The larger the mirror, the more light is collected. This means that we can see farther back in time to observe star and galaxy formation.

For more than 60 years, scientists have been searching for possible signs that would indicate the existence of extraterrestrial intelligence

A powerful radio-wave laser, called a ‘megamaser’, has been observed by the MeerKAT telescope in South Africa.

A state-of-the-art asteroid alert system can scan the entire dark sky every 24 hours for dangerous bodies that could plummet toward Earth.

Astronomers have discovered an unusually massive black hole at the heart of one of the Milky Way’s dwarf satellite galaxies, called Leo I.

Among other goals, James Webb will search the atmospheres of alien planets for what scientists call "biosignatures" -- the presence of life.

When NASA's James Webb Space Telescope launches, it will undergo one of the most harrowing deployment processes any spacecraft has endured.

How do we find Earth-like planets outside our solar system? Send a giant structure that blocks starlight so that astronomers can see further
