Comet 12P/Pons-Brooks has awakened again from its recent slumbers with a fresh outburst. It's now bright enough to see in a modest telescope.

Discover the observations of astronomer Francis Baily as he watched sunlight bead along the lunar limb during an 1836 annular eclipse.

A partial/annular eclipse of the Sun washes across the Americas on Wednesday the 14th. Four days before, the waning Moon and Venus pair up in early dawn with Regulus glimmering between them.

A solar eclipse will soon grace the skies over the Americas. On Saturday, October 14, 2023, the Moon will cross in front of the Sun, spending up to 5 minutes 17 seconds centered on the brilliant solar disk, but it will cover at most 90% of it. The remaining 10% will appear as a blazing “ring of fire” around the Moon’s black silhouette.

Astronomers have directly imaged emission from the cosmic web, the filamentary structure that underlies the universe.

The October annular eclipse is coming up, and the most important requirement will be clear skies. Here's how to forecast the weather.

A new understanding of far-off worlds in the outer solar system suggests that if "Planet X" ever existed, it has long since left the vicinity.

Get acquainted with Comet 103P/Hartley. It's been a dozen years since its last bright apparition. While you're at it challenge yourself to spot the elusive gegenschein.

The bright BlueWalker 3 satellite, a prototype for the even larger Bluebird satellites, is one of the brightest objects in the sky.

After decades of searching, scientists have found stars accompanying the gas streaming from two smaller galaxies that orbit our Milky Way.

This month’s big celestial news might be the annular solar eclipse that will be seen in the Americas, but everyone can share the fun of casual stargazing by streaming or downloading October’s Sky Tour astronomy podcast.

The Moon pairs with Jupiter, then the Pleiades, as it departs the evening sky. That leaves a dark-sky Milky Way crossing the zenith, where Cygnus the Milky Way Swan flies southward for fall.

Astronomers have discovered two Neptune-size planets that are denser than rock and in searingly close orbits to their star. How did these odd worlds form?

The week of September’s new Moon, a passel of astro-enthused passengers joined us to explore one of the world’s premier observing locations.

NASA’s newest mission is bound for the metallic asteroid of the same name. The metal-rich rock offers us a view of asteroid interiors.

As hundreds of astronomers made their annual pilgrimage to the “shrine to the stars” this year, the Springfield Telescope Makers were preparing to celebrate Stellafane's 100th anniversary.

Samples taken from the asteroid Bennu are now safely on Earth.

Data coming from the Webb and Hubble space telescopes suggests two exoplanets might be water worlds. But the evidence isn’t yet definitive.

The bright Moon steps east night by night under Altair, then Saturn, then the Great Square of Pegasus. Meanwhile, Deneb replaces Vega as the zenith star; welcome to fall.

The Earth's atmosphere and the large size of the solar disk result in unequal days and nights, even on the equinox.

Some eclipse-chasers may choose to view a “broken ring” on October 14, 2023, in exchange for the chance to see something even more spectacular: Baily's Beads
