We hope you enjoyed yesterday’s Plot Bunnies featuring our Planets named after Gods. This is the beginning of a new project that Dave Mornix and I have planned. Each day will post something funny, weird or strange … but with some fact behind it. You can then run with it and use it for your own inspirational purposes or just read it and do nothing the choice is yours.
Cannibalism is when an animal will eat it’s own kind. Cannibalism of the human kind has made it to the news and it’s still rare. However, something you may not have known maybe cannibalism is in our nature? Our own Milky Way Galaxy is a Cannibal. Part of the Local Group, according to Max-Planck Institute for Astronomy reported in 2010:
Spirals eat dwarfs:
Galactic tendrils shed light on evolution of spiral galaxies
Spiral galaxies grow by swallowing smaller dwarf galaxies. As they are digested, these dwarf galaxies are severely distorted, forming structures such as surreal tendrils and stellar streams that surround their captors.
Around the Milky Way galaxy and in the vicinity of our immediate cosmic neighborhood, known as the “Local Group” of galaxies, traces of spiral galaxies swallowing dwarf galaxies have been known since 1997. But the Local group with its three spiral galaxies and numerous dwarfs is much too small a sample to see whether theoretical predictions of the frequency of such digestive processes match observations. Now, for the first time, a new survey has managed to detect the tell-tale tendrils of galactic digestion beyond the Local Group. An international group of researchers led by David Martínez-Delgado (Max Planck Institute for Astronomy and Instituto de Astrofísica de Canarias) has completed a pilot survey of spiral galaxies at distances of up to 50 million light-years from Earth, discovering the tell-tale signs of spirals eating dwarfs.
Some Local Group Facts:
- The Local Group is a group of galaxies (including the Milky Way Galaxy) it is composed of more than 54 galaxies
- The gravitational center of the Local Group is located somewhere between the Milky Way Galaxy and the Andromeda Galaxy
- The Local Group was introduced by Edwin Hubble, in 1936
- The Andromeda Galaxy is the largest in the group
Food for thought:
Story ideas …
What would it be like if something occurred and accelerated the collisions of these galaxies?
What would it look like to be able to travel far out into space to be able to see the Local Group in all it’s glory?
