United Launch Alliance has closed its Delta rocket assembly line in Alabama, after the 389th and last Delta rocket rolled out of the factory for the journey to its launch base in Florida, clearing real estate in ULA’s sprawling manufacturing center for the next-generation Vulcan launch vehicle.
A new system that uses subatomic particles produced high in Earth's atmosphere could provide a view inside volcanoes and help locate people trapped beneath rubble.
Astronomers have discovered a second example of a white dwarf pulsar, a rapidly spinning stellar remnant that could teach scientists more about stellar evolution.
Seven CubeSat missions that demonstrate a variety of services including connectivity and secure communications are being developed by small and medium-sized companies and universities in Greece, following an open call and selection by ESA.
NASA's Aqua satellite spotted giant ice swirls stretching for hundreds of miles in the Sea of Okhotsk off Russia's P'yagina Peninsula.
Prediction is one of the hallmarks of scientific endeavors. Scientists pride themselves on being able to predict physical realities based on inputs. So it should come as no surprise that a team of scientists at Notre Dame has developed a theory that can be used to predict the existence of giant planets on the fringes of an exoplanetary system.
There’s some potentially big news on the hunt for dark matter. Astronomers may have a handle on what makes this mysterious cosmic stuff: strange particles called “axions.”
Italy's Campi Flegrei is showing some troubling early warning signs, but scientists caution that its eruption is far from certain.
A new experiment by IBM computers shows that quantum computers could soon outperform classical digital computers at practical tasks in the next two years.
When Stephen Hawking and I visited the Large Hadron Collider, he hoped for an unexpected physics breakthrough. His dreams may not be impossible.
Gravitational wave astronomy currently can only detect powerful rapid events, such as the mergers of neutron stars or stellar mass black holes. We’ve been very successful in detecting the mergers of stellar mass black holes, but a long-term goal is to detect the mergers of supermassive black holes.
We’ve filed plenty of reports here at UT warning about the potential impact of Starlink and similar satellites on the field of astronomy. We’ve gone so far as to point out that the granddaddy of space-based telescopes – Hubble – has already had some of its images tarnished by passing Starlink satellites. However, SpaceX has been aware of the problem and is working to limit their product’s brightness. The recently launched Gen2 satellites seem to have made a significant step forward – research from a team of amateur astronomers finds that the new Gen2 Starlinks are more than 10x fainter than previous Gen1 iterations.
Rocket Lab's Hypersonic Accelerator Suborbital Test Electron (HASTE) rocket blasted off from NASA's Wallops Flight Facility on Saturday, June 17.

The Paris Air Show is one the oldest and largest aerospace event in the world and of course ESA is there!
Take a look at the very best space photos submitted by Space.com readers, from our moon to deep space and everything in between!
With commercial companies playing an increasingly important role in creating a dynamic and innovative space industry, nine New Space satellite data suppliers have joined the Copernicus programme as ‘Contributing Missions’. Today, at the Le Bourget Paris Air Show, ESA and the European Commission further embraced the era of New Space by welcoming these nine companies into the fold and celebrating the contribution they will make in monitoring our changing world.
We may have already found evidence of an evolving, dynamic kind of dark energy, in the form of the radiation emitted when the first stars appeared in the universe.
Astronomers have found supermassive black holes in smaller galaxies are actually more likely to light up when they’re isolated in vast, cosmic voids.
Everyone knows what a lightsaber is, but what gives them their source of power? Learn all about kyber crystals and what they are.
Lightsabers are the most iconic Star Wars weapons, but their mechanics and complete history aren’t crystal clear. Here’s everything you need to know about them.
Europe's Mercury probe BepiColombo will take a close look at its target planet on Monday(June 19), and we can expect some exciting new images soon after that.
