Parker Solar Probe is alive and well after skimming by the Sun at just 15 million miles (24 million kilometers) from our star’s surface. This…
A billion light-years from Earth lies one of the universe’s most massive structures, a giant elliptical galaxy surrounded by a sprawling cluster of other galaxies…
NASA’s Mars Curiosity rover drove about 197 feet (60 meters) over the weekend to a site called Lake Orcadie, pushing its total odometry to over…
On October 7, 2018, an astronaut aboard the International Space Station (ISS) shot this photograph while orbiting at an altitude of more than 250 miles…
Early in the morning of November 7, 2018, NASA launches the Ionospheric Connection Explorer, or ICON, a spacecraft that will explore the dynamic region where…

This captivating image from the NASA/ESA Hubble Space Telescope’s Wide Field Camera 3 shows a lonely dwarf galaxy, a staggering 100 million light-years away from…
Stellar variability has long offered insights into stars’ physical properties. The star Mira (Omicron Ceti), for example, was so-named in 1596 by Dutch astronomers who…
ESA’s Gaia mission has made a major breakthrough in unraveling the formation history of the Milky Way. Instead of forming alone, our Galaxy merged with…
NASA’s Dawn spacecraft has gone silent, ending a historic mission that studied time capsules from the solar system’s earliest chapter. Dawn missed scheduled communications sessions…
This “super-resolution” view of asteroid Bennu was created using eight images obtained by NASA’s OSIRIS-REx spacecraft on October 29, 2018, from a distance of about…
Shadows on Earth can be mysterious and foreboding, but when they occur in space, they can convey information we otherwise could not know. In a…
Every Mars landing is a knuckle-whitening feat of engineering. But each attempt has its own quirks based on where a spacecraft is going and what…
