Lockheed Martin is joining in the effort to support a sea-based approach for launching Firefly Aerospace’s Alpha rocket. The 29.48-meter-tall (96.7 ft) rocket currently only launches from Space Launch Complex 2 at Vandenberg Space Force Base in California.
In conversation with Space.com, the new Planetary Society CEO talked about the fight to restore NASA's funding again 2027.
Astronomers using the James Webb Space Telescope have directly analyzed the surface of a distant super-Earth, revealing a dark, airless, Mercury-like world.
Watch Eta Aquarid meteors streak across the sky live from observatories and sky cams around the world.
Does the cancellation of 'Starfleet Academy' suggest that lean times are ahead for 'Star Trek' and 'Star Wars'?
Io is a world of extremes. It is by far the most volcanically active world in our solar system. Being continually squeezed in the never-ending tug-of-war between Jupiter and its larger satellites will do that to a moon. As a result, Io has over 400 “paterae” - volcanic depressions that spew lava up onto its surface. And, according to a new paper available in pre-print on arXiv and utilizing data from Juno’s Jupiter InfraRed Auroral Mapper (JIRAM) tool, we have been massively underestimating the power output of those paterae for decades.
A bright waning gibbous moon may wash out this week's Eta Aquarid meteor shower peak — but early risers could still catch a few shooting stars.
The concept of a spacetime manifold serves as the foundational geometric model for the universe in modern physics. It is a four-dimensional coordinate system that intrinsically links the three dimensions of space with the single dimension of time. This union allows for a comprehensive description of all events and physical phenomena.
Observations — including from an amateur astronomer — show that the Plutino 2002 XV93 has a thin wisp of air around it.
The Vela Supercluster, in our Milky Way's Zone of Avoidance, is competing gravitationally with other superclusters for the attention of local galaxies.
Looking like a scene out of "Star Wars," this image shows the ESO's Very Large Telescope Interferometer (VLTI) beaming four separate lasers into the sky towards the Tarantula Nebula.
The Eta Aquarid meteor shower peaks this week, but will you be able to see it?
Star Wars superfan and YouTube sensation Zach King recreates the seminal 1977 sci-fi film using cardboard.
From Japan to Turkey, celebrate Star Wars Day with this global collection of original trilogy posters.
Early galaxies were star-forming machines, gobbling up gas and spitting out stars with a furious intensity. A new model helps explain why things were so different back then.
Thirteen European satellites on the same rideshare launcher have successfully reached orbit, bringing capabilities to Italian and Greek monitoring programmes as well as CubeSats that will test satellite connectivity.
The exoplanet census continues to grow at a prodigious rate, with 6,273 confirmed planets to date and close to 20,000 candidates awaiting confirmation. What's more, the rate of discovery is accelerating, having passed 5,000 in early 2023 and 6,000 in September 2025. With such a large exoplanet census, along with improvements in instrumentation and data analysis, scientists are now focused on "exoplanet characterization" in addition to discovery. As always, the goal is to find planets that could be habitable for life as we know it (or "Earth-like").
NASA astronaut Chris Williams photographed a fireball from above recently, capturing the stunning site from aboard the International Space Station.
The human heart shrivels away in space, but researchers have found that mini-hearts grown from human stem cells sprout in space significantly faster than in labs on Earth.
Lego's larger Yoda models do not have a great track record, but this Lego Star Wars Yoda bust is such astonishing spectacle I have to own it. Or several.
From chasing the Milky Way to using your eyes as nature intended, here are some often-overlooked truths that make all the difference under the night sky.
