NASA Satellites Observe Historic 2026 El Niño

A phenomenon rarer than a solar eclipse and more powerful than any single storm system is unfolding this fall, and NASA is tracking it closely. El Niño is a natural climate pattern that emerges roughly every two to seven years marked by warmer-than-normal water temperatures in parts of the equatorial Pacific. NASA scientists are keeping […]

Chandra Finds Possible Origin of ‘Treble Clef’ Waves

A formation of radio waves looks remarkably like a treble clef in this Oct. 14, 2026, image from NASA’s Chandra X-Ray Observatory. Researchers used Chandra to find that the Treble Clef is likely caused by an outburst from a supermassive black hole, followed by a collision of two galaxy clusters. Read more about this discovery.
