"This is the final boarding call to keep your name on NASA's Mars 2020 rover before launching it on the Red Planet," NASA officials wrote in …

The possible existence of Planet Nine and its effect on distant objects in the solar system have been fascinated by researchers for hours. But a new study suggests that the theoretical object may not be a giant planet hiding behind Neptune – but rather a primordial black hole. The research, posted in arXiv, a repository for peer-reviewed studies, suggests. that …

(Credit: NAOJ / Harikane et al.) Astronomers have discovered the oldest cluster of galaxies ever seen, originating in the early universe. – nearly 700 million years after the Big Bang. …

A new study suggests that the building blocks of life may not have originated on Earth, but rather giant gas clouds in deep space. The research theorizes that the building blocks of DNA, known as nucleobases, have been spotted in a simulated environment that echoes "interstellar molecular clouds," which may aid researchers in understanding how life started on our planet. …

Black holes on your mind? You're in luck because NASA has a new visualization showing how these immense objects work. Black holes are regions of extremely high density that warp space around them to such an extent that it traps matter and light. If any object goes too close and enters the black hole's point of no return, called the …

After passing too close to a supermassive black hole, the star of this artist's conception is torn into a thin stream of gas, which is then pulled back around the black hole and slams on itself, creating a bright shock and ejecting warmer material.

WASHINGTON (Reuters) – Scientists have uncovered a large black hole that violently wreaked havoc on a doomed star, depicting a rare and chaotic cosmic event from beginning to end for the first time using NASA's planetary hunting telescope. The orbiting of the United States Transiting Exoplanet Survey Satellite, better known as TESS, revealed a detailed timeline of a star of …

The telescope was opened after an asteroid, capable of destroying a city nearly collapsed on Earth two months ago. Classified as a "near-miss", the asteroid was detected only a day before it entered the Earth. Speaking to the asteroid, NASA's planetary defense officer Lindley Johnson admitted: "This one has surrendered to us and this is an interesting story about the …
