Smaller bodies of rock, metal, ice, and dust can be found scattered throughout space. These objects travel on their own courses, sometimes silently beyond Jupiter and occasionally quite close to Earth ...

For nearly three decades, astronomers tracked a 1,250-foot-wide object relatively close to Earth that they thought was an asteroid. It looked like one. It followed the expected path. Telescopes saw no ...

Observations with the instrument SPHERE at ESO's Very Large Telescope have produced an unprecedented gallery of "debris disks" in exoplanetary systems. Gaël Chauvin (Max Planck Institute for Astronomy ...

Comets around a young Sun-like star could reveal how water is transported into the inner regions of developing planetary ...

Learn about an object in space that has emerged as a dark comet, displaying a much fainter glow than most comets. Some near-Earth objects orbiting in space have a serious identity crisis. They may ...

Across the Earth, every night, thousands of automated stargazers are waiting to take pictures of shooting stars. I am one of the scientists who study these meteors. Most movies and news alerts focus ...

Astronomer Patrick M. Shober found a new meteor shower—and it comes from an asteroid getting broken down by the Sun. Reading time 4 minutes Across the Earth, every night, thousands of automated ...

For almost a decade—ever since 2017, when our first known interstellar visitor, 1I/‘Oumuamua, swooped through the inner solar system—astronomers have been grappling with a small but stubborn mystery.

Astronomers at Lund University in Sweden have found evidence of exocomets—comets in other solar systems—orbiting a young star ...
