#PPOD: This stunning photograph captures the most violent moment during an eruption of the Calbuco volcano in Chile. Volcanic lightning occurs in the plumes of eruptions when volcanic ash particles collide, generating static electricity. Additionally, water vapor in the plume condenses and freezes as it rises, adding ice to the mix. And voila! The eventual electrical discharge causes lightning.

@setiinstitute So theoretically, if I could rub millions of inflated balloons together at once I could create lightning?

#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! Credit: NASA

A close-up view of plasma tornadoes seen in profile off the limn of the Sun, taken in non-visible light from a time-lapse video collected by a NASA spacecraft. The dark swirls of a sunspot can be seen on the solar surface below the tornadoes.

#PPOD: Taken in 2016, this stunning composite photo shows the Milky Way stretching above the Isar River in Germany as well as the stunning landscape beneath the river's surface. 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

A composite image featuring the Milky Way above a mountain ridge in the top third.. Beneath that stretch the green bank of the Isar River in Germany, and then the surface of the river. The second piece of the photograph reveals the jagged and eerily lit underwater landscape of the river.

#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). Credit & Copyright: Mehmet Ergün

A zoomed in photography of a portion of the Sun, taken with the International Space Station pass between the star and Earth. The artist's signature is at the bottom. Several large solar prominences are seen on the Sun's limb near the top. An inset in the top right corner points out where the SpaceX Dragon capsule is.

A Banner Year for the Perseid Meteor Shower

It’s August and that means one of the year’s most beloved celestial events will grace the skies. The Perseid meteor shower peaks this weekend on Saturday night−Sunday morning, August 12−13.

#PPOD: Pictured, behind this darker cloud, is a pileus iridescent cloud, a group of water droplets that have a uniformly similar size and so together diffract different colors of sunlight by different amounts. 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

Blue sky with a dark cumulus cloud blooming up above some trees. On top of the cumulus cloud is a rainbow curving in a circle around the top, caused by light reflected on water droplets.
