often emit electromagnetic radiation. Since this black hole does not have an accretion disk, researchers had to rely on the gravitational effect of the black hole on the nearby star in order to discover it.

Researchers used the binary mass function to conclude the black hole had a mass of at least 4.2 M? (Solar masses; 1 Solar mass = mass of the Sun). Its companion star, which orbits the black hole in about 40 days, is classified as a B3 III star. The outer star is classified as a Be star. Be stars rotate very quickly around their axes. Since the outer star rotates so rapidly, the star is not exactly spherical, but instead oblate, bulged at its equator, forming a gas disk around the equator.

The research suggested HR 6819 was very similar to another system LB-1. The HR 6819 system is estimated to be between 15–75 million years old (myr). The inner star has estimated mass of at least 6.3 ± 0.7 M?. Using the mass and the speed at which the inner star rotates, the researchers concluded the black hole had an estimated mass of 5.0 ± 0.4 M?. Researcher and co-author of the study Thomas Rivinius told Wikinews the inner star and the black hole are closer than the Sun and the Earth (1au; 150 million km; 93 million miles).

The researchers dedicated the paper to Stanislav Štefl, one of the fellow researchers who died in a car accident in 2014 in Santiago, Chile.

Wikinews caught up with Thomas Rivinius to discuss about this discovery.

Collyer brothers to bid for Everton F.C.?

Tuesday, April 4, 2006

Rumours in London and Merseyside have linked Paul and Oliver Collyer, creators of the football management series Championship Manager, with a possible bid for Premiership football team Everton.

The Goodison Park club, under the chairmanship of former Coronation Street actor Bill Kenwright, were subjects of a failed takeover bid in August 2004. After suffering the blow of failing to get beyond the qualifying stage of the Champions League, Kenwright is known to have recently sought additional investments in the club.

While a move is not thought to be imminent, the recent takeover of the brothers’ games development company Sports Interactive by game giant SEGA could well prove the catalyst for action by the lifelong Evertonians. The company’s PR guru Miles Jacobson was forced into an official denial of the story soon after the takeover news broke on Tuesday morning. The Collyers themselves have as yet been unavailable for comment.

Let An Expert Plumber Improve The Home Or Eliminate Plumbing Failures

byadmin

For most home and property owners, the primary areas of concern regarding possible failures are those things that can damage the structure. Consider the case of a leaking pipe. These problems can occur in the most unusual places, and this often makes it difficult to eliminate the problem or repair any resultant damage. The first step is to hire an experienced Plumber to locate and diagnose the issue. Leaks may not always be due to simple problems. For instance, a crack in the pipe can come from excessive pressure changes, weak materials, abrasion from mounting supports or rubbing on a wall and this is just a few of the possibilities.

There are a surprising number of locations where a leak might exist that cannot be seen by the naked eye. Hidden leaks are a major concern because they often occur long before the homeowner notices the problem. In some cases, the issue may not be apparent until the utility bill gets out of control. Locating the leak requires an expert with some special tools. Specifically, they require acoustic sampling systems capable of listening inside the walls and may need GPR (ground penetrating radar) to discover voids in the soil caused by excessive amounts of water.

Eliminating these failures is usually more involved than simple pipe repairs because there is some demolition required. One example of a difficult repair is a broken pipe on a concrete foundation. This issue may occur more often than people realize because some home designs use this method for protecting the pipe. The major issue in making a repair of this nature is cutting through the concrete. Improper cutting could break more pipe or worse, damage the foundation itself.

For some folks, the most important reason to contact a Plumber is the need for home improvement. There are several areas where an expert can provide help, and these include the laundry area, kitchen and baths. A properly constructed kitchen or bath can improve the value of the property, but a more important use is making the space viable for the occupants. This is often necessary once the homeowners realize the space they live in doesn’t fit their needs. The kitchen is a prime example since most family members congregate there around mealtime.

NASA calls end to Mars Phoenix mission

Tuesday, November 11, 2008

NASA officials have decided to call an end to the Mars Phoenix Mission, after winter took hold of the red planet. NASA calls the mission a total success.

“Phoenix has given us some surprises, and I’m confident we will be pulling more gems from this trove of data for years to come,” said Phoenix Principal Investigator Peter Smith of the University of Arizona in Tucson, Arizona in a statement on NASA’s website.

