Barred Spiral Galaxy NGC 2608, Surrounded by Many Many Other Galaxies
17 Jun 00:00:11 | Universe Today
Meet NGC 2608, a barred spiral galaxy about 93 million light years away, in the constellation Cancer. Also called Arp 12, it’s about 62,000 light years across, smaller than the Milky Way by a fair margin. The Hubble Space Telescope captured this image with its Wide-Field Camera 3 (WFC3). Depending on your age, you may …

Space Dust Delivered Water to Vesta, Could it Have Done the Same for Earth
16 Jun 00:00:13 | Universe Today
One of the most enduring questions about Earth regards the origins of its water. Where did it come from? One widely-held theory gives comets the honor of bringing water to Earth. Another one says that Earth’s water came when a protoplanet crashed into early Earth, not only delivering a vast quantity of water, but creating …

Hilarious Supercut of Astronauts Falling on the Moon
16 Jun 00:00:13 | Universe Today
The Apollo astronauts walked on the Moon, yes. But they also hopped, bounded, and shuffled. And sometimes they fell, spectacularly. That caused a lot of consternation back on the Earth, especially for the engineers who designed the Apollo spacesuits. James McBarron was an aerospace technologist who worked on spacesuits for every NASA program, from Mercury …

Early Life Was Pumping Out Oxygen, But the Earth?s Mantle Was Absorbing it
15 Jun 00:00:12 | Universe Today
About 2.4 billion years ago, everything changed for Earth. That was the time of the Great Oxidation Event (GOE), when photosynthetic bacteria flooded the atmosphere with oxygen, banishing early, non-oxygen using lifeforms to the fringes of the Earth. The GOE laid the groundwork for the Earth we see today, dominated by complex, oxygen-breathing lifeforms. But …

This is a Binary Star in the Process of Formation
14 Jun 00:00:23 | Universe Today
About 460 light years away lies the Rho Ophiuchi cloud complex. It’s a molecular cloud?an active star-forming region?and it’s one of the closest ones. R. Ophiuchi is a dark nebula, a region so thick with dust that the visible light from stars is almost completely obscured. But scientists working with ALMA have pin-pointed a pair …

A 2nd Planet has been Confirmed for Proxima Centauri
13 Jun 00:00:16 | Universe Today
Our closest stellar neighbour is Proxima Centauri, a small red dwarf star about 4.2 light years away from us. It’s the third member of the Alpha Centauri group, and even though it’s so close, it can’t be seen with the naked eye. In 2016 astronomers discovered a planet orbiting Proxima Centuari, named Proxima Centauri b. …
