The swirls of the galaxy IC 1776 stand in splendid isolation in this image from the NASA/ESA Hubble Space Telescope. The galaxy lies over 150 million light-years from Earth in the constellation Pisces.
IC 1776 recently played host to a
catastrophically violent explosion – a supernova – which was discovered in 2015
by the Lick Observatory Supernova Search, a robotic telescope which
scours the night sky in search of transient phenomena such as supernovae. A
network of automatic robotic telescopes is spread across the globe, operated by
both professional and amateur astronomers. They reveal short-lived astronomical
phenomena such as wandering asteroids, gravitational microlensing, or
supernovae.
Though not visible in this image, Hubble
investigated the aftermath of the supernova – known as SN 2015ap – during two
different observing programs, both designed to comb through the debris left by
supernovae explosions to better understand these energetic events. A variety of
telescopes automatically follow up the detection of supernovae to obtain early
measurements of their brightness, as well as their spectra. Complementing these
early measurements with later observations, which reveal the lingering energy
of supernovae, can shed light on the systems that produce these cosmic
cataclysms in the first place.
