Northrop Grumman is set to launch the penultimate flight of its current Antares rocket configuration — with Russian engines and a Ukrainian first stage structure — to begin a resupply mission Sunday delivering more than four tons of cargo to the International Space Station.
Historical data about solar storms carved in trees, and it’s a bit worrying. Falcon Heavy’s back after 40 months of absence. There’s a meteor shower and a total lunar eclipse in the coming days. And JWST gave us yet another version of Pillars of Creation.
Tragically sometimes stars engulf their own planets. While most stars are able to quickly cover up the evidence for their crime, a new study by astronomers has revealed that in some cases the evidence can linger for up to two billion years.
Iran's Revolutionary Guard successfully launched a new rocket capable of sending satellites into orbit on Saturday (Nov. 5).
In 1961 astronomers discovered a powerful x-ray source coming from the constellation Cygnus. Not knowing what it was, they named the source Cygnus X-1. It’s one of the strongest x-ray sources in the sky, and we now know it is powered by a stellar-mass black hole. Since it is only about 7,000 light-years away, it also gives astronomers an excellent view of how stellar-mass black holes behave. Even after six decades of study, it continues to teach us a few things, as a recent study in Science shows.
Our roundup of the best star trackers for astrophotography for wide-field and deep sky imaging.
You can see a Blood Moon total lunar eclipse on Nov. 8, the last until 2025. Here's how to watch it online for free.
New research indicates that certain areas of the Martian crust have a higher silica content than expected, upending the long-held theory that the crust is uniformly basaltic.
Only a handful of people have ever set foot on the moon. We take a look at this super exclusive club, who they were, and what enabled them to make that incredible journey.
The basic construction of China’s space station is complete, following a maneuver to shift the recently arrived Mengtian module to its permanent docking port.
The U.S. military's X-37B robotic space plane just passed 900 days in orbit on its latest hush-hush mission, adding to the program's flight-duration record.
Fertility treatments and a bioprinter that can manufacture knee cartilage will fly to the International Space Station Sunday (Nov. 6) aboard a Cygnus cargo spacecraft.
Humans in space have to eat. In the early days of space exploration, they got to eat paste and drink Tang (or so the legends tell us). That’s hardly a great long-term diet. Plants should be in there, too. And, astronauts aboard the ISS have been growing gardens in space for years.

Rocket Lab’s Electron launcher placed a small Swedish atmospheric research satellite into an on-target polar orbit Friday, but an attempt to recover a booster stage with a helicopter was aborted after a brief telemetry loss from the rocket on descent.
Researchers using the IceCube Neutrino Observatory have detected neutrinos emanating from the energetic core of an active galaxy millions of light-years away. Neutrinos are difficult to detect, and finding them originating from the galaxy is a significant development. What does the discovery mean?
The U.S. government has officially started to explain some of the most infamous UFO encounters of the last decade, with China and weather balloons as top offenders.
The study of extrasolar planets has led to some astounding discoveries, many of which have defied the expectations of astronomers and challenged our notions about the forms planetary systems can take. For example, the discovery of Jupiter-sized planets that orbit closely to their stars (“Hot Jupiters”) defied what astronomers suspected about gas giants. Previously, the general consensus was that gas giants form beyond the “Frost Line” – the boundary beyond which volatile elements (like water) freeze solid – and remain there for the rest of their lives.
A NASA Venus mission will have to wait at least three more years to launch due to issues with the agency's Psyche asteroid probe.
If the title of 'Star Wars: Episode IV' is 'A New Hope' then the title of 'Andor' episode VII should be 'Abandon All Hope.'
The first crewed flight of Boeing's Starliner astronaut taxi has been pushed back by two additional months, to April 2023.

NASA’s Space Launch System moon rocket arrived back on its Florida launch pad Friday, ready for a series of overnight launch opportunities beginning Nov. 14 to begin a crucial, long-delayed test flight that officials hope will set the stage for future lunar missions with astronauts.
