After two years apart, amateur astronomers and telescope makers from around the country met at the top of Breezy Hill to enjoy the stars with old and new friends.

Strange behavior caught by two radio observatories may send theorists back to the drawing board.

Newly discovered asteroid 2021 PH27 orbits the Sun in just 113 days.

Watch black holes grow and galaxies fall — astro photos and visualizations to get you through the week.

Calling all amateur astronomers: NASA’s Night Sky Network wants to hear from you!

A geologically recent landslide on Mars appears like mudslides on Earth — but it would have required water during a time when Mars was expected to be dry.

Jupiter is at opposition on August 19th. If we take the long view — 12 years long — we can watch Jupiter's oppositions as it passes through the zodiac constellations.

Jupiter ands Saturn are just past opposition, so they dominate the sky all night. They inhabit dim Capricornus, which pushes Sagittarius westward. Venus, even showier, owns the western twilight but sets by full darkness.

Scientists found a strange little volcanic feature on the edge of a Venusian corona, giving further credence to the theory that the planet has a thin outer layer and an active interior.

Four concepts are competing to be NASA’s next flagship mission. From exo-Earths to X-rays, what will the future hold?

If skies are clear this weekend, we’ll see the full Moon. And not just any old full Moon, but the Blue Moon — the “true” Blue Moon.

If skies are clear this weekend, you'll see the full Moon. And not just any old full Moon, but the Blue Moon . . . the "true" Blue Moon!

Jupiter comes to opposition on August 20th, when it will shine brighter and closer than at any other time this year. With nights starting earlier and cooler temperatures arriving, there's no better time to make the most of the planet.

New research reveals that Saturn, like Jupiter, has a “fuzzy” core that extends 60% of the way to its surface, a finding that is changing how astronomers think about giant planets.

A new study suggests that wind, not water, created the rock layers in Gale Crater, where the Curiosity rover roams.

While many astrophotographers follow the "rule of 500" (or 300), some experimentation can help find the right exposure time for your setup.

No one knows why quasars flicker — but astronomers are using these wavering beacons to "weigh" the black holes that power them.

The Moon waxes from first quarter to gibbous in the evening sky, offering some of its most interesting telescopic aspects. Venus grows more insistent in the western twilight. And Jupiter and especially Saturn pose well in the southeast to south by late evening.

Perseverance came up empty on its first attempt to grab and stow a sample of Mars.

Careful measurements using the OSIRIS-REX spacecraft have refined astronomers’ predictions for how likely it is that this potentially hazardous asteroid will strike Earth.
