In another SpaceX milestone, billionaire Jared Isaacman and company crew trainer Sarah Gillis took turns floating just outside their Crew Dragon capsule early Thursday in the first privately-financed spacewalk in the history of space exploration.
If you enjoyed this summer’s display of aurora borealis, thank the Sun’s corona. The corona is the Sun’s outer layer and is the source of most space weather, including aurorae. The aurora borealis are benign light shows, but not all space weather produces such harmless displays; some of it is dangerous and destructive.
SpaceX's Starship likely won't be able to fly again until late November at the earliest, because the FAA and partner agencies need more time for licensing reviews.
A new brightness forecast for Comet Tsuchinshan-ATLAS whets our hopes for a fine appearance in late September and early October.
Helen Sawyer Hogg stood at the front of a small but growing force of woman astronomers in the first half of the 20th century. This is her story.
The sun unleashed an X1.3-class solar flare on Thursday (Sept. 12), increasing the likelihood of widespread auroras this weekend.
The Polaris Dawn crew called down to Earth to honor the anniversary of 9/11, and to do a book-reading event to support St. Jude Children's Research Hospital.
Two private astronauts conducting the first commercial spacewalk did not so much float out of their spacecraft as they did "stand up."
A new book looks at the latest scientific insights versus a key question in astronomy and space science.
Hurricane Francine, the sixth storm of this year's Atlantic hurricane season, made landfall on the Louisiana coast late afternoon on Wednesday.

I’ve been an avid stargazer for a fair few decades now and not once have I seen anything that makes me believe we are being visited by aliens! My own experiences aside, there’s no evidence of alien visitations but it seems much of the population believes anything that they cannot immediately identify in the sky MUST be ailens. A new paper suggests there are costs associated with increasing claims such as disctractions to government programs and background noise that hampers science communication. How on Earth should we deal with it? If debunking doesn’t work, then maybe its time for a scientific investigation.
