It's not time to get out the sleds and shovels in the United States, but all the way over on Mars, snow may be falling on the south pole.
There appears to be snow falling on the Red Planet that is not made of water, however. This is frozen carbon dioxide, which can only exist at extremely low temperatures - namely, about -193 degrees Fahrenheit.
New data to be published in the Journal of Geophysical Research explores evidence for carbon dioxide snowfalls that come from clouds around the Martian south pole during the winter. The data comes from the Mars Reconnaissance Orbiter.
This is the only example of carbon-dioxide snow falling that we know about in the solar system, NASA said Tuesday.
We know about water-ice snow on Mars too from NASA's Phoenix Lander, which observed it in 2008.
A fireball thought to be an asteroid or comet hitting the surface of Jupiter was captured by two amateur astronomers early Monday, spaceweather.com reports.
“The impact was observed by Dan Peterson visually this morning,” Hall wrote, crediting another space enthusiast with making the initial observation and posting what he saw online.
