A trio of asteroid-related stories crossed our emails this week: Bennu’s sample is on schedule for next year’s return, researchers have developed a tool to measure an asteroid’s density distribution, and 3200 Phaeton’s rotational period has accelerated. Plus, JWST’s new Pillars of Creation image, and this week in space history, we look back at Venera 4.
Using pockets of gas found in tiny crystals, scientists have created a timeline for the formation and eruption of four supervolcano events in northern Chile more than twenty million years ago. Plus, rocket launches, gorgeous new space images, and an interview with Jian-Yang Li about the upcoming DART mission’s impact.
A population study of 43 exoplanets orbiting M-dwarf stars used both the transit method and radial velocity method to find the densities of the worlds and a surprising pattern emerged. The planets are less dense than expected, suggesting they are not purely rock but half-rock and maybe half-water. Plus, star factories in the Milky Way, glaciers on ancient Mars, and This Week in Space History.
Starting with the stunning release of JWST’s first image of galaxy cluster SMACS 0723 on July 11, the bonanza continued the morning of July 12 with newly released images of Stephan’s Quintet, the Carina Nebula, the Southern Ring Nebula, and exoplanet WASP-96b. Plus, that controversial name and what’s ahead for the newest space observatory.
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.
