This pintsized powerhouse takes images of the night sky that will surprise even seasoned astrophotographers.

Observing obstacles plague all amateur astronomers, but when the chance arises, we can still embrace unanticipated wonder.

The fast spin of small near-Earth asteroids suggests scientists need to revise their ideas about what holds these rocky bodies together.

Astronomers have found that star-forming galaxies in the early universe were far messier than modern-day disk galaxies.

Albert H. Nagler, a pioneer of telescope optics, passed away at the office of his company Tele Vue Optics on Monday, October 27th. He was 90 years old.

In this month’s Sky Tour astronomy podcast, we’ll watch two sets of shooting stars, spot some bright planets, point out a few late-autumn constellations, and put a spotlight on five fascinating stars.

A new study has found that the 260-day ritual calendar is the key to understanding how the Maya predicted solar eclipses.

Saturn is in excellent view all evening. In a telescope its rings look like a thin needle piercing the big yellow globe. Soon the rings will turn exactly edge-on.

An alien comet will soon depart from the Sun's glare and enter the morning sky. Get ready for the observing opportunity of a lifetime.

Two recent discoveries of black hole mergers add to the evidence that such mergers happen over and over again.

Astronomers have discovered a ready-to-image super-Earth candidate less than 20 light-years away.

The merged remnants of stellar pairs may orbit the Milky Way’s central, supermassive black hole.

The crescent Moon returns and waxes to first quarter. Two binocular comets are on the way out. And Arcturus is once again the Ghost of Summer Suns.

The discovery of a new array of molecules spouted from Enceladus indicates new promise for habitability within Saturn's frozen-over ocean.

Astronomers have discovered a second asteroid in the inner solar system, circling the Sun almost entirely within the orbit of Venus.

In a surprise to researchers, the small, icy bodies beyond Pluto's orbit tend to rotate opposite the way they move around the Sun, which might say something about how they formed.

The longest-duration burst of gamma rays on record might mark the moment a black hole tunneled through a star and blew it up from within.

After checking out the two binocular comets right after dark this week, catch a double shadow transit on Jupiter and the late-night Orionid meteors.

Circumstances are ideal for watching debris from Halley's Comet set the morning sky ablaze.

Sky & Telescope’s 2025 “Galileo’s Italy” tour offered much more than sightseeing, as participants enjoyed multiple opportunities to stand on astronomical hallowed ground.

Precise measurements of stars’ motions show that a wave is propagating outward from our galaxy’s center — perhaps from a long-ago collision with another galaxy.
