The incoming administration of President-elect Joe Biden and Vice President-elect Kamala Harris may very well make history with their choice to lead the 62-year-old U.S. space agency.

"It was as if somebody had just created a telescope that was a time machine."

The collapse of the iconic radio telescope at the Arecibo Observatory in Puerto Rico last month has left astronomers with a host of questions about what went wrong and what comes next.

Scientists were able to measure the orbit of exoplanet GOT 'EM-1b, a gas giant nearly 1,300 light-years from Earth.

Astronomers may be getting closer to discovering as-yet hidden cosmic secrets, such as the nature of dark matter and the presence of widespread distortions in space-time.

A rocky exoplanet known as TOI-561b was found circling one of the oldest stars in our Milky Way galaxy. The exoplanet is about 50% larger than Earth.

Astronomers just confirmed the existence of KOI-5Ab, which was first flagged as a potential planet by NASA's pioneering Kepler space telescope way back in 2009.

The American Astronomical Society (AAS) is making the most of online opportunities during its 237th meeting, which will fully take place virtually this week due to the coronavirus pandemic.

Two incredibly strange celestial objects whose discoveries trace, in part, to observatories at the summit of Maunakea now carry the peak with them in official names inspired by Hawaiian culture.

You can't rush a superdense star as it gobbles up bites of a neighbor for nearly two weeks before shooting off a burst of X-rays thousands of times brighter than our sun.

A year ago, scientists captured the unphotographable when the Event Horizon Telescope published a fiery orange ring on a black background that became instantly recognizable.

The neutron-star merger that showered the solar system with its precious metals was fairly close and fairly recent.

What could a massive new telescope in Hawaii teach astronomers about the universe — and why are some native Hawaiians fiercely opposed to the project?

Looking for life traditionally starts with finding a planet with the right temperature — but scientists are working to find new criteria for tracking down potentially habitable worlds.

NASA faces a difficult choice: What does the agency want to select as its next big space telescope, the instrument that will shape scientists' research in the 2040s?

Stars don't see gender, and now, NASA is working to not see it either when allocating telescope time to scientists, inspired by a successful experiment with the Hubble Space Telescope.

Pluto's discovery wouldn't have been possible, astronomers have realized, without the calculations of a mathematician whom history has forgotten.

Coronal mass ejections aren't known for being subtle: Each such event can fling huge amounts of the soup of charged particles called plasma off the sun and out into the solar system.

In order to study planets, you have to look at stars, so you may as well analyze what you see.
