Meet Arrokoth: Ultima Thule, the Most Distant Object Ever Explored, Has a New Name

The small body visited by NASA's New Horizons spacecraft on Jan. 1 is now officially known as Arrokoth. Shares. NASA's New Horizons spacecraft flew by the distant Kuiper Belt object Ultima Thule (2014 MU69) on Jan. 1, 2019. The object, the most distant ...

Miss the Mercury Transit of 2019? You'll Have to Wait 13 Years for the Next One

If you missed Mercury's journey across the sun Monday (Nov. 11), you're in for a bit of a wait for the next sun-transiting planetary occasion. It's going to be more than a decade until the next transit of Mercury, which will occur on Nov. 13, 2032. But that's not as ...

A Star Ejected from the Milky Way's 'Heart of Darkness' Has Reached a Mind-Blowing Speed

As humankind's ancestors were learning to walk upright, a star was launched out of the supermassive black hole at the center of our galaxy at a staggering 3.7 million mph (6 million km/h). Five million years after this dramatic ejection, a group of researchers, ...

The Curiosity rover detects oxygen behaving strangely on Mars

(CNN) Since it landed in Gale Crater in 2012, the Curiosity rover has been studying the Martian surface beneath its wheels to learn more about the planet's history. But Curiosity also stuck its nose in the air for a big sniff to understand the Martian atmosphere.

NASA's Next Mars Rover Treks into Red Planet Conditions

NASA's Mars 2020 rover was moved into a vacuum chamber and tested under Mars-like environmental conditions to prepare for its launch to the Red Planet next summer. A new time-lapse video shows engineers at NASA's Jet Propulsion Laboratory (JPL) in ...

If I Touched the Moon, What Would It Feel Like?

The New York Times

Twelve people have walked on the moon since humans landed there 50 years ago, but no one has ever directly touched its surface. Those astronauts wore their spacesuits outside the lander. No one ever took off a glove or a boot while standing on the moon.

Is there life on super-Earths? The answer could lie in their cores

Rocky planets larger than our own, so-called super-Earths, are surprisingly abundant in our Galaxy, and stand as the most likely planets to be habitable. Getting a better idea of their interior structures will help predict whether different planets are able to ...

First study to combine 3-D climate modeling with chemistry refines which exoplanets are potentially habitable

In order to search for life in outer space, astronomers first need to know where to look. A new Northwestern University study will help astronomers narrow down the search. The research team is the first to combine 3-D climate modeling with atmospheric ...

Physics experiment with ultrafast laser pulses produces a previously unseen phase of matter

Adding energy to any material, such as by heating it, almost always makes its structure less orderly. Ice, for example, with its crystalline structure, melts to become liquid water, with no order at all. But in new experiments by physicists at MIT and elsewhere, the ...
