"Dwarf Galaxies' Star-Producing Strategy: A 10-Million-Year Silent Surge"

University of Michigan researchers have discovered that less evolved dwarf galaxies have larger regions of star formation due to a 10-million-year delay in blowing out gas and dust. In these pristine galaxies, massive stars collapse into black holes instead of exploding as supernovae, allowing star-forming regions to retain their gas and dust and form more stars. This delay also offers astronomers a glimpse into scenarios similar to the cosmic dawn after the Big Bang. The findings have implications for understanding the properties of galaxies observed by the James Webb Space Telescope.

Webb Telescope Uncovers Unseen Structures in Famous Supernova

Astronomers studying the famous supernova SN 1987A have made new observations using the James Webb Space Telescope, revealing a central structure shaped like a keyhole packed with clumpy gas and dust ejected by the explosion. The dense dust is so thick that even the advanced telescope cannot see through it, creating the "hole" shape. The observations also revealed small crescent-like structures believed to be part of the outer layers of gas shot out by the explosion. These new findings provide crucial clues to understanding how a supernova develops over time.
