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.

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

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.
