    Explanation: Two protostars are hidden in a single pixel near the center of a striking hourglass-shaped nebula in this near-infrared image from the James Webb Space Telescope. The actively forming star system lies in a dusty molecular cloud cataloged as Lynds 483, some 650 light-years distant toward the constellation Serpens Cauda. Responsible for the stunning bipolar outflows, the collapsing protostars have been blasting out collimated energetic jets of material over tens of thousands of years. Webb's high-resolution view shows the violence of star-formation in dramatic detail as twisting shock fronts expand and collide with slower, denser material. The premier close-up...

    The latest discoveries were made by Webb's Mid-Infrared Instrument (MIRI) instrument as part of the James Webb Observations of Young ProtoStars (JOYS+) program and revealed key chemical ingredients astronomers are looking for in the search for distant worlds that could be home to life.Given that they are young protostars, IRAS 2A and IRAS 23385 do not appear to have planets in orbits around them yet. However, the detections of organic molecules around them are promising indicators for regions of future habitability.Along with the detection of ethanol, MIRI has also detected what astronomers believe is probably acetic acid, an ingredient commonly...
