Research results in astronomy, solar physics, and planetary science are about to become more widely accessible to scientists and the public alike. The American Astronomical Society (AAS) today announced the switch of the Society’s prestigious journals to fully open access as of 1 January 2022.
The calendar might say “September,” but now is the perfect time to explore the Summer Triangle. Find your way with this month's Sky Tour podcast.
Gamma Cassiopeia may lack a proper name, but the middle star of the "W"-shape constellation is worth finding on the sky.
Shoemaker discovered more than 800 asteroids and 32 comets, including one of the most famous comets of the 20th century.
A pair of spacecraft will head to Mars in 2024 as the ESCAPADE mission, to study the Martian space weather environment.
Venus, Jupiter, and Saturn are all getting a little higher in early evening. Vega passes the zenith soon after dark; Deneb does so two hours later. Andromeda is up in the east.
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.
