About half of the non-dark matter in the universe cannot be accounted for by stars and galaxies alone. Now, scientists say previously undetected clouds of hydrogen gas could finally reveal it.

Dark sky proponents mull the rights of nature to battle light pollution. Here's how it would work

Scientists have developed an impossibly thin telescope lens that addresses a key astronomical challenge in a new study funded by NASA and DARPA.

Scientists have made the record-breaking detection of oxygen in an ancient galaxy that existed just 300 million years after the Big Bang. The detection is prompting astronomers to rethink how quickly stars and galaxies formed in the young universe.

March 15, 2025: Our weekly roundup of the latest science in the news, as well as a few fascinating articles to keep you entertained over the weekend.

On March 14, skywatchers in the Americas will be able to see the first of 2025's two total lunar eclipses.

A 'false dusk' will be visible during twilight in February, but only from locations that are free of light pollution. Here's everything you need to know about zodiacal light.

After a Chinese export ban, can America get gallium and germanium from Canada — or will tariffs get in the way?

This NASA/ESA Hubble Space Telescope image features a dusty yet sparkling scene from one of the Milky Way's satellite galaxies, the Large Magellanic

Northwestern University researchers have successfully achieved quantum state transfer over a 30.2-km fiber carrying 400-Gbps C-band classical traffic.

NOAA shared new images taken by the world's first operational space-based coronagraph, CCOR-1, captured during a solar storm outburst.

Light can be directed and steered around bends using a method similar to the way clouds scatter photons, which could lead to advances in medical imaging, cooling systems and even nuclear reactors

Physicists showed that photons can seem to exit a material before entering it, revealing observational evidence of negative time

A bold new study in Physical Review suggests that a wobble detected in Mars' orbit could be the result of dark matter made up of primordial black holes.

A study led by researchers from the Changchun Institute of Optics, Fine Mechanics and Physics of the Chinese Academy of Sciences revealed a novel metal-dielectric film mode filter structure that can flexibly regulate transverse modes in vertical-cavity surface-emitting lasers (VCSELs), which demonstrates the potential of metal apertures in enhancing mode control within VCSELs. The study was published in Sensors.

Scientists have measured the magnetic moment of the muon to unprecedented precision, more than doubling the previous record.

NASA's Artemis campaign will send the first woman and the first person of color to the moon's south polar region, marking humanity's first return to the lunar surface in more than 50 years.

Voyager 2, NASA's longest-running mission, explored Neptune during a historic encounter on Aug. 25, 1989, sending back humanity's first close-ups of the planet.

Seeding Martian skies with metallic nanorods may efficiently start terraforming.
