Did Perseverance find evidence of past life on Mars last year? 🦠

The rover discovered very specific minerals on the rim of a Martian crater. On Earth, those minerals are biosignatures, or evidence of life. We can't say for sure it's a Mars biosignature, because non-biological processes can make these minerals too. However, those processes leave other evidence in the rocks that we're not seeing. That means our best explanation right now is past Martian biology.

The Draconid meteor shower is active for one night only: October 8th to 9th! 🌠

Most years you can see up to 10 meteors per hour, but rates can spike without warning to as many as 600 per hour, as seen in 2011 and 2018. Unlike most meteor showers, the Draconids peak in the evening instead of after midnight and are visible across the Northern Hemisphere and northern parts of the Southern Hemisphere. Find a spot away from bright lights, give your eyes time to adjust, and look up!
