A cosmic lens magnified the light of an exploding star. Now, astronomers are using observations of that supernova to calculate the universe’s current rate of expansion.

As Venus and Mars move toward each other in the western dusk, Venus brightens and Mars shrinks. Just like they always do. This week the Moon hops over both.

An unusual streak of stars thought to have formed in the wake of a wandering supermassive black hole might just be a spiral galaxy seen edge-on.

I traveled to Lake Turkana in Kenya in 2013 to observe just 11 seconds of totality during a hybrid solar eclipse. During this uncommon event, the apparent diameters of the […]

NASA spacecraft are constantly sending back images from across the solar system. Here are two that caught our eye.

The May 17th dawn pairing of Jupiter and the Moon may be one of the most amazing conjunctions you'll ever see.

Get ready for the Grand Canyon Star Party on June 10–17, 2023.

A rock that crashed through the roof of a house in New Jersey proved to be the real thing — a chunk spalled from a 4.5 billion-year-old asteroid.

New JWST images reveal that one of the most distant objects ever observed is actually two baby galaxies on a possible collision course.

James Webb Space Telescope observations offer a new window inside the atmosphere of the secretive sub-Neptune GJ 1214b.

The Minor Planet Center is announcing a bevy of new moons for Saturn that will bring its total to 145 (and break Jupiter's record).

Mars and Venus each line up with a pair of stars this week. And with the Milky Way lying all around the horizon, the Coma Berenices Star Cluster floats overhead.

When you want to relax under the stars there's no better way than on your back looking up at the zenith. We explore what's overhead and discover there's more than one zenith up there.

Surprising new results from the United Arab Emirates' Hope probe call the origin of Mars's smaller moon into question.

Continuing its run of ground-breaking discoveries, the James Webb Space Telescope has snapped the clearest images yet of the dusty disk around the young star Fomalhaut.

There's a second ring around the far-out dwarf planet Quaoar, adding to the mystery of how this world hosts rings at such wide orbits.

Four of Uranus's five icy moons likely contain a thin layer of briny (or otherwise enriched) water, astronomers have concluded from Voyager 2 data.

The first stars are too faint and far away to detect directly, but their gaseous remains can be seen absorbing the light of distant galaxies.

Big, macho Venus is closing in on wimpy little Mars in the western sky at dusk. Venus says hi to M35 on the way. In early dawn, the waning Moon guides the way to Saturn.

The Sun has recently experienced an uptick in activity, with lots of sunspots accompanied by flares, coronal mass ejections, and visible auroras — but experts still expect a mild solar cycle.

For the first time, astronomers have witnessed a star eat an exoplanet.
