NASA's Transiting Exoplanet Survey Satellite space telescope has now wrapped up the primary phase of its mission, completing an extensive survey of the starry sky that revealed 66 new exoplanets and thousands more candidates.

New analysis of data collected during NASA's Dawn mission has offered some compelling answers to long-standing questions about the makeup of Ceres, starting with presence of a 25-mile-deep reservoir of brine beneath the dwarf planet's surface.

A NASA spacecraft has observed a pulsing glow coming from Mars. Huge spots of ultraviolet light were seen in the night sky, pulsing with uncanny regularity – exactly three times every night. The find highlights the Red Planet's atmospheric processes.

Balloons may seem outdated, but for high-flying scientific instruments they’re making a comeback. NASA has now unveiled ASTHROS, a new infrared telescope that will be carried to the edge of space by a balloon the size of a football stadium.

History was made today as two NASA astronauts returned to Earth from the International Space Station (ISS) aboard the privately built and operated SpaceX Crew Dragon Endeavour capsule. It was the first manned splashdown since July 25, 1975.

NASA has announced that, soon after yesterday’s launch of the Mars Perseverance rover, that mission had experienced minor issues that hindered communication and caused the spacecraft couriering the rover to enter a "safe mode."

NASA's Mars 2020 mission and the Perseverance rover are on their way to Mars. At 4:50 am EDT (11:50 GMT), the spacecraft lifted off on the first leg of its 309-million-mile voyage to search for signs of life on the Red Planet.

When NASA’s Perseverance rover touches down on Mars it will carry with it the first ever spacesuit samples to land on the Red Planet. The samples will be exposed to the high-radiation environment to test the durability of future spacesuits.

When NASA's Perseverance Mars rover touches down on the Red Planet on February 18, 2021, its descent stage will guide it autonomously to a (hopefully) safe landing thanks to a pair of the most precise Martian maps ever produced.

NASA has released the first images taken by its Juno deep-space probe of the north pole of Jupiter's largest moon, Ganymede, which reveal that the Ganymedean polar region contains a glass-like form of ice formed by bombardment of solar particles.

NASA and ESA have announced that the launch of the James Webb Space Telescope has been delayed to October 2021. A recently-completed schedule risk assessment recommended the delay, due to challenges raised by the ongoing COVID-19 pandemic.

An ESA/NASA spacecraft has captured the closest pictures of the Sun ever taken. The images reveal that our star is covered in relatively tiny flare-like explosions that scientists have dubbed "campfires."