The Phoenix lander last sent a signal to Earth on November 2. NASA says that colder temperatures, lack of sunlight and increased dust particles on the lander’s solar arrays has stopped its on board batteries from charging, causing the instruments to fail.

Despite the news, Phoenix had operated two months longer than scheduled. The lander had been operating for over five months.

Phoenix was responsible for several discoveries on Mars, including the confirmation of the presence of water-ice, which had previously only been detected from space.

“Phoenix provided an important step to spur the hope that we can show Mars was once habitable and possibly supported life. Phoenix was supported by orbiting NASA spacecraft providing communications relay while producing their own fascinating science. With the upcoming launch of the Mars Science Laboratory, the Mars Program never sleeps,” said Doug McCuistion, director of the Mars Exploration Program.

NASA officials will continue to listen for a signal from Phoenix, in hopes that it will phone home again in the near future.

Original Story
  • “Hotel development proposal could displace Buffalo, NY business owners” — Wikinews, February 17, 2006

Friday, March 10, 2006

Buffalo, New York —The Common Council of Buffalo voted on Tuesday to send the Elmwood Village Hotel proposal “to committee for further discussion”, after citing the need for more public involvement.

The Elmwood Village Hotel is a development proposal by the Savarino Construction Services Corporation, a project designed by the architect Karl Frizlen of The Frizlen Group. The hotel would be placed on the southeast corner of Elmwood and Forest Avenues in Buffalo.

To make way for the project, at least five buildings located at 1109 to 1121 Elmwood Ave would be demolished. At least two properties on Forest Avenue could also be demolished. The Elmwood properties, according to Eva Hassett, Vice President of Savarion Construction, are “under contract”, but it is unclear if Savarino Construction actually owns the Elmwood properties. Hans Mobius, a former mayorial candidate, is still believed to be the current owner the properties. Mobius also owns 607 Forest Avenue.

The properties 605 and 607 Forest Avenue could also be included in the proposal according to Hassett.

“We would use a Special Development Plan to rezone 1119-1121 Elmwood and 605 Forest to a C-2 zoning category,” stated Hassett. It is possible that Savarino Construction may try to obtain a variance for 605 Forest, which would allow them to enforce eminent domain, should the hotel be allowed to go forward.

The building at 607 Forest was also discussed to be rezoned, but it is unclear what the plans would be for that property. During the February 28 Common Council meeting, Hassett stated that the properties 605 and 607 were “now off the agenda”.

Pano Georgiadis, owner of Pano’s Restaurant at 1081 Elmwood, owns the property at 605 Forest and attended Tuesday’s Common Council meeting.

“Having a hotel is a bright idea. We all love the idea of a hotel, but the way that it is presented, is wishful thinking. This hotel does not fit. It’s like putting two gallons of water in a gallon jug, it does not fit. At the last meeting, the architect admitted that they are planning to put the undergound parking lot and the hotel, right at the property line. If I open my window, I will be able to touch the wall, that goes fifty feet high”, said Georgiadis.

“There is a problem having a seventy-two room hotel and fifty-five parking spaces. That means that all the other cars will spill all over the neighborhood. The footprint is simply too small. If you have a bigger [parking] lot, and a smaller hotel, I will welcome a hotel. I have a parking lot at my own business, and I am chasing people all day long. Remember, the city says it has ‘zero tolerance [for illegal parking]’. Try telling that to the guy from Albany who came to see his kids, that are going to Buffalo State, who would get tickets totaling over a hundred dollars”, added Georgiadis.

The city’s Planning Board is scheduled to meet on March 14, 2006 at 9:00 a.m. about the proposal. Although a discussion will take place, no vote is expected to be taken.

At the moment, none of the properties are zoned for a hotel. Savarino Construction plans on asking for a C2 zoning permit. If that does not work, they plan to implement a new zoning plan called a “special development plan” which would allow for only a hotel on the site. That zone would not be able to be changed.

“This [project] justifies Mobius’s refusal to invest in any maitenance[sic] or improvements”, on the properties said Clarence Carnahan, a local resident. “Where were the Council persons over the years? Where were the city inspectors over the years, to make sure that he maintained and improved his properties? The government was supposed to be protecting, not being preditorial. I see a predatorial issue here when it comes to this hotel. Over the years: Why has the local government been disfunctional when it came to Mobius’s properties? Refusal to invest in improvements, doesn’t that sound like a slumlord? Maybe I am missing a point here, but what kind of messages does this send to other slumlords that havn’t[sic] been jailed or fined? It’s [the hotel] trying to be pushed through.”

