What a catch!
This #hubbleclassic image from 2005 shows the Boomerang Nebula, made of two lobes of matter being ejected from one central star.
Astronomers are unsure what causes this nebula's bipolar outflow, but it is believed that the Boomerang Nebula is made of the ejected outer layers from an old red giant star.
Submillimeter radio measurements made in 1995 show the interior of the nebula has a temperature of about one degree Kelvin above absolute zero – with absolute zero equal to nearly -460 degrees Fahrenheit. This puts the inner regions of the Boomerang Nebula among the coldest known places in the universe.
The nebula is about 5,000 light-years away from Earth in the constellation Centaurus.
