Today on BigBrain, kids and parents explore NASA’s Deep Space Food Challenge winners, new astronaut health research aboard the International Space Station, and two tiny new snail species reported from Montenegro.

Today on BigBrain: NASA’s Astronomy Picture of the Day shows a rare line-of-sight moment with an airplane, the International Space Station, and the Sun. Then we zoom out to see how Earth’s tilted axis helps create seasons. Finally, scientists describe a tiny orange-spotted killifish from Amazon forest pools and explain why its habitat matters.

Today’s BigBrain explores new science stories for curious kids and families: cats may use long-lasting scent chemicals like an ID card, a T. rex tooth offers clues that the dinosaur may have been warm-blooded, and ultra-bright nanoparticles could someday help reveal hidden chemicals in medicine or water.

Today on BigBrain, kids and parents explore a NASA image of a sparkling star-forming region in the Carina Nebula, learn why AI computer vision still struggles with shapes, and discover how protecting Amazon forests can help wildlife and store carbon.

In this BigBrain episode, kids and parents learn about two new ESA Earth-observing satellites, NASA’s Roman Space Telescope switching on its powerful infrared camera, and how careful steering may help Roman work much longer than planned.

In this warm kids’ news episode, we explore three animal science stories: endangered red pandas photographed by trail cameras in Nepal, research into genes that may help mouse-eared bats live surprisingly long lives, and a study suggesting breakfast helps scent-detection dogs avoid false alarms.

In this BigBrain episode, kids learn about a sky event called an occultation, where the Moon can appear to pass in front of Jupiter from some locations. Then we visit a NASA-highlighted museum event about sea level science and meet Surinam toads that use special fingertip lobules to sense prey in murky water.

Today on BigBrain, kids and families explore an enhanced-color NASA portrait of Pluto, meet a newly identified walking shark near Papua New Guinea, and learn why Galápagos green turtles may be less wander-y than many sea turtles.

In this warm kids’ science news episode, we follow ESA and JAXA’s BepiColombo mission as it begins its Mercury arrival phase, explore NASA’s Hubble image of the N44 superbubble, and learn how a NASA high-altitude balloon carried student and researcher experiments above New Mexico.
