Once upon a time, the Milky Way died. It may have been several billions of years ago, but the stars in the sky paint a picture of the galaxy’s tumultuous history that has huge implications in galaxy evolution.
Scientists have glimpsed thousands of galaxies in a distant portion of the universe through a powerful telescope, providing new insights into the “Golden Age” of galaxy formation.
Astronomers found a rare type of growing galaxy that appears to feed off stolen gases.
In the beginning, there was only darkness... Then stars began to fill the heavens, lighting our Universe. No matter what your denomination or beliefs, this is one point you likely won't dispute. Astronomers have long been fascinated with the dawn of light, and now, with the help of the Hubble Space Telescope, they believe they have determined how that beginning ended.
The Hubble Space Telescope recently captured images of some eerie and beautiful objects floating around space. A series of green and ghostly wisps were recently spotted by the unmanned orbital telescope, betraying the past presence of quasars, the brightest objects in the Universe.
Treasure seekers have found the haul of a lifetime, but it wasn't in some ancient temple or mysterious island. Instead, it was in the sky. Researchers using two of the European Space Agency's (ESA) impressive space telescopes have successfully identified what they are calling a "treasure chest" of ancient galaxy clusters, which could help explain how the Universe came to be the way it is today.
Apparently proper hygiene is a bit different for growing galaxies, as a long "shower" could be a very bad thing. NASA's Chandra X-ray Observatory and Hubble Space Telescope have revealed a young galaxy cluster that is riddled with holes. Research now reveals that it's growth was stunted by its very own black hole after unusual cosmic precipitation halted an important cycle.
Researchers have discovered that soon after the Big Bang, some of the first galaxies may have been in a rush to make stars. That's at least the case for A1689-zD1, an ancient galaxy that's an incredibly long way from Earth - so far away that we are seeing it from when the Universe was a mere 700 million years old.
Researchers are now proposing that evidence of the origins of life may very well be hidden on the Moon, where the earliest organic traces in existence may have been preserved in lava during the satellite's fiery adolescence.
An analysis of water vapors from comet 67P/Churyumov-Gerasimenko, the quarry of the Rosetta Spacecraft and its history-making Philae lander, has revealed that its water is not at all like Earth's. This revelation casts some serious doubt on one theory of how our oceans formed, and raises many new questions.
When you think of stars, you likely think of incredibly hot balls of blazing fire and writhing plasma. However, experts have long known that for a new star to be born, a stellar nursery actually needs some cool conditions. Now, astronomers have observed how a wave of hot gas can extinguish star formation entirely, exposing new secrets of the Universe.
Back in 2012, a meteorite managed to puncture through Earth's atmosphere and slam into the ground of California's Gold Country - a historic region that attracted waves of 49ers during the 1849 gold rush. Ironically, this "Gold Rush meteorite" doesn't boast any yellow precious metals. Instead, it seems to be packed full of diamonds and other treasures.
Using the powerful Atacama Large Millimeter/submillimeter Array (ALMA) telescope in Chile, astronomers have captured the best image ever showing how planets are born, thereby providing a portal to our solar system's past.
NASA's Spitzer Space Telescope (SST) has recently unveiled new images of an uniquely shaped galaxy that looks a lot like a spoked wheel. What makes this galaxy particularly unique is the fact that it is quite old, and yet is characterized by a ring of freshly born stars.
Not every garden is immediately flush with countless flowers. Astronomers say the same is true for galaxies, in that some galaxies "bloom" much later in their long lives, pumping out stars at delayed rate. Now, a new study details why some galaxies appear to produce stars at a much slower rate compared to others.
