No danger, says Nasa, from delivery truck-sized asteroid that was discovered on Saturday and will pass lower than communication satellites

Using the James Webb Space Telescope, astronomers discover a rich catalog of frigid interstellar ice in the depths of a dark, dense molecular cloud.

The agency wants the technology for use in crewed missions to Mars.

Since July 2022, the James Webb Space Telescope has delivered stunning news: it's seeing galaxies orders of magnitude brighter in the early universe then what science anticipated.

A team of astrophysicists has discovered a binary pair of ultra-cool dwarfs so close together that they look like a single star. They’re remarkable because they only take 20.5 hours to orbit each other, meaning their year is less than one Earth Day. They’re also much older than similar systems.

Aspiring Japanese astronauts have taken their final exams on a mock lunar surface at a training facility near Tokyo, with the successful candidates to be revealed next month.

An international team of scientists, including NYU Abu Dhabi researcher Nikolaos Georgakarakos and others from the U.S., Japan, and China, led by Jian Li from Nanjing University, has developed new insights that may explain the numerical asymmetry of the L4 and L5 Jupiter Trojan swarms, two clusters containing more than 10,000 asteroids that move along Jupiter's orbital path around the sun.

180 rockets lifted off successfully, with SpaceX driving the pace.

Outpost recently tested a stratospheric paraglider to return space tech ahead of orbital ventures for NASA and other companies later in the 2020s.

The astronomical phenomenon gave skywatchers a good view of Mercury, Venus, Mars, Jupiter and Saturn with the naked eye.

Studying the large-scale structure of our galaxy isn’t easy. We don’t have a clear view of the Milky Way’s shape and features like we do of other galaxies, largely because we live within it. But we do have some advantages. From within, we’re able to carry out close-up surveys of the Milky Way’s stellar population … Continue reading "Is the Milky Way… Normal?"

A new study shows that some tidally-locked explanets around red dwarf stars could be partly habitable. But the land-ocean ratio is critical.

NASA was able to capture a "gallery of objects ranging from small fountains to burbling behemoths" deep in space: "It's like finding buried treasure."

Surrounded by a vast ocean underneath a thick ice shell, Enceladus is a hot candidate for potentially harboring alien life. A team of researchers led by the University of Arizona concluded that a future mission could provide answers even without landing on the tiny world.

Human-built spacecraft have been exploring other planets for a full 60 years. On Dec. 14, 1962, a NASA spacecraft called Mariner 2 flew past Venus in the first-ever planetary flyby. The maneuver gave the spacecraft 42 minutes to observe what scientists now consider Earth's hellish twin — whose hidden surface at the time was thought to be lush, tropical jungle or swamp.

A major telescope upgrade has peered through to the distant Universe to reveal the spectra of a pair of galaxies 280 million light years away from Earth.

December 7, 1972 was the launch of the final mission in NASA's Apollo moon program. Fifty years later, NASA finally seems poised to return people to the lunar surface.

"I would say that we’re going to try our best to get there."

“It’s probably swallowing the star at the rate of half the mass of the Sun per year.”

"It’s really hard to articulate what the feeling is."
