Center for Astrophysics A Hubble image of the M-dwarf star Proxima Centauri, our closest stellar neighbor about four light-years away. Proxima hosts two planets, and is known to actively flare. Astronomers studying the suitability for life evolving on exoplanets around M-dwarf stars have completed a multi-wavelength analysis of an extreme flare on Proxima Cen. Hubble/ ESA/NAS The prospects for life around low-mass, cool M-type stars have been extensively discussed because these stars are the most common ones in the galaxy, and they frequently host Earth-sized planets in their habitable zones (orbits where the surface temperatures can support liquid water). Unfortunately for the prospects of life, however, these stars also exhibit higher levels of stellar activity and flaring than do more massive, solar-type stars, and flares can gradually deplete a planet’s atmosphere of molecules needed for life. Moreover, these hostile conditions persist in some fashion throughout ....
Center for Astrophysics P. Marenfeld & NOAO/AURA/NSF Cambridge, MA – In 1983, astrophysicists at the Center for Astrophysics | Harvard & Smithsonian (CfA) released a cosmic map using 2,400 galaxies. Now, CfA scientists are aiming to map 30 million. In the largest quest yet to map the universe, an international team of researchers is using DESI, or the Dark Energy Spectroscopic Instrument, to survey the skies. Observations officially began today, May 17, at Kitt Peak National Observatory near Tucson, Arizona; the mission will last five years with the goal of mapping 30 million galaxies. By surveying a vast volume of space, the scientists of the DESI collaboration – including a dozen from the CfA – will be able to address a myriad of questions in modern cosmology: how does the early universe create large-scale structures, how does gravity cause matter to collect and form galaxies, and what might be driving the enigmatic acceleration of the expansion of the univ ....
