In 1990, the field of astronomy was forever changed with the launch of the Hubble Space Telescope. While it was not the first space observatory, its unprecedented resolution and versatility allowed for the deepest and most detailed images of the Universe ever taken. The latest image to be released by the mission features the spiral galaxy NGC 691, which was captured in amazing detail by Hubble’s Wide Field Camera 3 (WFC3).Continue reading “Time to Update Your Desktop Wallpaper With This Perfect Spiral Galaxy: NGC 691”

And for good measure, thrown in on this story are cannibalism and even zombies. The result of the meet-up? Babies. Baby stars, that is, and the individual galaxies in this tale ended up, seemingly, living together happily-ever-after. The Hubble Space Telescope’s Wide Field Camera 3 (WFC3) captured images of NGC 4150, an aging elliptical galaxy, and at the core of the galaxy was some vigorous star birth. The star-making days of this galaxy should have ended long ago, but here was active star birth taking place.
