Is Time Running Out on Time?

Scientists speculate that the universe is winding down and could one day stop

(Newser) - Astronomers have been scratching their heads for years trying to figure out why exploding stars at the very edge of the universe seem to be moving faster than ones in the middle. Some theories say the acceleration is due to mysterious "dark energy,"but a new one posits...

Mars Draws Near, Shines Bright

Our next chance for this good a look at red planet won't come until 2016

(Newser) - Astronomers of all abilities—and children scanning the night sky for Santa Claus—should be able to see a gleaming Mars as the red planet draws close enough, and into the right position, to outshine Sirius as the brightest evening star. Practically brushing shoulders with Earth—a mere 54,783,...

Milky Way May Have a Hidden Neighbor

Scientist think another galaxy could be cause of odd gravitational pull

(Newser) - We may have new neighbors. Astronomers think they've discovered the cause of a peculiar gravitational pull on the Milky Way—it's another galaxy hidden behind a giant cloud of cosmic dust, the New Scientist reports. The new galaxy could be as close as 3 million light years away, a relative...

Planet Found Orbiting Star

Gas giant is 45 times the size of Earth

(Newser) - Astronomers have found a planet that’s at least 45 times the size of Earth orbiting a star 41 light years away, Space.com reports. The giant ball of gas is the fifth planet discovered around the star 55 Cancri. And while it's not a "twin of our solar...

Astronomers Watch as New Earth-Like Planet Forms

424 light-years away, materials clump together around young star

(Newser) - A massive belt of dust swirling around a young star 424 light-years away could be evidence of a second Earth in the making, Space.com reports. Astronomers observing the area through a NASA space telescope say many of the conditions for forming an Earth-sized planet are present, including moderate temperatures...

Scientists Stumped by Blast From Outer Space

Mysterious pulse could be sign of black hole evaporating or supernovas colliding

(Newser) - A bizarre burst from outer space has scientists talking black holes and colliding stars, Physorg reports — and may even help us "determine the amount of material in intergalactic space," one researcher says. The radio waves, which were measured in milliseconds, might be a blast from 2 superdense...

Hidden Galaxies Come to Light

Scientists discover star systems obscured by quasars

(Newser) - Astronomers have added 14 “invisible galaxies” to their map of the heavens, thanks to an imaginative breakthrough and a massive telescope. Researchers realized that some galaxies might be hidden by the bright lights of quasars behind them, so they scanned quasar data for “dips” where those lights might...

New 'Lucky' System Takes Clearest-Ever Space Pics

Images are twice as sharp as Hubble's

(Newser) - A ground-based optics system has been developed that can take pictures of space twice as sharp as those from the Hubble Telescope. The system uses advanced light detection chips and calculates when the atmosphere is least distorting, the BBC reports. The system gathers together the clear pictures and eliminates distortions...

Western US Awaits Total Lunar Eclipse

Early birds who look to the skies will get an eyeful on Tuesday

(Newser) - The Western US will get a celestial treat early Tuesday morning: a total lunar eclipse. Residents of the Western Hemisphere and eastern Asia will get at least a glimpse of the spectacle, but Europeans will miss out—the moon will be below the horizon. Space.com tells you how to...

Enormous Hole Found in Cosmos

Scientists spot unexpected void a billion light years wide

(Newser) - Astronomers have discovered a mysterious gigantic hole in the universe, reports Space.com. Unlike black holes, created by super dense material, this hole is devoid of matter. It measures nearly a billion light years wide and is 10 billion light years from earth. The hole was discovered by examining input...

Largest Planet Ever Discovered

Huge, lightweight discovery puzzles scientists

(Newser) - Forget Jupiter. Scientists have discovered the largest planet out there—a "puffy" space mass almost twice the size of our solar system's gas giant. But the find is posing more questions than answers, Space.com reports: TrES-4’s mass is large but its density is about the same as...

Most Massive Star Ever Weighs In

Astronomers say hefty gas giant is 100 times heavier than the sun

(Newser) - The most massive star yet discovered has been "weighed," astronomers say, and it tips the scales at a whopping 114 times the mass of the sun. The enormous star forms the bigger half of a rapidly orbiting binary system and it far outstrips both its companion star and...

Crop of New Planets Means Better Chance of Life

Rapid discovery of planets outside our solar system ups odds one has liquid water

(Newser) - Astronomers who've spotted 28 new planets in the past year are gaining confidence that other solar systems may be able to support life like ours. One researcher estimated that there are probably "tens of billions" of planets with habitable conditions, most important of which is hospitality to water.

Hubble Finds Dark Matter

(Newser) - Astronomers have discovered a ring of dark matter in a galaxy cluster about 5 billion light years away. The Hubble Telescope turned up an anomaly in the way stars in the area appear, which researchers think is a distortion caused by the intense gravity of the galactic "glue" holding...

Earth-Like Planet Could Sustain Life

Scientists claim major breakthrough in search for extraterrestrial life

(Newser) - Astronomers have discovered a planet that can sustain liquid water, the prerequisite for life as we understand it. Named Gliese 581 C, the new planet orbits a red dwarf star in what's called the "Goldilocks zone"—not so close that water melts, and not so far that it...
