NASA’s Hubble Space Telescope Finds Dead Stars ‘Polluted with Planet Debris

This is an artist’s impression of a white dwarf (burned-out) star accreting rocky debris left behind by the star’s surviving planetary system. It was observed by Hubble in the Hyades star cluster. At lower right, an asteroid can be seen falling toward a Saturn-like disk of dust that is encircling the dead star. Infalling asteroids pollute the white dwarf’s atmosphere with silicon.

Recognize that the very molecules that make up your body, the atoms that construct the molecules, are traceable to the crucibles that were once the centers of high mass stars that exploded their chemically rich guts into the galaxy, enriching pristine gas clouds with the chemistry of life. So that we are all connected to each other biologically, to the earth chemically and to the rest of the universe atomically. That’s kinda cool! That makes me smile and I actually feel quite large at the end of that. It’s not that we are better than the universe, we are part of the universe. We are in the universe and the universe is in us.

Starburst Galaxy

Messier 82, also known as the Cigar Galaxy, is a starburst galaxy about 12 million light-years away in the constellation Ursa Major. Starburst galaxies undergo extremely high rates of star formation and are thought to represent a particular phase in a galaxy’s evolution. Because of its excessive star birth, M82 is five times brighter than our own Milky Way galaxy.
