On August 12, 2023, NASA’s STEREO-A spacecraft passes between the sun and Earth, marking the first Earth flyby of the nearly 17-year-old mission. The visit home brings a special chance for the spacecraft to collaborate with NASA missions near Earth and reveal new insights into our closest star. The twin STEREO (Solar TErrestrial RElations Observatory) […]

The universe is humming with gravitational radiation—a very low-frequency rumble that rhythmically stretches and compresses spacetime and the matter embedded in it. That is the conclusion of several groups of researchers from around the world who simultaneously published a slew of journal articles in June describing more than 15 years of observations of millisecond pulsars

An 18-year-old Aberdeen University student and her mother will travel to space later this week after winning a place on Virgin Galactic’s second commercial flight in a prize draw. Anastatia Mayers and her mum Keisha Schahaff will be the first mother and daughter to go to space. The pair will take off from New Mexico

Scientists have made the most precise measurements ever of Mars’s rotation, for the first time detecting how the planet wobbles due to the “sloshing” of its molten metal core. The findings, detailed in a recent Nature paper, rely on data from NASA’s InSight Mars lander, which operated for four years before running out of power

The Euclid space telescope, launched July 1 on a mission to shed more light on elusive dark matter and dark energy, has reached its destination orbit and on Monday its European operators revealed its first test images. The star-filled snapshots were taken during the space telescope‘s commissioning—a phase during which its powerful instruments are finely

A new image of the galaxy cluster known as “El Gordo” is revealing distant and dusty objects never seen before, and providing a bounty of fresh science. The infrared image, taken by NASA’s James Webb Space Telescope, displays a variety of unusual, distorted background galaxies that were only hinted at in previous Hubble Space Telescope

Among the cargo headed to the International Space Station is an upgrade for NASA’s quantum physics facility, the Cold Atom Lab. A Northrop Grumman Cygnus resupply spacecraft is on its way to the International Space Station with more than 8,200 pounds of NASA science investigations and cargo after launching at 8:31 p.m. EDT Tuesday from

The first rocket launch from the surface of another planet will be accomplished using two solid rocket motors. NASA’s Mars Ascent Vehicle (MAV) recently reached some major milestones in support of the Mars Sample Return program. The Mars Ascent Vehicle would be the first launch of a rocket from the surface of another planet. The

The spinning, solar-powered spacecraft will take another look of the fiery Jovian moon on July 30. When NASA’s Juno mission flies by Jupiter’s fiery moon Io on Sunday, July 30, the spacecraft will be making its closest approach yet, coming within 13,700 miles (22,000 kilometers) of it. Data collected by the Italian-built JIRAM (Jovian InfraRed

By conducting radial velocity (RV) follow-up observations of the GJ 367 planetary system with the High Accuracy Radial velocity Planet Searcher (HARPS), an international team of astronomers has detected two additional alien worlds, at least four times as massive as the Earth. The finding was reported July 18 on the pre-print server arXiv. Located some
