The observed near flatness of galactic rotation curves has long been interpreted as evidence for large amounts of non-baryonic dark matter. Here we show that this phenom ...

A new image of a portion of the Helix Nebula from NASA’s James Webb Space Telescope (JWST) highlights cometlike knots, fierce ...

Within the image, thick clouds of cold hydrogen gas arrange themselves into ridges and wispy filaments. The deep red tones ...

The "Cosmic Grapes" galaxy formed just 900 million years after the Big Bang, revealing a never-before-seen structure.

A Simon Fraser University cosmologist believes his team's new research may bring them a step closer to cracking one of ...

Astronomers have chased hypervelocity stars for more than a century. These rare objects move so fast that the Milky Way ...

But first, a bit of space telescope history. One of the most powerful space-based telescopes to be launched into the Earth’s ...

A strange, starless object is forcing astronomers to rethink how galaxies are born. Using the Hubble Space Telescope, NASA scientists have identified a massive cloud of dark matter and gas that looks ...

Astronomers used gravitational lensing to detect a supernova 10 billion light-years away, providing spatially separated images that help study cosmic expansion and early Universe events.

In the vast silence of intergalactic space, some structures remain hidden not because of their distance, but because they emit no light at all. They are not stars, and they are not galaxies in the ...

Although scientists have long predicted the existence of these elusive objects, confirmation only came after Hubble observations showed the cloud to be completely star-free.

On Oct. 4, 1923, Edwin Hubble took a photographic plate of the Andromeda Nebula (as it was known then) using the 100-inch Hooker telescope at Mount Wilson. The next night, Oct. 5th, he took another ...
