Astronomers Triple Universe's Star Count

'Billions of Earths' may orbit vast number of newly spotted stars

(Newser) - The known universe just got a lot more crowded. Astronomers studying distant, elliptical galaxies say they spotted many more red dwarf stars than anticipated, suggesting that the number of stars in the universe is triple earlier estimates, the Daily Mail reports. The researchers now believe there are three septillion stars...

NASA Finds Singing Stars

Telescope spots sound waves traveling through space

(Newser) - NASA has discovered a group of massive red stars that are actually humming to themselves. The planet-hunting Kepler space telescope recently spotted sound waves emanating from the stars, the Wall Street Journal reports. NASA recorded the tune, and played it recently at a press conference in Denmark. “It is...

'Cannibal Star' Eats Neighbor

Hungry BP Piscium caught in the act

(Newser) - A "cannibal" star in the Pisces constellation appears to have gobbled up its neighbor and belched out a disc of dusty matter. X-Ray images revealed the remains of either a young star or a large planet inside BP Piscium, which has recently entered the expanding "red giant" phase...

'Citizen Scientists' Find Rare Star

Spare computing power donated to sift through observatory data

(Newser) - Three regular people who volunteered to put their idle home computers to work crunching scientific data in off-hours have been credited with making a major discovery in deep space. The "citizen scientists"—two in Iowa and one in Germany—downloaded and processed the data that found a disrupted...

Astronomers Discover Impossibly Huge Star

It's at least 265 times more massive than the sun

(Newser) - Astronomers have discovered a star so big and bright that it stretches the boundaries of what scientists believed was possible. The star, known so far only as R136a1, has an observed mass 265 times greater than our sun, and modeling suggests it was once 320 times bigger. “If it...

Scientists Creating Star to Solve Energy Woes

Giant laser will zap mini-sun into existence

(Newser) - Scientists are planning to use the world's largest laser to zap a tiny star into existence on Earth. The project at California's Lawrence Livermore National Laboratory aims to create nuclear fusion by firing the giant laser at hydrogen isotopes. This would, theoretically, cause a miniature sun capable of filling all...

NASA Releases Explosive Sun Shots

Historic images reveal high-def surface, flares

(Newser) - NASA has released astounding new photos and videos of the sun for the first time revealing high definition, close-up views of the solar surface and exploding flares. The images were captured by the space telescope of the Solar Dynamics Observatory, and are providing historic new insight into sun mechanics, notes...

Nearby Star Could Doom Earth, Scientists Warn

... in 10 million years

(Newser) - The T Pyxidis binary star system is a lot closer than earlier believed, and that could be very bad news for Earthlings, according to a team of astronomers. One of its stars is a white dwarf set to become a Type 1A supernova—10 million times stronger than a regular...

Farthest-Ever Star Blast From Ancient Cosmos

Gamma ray burst took 13 billion years to reach Earth

(Newser) - Astronomers have detected a cosmic object more distant than any ever seen: a gamma ray burst about 13 billion light-years from Earth. The massive, luminous burst occurred about 600 million years after the Big Bang—that is, when the universe was 4% of its current age—and only lasted for...

New Planet Expected to Crash and Burn

It defies laws of physics

(Newser) - Scientists in the UK have discovered a planet that defies the laws of physics, the Independent reports. WASP-18b, which is orbiting a star 1,000 light years from Earth, is so big and close to the sun that it should be pulled toward it. "The spin of the star...

Monster Black Hole Sucking Up Space

(Newser) - A monstrous black hole near the center of a distant galaxy is sucking up stars, gas and dust, and spitting out baby stars, NASA scientists have discovered. The black hole is 100 million times the mass of the sun, reports the Telegraph. It lies at the center of a galaxy...

Scientists Spot End of World

Remains of solar systems discovered around dead stars

(Newser) - Astronomers looking at dead stars trillions of miles away believe they have glimpsed Earth's eventual fate, the Times of London reports. The scientists found that many white dwarfs—stars that swelled, burned out, and collapsed—are surrounded by a dust they think is the remnants of planets like ours destroyed...

Nearby Solar System Looks Familiar

(Newser) - A nearby solar system looks a lot like ours, complete with newly identified asteroid belts, gas giants, and a similarly sized sun, Space.com reports. The star at the center of the system is visible without magnification, and scientists say they can infer the presence of planets in a zone...

Light Pollution Veils Starry Skies

Obscured night sky could be a health hazard

(Newser) - Dark skies are being engulfed by light all over the world, creating some unexpected consequences, the Wall Street Journal reports. Over two-thirds of the world's people— including nearly all Americans—can no longer see "what is possibly the most extraordinary natural wonder," said one astronomer. The amount of...

CNBC Focuses on Fresh Face of Biz News

Erin Burnett's network tests new formula for creating a star

(Newser) - Since Jim Cramer and Maria Bartiromo became breakout stars for CNBC, the network has been trying to cultivate more of the sort of talent that draws a devoted viewership. Erin Burnett, 32, has enjoyed one of those carefully crafted career trajectories, moving from writer to co-anchor in just weeks. The...

Stargazers Witness Birth of Supernova

Astronomers first ever to see star's explosive death throes

(Newser) - A  pair of Princeton astronomers have become the first people ever to witness the explosive death of a star, Space.com reports. The pair were observing another supernova in its later stages when they happened to spot a huge burst of X-rays 90 million light years away. Astronomers believe their...

Youngest Supernova Discovered

Exploding star found in Milky Way

(Newser) - Scientists have discovered the remains of the youngest exploding star, or supernova, ever seen in the Milky Way, shedding new light on the life cycles of stars. The baby supernova G1.9+0.3 is a mere 140 years old, reports National Geographic. Supernovas are a vital component of galaxy development...

Black Mini Still Has Hole Lotta Power

15-mile-wide black hole is smallest ever found

(Newser) - Astronomers have spotted the smallest black hole ever discovered, Reuters reports. It is just 15 miles across—the size of a city—but still has a pull strong enough to "stretch your body into a strand of spaghetti," said a NASA researcher. The relative pipsqueak weighs about as...

Exploding Star Brightest Object Ever Seen

Brightest object ever observed by humans

(Newser) - Light from a star that exploded billions of years before the Earth was formed have been spotted by terrestrial astronomers, Space.com reports.
