A big solar storm could fry the internet, but at least space weather forecasts would give us a day or two to prepare. Or maybe not, because physicists have just discovered a new kind of solar storm that strikes without notice Space 18 May 2022 By Stuart Clark Shutterstock/Color4260TROUBLE brewed on 30 January 2022, although…
Home References Science & Astronomy Solar flares release huge amounts of energy. (Image credit: cokada via Getty Images) Solar flares are large explosions from the surface of the sun that emit intense bursts of electromagnetic radiation. The intensity of the explosion determines what classification the flare belongs to. The most powerful are X-class flares, followed…

In a new paper in the Astrophysical Journal, a duo of astronomers from the Kavli Institute for Particle Astrophysics and Cosmology at Stanford University described a way to manipulate solar gravitational lensing to view extrasolar planets. By positioning a space telescope, the Sun, and an exoplanet in a line with the Sun in the middle,…
