But I laughed when I saw this part because I KNEW he was going to intentionally get drunk.

The Jellyfish Nebula

The Jellyfish Nebula (also known as IC 443 and Sharpless 248 (Sh2-248)) is a galactic supernova remnant in the constellation Gemini. On the plan of the sky, it is located near the star Eta Geminorum. Its distance is roughly 5,000 light years from Earth. The Jellyfish Nebula may be the remains of a supernova that occurred 3,000+ years ago. The same supernova event likely created the neutron star CXOU J061705.3+222127, the collapsed remnant of the stellar core. The Jellyfish Nebula is one of the best-studied cases of supernova remnants interacting with surrounding molecular clouds.

Jupiter’s moon Io, photographed by Voyager 2, 10 July 1979.

The end of this blog’s Io-thon follows on from yesterday’s post. The photos used in this gif were taken with longer exposures than yesterday’s, so there is a better contrast between Io and the background. Two volcanic eruptions are clearly visible in the top-left: I think that they are from Amirani and Maui. There’s also an eruption on the right-hand side, but as its only lit by reflected light from Jupiter, it requires a lot of brightening to see (NASA’s photojournal shows it here).

You can also see a volcano in the south, tall enough to stay in sunlight even as the surrounding areas fall into darkness.

Yesterday I mentioned the bright spot glinting near the equator. I asked Jason Perry (who used to write an Io blog) about it on Twitter and he said that it “looks like specular reflection off of glassy, cooled lava near Hi’iaka Patera.” So there you go.
