Something abnormal is cruising toward us. Something little and cold and uncommonly quick. Nobody knows where it originated from, or where it is going. However, it’s not from around here. This is an interstellar comet – an old chunk of ice and gas and residue, framed on the solidified edges of a far off star, which some fortunate characteristic of gravity has hurled into our way. To space experts, the comet is a consideration bundle from the universe – a bit of a spot they will always be unable to visit, a key to every one of the universes they can’t legitimately watch.
It is just the second interstellar intruder researchers have found in our nearby planetary group. Also, it’s the first they’ve had the option to get a decent take a gander at. By following the comet’s development, estimating its sythesis and checking its conduct, analysts are looking for pieces of information about the spot it originated from and the space it crossed to arrive. They have just discovered a carbon-based particle and potentially water – two natural synthetic compounds in such an outsider item.
As the Sun sinks behind the Tennessee mountains, and stars wink into see, cosmologist Doug Durig ascends onto the housetop of his observatory, controls up his three telescopes and points them skyward.
Consistently, the comet becomes greater and more brilliant in the sky, ousting surges of gas and residue that may present pieces of information to its history. On Dec. 8, it will make its closest way to deal with Earth, offering scientists a very close look before it zooms once more into the solidifying, featureless void.
