Winners of the competition captured brand new discoveries out in the depths of space, as well as beautiful images of our solar system neighbors.
New images of Olympus Mons have helped provide answers to a Martian mystery.
NASA is planning to deliver the first samples of Martian material to Earth, which could shed light on the question of whether life existed on the Red Planet.
A variety of strange phenomena have been spotted in the depths of space that look eerily like human objects, or even animals.
The discovery has implications in the search for potential signs of life on the Red Planet, researchers said.
A senior Russian official said that Mars makes money in Russia but sponsors Ukraine and, possibly, its armed forces, "hiding behind humanitarian goals."
Several car windows were smashed while smoke and dust engulfed the surrounding area following the launch.
Comet C/2022 E3 (ZTF), which has already been observed with the naked eye, is zooming away from Earth, perhaps never to return.
Mars will honor women by selling "all-female" M&M's for a limited time.
The planetary parade will likely only be visible until December 31 as Mercury rapidly fades.
The three asteroids range in size, between that of a Boeing-777 and of a 50-story building.
The asteroid, named 2015 RN35, will be traveling at speeds of 13,220 miles per hour as it flies past our planet.
The last full moon of the year coincided with two rare astronomical events that thrilled stargazers and photographers worldwide.
Tonight's full moon will appear in the night sky before Mars passes behind it.
The last full moon of the year will occur at the same time that Mars aligns with the Earth, moon and sun, meaning the Red Planet will be at its brightest.

The research points to recent geothermal activity under the southern Martian ice cap.
Users can experience the desert landscape on Mars using virtual reality technology.
Debris from previous Mars landings and crashes might affect future missions to the red planet.
It's significant because researchers say they can't carry everything out to space, and if they forget a tool on a mission they can't come back to get it.
NASA had said there will be 60 percent favorable weather conditions as the agency tried to launch the historic spacecraft again after previous engine problems.
The device is eventually expected to help humans establish farms for self-sustenance on Mars.
The historic mission's launch was halted following a fuel leak, but it could take place as early as next week.
