China launched a high-power communications satellite Saturday on a mission to connect airline passengers, maritime vessels, and other users across China, Southeast Asia, and remote routes between the Asia-Pacific region and North America.
The rapid decline of the British-Irish Ice Sheet thousands of years ago may hold lessons for how melting ice sheets in Greenland and Antarctica will influence sea-level rise in the future.
We're unprepared for when E.T. reaches out to us. A team of experts is determined to change that.
If you surfed the web this morning, you may have seen news of the latest existential threat to humanity: a “planet killer” asteroid named 2022 AP7. Luckily for us 2022 AP7 “has no chance to hit the Earth currently”, according to Scott Sheppard at the Carnegie Institution for Science.

The first test flight of Boeing’s Starliner crew capsule with astronauts has been delayed from February to April 2023, moving the mission after a busy stretch of crew and cargo missions to the International Space Station, and allowing more time for engineers to address problems discovered on an unpiloted test flight earlier this year, NASA said Thursday.
A fire alarm on Earth prevented the launch of Northrop Grumman's NG-18 cargo ship for NASA on Nov. 6.
NASA named 18 space agencies, organizations and individuals who will watch the Orion spacecraft as it flies around the moon, after launching with Artemis 1 no earlier than Nov. 14.
The spiral galaxy Messier 99 got the star treatment from two European Southern Observatory instruments.

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.
