MIT 6 Sep 2021, 15:00 UTC By definition, dwarf galaxies are small and dim, with just a fraction of the stars found in the Milky Way and other galaxies. There are, however, giants among the dwarfs: Ultra-diffuse galaxies, or UDGs, are dwarf systems that contain relatively few stars but are scattered over vast regions. Because they are so diffuse, these systems are difficult to detect, though most have been found tucked within clusters of larger, brighter galaxies.
MIT AeroAstro 3 Sep 2021, 20:44 UTC As a not-so-distant future that includes space tourism and people living off-planet approaches, the MIT Media Lab Space Exploration Initiative is designing and researching the activities humans will pursue in new, weightless environments.
American Astronomical Society 3 Sep 2021, 20:31 UTC Solar activity sometimes stays trapped close to the Sun’s surface — but sometimes it breaks free in enormous ejections of hot plasma. What determines whether a solar flare stays confined or is followed by a catastrophic eruption? A new study reveals clues.

American Astronomical Society 1 Sep 2021, 14:13 UTC In the early solar system, terrestrial planets like Mercury, Venus, Earth and Mars are thought to have formed from planetesimals, small early planets. These early planets grew over time, through collisions and mergers, to make them the size they are today. The material released from these violent collisions is commonly thought to have escaped and orbited around the sun, bombarding the growing planets and altering the composition of the asteroid belt. But the asteroid belt does not seem to contain a record of this impact debris, which is a mystery that has been stumping astronomers and astrophysicists for decades. Two researchers from Arizona State University’s School of Earth and Space Exploration, former NewSpace Postdoctoral Fellow Travis Gabriel and doctoral student Harrison Allen-Sutter, were curious about this discrepancy and set about creating high-end computer simulations of the collisions, with surprising results.
