Enchanting new photo from Perseverance Rover on Mars, shows large rounded river rocks piled up in eroded bank in outflow to the delta. Best evidence we've seen yet for really voluminous flooding. These boulder were rounded by rushing water, transported to this pile, cemented and later excavated. What a world!

@MasterNinjaTS Hmmm, but Jupiter itself is an incredibly powerful source of radio waves... Much more powerful than your phone!

@MasterNinjaTS Do you mean "held it in front of Jupiter" ?? If you actually placed it on Jupiter it wouldn't be very bright from Green Bank would it?

Hello! Just got here and I'm checking it out. This is my first "toot". I am interested in science (specialize in space science, planetary exploration, astrobiology but interested in all of it), music (play guitar: rock african, reggae, funk...), politics, nature and humor... among other things!

Here is a picture of my dog Jasper:

@OnNegation Just so you know, it was this toot which made me join Mastadon. I was scrolling through and saw this and thought to myself "OK, people are posting interesting things here." So... Thank you! I know Evan Thompson and I agree his ideas are fascinating.
