When the Sun rages and storms in Earth's direction, it changes our planet's atmosphere. The atmosphere puffs up, meaning satellites in Low-Earth Orbit (LEO) meet more resistance. This resistance... creates orbital decay, dragging satellites to lower altitudes. One researcher says we can change the design of satellites to decrease their susceptibility.

NASA and Axiom Space are indefinitely delaying a private astronaut mission to the International Space Station because of an air leak in a Russian module. The post NASA indefinitely delays private... astronaut mission, citing air leak in Russian module appeared first on SpaceNews.

Most scientists agree that supernova explosions have affected Earth's climate, though the details are not all clear. They likely cooled the climate several times in the last several thousand years,... just as humanity was becoming established around the world. The evidence is in telescopes and tree rings.

Astronomers have used JWST to study a fascinating planetary system that's only 16.7 million years old, with two bizarre giant exoplanets. Designated YSES-1, its closer planet, YSES-1b seems to be... surrounded by a disk of material that could be the birthplace of moons, similar to what might have happened at Jupiter billions of years ago. The other, YSES-1c, has a layer of silicate particles in its upper atmosphere--clouds of sand.

Astronomers have discovered a "teenage vampire" dead star in the process of devouring a companion star during a short-lived, "missing link" phase of its evolution.

Learn more about a newly discovered dinosaur species that is now the closest-known ancestor to the Tyrannosaurs.

Simultaneously cooling Pluto while energizing atmospheric molecules to allow them to escape into space, Pluto's haze plays a key role in the planet's energy balance.

Astronomers have discovered a "jellyfish" galaxy whose unusual shape and internal mechanisms--including distinctive "bunny ears" and an inner "tail"--are giving researchers an unprecedented view of... dynamics within one of the universe's most extreme environments.

NASA's SLS (Space Launch System) solid rocket boosters are the largest, most powerful solid propellant boosters to ever fly. Standing 17 stories tall and burning approximately six tons of propellant... every second, each booster generates 3.6 million pounds of a thrust for a total of 7.2 million pounds: more thrust than 14 four-engine jumbo commercial […]

The European Space Agency (ESA) said Thursday it was looking to bolster alliances with countries other than the United States as it adapts to looming cuts at key partner NASA.

The time-lapse footage was captured by NASA astronaut Jonny Kim.

One of the coolest designs of any star projector we've seen, we think the Dinosaur Egg Galaxy Star Projector is amongst the best options for kids.

A chartered spaceflight for India, Poland and Hungary's first astronauts in decades has been delayed indefinitely because of leak concerns at the International Space Station.

Pismis 24, the star cluster seen here in an image released on Dec. 11, 2006, lies within the much larger emission nebula called NGC 6357, located about 8,000 light-years from Earth. The brightest... object in the picture was once thought to be a single star with an incredibly large mass of 200 to 300 solar […]

The Atacama Large Millimeter/submillimeter Array (ALMA) has uncovered a key piece of the puzzle in how rocky planets, such as Earth, form around young stars. For decades, scientists have struggled to... explain how dust grains in the disks around newborn stars grow from tiny dust grains to planet-building "pebbles" without either spiraling into the star or shattering in collisions--a challenge known as the "meter-size barrier."

Combining the way that massive galaxies and galaxy clusters bend space and magnify our view of the distant universe with powerful new instruments sensitive to gravitational waves and electromagnetic... radiation will lead to scientific breakthroughs in fundamental physics, cosmology, and astrophysics, a new study reveals.

With hurricane season underway, NASA is gearing up to produce cutting-edge research to bolster the nation's readiness and response to severe weather.

Dark matter affects how stars move within galaxies, how galaxies build up over time, and how everything in the universe is held together--but no existing tool has directly detected it. While dark... matter does not reflect, absorb, or emit light, it can still be indirectly observed by telescopes.

Proof-of-concept results from the mouth of the Tijuana River in San Diego County show how an instrument called EMIT could aid wastewater detection. An instrument built at NASA's Jet Propulsion... Laboratory  to map minerals on Earth is now revealing clues about water quality. A recent study found that EMIT (Earth Surface Mineral Dust Source Investigation) […]

A new generation of aerospace explorers will soon embark on a hands-on summer experience focusing on careers in science, mathematics, engineering, and technology (STEM). This month, NASA's Armstrong... Flight Research Center in Edwards, California, and the Flight Test Museum Foundation will launch the 2025 Junior Test Pilot School. Held at Blackbird Airpark and Joe Davies […]

NASA is launching rockets from a remote Pacific island to study mysterious, high-altitude cloud-like structures that can disrupt critical communication systems. The mission, called Sporadic-E... ElectroDynamics, or SEED, opens its three-week launch window from Kwajalein Atoll in the Marshall Islands on Friday, June 13.

The Unistellar eQuinox 2 is our telescope experts' pick as the best overall smart telescope, and is now $420 off for Father's Day.

Big franchises like 'Star Wars' and 'The Fantastic Four' are joined by exciting original works. These are the sci-fi comics we can't wait for in 2025.

At least three ESA space missions are under threat as a result of Trump's budget cuts. The gravitational wave observatory LISA, Venus orbiter EnVision, and NewAthena may require "recovery actions."
