Astronomers are once again ringing alarm bells about rising light pollution destroying pristine night skies. This time, though, their worries extend beyond their core discipline.

From black holes to the search for life, scientific breakthroughs are on the horizon as new observatories come online.

The James Webb Space Telescope has for the first time peered inside a planet-forming disk of dust surrounding a nearby star, a development promising to supercharge the search for exoplanets.

After years of conflict, a Hawaiian mountain that's home to some of the most important astronomical observatories on Earth finds itself at peace.

A star has survived a close encounter with a black hole, but the black hole has been able to sneak a second bite.

An international team of scientists has found a huge new alien world that's on the boundary between planet and "failed star."

Centuries after Chinese and Japanese astronomers spotted a bright light in their skies, astronomers have pinned it to a stellar collision that unleashed a rare supernova 850 years ago.

Fast radio bursts are still a mystery, but new observations of this strange phenomenon may actually help astronomers learn more about our own galactic neighborhood.

Three newly discovered ultra-faint dwarf galaxies could offer clues to the conditions in the early universe and to the nature of dark matter.

The latest image clicked by James Webb Space Telescope sheds light on how early stars formed during cosmic noon — more than 10 billion years ago.

Neutron-star mergers could create hypermassive neutron stars that are the fastest spinning stars in the universe.

Galaxies in the early universe were much more varied and mature than previously thought, according to observations made by NASA's James Webb Space Telescope.

You can help NASA discover new planets using your personal telescope or even just your smartphone.

With the James Webb Space Telescope safely at work, a leading scientist offers glimpses of what could come next.

NASA's latest flagship telescope is still in its first year of science, but the agency isn't only hard at work building its successor — it's starting to plan that next mission's successor as well.

NASA's James Webb Space Telescope has revealed dozens of galaxies that could be among the earliest known galaxies in the universe.

The historic James Webb Space Telescope has confirmed its first rocky exoplanet, 41 light-years from Earth.

A 'green pea' galaxy seen in an early James Webb Space Telescope image may be the most chemically primitive galaxy ever discovered.
