As it nears 35 consecutive years of space service, the NASA/ESA Hubble Space Telescope has taken another look at a famous supernova remnant. The Veil Nebula is roughly 2,400 light-years away in the constellation Cygnus. It is the remnants of a star that was roughly 20 times as big as our sun and exploded about 10,000 years ago.

This colorful new view combines images that were taken in three different filters by Hubble’s Wide Field Camera 3 and highlights hydrogen, sulfur, and oxygen atoms. It is showing only a tiny fraction of the Veil Nebula, which is roughly as wide as six of Earth’s moons placed side by side. Hubble has previously snapped images of this nebula in 1994, 1997, and 2015.

This new image was taken at a single point in time, but still helps astronomers understand how it has evolved over the past three decades. Combining this image with Hubble observations that were taken in 1994 reveal how individual knots and filaments of gas move over time.
This year, space enthusiasts can also take part in NASA and the Astronomical League’s Hubble’s Night Sky Challenge. Each month, Hubble scientists will release the following month’s list of objects for astrophotographers to photograph. All of the targets from the challenge are visible from Earth, primarily with a telescope or binoculars. The challenge has previously asked observers to observe M1 the Crab Nebula and C39 the Clown Nebula.
For March, skygazers in the Northern Hemisphere are encouraged to look at M44 (aka the Beehive Cluster), the open cluster M48, M67 or the King Cobra/Golden Eye Cluster, and the spiral galaxy C48. Those in the Southern Hemisphere are encouraged to look for planetary nebula C90 in addition to the four cosmic objects listed for the Northern Hemisphere.
Since it first launched on April 24, 1990, the Hubble Space Telescope has taken more than 1.5 million observations and been featured in over 20,000 scientific papers.
