WISE Sees Dying Stars in Infrared: NGC 1514

Distance: 800 light years
Constellation: Taurus
The object is actually a pair of stars — one star is a dying giant somewhat heavier and hotter than our sun, and the other was an even larger star that has now contracted into a dense body called a white dwarf.
As the giant star ages, it sheds some its outer layers of material to form a large bubble around the two stars. Jets of material from the white dwarf are thought to have smashed into this bubble wall.
The areas where the jets hit the cavity walls appear as orange rings in the WISE image. This is because dust in the rings is being heated and glows with infrared light that WISE detects.
The green cloud seen in the WISE view is an inner shell of previously shed material. In the visible image, this shell is seen in bright, light blues. An outer shell can also be seen in the visible image in more translucent shades of blue. This outer shell is too faint to be seen by WISE.

Every single word of this.

This is honestly such real shit. Every word of it. Second to last frame hits a lot (I really hardly ever considered the possibility that there was such thing as not-spectatoring).

Worth a reblog…

This is important. Go back and read it.

This is a quadruple Saturn moon transit snapped by Hubble in 2009.

The giant orange moon Titan — larger than the planet Mercury — can be seen at upper right. The white icy moons that are much closer to Saturn, hence much closer to the ring plane in this view, are, from left to right: Enceladus, Dione, and Mimas.
