This image is the Boomerang Nebula, a product of ALMA and Hubble. The Boomerang is 5,000 light-years away in the constellation Centaurus. Click the image above to see the Hubble image without the ALMA data, you will also see why it also has the name of the Bow Tie Nebula.
The Boomerang is a protoplanetary nebula, a confusing term because it does not mean it is forming planets, it’s between the (asymptotic) giant phase and the planetary nebula phase. The cool thing about the Boomerang is not just cool it is cold. It is the coldest place we know of, 1 degree Kelvin and that’s -272.15 C / -457.87 F, the atoms are just barely moving!
I also can’t help thinking I saw an episode of Star Trek with a creature that looks a lot like the ALMA addition.