Carnahan also presented signs for residents and or business owners who are opposed to the hotel, that could be placed in windows or on stakes in the yard. Some of the signs said, ‘No tell hotel’, ‘Hans off, no hotel’, ‘It takes more than a hotel to make a village’. and ‘Keep Elmwood free, no hotel’. Carnahan plans on making more signs for a protest to be held on Saturday March 18, at 2:00 p.m. (EST) on Elmwood and Forest. Some signs were given to individuals after the meeting.

“First things first, Hans is the problem, and I don’t think it has been addressed. Let’s roll back the clock on this project. What can we do with Hans? There is such thing as eminent domain, which could be of greater interest to the community, to seize the property at its lowest assessed value”, said Nancy Pollina, co-owner of Don Apparel with Patty Morris at 1119 Elmwood. “There are so many ideas that have not been explored and we are about to give this parcel away, to a big developer.”

Mobius has not returned any calls by Wikinews regarding the situation.

A freelance journalist writing for Wikinews has obtained a letter, exclusively, addressed to one of the five business owners from Hans Mobius stating:

There is a proposal to develop my property which you are currently renting. Because of opposition to this development, it does not look like it will happen. I will let you know if there any changes.

Despite the letter, there have been no plans or decisions made to end the proposal.

To date, none of the business owners or residents of 1119-1121 Elmwood have received an eviction notice.

Business owners and residents gave an indication of what they would like to see happen at the corner; a project similar to one done locally last year. There, developers renovated two buildings on Auburn and Elmwood Avenues, merging the buildings into one thus allowing for more shop space. Among some of the shops to move in after the development were Cone Five Pottery, The Ruby Slipper, and Abraham’s Jewelers. Prior to the renovation work, the left building in the picture was boarded up for several years. Many of the concerned locals would like to see a similar development on Forest and Elmwood.

Rocco Termini, a developer in Buffalo, proposed a similar design at the February 28 community meeting

In an interview after the February 28 meeting, Termini stated, “I will be willing to take a look at this myself, or I would be more than happy to be partners with Sam, Sam Savarino”, who is President and Chief Executive Officer of Savarino Construction Services Corp.

So far Savarino Construction has no plans to team up with Termini.

How To Get Effective One To One Business Coaching}

Submitted by: Helen Saunders

Everyone who owns or manages a business knows how difficult some of the in-house tasks are. It is extremely tough to keep employees motivated, without making them feel like they are doing extra work. In turn, it is hard to get employees to do any work if they are not motivated. Sure, businesses can get rid of employees who do not appear to be motivated, but they will likely find more of the same in the next candidates they hire. Businesses have to realise that the employees may want to feel motivated, but if they feel the environment does not reward this behaviour it will discourage them. Thankfully, business coaching courses can solve these problems. Not only will one to one business coaching solve internal matters, they will also assist with external operations. Businesses often find that they are spending a lot of time trying to market their company, but seemingly do not get results. The coach will be able to examine their marketing plan to ensure they are going after the proper clientele. A lot of business coaching training courses reveal to businesses that they have a proper strategy for marketing their company, but they are simply going after the wrong businesses or customers.

How the Courses Work

YouTube Preview Image

The courses can range from a single session to a continuous programme. Businesses, who feel they have been successful over the years, but are now in a slump, may just need a single session to get them back on track. The business coaching courses may quickly spot a small issue, such as employees realizing the bonuses or benefits have been reduced over the years. For businesses that are having bigger issues, such as a substantial decrease in sales, may need to have continuous assistance. This type of scenario will obviously take a longer time to get the business going back in the right direction. The coaches will guarantee that any business can make huge improvements from the coaching services, as there is always room for improvement. Even the best leaders can implement new leadership techniques to make the business run a lot smoother. In fact, most successful businesses have their leaders regularly take business coaching courses.

Benefits

Businesses will obviously want to know what other benefits these programs can offer before paying any money. These programs will substantially increase employee satisfaction, as people want to work for a successful company. Leaders will also receive training on how to keep employees feeling positive and confident about themselves. The coaches have various techniques that can are used to make people feel good about themselves, which will make the employees actually want to come to work. If a company can have employees that are excited to be at work, the performance and profits of the business will substantially increase. The program also allows company leaders, as well as employees, to find the ideal work-life balance. Too many people begin to hate their jobs simply because they feel that their job creates too much stress. They allow this stress to build-up, to where they even think about work issues during their time off. These business coaching training courses will teach them how to leave their issues at the door, so they can enjoy their time off. The coaches will also inform the leaders to refrain from making their employees feel guilty for separating their work and personal lives.

