14 Galaxy Megamerger May Spawn The Most Massive Single Thing In The Universe

12.4 billion light years away 14 galaxies are merging into a colossus. Astronomers discovered the group using the 394-inch (10-meter) South Pole Telescope and examined it in detail with the Atacama Large Millimeter Array (ALMA) in Chile. Both scopes look like big radio dishes and study the sky in “submillimeter” light just beyond the infrared…

Gaia’s Gift — The Lowdown On 1.7 Billion Stars

There are about 9,000 stars in total visible with the naked eye from a dark sky anywhere on planet Earth. In 1989, a star catalog was compiled to help the Hubble Space Telescope target objects of interest in space. It contained about 20 million stars. Last week, the European Space Agency’s Gaia mission released a…

Astronomers Discover Most Distant Star ‘Icarus’ In Rare Cosmic Alignment

We’ve got a new distance record! Hubble has gazed across 9 billion light years and spotted the most distant star ever seen. Nicknamed Icarus, it’s a massive blue supergiant but so faint that even the biggest telescopes would never have detected it were it not for a lucky accident. A massive foreground galaxy cluster happens…

See-Through Galaxy Has Almost No Dark Matter — What’s Going On?

An international team of researchers have uncovered an amazing new creature in the cosmic zoo — a galaxy relatively close to the Milky Way that’s missing most if not all of its dark matter. The discovery, which appeared on March 28 in the journal Nature, has quickly gotten astronomers’ attention. Current theory requires dark matter…

Behold Hubble’s Cosmic Snake!

If you can’t wrap your head around every aspect of Einstein’s Theory of Relativity, that’s understandable. Neither can I. But when it comes to massive objects warping the fabric of space — one of its more dramatic predictions — the Hubble Space Telescope help us make sense of this bizarre phenomenon. Hubble recently captured a…
