This weekend, an astronomer spotted a small asteroid just hours before the space rock crashed into Earth's atmosphere and met its fiery demise. It was "probably a once-in-a-lifetime" moment, they said.
Scientists conducted experiments to create conditions replicating the hot gas in gigantic galaxy clusters. The hope is the experiment series will reveal more about the conditions within giant groups of galaxies.
NASA's Artemis 1 moon rocket, the first Space Launch System megarocket, rolls to the launch pad on Thursday, March 17. "It's gonna be amazing," NASA Artemis launch director Charlie Blackwell-Thompson said during a news conference Monday.
Geopolitical tensions won't keep an American astronaut and two Russian cosmonauts from returning to Earth together as planned this month. Mark Vande Hei and two cosmonauts will still travel home together on March 30.
The California company's two-stage Launch Vehicle 0009 lifted off from the Pacific Spaceport Complex on Alaska's Kodiak Island today, just weeks after a failed launch in February.
When NASA astronaut Mark Vande Hei launched into space 11 months ago, he did not know how long he would be off the planet, let alone that he would be up there long enough to set any records. At 340 days and counting, he now has the U.S. record for the longest single spaceflight.
The Event Horizon Telescope (EHT) is gearing up for its 2022 campaign, which includes seven days of remote observations. The telescope network will focus on dramatic objects around the universe including black holes, galaxies and quasars, which are superbright objects with black holes in the middle.
The storms aren't likely to cause any harm on Earth, save for possibly muddling radio transmissions and affecting power grid stability at high latitudes - however, the aurora borealis could be seen at lower latitudes that usual.
The Perseverance rover is on a long-term quest to better understand the potential for Mars life. While other Mars missions are searching for signs of water, the rover is going a step further by caching the most promising rocks for a sample-return mission.
Solar cycle 25 is kicking off in style. Our sun has a cycle of activity and as it becomes more active, there will be more sightings of the northern (and southern) lights. That is what is happening this winter.
