What it is: Geysers of gas and dust on Mars
Where it is: The south polar area of Mars
When it was shared: Jan. 29, 2025
Why it’s so unique: These odd, fan-like functions on the surface area of Mars are geysers of gas and dust near the world’s south pole that show up just in spring on the Red Planet. This image was taken by the Mars Reconnaissance Orbiter (MRO) in 2018 and was reshared by NASA just recently.
Throughout winter season on Mars, co2 ice builds up near the surface area. According to NASA, co2 ice is transparent, and sunshine that survives it is soaked up at the base of the icy layer. As the sun increases greater into the sky and spring starts, co2 ice starts to warm and turn to vapor. That vapor then gets away through weak points in the ice and appears in the kind of geysers. These eruptions often leave dirty, rugged streaks, nicknamed “spiders on Mars.”

Mars has 4 seasons comparable to those in the world. That’s due to the fact that Mars’ orbit spins on an axis slanted by 25.2 degrees (comparable to Earth’s 23.5 degrees), implying various parts of Mars get varying quantities of sunshine as the world orbits the sun. Since Mars takes 687 Earth days to orbit the sun, the seasons last around two times as long as they do on our world.

There’s something else about Mars’ orbit that makes the seasons various. Due to the fact that the world’s orbit of the sun is a little elliptical, there’s a substantial distinction in between Mars’ closest and farthest point to the sun.
According to the European Space AgencyMars is closest to the sun throughout summer season in its southern hemisphere, making that season much shorter and hotter than summertime in the North. Alternatively, winter season in the southern hemisphere happens when Mars takes a trip at its slowest and farthest from the sun, making it longer and cooler than winter season in the North.
This sensational image originates from the High Resolution Imaging Science Experiment electronic camera on the MRO, which introduced on Aug. 12, 2005, and started orbiting Mars on March 12, 2006.
