One of the first images the James Webb Space Telescope ever captured was only possible thanks to a gravitational lens. Its latest is another example of this phenomenon, this time featuring a galaxy called the Cosmic Seahorse.
The James Webb Space Telescope has recently captured a large spiral galaxy that resembles Earth's own Milky Way Galaxy that exists a little over a billion light years away.
Hubble is getting into the Halloween spirit with its photo of the galaxy cluster Abell 611. This, like all galaxy clusters, is a cosmic mystery to astronomers who aren't sure how it is able to stay together since there doesn't seem to be enough mass to keep it from flying apart.
The Hubble Space Telescope has captured a new celestial image that depicts two objects, described as "glowing clumps," that are found around some newborn stars.
The Solar Orbiter mission recently flew close to the Sun to show Earth's nearest star over 20 days from September 20 to October 10.
Even though the James Webb Space Telescope tends to steal the space-themed headlines lately, the Hubble Space Telescope is still capturing incredible photos of the universe, including this galactic pair that are so close to one another that they are distorted by each other's gravity.
The James Webb Space Telescope (JWST) team has translated some of the telescope's first photos into music. Called sonification, the goal is to make the JWST's image and data understandable through sound to help listeners create their own mental images.
The James Webb Space Telescope's (JWST) mid-infrared instrument (MIRI) has been used to capture a gorgeous and mesmerizing photo of the heart of galaxy M74, also known as the Phantom Galaxy.
Fans of astrophotography are currently feasting thanks to the James Webb Space Telescope, but Hubble isn't ready to be forgotten yet. Its latest capture is a gorgeous glittering star cluster in the constellation Sagittarius.
The James Webb Space Telescope (JWST) has aimed its impressive camera system relatively close to home and captured a pair of gorgeous photos of Jupiter's auroras.
While the James Webb Space Telescope (JWST) has dominated headlines, the Hubble Space Telescope shouldn't be forgotten. The legendary observatory recently captured this gorgeous photo that showcases the colors of the Orion Nebula.
The European Space Agency (ESA) has published a video that puts into perspective just how far away the latest target of the James Webb Space Telescope (JWST), the Cartwheel Galaxy, is.
The European Space Agency has released stunning images of the enormous Valles Marineris canyon taken by the Mars Express.
NASA has finally published the first colorized, full-resolution photos captured by the James Webb Space Telescope and the detail and resolution of the images is incredible, especially when compared to the images of these same cosmic objects captured by Hubble.
The James Webb Space Telescope's first full-color photo has been revealed, and comparing it side-by-side to the same area that was imaged by Hubble shows just how much more detail Webb’s camera is capable of capturing.
United States President Joe Biden has shared the first full-color photo taken by the James Webb Space Telescope as a preview of the full set of five images that will be shared publicly on July 12.
NASA's Hubble Space Telescope has calibrated more than 40 "milepost markers" of space and time over the course of the last 30 years that scientists are using to measure the expansion of the universe.
On Monday, large portions of the planet were treated to a total lunar eclipse. And while there were many excellent opportunities to photograph it from Earth, one astronaut shared her photos that were taken from space.
