First radio waves from exoplanet
Our top story today is that astronomers say they’ve detected radio waves from a planet outside our solar system for the very first time.[12] The planet is about 63 light-years away, and the signal they’ve picked up is linked to its magnetic field rather than to any kind of intelligent broadcast.[12] In other words, this is not evidence of alien life, but it is a milestone in how we study distant worlds.
What makes this detection stand out is the strength of that magnetic field. Researchers estimate that it’s at least 200 times stronger than Jupiter’s, which already has an impressive magnetosphere of its own.[12] A field that intense can have big consequences for a planet’s atmosphere and its space environment, shaping how charged particles move around it and how the planet interacts with its host star.[12] By catching radio waves produced by that magnetism, astronomers gain a new way to probe exoplanet properties that are otherwise very hard to measure.
The team behind the discovery emphasizes that more observations are planned, both to confirm exactly how the sign

Today's topics:
First radio waves from exoplanet - Astronomers have detected radio waves from a planet about 63 light-years away, marking the first confirmed radio signal directly linked to an exoplanet’s enormous magnetic field. Keywords: exoplanet, radio waves, magnetic field, 63 light-years.[12]
Early universe metals and neutron stars - New observations show heavy elements escaping from some of the universe’s first galaxies, while a newly characterized double neutron star system has the lowest total mass ever measured, sharpening tests of general relativity and dense matter. Keywords: JWST, early universe, metals, neutron stars, general relativity.[13][2]
Daytime auroras captured from space - The SMILE spacecraft has produced a striking ultraviolet view of Earth’s auroral oval, revealing northern lights shimmering on both the night and day sides of the planet and offering a new window into space weather. Keywords: SMILE mission, auroras, magnetosphere, solar wind.[17]
AI hardware rides to orbit - A prototype satellite carrying Google’s Tensor Processing Units has reached orbit on a recent rideshare mission, kicking off Project Suncatcher’s effort to test AI hardware in the harsh space environment and explore future in-orbit computing. Keywords: Google, AI chips, satellite, Project Suncatcher, Tensor Processing Units.[8][18]
SpaceX tripleheader and Mars rover - SpaceX has just completed three launches in under 13 hours capped by a classified NROL-97 mission on Falcon Heavy, while ESA and Airbus are testing the ExoMars rover prototype ‘Charlie’ in Spain’s Tabernas desert ahead of a future life-hunting mission to Mars. Keywords: SpaceX, Falcon Heavy, NROL-97, ExoMars, Mars rover tests.[9][1][16]
