Dark matter may scatter against each other only when they hit the right energy, say researchers in Japan, Germany, and Austria in a new study….
Three images from NASA’s Spitzer Space Telescope show pairs of galaxies on the cusp of cosmic consolidations. Though the galaxies appear separate now, gravity is…
Every object, planet, or person traveling through space has to contend with the Sun’s damaging radiation — and the Moon has the scars to prove…
NASA invites you to take a behind-the-scenes look at how the agency explores Earth and outer space with a new monthly television series that premieres…
Globular clusters like NGC 2419, visible in this image taken with the NASA/ESA Hubble Space Telescope, are not only beautiful but also fascinating. They are…
Astronomers using the NASA/ESA Hubble Space Telescope, along with older data from the Voyager 2 probe, have revealed more about the origin of Neptune’s smallest…
Dramatic atmospheric features in Jupiter’s northern hemisphere are captured in this view from NASA’s Juno spacecraft. The new perspective shows swirling clouds that surround a…
The mission team called it a “stretch goal” – just before closest approach, precisely pointing the cameras on NASA’s New Horizons spacecraft to snap the…
The last screw is tightened and a private Moon lander is packed in the fairing atop a SpaceX Falcon 9 rocket at Cape Canaveral Air…
Scientists have discovered tadpole-shaped jets coming out of regions with intense magnetic fields on the Sun. Unlike those living on Earth, these “tadpoles” — formally…
A compilation of scientific results from The Stratospheric Observatory for Infrared Astronomy, SOFIA, reveals new clues to how stars form and galaxies evolve, and are…
Astronomers call it “the moon that shouldn’t be there.” After several years of analysis, a team of planetary scientists using NASA’s Hubble Space Telescope has,…
Astronomy & Astrophysics published the work of researchers from the University of Vienna, who have found a river of stars, a stellar stream in astronomical…
TRAPPIST-1 is a system of seven Earth-sized worlds orbiting an ultra-cool dwarf star about 120 light-years away. The star, and hence its system of planets,…
Since Pluto’s demotion from a fully-fledged planet to a dwarf planet, Neptune holds the title of the outermost planet in the Solar System. This new…
New results from NASA’s Chandra X-ray Observatory may have helped solve the Universe’s “missing mass” problem. Astronomers cannot account for about a third of the…
In this image, the NASA/ESA Hubble Space Telescope has captured the smoking gun of a newborn star, the Herbig–Haro objects numbered 7 to 11 (HH…
