Galaxies

Astronomers have observed a supermassive black hole in the galaxy VV 340a launching a wobbling jet that expels star-forming gas at a rate of about 19 solar masses per year. This process, captured using multiple telescopes including the James Webb Space Telescope, demonstrates how black holes can regulate galaxy evolution by limiting new star formation. The jet's precession, resembling a spinning top, enhances its interaction with surrounding gas.

Astronomers using the James Webb Space Telescope have re-evaluated the mysterious 'little red dots,' distant galaxies that initially appeared impossibly bright. New analysis suggests these galaxies host modest 'baby' black holes rather than massive ones or excessive stars. This finding resolves tensions in models of early universe galaxy formation.

An Indian research team has discovered a galaxy resembling the Milky Way, naming it Alaknanda after a sacred river. The finding was made using the James Webb Space Telescope. Researchers Rashi Jain and Yogesh Wadadekar from NCRA-TIFR led the effort.

An isolated galaxy in the Local Void, NGC 6789, continues to form new stars despite lacking apparent gas fuel. New deeper images reveal no signs of mergers or gas inflows that could explain the phenomenon. The mystery of its star formation deepens, challenging astronomers' understanding of galactic evolution.
