APOD 4.3

This is a view of the emission nebula IC 410 in false color. The two clouds of dust and gas in the top left, a part of the "cosmic pond," are the tadpoles.The nebula itself actually surrounds a cluster of stars, NGC 1893, which energizes the glowing gas. The reason for the tadpole shape of the clouds is that they were "sculpted" so to speak by the wind and radiation from the stars. IC 410 lies approximately 12,000 light years away, by the constellation Auriga.

Zooniverse

On Zooniverse I'm doing MoonZoo. I basically just find craters, mounds, boulders or anything irregular to label. So far I haven't seen anything irregular at all, and if I see anything, it's usually just mounds.

APOD 4.2

THIS IS SO COOL. I realize that it's only an artist's rendition, because we have never actually been on Titan's surface, but this image of it is so neat. I chose this picture because it's so neat to think that there's weather on other planets/moons, not just Earth. However, there are major differences, obviously, between our storms and theirs. Since the temperature of Titan is consistently about -290 degrees Farenheit, the storms, cycle of evaporation, cloud formation, and rain, is not water but liquid methane. Thunderstorms like this are seasonal on Titan's surface, more along the equatorial regions. However, the lightning drawn in this picture is not confirmed, just theorized. It is thought that it could exist due to the thick, nitrogen-rich atmosphere.
