NASA will bring four astronauts back to Earth early due to a health issue, leaving the International Space Station with just three crewmembers. But that's the way it used to be.
Black holes are objects so dense that they warp space time to an extreme degree. They may be better described as places than objects, but regardless, the point stands. So strong is their effect that not even light can esacpe their grasp.
The DJI Mavic 4 Pro is a powerful drone featuring three cameras that can capture images in 100MP resolution and video in 6K and it's still at its lowest price.
"It's about the themes of love and sacrifice and family. And maybe asking ourselves, 'What am I going to do that adds quality to this world?'"

On Monday, L3Harris Technologies, announced the intended sale of a majority stake in its Space Propulsion and Power Systems business to AE Industrial Partners, shifting control over one of its marquee engines: the RL10.
NASA will return four astronauts to Earth early from the International Space Station due to a medical concern with one of the Crew-11 astronauts. Here's the latest news.
New models suggest that Europa has very little tectonic activity at its seafloor, which is potentially catastrophic news for the hopes of finding alien life within its ocean.
The closest planet to the Sun is Mercury. It's a tiny world, even smaller than Saturn's moon Titan and Jupiter's moon Ganymede. That's unusual for a planetary system. Most star systems have a large world between the size of Earth and Neptune orbiting much closer than Mercury. A new study has figured out how these close-orbiting super-Earths form and clues about why they are so common.
The medical evacuation of SpaceX's Crew-11 astronauts from the International Space Station shouldn't interfere with Artemis 2's launch to the moon, NASA Administrator Jared Isaacman says.
A magical encounter in northern Finland blends ancient folklore, swirling auroras and an unexpectedly curious fox.
Jupiter reaches opposition overnight on Jan. 10, when it appears its brightest in 2026 opposite the sun in Earth's sky.
Planets, stars, and star clusters, oh my!
"WIMPs are still the leading candidate for dark matter, but billions of dollars of experiments have been done, only getting stronger and stronger upper limits, so alternative scenarios have to be considered."
These moonless evening offer the winter Milky Way arching high over the world. And, when will Betelgeuse stand straight over Sirius for you?

Four space station fliers have been told to cut their mission short and return to Earth ahead of schedule because of an apparently serious medical issue affecting an unidentified crew member, NASA announced Thursday.
NASA has decided to bring the four astronauts of SpaceX's Crew-11 mission home from the International Space Station early due to a medical issue experienced by a crewmember in orbit.
"Nothing in my professional training as an X-ray astronomer had prepared me for something like this."
Mars has a curious past. Rovers have shown unequivocal evidence that liquid water existed on its surface, for probably at least 100 years. But climate models haven’t come up with how exactly that happened with what we currently understand about what the Martian climate was like back then. A new paper, published in the journal AGU Advances by Eleanor Moreland, a graduate student at Rice University, and her co-authors, has a potential explanation for what might have happened - liquid lakes on the Red Planet would have hid under small, seasonal ice sheets similar to the way they do in Antarctica on Earth.
