Planetary construction sites around other stars are filled with pebbles, and for the first time radio telescopes have detected these tiny chunks of rock that stick together to form planets.

With the universe constantly expanding, scientists have a hard time finding where its center is.

"It is incredible that modern telescopic surveys have the ability to detect such small objects up to millions of kilometers away."

"Can humanity enjoy the benefits of both asteroid and lunar mining without compromise, or do we have to choose one at the expense of the other?"

Astrophotographer Philippe Tosi captured explosive Ellerman bombs on the sun's surface as an active sunspot turned toward Earth.

Earth may be safe from an impact by the asteroid 2024 YR4, but it still has a chance of striking the moon. This lunar impact could pose a risk to space tech and astronauts.

3I/ATLAS isn't just fascinating because it is the third interstellar visitor found in the solar system; new research suggests it's also the oldest comet ever seen, at over 7 billion years old.

The James Webb Space Telescope (JWST) is celebrating three years of transformational science with a striking new image of the Cat's Paw Nebula.

Using the James Webb Space Telescope, astronomers have probed the dusty shells that surround dying stars called Wolf-Rayet stars.

The scientific and cultural impact of 3I/ATLAS over the coming months and years will serve as an exemplar of what astronomy can learn and why it matters.
