NASA’s Europa Clipper has embarked on its long voyage to Jupiter, where it will investigate Europa, a moon with an enormous subsurface ocean that may have conditions to support life.
A new NASA-led study suggests that a potential exomoon may be orbiting the exoplanet WASP-49 b, a gas giant located 635 light-years from Earth. The possible exomoon is believed to be rocky and volcanically active, similar to Jupiter's Io.
A solar sail is designed to capture the tiny amounts of radiation pressure exerted by sunlight to propel a spacecraft to incredible speeds.
An international team of scientists has successfully measured a planet-wide electric field thought to be as fundamental to Earth as its gravity and magnetic fields.
Nasa has announced the first detection of possible biosignatures in a rock on the surface of Mars.
Our CO2 emissions are warming the planet and making life uncomfortable and even unbearable in some regions.
To celebrate the 25th anniversary of its launch, NASA’s Chandra X-ray Observatory is releasing 25 never-before-seen views of a wide range of cosmic objects.
July 22, 2024, was the hottest day on record, according to a NASA analysis of global daily temperature data. July 21 and 23 of this year also exceeded the previous daily record, set in July 2023.
Neutron stars are some of the most extreme objects in the universe. Formed from the collapsed cores of supergiant stars, they weigh more than our Sun and yet are compressed into a sphere the size of a city.
NASA's Global-scale Observations of the Limb and Disk (GOLD) mission has revealed unexpected C- and X-shaped formations in an electrified layer of gas high above our heads called the ionosphere.
In a contract worth up to US$843 million, NASA has selected SpaceX to design the "US Deorbit Vehicle." The spacecraft will bring the $150 billion International Space Station out of orbit to safely and burn up in our atmosphere.
The analysis is key to confirming carbon and nitrogen-rich dusts and organic compounds essential for life. However, the sample also revealed the presence of magnesium-sodium phosphate, which had not been detected before.
NASA has new plans to launch a tiny satellite mimicking a star into space.
After months of driving, Perseverance has finally arrived at "Bright Angel", discovering oddly textured rock unlike any the rover has seen before.
NASA’s Voyager 1 spacecraft is conducting normal science operations for the first time following a technical issue that arose in November 2023.
