Faced with threatening weather from Hurricane Ian, NASA managers decided Monday to haul the $4.1 billion Artemis 1 rocket off its launch pad and back to the protection of the agency’s Vehicle Assembly Building, likely ending any chance of launching the unpiloted moonshot before November.
How big a space rock must be to no longer be just a mesmerizing sight? What size is big enough to wreck a whole city? And a continent? And what else does the damage depend on?
The Celestron StarSense Explorer DX 6 Schmidt-Cassegrain telescope is a very handy telescope and you can now save £50.
Artemis 1 will begin rolling back from the launch pad on Monday (Aug. 26) to seek out shelter in NASA's nearby Vehicle Assembly Building in Florida.
There's a new addition to the Lego Star Wars Ultimate Collector Series line: the biggest ever Razor Crest model - as seen in The Mandalorian.
An astronaut's photo of Mount Ruapehu, the real-life "Mount Doom" volcano shows the contrast between the hydrothermal lake at its summit and the snow surrounding its peak.
The explosive Hunga Tonga-Hunga Ha'apai volcanic event spewed so much moisture that it increased the global average of atmospheric water vapor by 5%.
Be sure to observe Jupiter this week, during its finest apparition of a lifetime.
The summer solstice marks the start of astronomical summer and the longest day of the year. Here we explore when the summer solstice occurs and why.
Blue stars are extreme in every way. They're the hottest, most massive and shortest-lived stars in the universe.
The Sun never stops shining in space, and it is much more intense there than on the surface of the Earth. So what if we could gather that energy up in space then beam it down to Earth?
A peculiar repeating fast radio burst seems to be coming from a dynamic environment in an otherwise uninteresting region, leaving researchers scratching their heads as to the burst’s origin.
On Monday (Sept. 26) at 7:14 p.m. EDT (2314 GMT), if all goes well, DART will crash into Dimorphos in an attempt to alter the moonlet's trajectory.
Black holes go boom in several ways.
Skywatchers will get a rare opportunity to see Jupiter in its full glory when its opposition happens at the same time as its closest approach to Earth.
Recent work by NASA and Congress seeks new solutions for space debris, which has been a U.S. government priority amid anti-satellite testing and the rise of satellite megaconstellations.

A NASA spacecraft is aiming to slam into a stadium-size asteroid at more than 14,000 mph Monday in a planetary defense experiment to test a technique that could be used in the future to divert threatening asteroids off a collision course with Earth.
One of the more famous features of Space Age 2.0 is the rise of the commercial space industry, also known as “NewSpace.” While the space agencies of the world plan to send astronauts back to the Moon (this time, to stay), crewed missions to Mars, and robotic missions to every corner of the Solar System, NewSpace companies are offering cost-effective launch services, sending commercial astronauts to space, and commercializing Low Earth Orbit (LEO). There’s also the prospect of space tourism, with companies like Virgin Galactic, Blue Origin, and SpaceX offering suborbital flights, trips to LEO, and beyond!
Way back in 1979, astronomers spotted two nearly identical quasars that seemed close to each other in the sky. These so-called “Twin Quasars” are actually separate images of the same object. Even more intriguing: the light paths that created each image traveled through different parts of the cluster. One path took a little longer than the other. That meant a flicker in one image of the quasar occurred 14 months later in the other. The reason? The cluster’s mass distribution formed a lens that distorted the light and drastically affected the two paths.
Photosynthesis is probably the most important chemical reaction for life on Earth. It is the process plants use to transform sunlight into energy it can use. Through it, plants can produce carbohydrates they can use (and we can eat when we harvest plants), generating oxygen as a by-product. Photosynthesis is why Earth’s atmosphere is about 20% oxygen. No photosynthesis, no life on Earth as we know it.
