ESA will open its doors to members of the public at its Earth Observation centre in Frascati, near Rome, Italy, on 29 September, as part of its annual open day.

We can’t understand nature without understanding its range. That’s apparent in exoplanet science and in our theories of planetary formation. Nature’s outliers and oddballs put pressure on our models and motivate sc...

Astronomers using simulated data have produced a glimpse of the sky as it would appear in gravitational waves, cosmic ripples in space-time generated by orbiting objects. The image shows how space-based gravitational wav...

Paleontologists have uncovered a new fossil in South America that belongs to a fearsome predator from the long-gone Permian Period.

AST Space Mobile said Sept. 19 its Blue Walker 3 test satellite that's been in orbit for a year recently relayed its first 5G phone call to an ordinary smartphone in a cellular dead zone. The post AST SpaceMobile's proto...

The four astronauts headed to the moon next year on the Artemis II mission suited up and took a practice run to the launch pad in the new crew transport vehicles at Kennedy Space Center on Wednesday.

Supermassive black holes are even more fearsome eaters than scientists suspected, thanks to a "delivery system" that could help them feed over months rather than hundreds of years.

NASA astronaut Frank Rubio spoke from the International Space Station on Sept. 19 just ahead of his record-breaking year in space mission date on Sept. 21. The Hispanic American told Space.com why role models are importa...

SAIC and LeoLabs have signed an agreement to jointly develop a space-tracking software platform. The post LeoLabs, SAIC to develop space-tracking software platform appeared first on SpaceNews.

Dark matter might have its own force, mediated by dark photons similar to the way electromagnetism is mediated by photons. A new study shows that not only are dark photons consistent with experiments in particle physics,...

Sierra Space's latest explosion with its LIFE module tested a metal plate inside an inflatable structure. The module will fly on a private successor to the International Space Station.

The sun-kissing spacecraft watched as dust particles were displaced across 6 million miles (9.7 million kilometers).

A new study recommends looking for Dyson Spheres that are smaller, orbit closer to their suns, and might still be under construction. The post We Should Be Looking for Small, Hot Dyson Spheres appeared first on Universe ...

The star T CrB flares up every 80 years. A document from 1217 could help confirm its regularity.

Planet Earth is about to receive a special delivery--the biggest sample yet from an asteroid.

A SpaceX launch from Cape Canaveral lit up the Space Coast for the 50th time this year while also achieving a milestone for the company.

A faint "bridge" of gas connects two colliding galaxies in a new photo from the Hubble Space Telescope.

On Earth, continents are likely necessary to support life. Continents "float" on top of the Earth's viscous mantle, and heat from the planet's core keeps the mantle from solidifying and locking the continents into place.

Purdue University scientist Briony Horgan is leading NASA's Mars rover into unfamiliar territory as the mission turns toward its next opportunity to find ancient signs of life on the red planet.

The first use of a novel method of analyzing Mars' gravitational force supports the idea that the planet once had an extensive northern ocean.

About three billion years ago, rushing water on Mars carried mud and boulders down a steep slope and deposited them into a vast fan-shaped debris pile. NASA’s Curiosity Rover has been trying to reach a ridge overlookin...

There may be less water ice trapped in the permanently shadowed regions on the moon than previously thought.
