Scientists announced that they have discovered signs of water on Mars in a NASA press conference Monday morning, fueling questions about whether life could survive on the red planet. Naturally, jokes flowed on Twitter, including barbs from actors, comedians, writers and YouTube celebrities. Some even made jokes about actor Matt Damon, who plays a stranded astronaut in The Martian, which opens in theaters this weekend. Here is a glimpse at some of the funniest reactions to the out-of-this-world news on Twitter:
Wake me when they find free-flowing vodka on Mars.
PHOTOS: The Most Beautiful Panoramas and Mosaics From Opportunity’s Decade on Mars
Rover tracks disappear toward the horizon like the wake of a ship across the desolate sea of sand between the craters Endurance and Victoria on the Meridiani Plains. NASA— JPL-Caltech / Cornell UniversityThe Mars Rover Spirit took this sublime view of a sunset over the rim of Gusev Crater, about 80 kilometers (50 miles) away. NASA—JPL-Caltech / Texas A&M / CornellA false-color image of Endurance Crater. In this image, tendrils of sand less than 3.3 ft (1 m) high extend from the main dune field toward the rover. Dunes are a common feature across the surface of Mars. Before the rover headed down to the dunes, mission managers first established whether the slippery slope that led to them was firm enough to ensure a successful drive back out of the crater. Otherwise, the dune field would become a sand trap.

Nicknamed "blueberries" by mission scientists, the little pellets are actually hematites, an iron oxide typically formed in standing water—of which Mars once had plenty.NASA—JPL-Caltech / Cornell / USGS / Cathy WeitzSpirit obtained this view of the area called Home Plate while parked atop a formation called Husband Hill. The colors emphasize differences in rock weathering.

The view is presented in false color to make differences in surface materials more visible. A portion of Endeavour Crater's eastern rim, nearly 19 miles (30 km) distant, is visible.NASA—JPL-Caltech / CornellNASA's Spirit rover acquired this false-color image after using its abrasion tool to brush the surfaces of rock targets informally named "Stars" (left) and "Crawfords" (right). Small streaks of dust extend for several centimeters behind the chips and pebbles in the dusty soil.

Opportunity took the image while stuck in the sand ripple dubbed Purgatory for over a month. This panorama (only partly shown here) was named Rub Al Khali after the “Empty Quarter” in the Arabian Desert.NASA—JPL-Caltech / Cornell University
