An analysis of the craters on Bennu’s surface provides evidence that the rubble pile asteroid is protected from smaller impacts by the boulders scattered on the surface. Plus, the SLS Wet Dress Rehearsal, dwarf galaxies around M81, and this week in rocket history, we look back at the X-15 hypersonic plane.
Researchers using the Chandra X-ray Observatory have found that a known pulsar is moving through a supernova remnant at over one million miles per hour. Plus, the life and death of stars, new pictures of the Large Magellanic Cloud, and all of the SpaceX rocket launches.
Observations of V1674 Hercules reveal a nova produced by the white dwarf star that dimmed in only one day. Additionally, the strange star wobbles every 501 seconds, producing flashes in visible and X-ray light. Plus, more results from the 240th meeting of the American Astronomical Society, a farewell to SOFIA, and What’s Up is the June solstice.
Two seemingly unrelated stars, each with several exoplanets, turn out to be members of an enormous, diffuse star cluster. Plus, baby squid go to the ISS, new images from China’s Zhurong rover, a brightening blazar, and an interview with scientist Sophia Gad-Nasr and artist Cathrin Machin about how art and science work together.
In new research, scientists examined the populations of stars observed by the Kepler and K2 missions and found that the solar systems were different depending on the type of star involved. Plus, CHIME results, a brown dwarf’s atmosphere, a stream of stars in the Milky Way, and an interview with PSI’s Dr. Candice Hansen about the recent Ganymede flyby of NASA’s Juno spacecraft.
The most precise measurements of the universe’s composition and growth have been reported in almost thirty new papers based on Dark Energy Survey observations of 229 million galaxies and covering one-eighth of the sky. Plus, stories from the first day of the AAS conference, all the volcanoes, and mission updates.
