JWST observations of galaxy cluster MACS J1149 show gravitational lensing used by CANUCS to study distant low-mass galaxies across a wide range of cosmic time.

Planets usually stay close to their host stars, tracing steady paths shaped by gravity. Yet some planets break free and drift alone through the Milky Way. Astronomers call these objects free-floating ...

A group of astronomers have made history by capturing an image of a record number of stars from a time when the universe was half its age. The astronomers detected 44 stars in the "Dragon Arc" galaxy, ...

“The cosmological principle is like an ultimate kind of statement of humility,” explains James Adam, astrophysicist at the University of the Western Cape, Cape Town, South Africa, and lead author of ...

Peering into deep space, NASA's James Webb Space Telescope has helped astronomers find places to study gravitational lensing, an effect in which massive objects such as galaxies warp space-time itself ...

For much of the twentieth century, scientists expected the expanding universe to slow over time. The opposite turned out to be true. Space is stretching faster today than in the past, and the precise ...
