This is a 30 minute time-lapse and close-up view of the comet captured from my backyard to see how the comet moves in relation to the background stars. It was captured with a RASA 8 and CLS Filter - no calibration frames. | Chuck’s Astrophotography | Facebook

Comet 2I/Borisov is the first confirmed comet to enter our solar system from some unknown place beyond our Sun’s influence. Thanks to observations with NASA’s Hubble Space Telescope and the National Radio Astronomy Observatory’s Atacama Large Millimeter/submillimeter Array (ALMA), astronomers have figured out that 2I/Borisov has an unusual composition. Specifically, it has a higher concentration of carbon monoxide than any comet seen at a similar distance; that is, within about 200 million miles
