In new images from NASA's James Webb Space Telescope, the galaxy appears as a long, warped arc teaming with star clusters that resemble a swarm of lightning bugs on a warm summer night.

JWST has proven to be ideal for the discovery, researchers say, thanks to the telescope's sharp infrared eyes that detect the asteroids' thermal emissions. These infrared emissions are much ...

In the years since, researchers using the Hubble Space Telescope have observed that the current expansion rate, called the Hubble constant, is faster than what standard cosmology models estimate ...

A grand spiral galaxy takes center stage in a new image from the Hubble Space Telescope. The galaxy, known as NGC 5643, is located roughly 40 million light-years from Earth in the constellation Lupus.

The availability of the James Webb Space Telescope is finally giving astronomers the tools they need to measure this aspect of space more accurately. A new study led by Nobel laureate Adam Reiss ...
