Venus almost meets Mars in the western twilight, then runs away. Vega and Arcturus become equally balanced across the zenith. Down from Vega hangs the Summer Triangle.

New results from the James Webb Space Telescope find that radiation from ordinary galaxies cleared the primordial haze left over from the Big Bang, allowing the first light to shine through the early universe.

Despite being four times larger than the original Starlink satellites, the new "Mini" version is fainter — as dim as astronomers have recommended such satellites be.

The Mercury-bound BepiColombo Mission made its third flyby past the solar system’s innermost world on June 19th.

Astronomers have found supermassive black holes in smaller galaxies are actually more likely to light up when they’re isolated in vast, cosmic voids.

Scientists detected phosphorous in an extraterrestrial ocean for the first time when they analyzed data from Saturn's moon Enceladus.

Astronomers have long suspected that the distant galaxy OJ 287 harbors not one but two supermassive black holes in its core — one with the mass of a whopping 18 […]

Venus and Mars are getting closer together in the western dusk. And why does Mars always turn so puny when it approaches Venus? The "Betelgeuse of Summer" is up, and the Little Dipper stands on end.

Smoke from Canadian wildfires has made observing the night sky a challenge for many. Here are some ways you can make the best of a bad situation.

The Sun flings charged particles and accompanying magnetic fields into the solar system, but how? NASA's Parker Solar Probe dives in to find out.

Supermassive stars might explain the unusual amounts of nitrogen in one of the most distant known galaxies, GN-z11.

A new study making the rounds predicts that supergiant Betelgeuse will explode as a supernova sooner rather than later, but others are urging caution.

Planetary exploration can take up a large portion of one’s life.

Now it's Venus's turn to pass the Beehive, with Leo looming over. The Summer Triangle lofts high. And the supernova in M101, near the Big Dipper, remains 11th magnitude.

The October 2023 and April 2024 solar eclipses will thrill millions of North Americans. These maps will enlighten and inspire viewers for the events to come.

Owen Jay Gingerich, well-known historian of astronomy and contributor to Sky & Telescope for more than half a century, died on May 28, 2023.

In the JWST version of the Hubble Deep Field, astronomers are discovering what galactic life was like in the earliest years of the universe.

Massive, dying stars — behemoths tens of times the Sun's mass — should emit gravitational waves that we can hear with LIGO.

After a year's delay, NASA's Psyche mission to the metal-rich asteroid of the same name is on track for a launch in October 2023.

When visual astronomy isn't possible — or even when it is — robotic telescopes can make way for more stargazing.

Venus shining in the dusk says goodbye to Pollux, hello to Mars. . . which is busy crossing the Beehive Cluster. Arcturus stands straight over Spica after dark, and Kochab stands straight over Polaris, it's that time of year.
