Deep-sky objects may appear static throughout our lifetime but by carefully "blinking" archival and current images we can discern real changes in their appearance.

Satellites’ leakage radiation, now detected for the first time, may become a major problem for radio astronomy, as “megaconstellations” keep on growing.

Mars meets Regulus while Venus looks on. Scorpius comes to its July height — bearing its double stars, Cat's Eyes, and Little Cat's Eyes. And keep a lookout for noctilucent clouds at the end of dusk.

The intrepid infrared explorer is offering astronomers a jump back in time, enabling them to see quasars at earlier times than ever before.

The James Webb Space Telescope offers a new view of Saturn, while the IceCube Observatory creates a neutrino-painted picture of the Milky Way.

Fighting light pollution, one mini star party at a time.

The European Space Agency’s New Space Telescope promises to unlock a key mystery of modern cosmology.

Count on our monthly Sky Tour podcast to help you get the most out your casual stargazing. It’s a fun and informative way to introduce yourself to the nighttime sky!

A glowing molecular cloud shines today because of a 200-year-old flare let out by our galaxy’s supermassive black hole, scientists say.

Full Moon in the Teapot. Are the colors of brights easier to discern in moonlight? Twilight? Mars closes in on Regulus as Venus watches. And the supernova in the Pinwheel Galaxy is still 12th magnitude.

Parker Solar Probe data offers new insight on the puzzle of how debris from an asteroid produces one of the brightest annual meteor showers.

Radio observatories across the globe have found compelling evidence for the existence of very-low-frequency gravitational waves.

Mergers between the Milky Way and long-ago dwarf galaxies have enriched our skies with dozens of iconic globular clusters. Many are visible in small telescopes.

Astronomers have discovered Jupiter's younger sibling in a system 88 light-years away. Meanwhile, only 40 light-years away, a Venus-size world turns out to be airless (or nearly so).

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 […]
