Comet Flight

"This shows that 2I/Borisov is not a completely alien object, and confirms some similarity with our 'normal' comets, so the processes that shaped it are comparable to the way our own comets formed," said Martin Cordiner, an astrobiologist working at NASA's Goddard Space Flight Center.

For the first time ever, scientists have detected ethyl alcohol - the kind that makes booze - in emissions from a comet. Comet Lovejoy, it turns out, is quite aptly named: The ball of ice and dust, which releases the equivalent of about 500 bottles of wine each second during its peak activity, also emits a type of sugar.

A German travel agency is selling tickets for a flight to give 88 astronomy buffs a close-up view of one of two rare comets expected to pass Earth this year.

How much would you pay to emulate astronauts as they float weightlessly in space?
