Excellent morning. It is February 2, and these days’s symbol issues an emission nebula about 5,000 light-years away within the Cygnus constellation.

Found out greater than 230 years in the past by means of William Herschel, astronomers imagine the Crescent Nebula is shaped by means of the mix of an lively stellar wind from a Wolf-Rayet megastar at its core, colliding with slower-moving subject matter ejected previous within the megastar’s lifetime. In the long run, this will have to all cross supernova, which might be fairly impressive.

Will you or I be alive to peer it? Most certainly no longer.

However within the intervening time, we will benefit from the nebula for what it’s. This picture used to be captured by means of Ars reader 1Zach1 with an Astro-Tech AT80ED Refractor telescope. It used to be the product of eleven hours of integration, or 228 exposures each and every lasting 3 mins. It used to be taken in rural southwestern Washington.

Have an excellent weekend, everybody.
