Chandra Spots Distant Baby Planet Losing Its Atmosphere Under Intense X-ray Assault

By
NASA’s Chandra X-ray Observatory has captured a rare glimpse of TOI 1227 b, a young, Jupiter-sized exoplanet losing its atmosphere under intense stellar radiation. Just 8 million years old, the planet is shrinking rapidly as X-rays strip away its mass. Scientists warn it may become a barren rocky core in about a billion years.

NASA Spots Plankton Swarms from Space to Help Save North Atlantic Right Whales

By
North Atlantic Right Whales are one of the world’s most endangered mammals. They face threats from fishing gear entanglement and ship collisions. Scientists are now using NASA satellite data to track the whales’ key food source, the red coloured plankton Calanus finmarchicus, in the Gulf of Maine. By identifying swarms of this copepod via its natural pigment, researchers hope to better understand whale migration. With new technology like the PACE satellite, future ocean monitoring could dramatically enhance whale conservation efforts. from Gadgets 360 https://ift.tt/VMO0Agv
