Using advanced new simulations, a team of astronomers in the U.S. has developed a promising new theory for how giant, gaseous exoplanets migrate into stiflingly close orbits around their host stars. Led by J. J. Zanazzi at ...
The Earth is surrounded by an invisible barrier that was thought to prevent highly energetic electrons from reaching closer to our planet. But in 2024, Japan's Arase space probe detected these electrons well inside the barrier. ...
