Hello everyone:

Can you believe that it is February already? I sure hope you enjoyed this week’s episode - Our Future on the Moon: Apollo to Artemis with Andy Saunders!

Here’s a new look at CED 90 - a reflection/emission nebula at the tip of the right wing of the Seagull Nebula in Canis Major. This gaseous structure encompasses a cluster of at least five stars exciting the gas around them to glow.

Also known as Sharpless 297 (Sh2-297), this cloud of gas and dust sits roughly 4,000 light years from Earth. Light in this image left this nebula around the same time the final wooly mammoths met their demise, coal was first burned for fuel, and some clever person invented the abacus.

Recorded on the night of 7 December, using the 0.6-meter CHI-1 telescope in Chile, available from Telescope Live. This composite image is composed from six 10-minute exposures, recorded in wavelengths showing hydrogen (red), sulfur (green) and oxygen (blue).
