"Cambridge, MA - Two separate teams of scientists have identified major challenges for the development of life in what has recently become one of the most famous exoplanet systems, TRAPPIST-1. "
"The teams, both led by researchers at the Harvard-Smithsonian Center for Astrophysics (CfA) in Cambridge, Mass., say the behavior of the star in the TRAPPIST-1 system makes it much less likely than generally thought, that planets there could support life."
Evolver social movement & the Hive to Thrive speaker series hosted Harvard University director of astronomy Avi Loeb for a wide ranging discussion. From the nature of scientific discovery to possible origins of FRBs (Fast Radio Bursts) emanating from the cosmic background radio noise. Produced...
"An Earth-sized planet next door: that was the startling announcement last August. Astronomers had found an exoplanet orbiting the sun’s closest stellar neigh- bor, a cool red dwarf star called Proxima Centauri (1). Even better, the nearby world orbited within its parent star’s habitable zone, meaning liquid water could exist on the planet’s surface, which raised the prospects for its harboring life."

"As the Faculty of Arts and Sciences works to address a “concerning” lack of diversity in the body, some have turned to astronomy professor John A. Johnson’s efforts as an example of creating opportunities for historically underrepresented minorities.
Harvard Graduate student Marion Dierickx recent paper featured:
"The 11 farthest known stars in our galaxy are located about 300,000 light-years from Earth, well outside the Milky Way's spiral disk. New research by Harvard astronomers shows that half of those stars might have been ripped from another galaxy: the Sagittarius dwarf. Moreover, they are members of a lengthy stream of stars extending one million light-years across space, or 10 times the width of our galaxy."
"Our Earth consists of silicate rocks and an iron core with a thin veneer of water and life. But the first potentially habitable worlds to form might have been very different. New research suggests that planet formation in the early universe might have created carbon planets consisting of graphite, carbides, and diamond. Astronomers might find these diamond worlds by searching a rare class of stars.
"'This work shows that even stars with a tiny fraction of the carbon in our solar system can host planets,' says lead author and Harvard University graduate student Natalie Mashian....
