This month the journal Astrobiology is publishing a special issue dedicated to the search for…

JPL’s Juno Spacecraft Spots Jupiter’s Great Red Spot, Up Close

This enhanced-color image of Jupiter's Great Red Spot was created by citizen scientist Jason Major using data from the JunoCam imager on NASA's Juno spacecraft. Credit: NASA/JPL-Caltech/SwRI/MSSS/Jason Major Images of Jupiter’s Great Red Spot reveal…

Three Caltech Researchers Receive $10 Million Funding Promise to Launch Cell Research Center

MEMOIR enables the histories of cells to be recorded in their genomes and then read out using microscopy. Here, MEMOIR cells were variably activated, as seen by the bright cyan nuclear fluorescence in some cells.…

This true color mosaic of Jupiter was constructed from images taken by the narrow angle camera onboard NASA's Cassini spacecraft on December 29, 2000, during…

Caltech Researchers Investigate Novel Viral Vectors Deliver Useful Cargo to Neurons Throughout the Brain and Body

The researchers used the engineered viral vector AAV-PHP.S to label neurons lining the digestive tract with a cocktail of three distinct fluorescent proteins. Due to…

Why No One Under 20 Has Experienced a Day Without JPL on Mars

This portion of a classic 1997 panorama from the IMP camera on the mast of NASA's Mars Pathfinder lander includes "Twin Peaks" on the horizon, and the Sojourner rover next to a rock called "Yogi." Image credit: NASA/JPL (Click to enlarge) As the Mars Pathfinder spacecraft approached its destination on July 4, 1997, no NASA mission had successfully reached the Red Planet in more than 20 years. Even the mission team anxiously awaiting confirmation that the spacecraft survived its innovative, bouncy landing could not anticipate the magnitude of the pivot about to shape the Space Age. In the 20 years…
