NASA/JPL-Caltech/UCLA Researchers at the University of Bonn in Germany and the Russian Academy of Sciences have spotted an incredibly unusual and rare star in the middle of a cloud of gas around 10,000 light years from Earth.The star, dubbed J005311, appears to have risen from its cosmic grave after two dead stars collided with one another in the constellation Cassiopeia. The findings, published in Nature on May 21, reveal the nature of the exotic zombie star and its unusual properties. The team discovered the bizarre object using data from NASA’s Wide-field Infrared Survey Explorer (WISE) space telescope and subsequently observed it using a ground-based telescope at Russia’s Special Astrophysical Observatory.At the end of a small star’s lifetime, when all of its fuel has been exhausted, it turns into a “white dwarf” — a tiny, dense, dead star. For the most part, a white dwarf is done for after that. However, researchers at Bonn examined the radiation emitted by the strange star and found that it was lacking in both hydrogen and helium, usually present in a white dwarf.bangThe infrared nebula of J005311. Vasilii Gvaramadse/Moscow University Due to J005311’s unusual emission signal, the researchers suspect what they’ve detected is the result of a cosmic fusion between two white dwarfs that circled one another for billions of years.”Such an event is extremely rare,” explains Gotz Gräfener, co-author on the study, in a press release. “There are probably not even half a dozen such objects in the Milky Way, and we have discovered one of them.”Generally, collisions of white dwarfs end up in huge stellar explosions, known as supernovae. But J005311 didn’t explode. Instead, it was reanimated and started burning again.It shines about 40,000 times brighter than our sun, has a strong magnetic field and its stream of stellar winds are moving at 16,000 kilometers per second (approx. 9950 miles per second). At approximately 360,000 degrees Fahrenheit (200,000 degrees Celsius), it’s also incredibly hot. What fate awaits the new star? Death, naturally. The exceptional event has only delayed its demise by a few thousand years. Its second run at life will be over once it has, again, exhausted all its fuel. At that point it will collapse into a tiny star and explode.last_img read more

first_imgPixabayA new study conducted by Total Jobs has revealed that one in five office mugs contain fecal matter which may not be yours. Usually, fecal matters get dumped in office mugs as more than 25 percent of employees in an office often fail to wash hands properly after coming out of the loo.In a recent post published by Total Jobs, hygiene doctor Lisa Ackerley also advised various tips to prevent an infection which may be caused due to contaminated office mugs.Lisa Ackerley revealed that simple rinsing will not eliminate germs completely from the mug, instead, people should use a dishwasher if it is available in the office. Ackerley also urged people to bring their own mug and bottle to the workspace, and do not share them with others.”Wash up your dedicated work mug in the evening. Wash bottles at least once a day because water is not sterile, and bacteria will build up over time. Don’t let anyone else use them,” wrote Lisa Ackerley.The study report also revealed that the average office desk might be loaded with 400 times more bacteria than a toilet seat. Lisa also cited the example of a recent US study which hinted that phones in the office desk are very much contaminated. This study led by Dr Charles P Gerba from the University of Arizona found over 25,000 organisms per surface on the office phone.As per Lisa Ackerly, the best way to avoid an infection from the office seat is by using the same desk every day, without sharing it to others. The hygiene doctor also urged people to use antibacterial wipes and handwashes while using desks, phones and pens used by others.”Pen-chewers – try to break the habit. If you don’t know where a pen has been, you could be ingesting bacteria or viruses left by someone else. It could have been in someone else’s mouth, gathering dust under the desk or dropped on the loo floor. Give borrowed pens a clean with an anti-bacterial wipe,” added Lisa.last_img read more