One to one business coaching will drive results in any business, as every leader has room for improvement. The business will see employees who love their job, which will show to customers. Customers like doing business with companies who have employees that seem happy to be at their job.

U.S. Rep. Tom Tancredo clarifies ‘nuke Mecca’ comments

Friday, July 22, 2005

Representative Tom Tancredo (R-CO) has clarified his earlier statement that “you could take out their holy sites,” in the event of a nuclear attack upon the U.S. by Islamic terrorists. Rep. Tancredo has refused to make any apologies, saying “When we bombed Hiroshima, when we bombed Dresden, we punished a lot of people who were not necessarily (guilty). Not every German was a member of the Nazi Party. You do things in war that are ugly.” However, Tancredo emphasized that he was speaking hypothetically and not necessarily suggesting policy.

The remarks, made in a July 15th radio interview, hosted by Pat Campbell of WFLA in Orlando, Florida, have drawn support from conservatives groups such as Northeast Intelligence Network and Free Republic, and have offended the American Muslim community.In the interview, Tancredo discussed his request for information from the Justice Department regarding the claim of evangelical Christian journalist Joseph Farah that al-Qaida has smuggled multiple nuclear weapons into the U.S.

New book links Bonds, Giambi and Sheffield to BALCO

Thursday, March 23, 2006

The new book Game of Shadows: Barry Bonds, BALCO, and the Steroids Scandal that Rocked Professional Sports, by Mark Fainaru-Wada and Lance Williams of The San Francisco Chronicle, is being released today. The authors not only implicate professional baseball celebrity Barry Bonds in the use of performance-enhancing drugs, but also say Gary Sheffield received human growth hormone and testosterone from Greg Anderson, Bonds’s personal trainer.

The book goes on to claim that Jason Giambi also took performance-enhancing drugs from Anderson. Bonds continues to insist that he did not realize his trainer was giving him steriods. He claimed in his grand jury testimony that he thought he was receiving flaxseed oil and an arthritis salve. Sheffield’s response to the claims was quite simple: when asked if the allegations made against him were true, his response was “Nope.”

Despite the book’s accusations of Sheffield and Giambi, it centers around Bonds and the founder of the Bay Area Laboratory Co-Operative or BALCO, Victor Conte Jr. Conte is currently serving four months in prison for distribution of steriods and money laundering. It appears that the steroid controversy concerning Bonds will only intensify as he continues to march on towards the career home runs record, one of baseball’s most sacred records.

What Eight Kinds Of Food Can Affect Your Sleep Quality

What eight kinds of food can affect your sleep quality

by

First, caffeine

Caffeine is a xanthine alkaloid compound, is a central nervous system stimulant, can temporarily drive away the drowsiness and restore energy. So, caffeine can be refreshing. However, nutrition experts said, it is little-known that caffeine cannot provide energy to the body, it\’s just a kind of irritant, so before going to bed, eating too much caffeine will cause too much stimulus brain, find it difficult to fall asleep.

Second, cheese

Cheese is rich in protein and lipid, has high nutritional value. It contains rich salts and vitamins and other trace components are great benefit to human health.

In addition to disrupting sleep, processed or smoked meat is the most unhealthy junk food.

Fifth, drinks

Alcohol has a calming effect, but it is strange that it can make you more awake at night. Dr. Pasquale said, a lot of people drink to relax and recover from fatigue, in fact, alcohol would hinder the body into the REM (rapid eye movement) deep sleep stage. Precisely because of this, many people snore loudly in their\’s sleep after drinking and still feel groggy the next day. The fact is equivalent to reducing the quality of sleep.

Sixth, milk chocolate

Studies have shown that the nutritional content of the milk chocolate can promote the release of monosaccharides to improve blood circulation, which helps improve cognitive abilities, in other words, making the brain in a more sober state, Dr. Pasquale said, Usually, milk chocolate contains stimulant tyramine acid can be converted into tyrosine, which causes alertness and restlessness, and difficulty falling asleep.

Seventh, tomato sauce

Tomatoes contain vitamin C in the tomato, which can help digestion, detoxify, lower blood pressure and so on, especially for patients who are hypertension and kidney disease, it has adjuvant therapy.
