Hubble’s view of UGC 5460, a sparkling spiral in Ursa Major, reveals its starry bar and blue clusters-alongside a nearby Milky Way star just 577 light-years away.

UGC 5460, home to supernovae SN 2011ht and SN 2015as, became a Hubble target for programs exploring the diverse nature of stellar explosions.

SN 2015as was a core-collapse supernova, triggered when a massive star’s core exhausted its fuel and collapsed, unleashing a powerful rebound explosion.

Hubble observations of SN 2015as will help researchers understand what happens when the expanding shockwave of a supernova collides with the gas that surrounds the exploded star.

SN 2011ht may have been a true core-collapse supernova-or a supernova impostor, erupting from a rare, volatile luminous blue variable star.

Hubble aims to find a stellar survivor at SN 2011ht’s site, distinguishing whether the eruption was a true supernova or a luminous blue variable’s outburst.
