Astronomers have observed and identified a new type of thermonuclear stellar explosion — a micronova. It's a million times less powerful than a standard nova and lasts just a few hours.
NASA's Spitzer Space Telescope captured an image of the aptly named Butterfly Nebula, also known as Westerhout 40 (W40).
The $26 billion NASA budget allocation for 2023 will help advance the agency's Artemis program, space and Earth science efforts, X-plane development, and commercial partnerships.
Ax-1's Mission Specialist Eytan Stibbe will perform the Fluidic Telescope Experiment (FLUTE), investigating the use of liquids to construct telescope lenses in microgravity.
The James Webb Space Telescope's MIRI instrument needs to cool down almost to absolute zero, the temperature where the motion of atoms stops, before it can start observing the universe.
NASA's Ingenuity helicopter completed its 24th Martian flight on Sunday (April 3), a short repositioning hop that covered 154 feet (47 meters) in 69.5 seconds.
The public-private partnership is providing internet connectivity to Ukraine, whose cities have been besieged by Russian forces since February.
Researchers have spotted what might be the farthest astronomical object ever found — a galaxy candidate named HD1 that they estimate is 13.5 billion light-years away.
Asteroid 2022 GN1 will pass within 79,000 miles (127,000 kilometers) of Earth, or about one-third of the distance between the Earth and the moon, later this evening.
The Hubble Space Telescope has spotted a young Jupiter-like protoplanet that’s supporting an unusual planetary formation theory, according to a new study.
One of Hubble's latest photos captures the spiral galaxy NGC 5921, which lies just shy of 80 million light-years away from Earth in the constellation Serpens.
The first whiff that humans catch of life beyond Earth might be methane, but scientists will need to tread carefully before declaring a discovery based on the chemical.
Though scientists know there's a supermassive black hole at the center of most galaxies, they can't explain how the gravitational giants formed.
A new study based on NASA and ESA satellite data shows that Arctic sea ice is thinning at a "frightening rate."
REFERENCE Learn all about the northern lights, including the science behind their colors, the display's ancient history and how to see the phenomenon.
As eyes turn to Webb, Hubble reminds us of its stellar imaging power with a mesmerizing new photograph.
The data provided by Webb will be a boon to astronomers around the world. Here's what they hope to learn.
The mysterious Kuiper Belt, home to former planet Pluto and its moon Charon, will be a subject of study for the powerful observatory.
In a paper published today, an international team of researchers has disproved the existence of a black hole in HR 6819.
The Hubble Space Telescope kicked off the Cosmic Evolution Survey (COSMOS) two decades ago, but soon, the newly launched James Webb Space Telescope will join the galaxy-mapping program.
Star clusters are large gravitationally bound groups of stars that are one of the best tools astronomers have to study stellar evolution.
