: Comet from 8 Kilometers

In October 2014, Rosetta ventured to within 8 kilometers of the surface of comet Churyumov-Gerasimenko -- lower than the cruising altitude of a passenger plane -- to capture this image of smooth plains and steep cliffs with its OSIRIS science camera.

All of life, from simplest to most complex, contains five information-passing compounds that allow the genetic code to work. These nitrogen-based compounds, called nucleobases, are found in all the the DNA and RNA that provide the instructions to build and operate every living thing on Earth. H

: Ingenuity Spots Percy's Stuff

This remarkable image was taken by the Ingenuity helicopter on April 20, 2022, during the latest flight, number 26. Ingenuity actually flew over the backshell and parachute that took it and the Perseverance rover safely through the martian atmosphere during their descent.

Next : Making SETI More COSMIC
TODAY, Apr 21, 2022, 2:30 pm PDT / 5:30 pm EDT

COSMIC SETI took a big step towards using the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) for 24/7 SETI observations. Fiber optic amplifiers and splitters are now installed for all 27 VLA antennas, giving COSMIC access to a complete and independent copy of the data streams from the entire VLA. Once the digital backend comes online, SETI observations will be possible 24/7 at the VLA! Learn more about COSMIC with Project Scientist Cherry Ng and Postdoctoral Research Fellow Savin Shynu Varghese.

The Commensal Open-Source Multimode Interferometer Cluster Search for Extraterrestrial Intelligence (COSMIC SETI) is a collaboration between the SETI Institute and the National Radio Astronomy Observatory (NRAO), which operates the VLA, to bring a state-of-the-art search for extraterrestrial intelligence to the VLA for the first time. As the VLA conducts observations, COSMIC will enable SETI Institute scientists to access that data to analyze for evidence of technosignatures, signs of technology not caused by natural phenomena.

: An Old Friend

The approximately 15-by-8 kilometer, peanut-shaped nucleus of Halley's Comet, imaged by ESA's Giotto spacecraft 36 years ago in March 1986 from a distance of about 2,000 km. 1P/Halley won't return to the inner Solar System again until 2061.

: Kodiak Butte

The Kodiak Butte is coming into focus as the Perseverance rover comes closer to the delta at Jezero crater on Mars. Kodiak is part of the ancient delta deposited more than three billion years ago. This is a mosaic of two right navigation camera (NavCam) images, color-corrected, balanced, and sharpened.

: Jupiter's Great Red Spot

This perspective of Jupiter, taken by JunoCam onboard NASA's Juno spacecraft, captures the notable Great Red Spot, as well as a massive storm called Oval BA. The storm reached its current size when three smaller spots collided and merged in the year 2000.

Big Picture Science Radio Show: The Latest Buzz

Is your windshield accumulating less bug splatter? Insects, the most numerous animals on Earth, are becoming scarcer, and that’s not good news. They’re essential, and not just for their service as pollinators. We ask what’s causing the decrease in insect populations, and how can it be reversed. Also, the story of how California’s early citrus crops came under attack – a problem that was solved by turning Nature on itself. And how chimpanzee “doctors” use insects to treat wounds. We investigate the small and the many on “The Latest Buzz.”
