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, dr...

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, citin...

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 b...

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...

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 bo...

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.

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 wa...

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 gra...

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,...

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 mineral...

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 Cente...

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, op...

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.
