As Comet C/2019 Y4 (ATLAS) moved
through Ursa Major on February 2,
2020, it passed the Owl Nebula
(M97, top) and edge-on spiral galaxy
M108. The Asteroid Terrestrial-
impact Last Alert System (or ATLAS)
survey discovered it December 28,
making it the final comet discovered
in 2019. • Gerald Rhemann - EXHAUST GAS
NGC 6883 is an open cluster in the
constellation Cygnus. This deep
image shows a bubble of interstellar
gas being blown away from the
Wolf-Rayet star WR 134, a star that
outshines our Sun by 400,000 times.
