#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

#PPOD: Red Sprites over New Zealand

Taken at Lake Wanaka, New Zealand, this beautiful image of the Milky Way's core included a surprise guest star - red sprites! These large-scale electrical discharges occur at about 50-90 km in altitude, in the Earth's mesosphere.

#PPOD: This stunning photo was taken by the High Resolution Stereo Camera (HRSC) onboard the ESA's Mars Express spacecraft. Phobos is the larger and closer of Mars's two moons, the other being Deimos. One hypothesis of their origin involves the possible capture of primitive asteroids. Unfortunately, Phobos is being pulled apart and closer by Mars's tidal forces and gravity. Credit: ESA/DLR/FUBerlin/ @andrealuck CC BY (https://www.flickr.com/photos/192271236@N03/53635851891/)

#PPOD: What may look like a strangely nearby galaxy is actually a normal rocket's exhaust plume -- but unusually backlit. Like noctilucent clouds, the plume's brightness is caused by the Twilight Effect, where an object is high enough to be illuminated by the twilight Sun, even when the observer on the ground experiences the darkness of night. The spiral shape is caused by the Falcon rocket reorienting to release satellites in different directions. Credit: Seung Hye Yang

#PPOD: This is neither an impact crater nor a volcano. It is a perfect circular intrusion, about 10km in diameter with a topographic ridge up to 600m high. The Kondyor Massif is located in Eastern Siberia, Russia, north of the city of Khabarovsk. It is a rare form of igneous intrusion called alkaline-ultrabasic massif and it is full of rare minerals. The river flowing out of it forms placer mineral deposits. Credit: NASA/GSFC/METI/ERSDAC/JAROS, and U.S./Japan ASTER Science Team

#PPOD: Happy Valentine's Day!

“Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives.” - Carl Sagan

This image was taken by the Voyager 1 spacecraft on 14 February at Sagan’s suggestion. Voyager was about 6.4 billion kilometers from our tiny dot of a world and heading out of our solar system.

#PPOD: NASA's Voyager 1 probe launched in 1977 and is now the most distant human-made object from Earth, traveling through interstellar space. Recently, NASA engineers had to figure out why the probe was suddenly sending unreadable data. After nearly six months of analysis and re-programming, they got Voyager correctly transmitting again. Truly a feat of human ingenuity. Credit: Dave Granlund

The permafrost is thawing, luring bacteria that will feast on these carbon-rich layers and produce two greenhouse gases, carbon dioxide and methane. How serious is this potential accelerator of climate change? It’s “De-Permafrosting” on Big Picture Science.

#PPOD: Beautiful Jupiter

The Juno mission's JunoCam has taken some lovely images in seven years at the gas giant, including this one of Jupiter's "eye" captured early on during Perijove 09. The key to these amazing pictures, however, is in the citizen scientists who process them. Learn more: https://www.missionjuno.swri.edu/junocam/processing

Research Experience for Undergraduates (REU) program applications are due Feb. 1, 2024!

We invite highly motivated students who are interested in research related to
astronomy, astrobiology, and planetary science to apply. You will work with
scientists at the SETI Institute and NASA Ames Research Center. Research topics
span the field of astrobiology, from microbiology to planetary geology to
observational astronomy.

Taken with NIRCam (Near-Infrared Camera), the picture shows the planet and its rings in new clarity. The planet’s seasonal north polar cap gleams in a bright white, and Webb’s exquisite sensitivity resolves Uranus’ dim inner and outer rings, including the Zeta ring—the extremely faint and diffuse ring closest to the planet.

PRESS RELEASE: https://www.seti.org/press-release/asteroid-impacted-near-berlin-identified-rare-aubrite
Asteroid that impacted near Berlin identified as a rare Aubrite

The official classification now aligns with what many suspected from merely looking at the images of the strange meteorites that fell near Berlin on January 21, 2024. They belong to a rare group called “aubrites”.

“They were devilishly difficult to find because, from a distance, they look like other rocks on Earth,” said SETI Institute meteor astronomer Dr. Peter Jenniskens.

#PPOD: On June 25, NASA’s #JWST turned to famed ringed world #Saturn for its first near-infrared observations of the planet. The initial imagery from JWST's NIRCam (Near-Infrared Camera) is already fascinating researchers. Saturn itself appears extremely dark at this infrared wavelength observed by the telescope, as methane gas absorbs almost all of the sunlight falling on the atmosphere. However, the icy rings stay relatively bright. Credit: NASA/ESA/CSA/STScI/Andrea Luck
