In 1977, the detection of a brief radio signal prompted SETI astronomer Jerry Ehman to write a single word in the margin of a computer printout: "Wow!" Nearly fifty years later, the famous Wow! signal continues to capture our imagination... 🧪 🔭 👩‍🔬 🐡

Dr. Tom Esposito focuses on the architecture and evolution of exoplanetary systems and studies the structures of young solar systems through direct imaging of their circumstellar debris disks – rings of dust and ice that trace collisions among orbiting pebbles, boulders, and planetesimals. 🧪

#PPOD: This enhanced-color image from NASA's Juno spacecraft captures the striking cloud bands of Jupiter's southern latitudes. Jupiter is not only the largest planet in the solar system, but it also rotates at the fastest rate, completing a full day in just 10 hours. 🧪 🔭

Close-up of Jupiter's cloud tops showing multiple large oval storms and smaller vortices embedded in layered, swirling pastel bands of turbulent atmosphere against black space.

🚀 At the SETI Institute, we aren’t just looking at the stars—we are actively trying to understand our place among them. Our mission brings together a brilliant, passionate community of researchers, scientists, and innovators. 🧪 🔭 👩‍🔬

Once thought to be little green men (a reference to LGM 1, the first pulsar ever discovered), pulsars can actually do way more for us than simply be some cool space object we observe. In fact, astronomers like Sofia Sheikh use pulsars to measure distance in space and more! buff.ly/tmeFWKt 🧪 🔭 👩‍🔬

#PPOD: Over the Southern Ocean surrounding Antarctica, winds can whip around the globe relatively unimpeded by land. Intrepid sailors termed these southern latitudes the Roaring Forties, Furious Fifties, and Screaming Sixties on account of the strong prevailing winds. 🧪

A sea of white clouds covers this picture, taken by Landsat 8 from Earth orbit. In the bottom left corner is an island covered in snow and labeled Peter I Island. The winds driving the clouds are disrupted by the island, and a chain of four vortexes progresses to the upper right corner.

#PPOD: NASA’s Psyche spacecraft completed its close approach of #Mars on May 15, coming within 4,609 km of the surface. This representative color image features the double-ring crater Huygens and the surrounding heavily cratered southern highlands. Credit: NASA/JPL-Caltech/ASU 🧪 🔭

Representative color image of the large crater Huygens on Mars (upper right). The rest of the surface is also pockmarked with smaller impact craters.

#PPOD: This stunning snapshot, taken with ESO’s Very Large Telescope (VLT), reveals the stars and gas surrounding an invisible giant — a supermassive black hole, located some 27,000 light-years away, at the heart of our Milky Way. 🧪 🔭

Astrophoto of the stars and gas surrounding the black hole at the center of the Milky Way (unseen). The gas clouds are shown in red and wrap about two thirds of the way around the center of the image, from upper left to the middle of the right side.
