A classified payload for the National Reconnaissance Office is closed up in the nose cone of a SpaceX Falcon 9 rocket for liftoff Wednesday from California’s Central Coast, debuting a brand new booster that will land back near the launch site for reuse on another national security mission later this year.
A Chinese satellite pulled a defunct navigation satellite out of the way of other satellites on January 22nd. The satellite, called SJ-21, appeared to operate as a space tug when it grappled onto the navigation satellite from the Chinese CompassG2 network. The operation details didn’t come from Chinese authorities but a report by ExoAnalytic Solutions, a commercial space monitoring company.
A powerful solar flare has been traveling through space and it will arrive at planet Earth Wednesday (Feb. 2).
A detailed new telescope image of the heart of our galaxy is now giving researchers their best view yet of hundreds of strange magnetic filaments seen nowhere else.
NASA's Mars rover Perseverance has snagged a sample to replace the material that got stuck in its throat.
SpaceX appears to be targeting Wednesday (Feb. 2) to fly its next batch of Starlink satellites, setting up what could be a coast-to-coast launch doubleheader.
Space shuttle Challenger exploded just 73 seconds after liftoff on Jan. 28, 1986, changing NASA's space program forever.
We’re never able to see the far side of the moon from the Earth, but that doesn’t mean it’s that different. Recently rovers and satellites have started exploring the lesser-known side of the moon. They found a slightly different geology than that discovered on the near side, which might have implications for navigating the far side in the future.
Spacecraft controllers started powering up James Webb Space Telescope's four cutting-edge instruments as they prepare to take test images of the first star.
In 2020, astronomers thought they'd found something incredible: the second so-called Earth Trojan asteroid ever seen. Now, a new team of researchers has confirmed that it's real.
Astronomers will go to great lengths for science. Recently, dozens of astronomers had the misfortune of traveling to one of the most tempting locales in the southwestern US – Las Vegas. But they weren’t there for the city’s bright lights – they were there to observe a very dim light of a star thousands of light-years away. And what they specifically wanted to see was the light from that star blink out for a few seconds. That lack of light provided the exact kind of data they needed to help them determine the size of Eurybates, one of the Trojan asteroids that will be the focal point of NASA’s Lucy mission.
You may have heard of the Trojans, two vast swarms of asteroids that lead and trail Jupiter on its orbit around the Sun.
Astronomers say there are 100 billion to 200 billion galaxies in the universe. But accurately counting the number of galaxies depends on several factors.
Today (Feb. 1) marks a new moon and the first day of a new lunar year.
