The Hubble Space Telescope has captured the best pictures yet of our newest interstellar visitor.
This comet from outside our solar system is zooming by at a blistering 110,000 mph (177,000 kph). Hubble caught some glam shots over the weekend from a distance of 260 million miles (420 million kilometers). The photos were released Wednesday.
It's the second known interstellar visitor to swoop through our backyard. An amateur astronomer from Crimea, Gennady Borisov, discovered the comet in August, two years after the first alien guest, a cigar-shaped rock, popped up.
Polish astronomers using ground telescopes, meanwhile, say Comet 2I/Borisov looks to be reddish with a nucleus about 1 mile (2 kilometers) across.
The comet will make its closest approach to the sun in December before heading back toward interstellar space.
