Many galaxies blast huge, wide-angled flows of material outward from their centres, pushing to their outer edges enough dust and gas each year that otherwise would have formed more than a thousand stars the size of our Sun. A team led by University of Maryland scientists has found the driving force behind these massive molecular outflows.
On July 14th, NASA’s New Horizons spacecraft will flyby Pluto, offering the first close-up look at that small, distant world. You can help decide what names will be used on subsequent maps of the dwarf planet and its largest moon, Charon, as the SETI Institute announces the launch of its “Our Pluto” campaign.
An international scientific team using NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) has discovered a cloud produced by a supernova explosion 10,000 years ago that contains enough dust to make 7,000 Earths, showing that supernovae are capable of producing a substantial amount of the material from which planets can form.
