Journey to a remote planet then double back to check in on the latest stirrings of Comet 29P/Schwassmann-Wachmann before touching the finger of dawn.

A new study uses precise measurements of chemical elements to explore the formation history of one of the oldest globular clusters in the Milky Way.

Astronomers witness the unfurling of a black hole-powered mushroom cloud, a baby super-Jupiter, and a magnetic "tunnel" around the solar system.

Astronomers, dark-sky advocates, and satellite operators are discussing light pollution and satellite constellations with the United Nations' Office of Outer Space Affairs.

As fall proceeds, Jupiter and Saturn shift westward and tilt ever more steeply. Venus gets a little higher and brighter. The waning Moon passes the Pleiades. And as Halloween approaches, Arcturus becomes the Ghost of Summer Suns.

The largest haul of fast radio burst observations ever recorded, all from a single fast radio burst, is helping astronomers understand what causes these fleeting cosmic phenomena

The COSI mission will study the recent history of star birth, star death, and the formation of chemical elements in the Milky Way.

Follow these tips to help capture auroral displays.

A group of Japanese astronomers just discovered a potential new impact at the planet Jupiter.

NASA’s ambitious Lucy mission has launched to explore Jupiter's Trojan asteroids, pristine examples of the solar system's early years.

Join fellow lunar enthusiasts all over the world in celebrating the Moon this weekend.

The gibbous Moon shines under Jupiter and Saturn, then waxes to full under the Great Square of Pegasus. Cassiopeia stands on end high in the northeast, as Capella glitters far below.

The Moon may have formed in a one-two punch, new simulations suggest.

We examine circumstances and expectations for the current apparition of Comet Leonard, which may become the year's brightest comet.

The city's parks, facilities, and streetlights will all get dark-sky-friendly lighting, but is it too early for amateur astronomers to get excited?

New Horizons has spotted two asteroid pairs in the outer solar system. Their existence sheds light on how planets formed.

Saturday, October 9, 2021, is this fall’s Astronomy Day!

The crescent Moon returns to the evening sky, passing Venus, then the Saturn and Jupiter pair. Venus itself passes Delta Sco and then Antares. Auroras may shimmer, the Draconids may sputter; the sky never ceases to call.

China's Chang'e 5 mission returned pieces of the Moon in a technological feat last year. Now, scientists are publishing the first analyses of those samples.

What seemed a lucky break — the discovery of a gamma-ray burst in the most distant known galaxy — might instead be the flash of passing space debris. As satellites fill low-Earth orbit, such events might become common.

Careful study of data from the New Horizons mission indicates that an iconic, caldera-looking feature isn’t an eruption site.
