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

A futuristic technique conceptualized by Stanford scientists could enable astronomical imaging far more advanced than any present today.

Earth-based telescopes that look that far back to the big bang (BB) 13.8 billion years ago are unable to resolve the relevant details.

Astronomers have identified a rapidly growing black hole in the early universe that is considered a crucial "missing link".

Astronomers have found a slimmer type of red giant star for the first time. These stars have undergone dramatic weight loss.

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.

NASA has more than 20 Earth-observing satellites that give researchers a global perspective on the interconnected Earth system.

Astronomers have used a new technique to confirm a real-life Tatooine, the fictional planet with two suns that was home to Luke Skywalker.

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.

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.

Dozens of space-based telescopes operate near Earth and provide incredible images of the universe. Imagine a telescope in the outer system.

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

The lightweight flexible holographic lenses, many meters in diameter, could be rolled for launch and unfurled in space.

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

Scientists have discovered stars unexpectedly blasting out radio waves, possibly indicating the existence of hidden planets.

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