An image from the Dark Energy Camera shows an act of galactic cannibalism, with a spiral galaxy devouring a nearby dwarf galaxy that wandered into its path.
A Neptune-sized planet orbits close enough to its star that it is bombarded by dramatic flares which cook the planet with radiation and strip its atmosphere.
Newborn stars are often active and glow brightly, but on rare occasions they create something epic: a vast two-lobed structure called a Herbig-Haro object.
This week's image from the Hubble Space Telescope shows a stunning view of a spiral galaxy called UGC 12295, located nearly 200 million light-years away.
This Hubble image is composed of two different exposures which have been merged together, showing star BD+17 2217 shining over the background galaxy Arp 263.
Recently astronomers discovered a very unusual example of a white dwarf: one that seems to have one side composed of hydrogen and the other side of helium.
Last year, NASA deliberately crashed a spacecraft into an asteroid. Now, Hubble has observed that a number of boulders have been ejected from the asteroid.
Researchers used the James Webb Space Telescope to identify grains of dust from the early universe, which could have been produced by the earliest supernovas.
Nebulae are some of the most beautiful structures to be found in space. A new image from the Gemini South telescope shows an usual double-lobed nebula.
The molecules are associated with life but can be created by other processes. So they aren't proof there was life there, but they are life's building blocks.
Venus is one of the most brutally inhospitable places in our solar system, but many scientists think life could have thrived there at one point. Here's why.
Today marks the one-year anniversary of the first images from the James Webb Space Telescope, and to celebrate NASA has shared another gorgeous image of space.
The visualization shows a small part of a region called the Extended Groth Strip, covering 5,000 galaxies and zooming in toward the distant Maisie's galaxy.
Astronomers are getting a new instrument to probe the mysteries of dark matter with the launch of the Euclid telescope this Saturday. Here's how to watch.
The Juno spacecraft made its 49th close flyby of Jupiter earlier this year, and NASA has shared stunning images taken as it whizzed by the planet's cloud tops.
Slowing a spacecraft down takes tons of fuel, so scientists are eager to try something different on Venus: slowing down with the help of the planet's atmosphere
