Astronauts aboard the International Space Station collect blood samples as part of a project to study human health in space.
Astronomers have discovered a baby exoplanet "spiral architect" carving complex swirls into a disk of gas and dust around the young star HD 135344B.
Our planet has been rotating at its fastest since records began in 1973.
South Korea just laid out its long-term space exploration road map, which features the planned construction of a moon base two decades from now.
Scientists have grown algae in bioplastic habitats under Mars-like conditions, a step that could bring long-term space colonization closer to reality.
Find the locations of the five landing zones considered as the setting for humanity's first steps on another world.
Supernovas, kilonovas, gamma-ray bursts... oh my! The Nancy Grace Roman Space Telescope will uncover 100,000 of these explosions and many more powerful and violent cosmic events.
The moon's crescent limb will cloak and uncover stars from the iconic cluster before sunrise.
On Episode 169 of This Week In Space, Rod Pyle and Tariq Malik are joined by JPL Chief Engineer Emeritus Rob Manning to look back at the Mariner 4 Mars mission 60 years later.
From "Star Wars" film sets to baboons in Saudi Arabia, here's how to experience the "eclipse of the century" in style on Aug. 2, 2027.
Blue Origin's powerful New Glenn rocket now has a payload for its second-ever flight —NASA's ESCAPADE Mars mission.
The new TRACERS mission will track magnetic reconnection that drives particles down into Earth's atmosphere when space weather turns bad.
A SpaceX Falcon 9 rocket carrying 24 Starlink satellites launched from Vandenberg Space Force Base in California on Friday, July 18, 2025.
Astronomers have discovered an object at the edge of the solar system that is locked in a strange rhythmic dance with the ice giant Neptune.
Stars of all ages and masses emit electromagnetic energy in different ways, and these emissions attract the attention of astronomers. Each of these emissions is a clue to how stars form, evolve, and even die. Young stars are known for their high luminosity and their high level of activity. They have strong stellar winds and powerful magnetic fields.
One of the world’s most powerful instruments reveals interstellar comet 3I/ATLAS as it heads towards perihelion.
Our understanding of the Universe begins with the Big Bang, a moment in time where the Universe began expanding into what we see around us now. Big Bang nucleosynthesis describes how only the lightest elements were created originally: hydrogen, helium, and a tiny bit of lithium. For elements heavier than those, which astrophysicists call metals, a generation of stars had to live and die.
Multiple space agencies plan to return astronauts to the Moon by the end of this decade. Along with commercial and international partners, these efforts aim to create infrastructure that will ensure a "sustained program of lunar exploration and development." This includes NASA's Artemis Program, China's International Lunar Research Station (ILRS), and the ESA's Moon Village, all of which consist of creating lunar habitats around the South Pole-Aitken Basin. Providing power for these bases is a significant challenge given the cycle of lunar day and night, which lasts for two weeks at a time.
Two teams of astronomers have simultaneously discovered a strange, spinning dead star that seems to defy our current understanding of both neutron stars and white dwarfs.
