Every now and then, astronomers spy a runaway star, one that’s hurling itself across its galaxy at breakneck speeds. But stars aren’t the only things that occasionally go beserker in the cosmic void: Galaxies themselves will sometimes depart home, never to return. »
New research from Western University in Ontario suggests the universe’s first stars amassed in conglomerations so bright they shone with the power of a hundred million suns. »
The first exoplanet ever discovered is now the first exoplanet ever observed in visible light. 51 Pegasi B, a super Jupiter located about 50 light-years from Earth, was detected by comparing the light bouncing off its highly reflective surface to the spectral signature of its host star. It’s hoped the new technique… »
A few weeks ago, NASA chief scientist Ellen Stofan made news by saying, “I think we’re going to have strong indications of life beyond Earth within a decade, and I think we’re going to have definitive evidence within 20 to 30 years.” It was a bold statement, but NASA is now backing those words with action. »
By applying the rules of Einsteinian general relativity to data pulled in by the Pan-STARRS telescope, scientist have developed two distinct simulations of supermassive black hole mergers that are considered the best yet. »
This year’s Lyrid meteor shower is expected to peak between midnight and dawn on Wednesday, April 22 and Thursday, April 23rd. Here’s what you need to know to spot as many meteors as possible. »
NASA’s Dawn spacecraft is settling into its first orbit around dwarf planet Ceres. And as you can see from this newly released animation, the view is getting to be quite spectacular. »
This week, scientists with the Dark Energy Survey (DES) collaboration released the first in a series of detailed maps charting the distribution of dark matter inferred from its gravitational effects. The new maps confirm current theories that suggest galaxies will form where large concentrations of dark matter exist.
On the request of NASA, the U.S. Geological Survey has prepared two highly detailed maps of the Moon. Fortunately, they've also been made available to the public, so check 'em out in all their lunar glory. »
These two blobs may not look like much, but it's a watershed moment for the New Horizons mission. It's the first color photo of Pluto and its largest moon, Charon, taken by an approaching spacecraft. Taken on April 9 from a distance of 71-million miles, it's a teaser of things to come. »
A pioneering infrared scan of 100,000 galaxies by Penn State astronomers has failed to detect any signs of galaxy-spanning extraterrestrial supercivilizations. This result, though very preliminary, may be a sign that aliens aren't capable of conquering entire galaxies. »
After months of anticipation, NASA scientists have finally produced a detailed color map of Ceres. Our first detailed look at the dwarf planet's pitted surface reveals it is a geologically complex place. »
Four hundred and fifty five light years away sits a newborn star that bears striking resemblance to our Sun. It’s awash in a sea of complex organic molecules which could, one day, coalesce to form proteins, nucleic acids, even life itself.
Our sun has only been around for 4.5 billion years — which means it missed the cute early years of the Milky Way galaxy. If you were standing on a planet 10 billion years ago, when the Milky Way was relatively young, the night sky would have looked very different. »
