Space photo of the week: Bizarre 1-armed spiral galaxy stuns Hubble scientists
Astronomers used the Hubble Space Telescope to image "peculiar" galaxy Arp 184 (NGC 1961) about 190 million light-years away. Remarkably, the spiral galaxy has only one visible arm.
Space photo of the week: Record-breaking James Webb telescope image captures 1,678 galaxy groups at once
Astronomers used the James Webb Space Telescope for the largest and deepest sample of galaxy groups, some of which were up to 12 billion light-years away.
Amateur astronomer captures detailed photos of Croc's Eye and Whirlpool galaxies from backyard observatory
The Croc's Eye and Whirlpool galaxies shine in astrophotography captured by Vermont-based night sky enthusiast Dr. Michele Hernandez Bayliss.
Astronomers discover giant 'bridge' in space that could finally solve a violent galactic mystery
Scientists have found evidence for a cosmic collision in the Perseus cluster, a group of thousands of galaxies not far from our own.
How many planets are in the universe?
We currently know of more than 5,800 planets beyond the solar system, but we've only found the tiniest fraction of the exoplanets that astronomers think lie elsewhere in the universe.
The universe's 'missing matter' may have finally been found
About half of the non-dark matter in the universe cannot be accounted for by stars and galaxies alone. Now, scientists say previously undetected clouds of hydrogen gas could finally reveal it.
James Webb telescope spots Milky Way's long-lost 'twin' near the dawn of time
The James Webb Space Telescope has discovered Zhúlóng, a candidate for the most distant spiral galaxy in the universe. The perplexing Milky Way 'twin' dates to 1 billion years after the Big Bang, and appears too big to explain.
Record-breaking 'dead' galaxy discovered by JWST lived fast and died young in the early universe
The most distant and earliest "dead" massive galaxy ever seen shows some galaxies lived fast and died young shortly after the Big Bang.
Gaia telescope retires: Scientists bid farewell to 'the discovery machine of the decade' that mapped 2 billion Milky Way stars
After 11 years mapping the Milky Way, the European Space Agency's Gaia space telescope has retired. Scientists hailed it as "the discovery machine of the decade."
NASA's SPHEREx telescope 'opens its eyes on the universe', taking stunning debut image of 100,000 galaxies and stars
SPHEREx's first images — containing roughly 100,000 points of light stars, galaxies and nebulae — have confirmed that the telescope is working according to its design.
