Comet McNaught.

“The images we see can only be “beautiful” or “real-looking” because they have been heavily processed, either by neural machinery or by code (in which case, both), operating below our threshold of consciousness. In the case of the software, this processing relies on norms and aesthetic judgments on the part of software engineers, so they are also unacknowledged collaborators in the image-making. There’s no such thing as a natural image; perhaps, too, there’s nothing especially artificial about the camera.” art in the age of machine intelligence — Artists and Machine Intelligence — Medium https://medium.com/artists-and-machine-intelligence/what-is-ami-ccd936394a83

NGC 1291 This 12 billion year old barred galaxy is located in the Eridanus constellation. Young stars dot the outskirts of the galaxy (shown in red) and older stars reside in the center (shown in blue).

on Nov. 28, 2013, comet ISON will fly through the sun’s atmosphere little more than a million km from the stellar surface. If the comet survives without breaking up it could emerge glowing as brightly as the Moon, visible near the sun in broad daylight.

Kindly share this, so that no one could miss that event!

ESA Rosetta has just released this marvelous video clip of 3 images,18 minutes apart, of a spectacular outburst on Comet 67P. This is what happens when comets, in their orbits around the Sun, start getting close enough for the ices they are made of to warm, turn to vapor, and erupt from below the dark, encrusted surface to form a jet, often entraining icy and rocky particles in the process.

It is the growing number and strength of such jets that form as the comet nears the Sun that produce the magnificent tails that can stretch long and mythical across the night skies of Earth.

And here, you are witnessing the process from its beginnings.

Hosanna to Comet 67P!
