Update Oct. 13 11:40 a.m. EDT: The original winner of the Sir Patrick Moore Prize for Best Newcomer was deemed ineligible, and a new winner has been named. This piece has been updated to reflect the new winner's entry.

A flare in last year's brightest comet topped entries in an astronomy photographer contest.

Gas spewing off the tail of Comet Leonard won the top prize of the Royal Observatory Greenwich's Astronomy Photographer of the Year contest for 2022. Comet Leonard broke into pieces early this year after rounding the sun, but not before producing a long tail easily visible in amateur photos.

The winner, Gerald Rhemann, will be featured among the top category entrants at the National Maritime Museum in Greenwich, U.K. in an exhibit opening Saturday (Sept. 17).

In pictures: Amazing photos of Comet Leonard in the night sky

"Rhemann's astonishing image of Comet Leonard, a long-period comet first identified in January 2021, was captured by the Austrian photographer in Namibia on Christmas Day," the observatory stated, adding the decision to award Rhemann the top prize was unanimous. 

"This award is one of the highlights of my astrophotography work. All the effort that went into making this image a success was worth it," added Rhemann in the same statement.

The contest received more than 3,000 entries from 67 countries and you can see the top selectees in each category below.
