A unique new instrument, coupled with a powerful telescope and a little help from nature, enables scientists to peer into galactic nurseries

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.

A major new space telescope searching for 'Earth 2.0'—to Succeed Hubble and the James Webb Space Telescope —is one step closer to reality.

Thousands of alien worlds are known to orbit stars beyond our solar system. And many more worlds, possibly harboring life.

Astronomers have reported the discovery of a structure thought to be a "protocluster" of galaxies 11 billion light-years from Earth.

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

The James Webb Space Telescope, which astronomers hope will herald a new era of discovery, will launch on December 18, 2021.

A new open data nonprofit scientific initiative by Avi Loeb will use a network of telescopes, cameras and computers to scan for alien life
