It’s the oldest light in the universe.

The stellar systems—which astronomers describe as "blue blobs"—are located within the relatively nearby Virgo galaxy cluster.

It has taken eight months to test and calibrate all of the instruments and modes of the James Webb Space Telescope. A scientist on the team explains what it took to get Webb up and running.

Just 33 light years from Earth, the system appears to host two rocky, Earth-sized planets.

The varied surface suggests a dynamic history, which could include metallic eruptions, asteroid-shaking impacts, and a lost rocky mantle.

The unusual behaviour of sulphur in Venus’ atmosphere cannot be explained by an ‘aerial’ form of extra-terrestrial life, according to a new study.

New data may settle dispute about the universe’s true expansion rate.

A Japanese spacecraft grabbed a handful of dust from the asteroid Ryugu. Scientists have now analyzed a sample.

Two MIT professors and five alumni recognized for outstanding contributions to astronomy research, education, and communication.

Planets may form differently around binary stars than they do near loners like our Sun. The finding could lead to new targets in the search for alien life.
