A glancing collision between two galaxies in the distant past triggered a firestorm of starbirth in the smaller of the two, leaving one side relatively intact while the other was set ablaze by gravitational stresses.
Late winter sunlight hitting the surface of Mars at a low angle contributes to a striking Mars Reconnaissance Orbiter image of sandy terrain dusted with frost, producing graceful shapes that evoke… a duck?
NASA’s OSIRIS-REx spacecraft is busy mapping the asteroid Bennu, revealing a remarkably fractured surface littered with countless rocks of varying sizes giving it the appearance of a jumbled rubble pile in space.
A new “deep field” image by the Hubble Space Telescope combines 7,500 images collected during earlier deep exposures to produce a stunning image of an area roughly the size of the full Moon that contains more than 250,000 galaxies.
The Atacama Large Millimetre/submillimetre Array, or ALMA, is in the process of studying stellar nurseries in nearby galaxies to learn more about the factors influencing rates of star formation and the roles a host galaxy’s overall structure and dynamics might play.
M82, a favourite target for amateur and professional astronomers alike, is the nearest starburst galaxy with a brilliant core 100 times more luminous than the Milky Way’s. Astronomers have detected and mapped the galaxy’s magnetic field in a dramatic composite image.
