Two cosmic love birds lit the way to the discovery of dark matter, and a new Hubble image features a behemoth galaxy that played a part in the groundbreaking finding.

When scientists search for alien planets, they get a special thrill when they find one that seems to reflect our own world back to us.

Astronomers using NASA's Transiting Exoplanet Survey Satellite found that the star ancient Egyptians once used as their North Star is part of a binary pair of stars that eclipse one another.

It turns out that dark matter forms smaller "clumps" than scientists thought, confirming a fundamental prediction about the mysterious substance.

Nobody knew they'd be this bright.

We just might need new physics to get out of this mess.

Staff at Puerto Rico's iconic Arecibo Observatory are monitoring the facility for potential damage in the midst of a spate of earthquakes rocking the island.

The jets emanating from a famous black hole are cruising along at near light speed, according to new observations.

Astrophysicists are deep in the throes of a process they conduct every 10 years to set scientific priorities for the field; the results could determine which missions fly and which don't.

Mysterious ultra-fast pinpricks of radio energy keep lighting up the night sky and nobody knows why.

A U.S. facility — designed in part to solve the mysteries of dark matter — now officially carries the name of the scientist who concluded that the elusive substance must exist.

TOI 700 d is a landmark discovery for NASA's Transiting Exoplanet Survey Satellite.

For the second time ever, the Laser Interferometer Gravitational-Wave Observatory (LIGO) has spotted two ultradense stellar remnants known as neutron stars violently crashing together.

Astronomers kicked off 2020 by welcoming the 30th anniversary year of NASA's venerable Hubble Space Telescope in Honolulu at their largest annual gathering.

NASA's next flagship space telescope is still on track for a launch in March 2021 despite longstanding scheduling concerns, according to agency personnel.

The American Astronomical Society's biggest annual gathering, a conference dubbed the "Super Bowl of astronomy," kicks off in Hawaii today (Jan. 6) and it's the largest one in history.
