They’re both texting someone right now saying ‘some weird guy next to me is wearing the same thing as me.’
A runaway star, plowing through the depths of space and piling up interstellar material before it, can be seen in this ultraviolet image from NASA’s Galaxy Evolution Explorer. The star, called CW Leo, is hurtling through space at about 204,000 miles per hour (91 kilometers per second), or roughly 265 times the speed of sound on Earth. It is shedding its own atmosphere to form a sooty shell of discarded material. This shell can be seen in the center of this image as a bright circular blob.
The size of the bubble (called the “astrosheath”) has allowed astronomers to estimate that CW Leo has been shedding its atmosphere for about 70,000 years. This is part of the star’s natural life cycle as it runs out of hydrogen fuel and gradually throws off its outer layers to expose its bare, dying core. This core is called a white dwarf, and is the end product of all low-mass stars like our sun. (x)
New track from our band ‘The Multiversal Concrete Fleet’ will be up later this week
