American Astronomical Society Meetings: Latest discoveries and science

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.
