The observatory has achieved this milestone over 28 years in space, even though it was never designed to be a comet hunter.
NASA invested hundreds of millions of dollars in potential replacements for the International Space Station (ISS), with Jeff Bezos’ Orbital Reef passing crucial milestones.
Using NASA’s Juno spacecraft, scientists have calculated the rate of oxygen production on Jupiter’s moon Europa — the first time any spacecraft had directly measured charged oxygen and hydrogen particles from the moon’s atmosphere.
New measurements by NASA’s New Horizons spacecraft show higher than model-predicted levels of interstellar dust as the spacecraft approaches the putative outer edge of the Kuiper Belt.
On new recently released NASA images show the moons of Saturn in all their glory, as if they came straight out of the pages of science fiction.
A “super-Earth” ripe for further investigation orbits a small, reddish star that is, by astronomical standards, fairly close to us – only 137 light-years away.
It’s oh-so-easy to be absolutely mesmerized by these spiral galaxies. Follow their clearly defined arms, which are brimming with stars, to their centers, where there may be old star clusters and – sometimes – active supermassive black holes.
Astronomers using NASA's Hubble Space Telescope observed the smallest exoplanet where water vapor has been detected in the atmosphere.
NASA and Lockheed Martin formally debuted the agency’s X-59 quiet supersonic aircraft Friday. Using this one-of-a-kind experimental airplane, NASA aims to gather data that could revolutionize air travel.
NASA astronomers have discovered an unexpected "signal" coming from outside our galaxy, which they can't explain.
Astronomers using NASA's Hubble Space Telescope have found a rare fast radio burst (FRB). This new FRB is particularly weird because it erupted halfway across the universe, making it the farthest and most powerful example detected to date.
A team of scientists has come up with a wild new way to visit our closest star Proxima Centauri using a swarm of tiny spacecraft.
Engineers at NASA successfully test-fired an innovative Rotating Detonation Rocket Engine combustor, a potentially revolutionary propulsion technology that could deliver a lander to the lunar surface or propel a spacecraft to Mars.
The video, featuring a cat named Taters, was sent back from nearly 19 million miles away by NASA’s laser communications demonstration, marking a historic milestone.
A study zooms in on data that NASA’s Cassini gathered at Saturn’s icy moon and finds evidence of a key ingredient for life and a supercharged source of energy to fuel it.
