#PPOD: Some of the incredible solar activity was captured last month by spacecraft near the Sun, including these plasma tornadoes. These walls of plasma are higher than the Earth is in diameter. And, of course, all this solar activity has provided us with stunning aurorae. With solar maximum approaching, chances are high that we'll see more incredible views like this one!

Photographer Johannes Holzer used a star tracker to capture the night sky and a Sony A7r in a water-case to get the underwater scenery. Both exposures took 300 seconds. We think you'll agree that the result is beautiful. Credit: Johannes Holzer #PPOD: Please enjoy this amazing shot of the International Space Station passing in front of the Sun. Several solar prominences are also visible. If you look closely, you can also see the Dragon capsule docked to the ISS (inset, upper right).

The Perseid meteor shower peaks this weekend on Saturday night−Sunday morning, August 12−13.

T Also captured were unusual cloud ripples above the pileus cloud. The formation of a rare pileus cloud capping a common cumulus cloud is an indication that the lower cloud is expanding upward and might well develop into a storm. Credit: Jiaqi Sun

@setiinstitute Holy shit.
@setiinstitute Beautiful. How long is the exposure?
@setiinstitute So theoretically, if I could rub millions of inflated balloons together at once I could create lightning?
