The Lucy spacecraft is heading to Jupiter's Trojan asteroids. But first it will rendezvous with the main-belt asteroid Donaldjohanson on April 20. The post Lucy spacecraft to fly by asteroid Donaldjohanson today. Expect surprises first appeared on EarthSky.

Nicknamed the "Big Wheel," a giant, spiral-shaped disk galaxy was spotted in an unusually crowded part of the early universe just two billion years after the big bang

Astronomers have spotted a cosmic anomaly: a huge, delicate spiral galaxy with massively powerful jets. What does this mean for our Milky Way galaxy? The post Cosmic anomaly hints at frightening future for Milky Way first appeared on EarthSky.

The wind on Saturn's largest moon is strong enough to blow around rocks of up to half a metre in diameter, which could put NASA's upcoming Dragonfly mission at risk

A star has been spotted shooting away from the heart of our galaxy at around 500 kilometres per second, giving astronomers clues about a group of stellar objects that are hard to observe directly

SIMP 0136 shows just how complex our universe really is.

Sagittarius A* has everything. Faint flickers, bright eruptions, and more.

A new image from ESO's Very Large Telescope provides what these astronomers called "our clearest view yet" of a filament in the cosmic web. The post A filament of the cosmic web! Clearest image yet first appeared on EarthSky.

A new image from the NASA/ESA Hubble Space Telescope shows two protostars in the Orion Nebula, a diffuse nebula located approximately 1,350 light-years away in the constellation of Orion.

The James Webb Space Telescope captured photos of one of the earliest supernovas ever seen using infrared technology, and creating a time lapse of the phenomena.

The cryovolcanic "centaur" comet 29P/Schwassmann-Wachmann has erupted four times in less than 48 hours, becoming unusually bright in the process. It is the most powerful outburst from the city-size oddball in more than three years.

A "once in a lifetime" comet is expected to light up the night sky as it passes by Earth.

A planet swings in front of its star, dimming the starlight we see. Events like these, called transits, provide us with bounties of information about exoplanets—planets around stars other than the sun. But predicting when these special events occur can be challenging…unless you have help from volunteers.

Scientists continue to learn new things about the planet, its sweeping rings and its many moons

At just 300 light-years apart, these are the nearest confirmed pair of supermassive black holes spotted in our local universe using visible and X-ray light observations. While...

The North Star's surface is surprisingly spotty, new high-definition observations of Polaris reveal.

To celebrate the 25th anniversary of its launch, NASA's Chandra X-ray Observatory is releasing 25 never-before-seen views of a wide range of cosmic

NASA's Webb space telescope has revealed that exoplanet LHS 1140 b is a super-Earth ocean world. It may have an ocean on one side or a global ice-covered ocean. The post Eyeball ocean world? Webb reveals an intriguing super-Earth first appeared on EarthSky.
