From chandraxray http://status.hackerposse.com/url/16717 on Twitter: NGC 7662 is a planetary nebula located about 4,000 light-years from Earth. The diffuse X-ray light seen with Chandra (pink) is caused by shock waves as a wind from the hot remnant of the star collides with the ejected atmosphere. NGC 7662 is about 0.73 light-years across. http://status.hackerposse.com/ur…
