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...

Alien Planet Discovered in Milky Way

HIP 13044B and its star originated in different galaxy

(Newser) - As planets go, HIP 13044B is one hell of a survivor. Astronomers say the planet—the first one originating from another galaxy ever found in the Milky Way—is part of a solar system that once belonged to a dwarf galaxy that was cannibalized by our own. The planet has...

Milky Way Emits Huge Gamma Ray Bubbles

Massive bubbles of energy stump astrophysicists

(Newser) - Scientists say they have discovered two vast and mysterious bubbles of gamma-ray energy coming from the center of our galaxy. The bubbles, which extend an incredible 25,000 light years above and below the galaxy's plane, were discovered by scientists analyzing data from NASA's Fermi telescope, the Los Angeles Times...

Astronomers Spot Most Distant Galaxy

The stars are 13.1B light years

(Newser) - Astronomers in Chile have spotted the most distant galaxy in the universe—some 13.1 billion light years away. Its light has taken almost the whole life of the universe to get to us: The light photons detected by the astronomers started their journey when the universe was just 4%...

Universe's Fate: Cold, Dead Wasteland

Amount of dark energy suggests it will expand forever

(Newser) - Scientists say they've learned "exactly what the fate of the universe will be," and it doesn't sound pleasant. A team led by a NASA astronomer predicts the universe will continue to expand forever and eventually will become a cold, dead wasteland, the BBC reports. How did they arrive...

Space Telescope Captures Big Bang Radiation

Planck beams back microwave map of entire sky

(Newser) - The European Space Agency’s Planck space telescope has beamed back its first, much-anticipated image: a map of the entire sky, composed of microwave light. That bright line in the center of the image is our own Milky Way galaxy, and the lights surrounding it represent not stars but the...

Black Hole 'Hurled' From Galaxy

Object with the mass of a billion suns spotted moving at high speed

(Newser) - Astronomers believe they have spotted a supermassive black hole being flung out of its galaxy. Supermassive black holes—which have a mass roughly a billion times that of the sun—are usually found at the center of galaxies, but this one is traveling away from the core of its galaxy...

Telescope Spots 'Impossible' Star

Will become one of biggest and brightest in galaxy

(Newser) - The Herschel telescope has made an "impossible" discovery: a star so large it dwarfs our sun—and it's still growing. The newborn is already eight to 10 times the size of the sun, and will continue to feed off the 2,000 solar masses that surround it. While scientists...

32 New Exoplanets Discovered

New finds signal that cosmos harbors wealth of planets

(Newser) - European astronomers have discovered 32 new planets in other solar systems, bringing the total of known exoplanets to over 400. The planets—which range in size from five times the size of Earth to five times the size of Jupiter—were found circling a variety of stars. The new discoveries...

New Hubble Images Dazzle

Refurbished telescope can see further, with more color

(Newser) - NASA released the first shots from the recently upgraded Hubble Space Telescope today, and the results are spectacular. Thanks to the new imagers installed in May, Hubble can now see farther, with greater clarity and a wider color spectrum, reports NPR. Officially, NASA calls it a new beginning for the...

Scientists Spot Galaxy 'Cannibalism'

Andromeda is consuming other galaxies and the Milky Way's on the menu

(Newser) - The vast Andromeda galaxy has been growing by gobbling up neighboring galaxies, reports the BBC. Astronomers mapping the galaxy—at 2.5 million light years away, the Milky Way's closest neighbor—discovered stars within that they believe to be the remnants of dwarf galaxies consumed by Andromeda. The galaxy is...

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...

Space Blob Stumps Scientists

Cosmic blob from the dawn of time confounds theories on early universe

(Newser) - A gigantic blob at the edge of the universe is forcing scientists to rethink their ideas on how galaxies form, reports the BBC. The radiation-emitting object 12.9 billion light years away is one of the most distant—and consequently oldest—things ever seen by astronomers, and is much bigger...

Scientists Say Black Hole Lies at Center of Galaxy

Stars orbit around central nucleus 4M times heavier than sun

(Newser) - A giant black hole sits at the core of our galaxy, say astronomers who participated in a 16-year German study that monitored the movements of 28 stars circling the center of the Milky Way. “Beyond any reasonable doubt,” the stars orbit a core concentration of mass 4 million...

3-D Map Adds Light Years to Concept of Universe

Survey used red shift to find relative distances of heavenly bodies

(Newser) - Telescope photographs of the night sky are compelling, but it’s hard to get a feel for the heavens when you’re Earthbound. The recently completed Sloan Digital Sky Survey can help: It is a 3-D map of the area within 2 billion light years of Earth that allows the...

Dutch Teacher Discovers Green 'Space Ghost'

Accidental find is hot gas ball reflecting far-off galactic light

(Newser) - A Dutch schoolteacher earned her moment in the sun by discovering a cosmic ball of gas some have labeled a space “ghost,” NPR reports. Hanny van Arkel, 25, was working as a volunteer with a galaxy-classifying website when she came upon what “looked like a regular galaxy...

New Planets Yield Hopes of Life Beyond

Rocky, Earth-like orbs appear to be out there; might we indeed have company?

(Newser) - The discovery, announced last week, that rocky, Earth-sized planets appear to be circling sun-sized stars in our own galaxy should thrill the closet Star Trek geek in all of us, Natalie Angier writes in the New York Times. "If planets abound, scientists suspect that life abounds, too, at least...

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...
