The U.S. Space Force launched its final Global Positioning System (GPS) III satellite into medium Earth orbit in the predawn hours of Tuesday aboard a SpaceX Falcon 9 rocket.
The Universe looks mighty impressive when visualized with X-ray instruments. More importantly, X-ray images provide vital scientific insights by revealing features in the Universe that are not observable in visible light. The same is true of our Solar System, which has been difficult because of the challenges of separating local emissions from the rest of the Milky Way galaxy. In a recent study, a team from the Max Planck Institute for Extraterrestrial Physics (MPE) managed, for the first time, to disentangle the X-ray glow of our Solar System from deep space.
NASA engineers have shut down another instrument on Voyager 1 to preserve the power of the most distant spacecraft ever sent into space.
The ring system of Saturn is one of the most magnificent and recognizable features in our solar system. The rings are not solid, but are made up of billions of small pieces of ice and rock ranging in size from tiny dust particles to chunks as large as mountains. These particles orbit Saturn at different speeds, giving the rings their distinctive appearance.
A SpaceX Falcon 9 rocket carrying 25 Starlink satellites lifted off from Vandenberg Space Force Station in California on April 19. The mission featured the 600th landing of a Falcon first stage.
Liquid water is the primary ingredient for life as far as we can determine. The search for habitable exoplanets focuses on this fact. Exoplanet scientists sift through data trying to determine which worlds might be in their stars' habitable zones, a zone with just the right amount of star energy to maintain liquid surface water.
A huge geological structure on Mars resembling a bathtub ring may be evidence of an ocean that once covered a third of the Red Planet.
It turns out that living in space can have a lasting impact on how your brain works, researchers have found.
These global night sky cams let you hunt for Lyrids from the comfort of your own home.
New missions mean new capabilities - and one particularly interesting new mission is finally up and running. Data is starting to come in from SPHEREx, the medium-class surveyor that is mapping the entire sky every six months. A paper based on some of that early data was recently published in The Astrophysical Journal, mapping ice and compounds called Polycyclic Aromatic Hydrocarbons (PAHs) throughout some interesting regions of our Milky Way.
Spectators along the beach in Cape Canaveral, Florida, enjoy a spectacular Sunday morning launch, taking in the view of a Blue Origin New Glenn rocket blasting off carrying a next-generation cellular broadband satellite.

Blue Origin launched the company’s third New Glenn rocket Sunday, re-flying and successfully recovering a previously used first stage. But the rocket’s payload, a direct-to-cellphone communications satellite, ended up in the wrong orbit, the company said.
The NASA/ESA Hubble Space Telescope looked at a scene it first captured in 1997 in honour of 36th anniversary: a small portion of a star-forming region about 5000 light-years away in the constellation Sagittarius, known as the Trifid Nebula. The image shows changes over incredibly short timescales and instills a sense of awe and wonder about our ever-changing Universe.
'I'm honored to be a part of the team continuing this adventure for a new generation of Starfighters, both young and old.'
The Lyrid meteor shower peak is almost here, and we may be in store for spectacular fireballs and shooting stars.
State-of-the-art simulations shed light on how galaxies die — and how we can determine the cause of death.
Our universe is full of mysteries, but few are as perplexing as the dark, tiny galaxies that hover around larger ones like the Milky Way.
A remote Antarctic research team became the only people on Earth to witness a rare annular solar eclipse — and one scientist had to improvise to capture it.
The Vera C. Rubin Observatory was built with an ambitious purpose in mind. As part of its 10-year Legacy Survey of Space and Time (LSST), the Rubin Observatory will gather about 30 petabytes of data. This will include creating an inventory of the Solar System, transient objects (such as supernovae and variable stars), and mapping the Milky Way. Using preliminary data gathered by the Observatory, scientists have already discovered 11,000 new asteroids in the Solar System. These results were confirmed by the International Astronomical Union's Minor Planet Center (IAU-MPC).
SpaceX will launch a new GPS satellite for the U.S. Space Force early Tuesday morning (April 21), and you can watch the action live.
Blue Origin, the space launch company founded by Jeff Bezos, achieved a successful recovery of its first reused orbital-class rocket, but the payload it put into space was left in the wrong location.
