Distant and Strange: Orb isn’t just another extrasolar planet

A novel search technique that could ultimately find Earthlike worlds has uncovered an extrasolar planet that is 30 times farther away than any other planet detected and lies closer to its parent star than does any other orb discovered to date.

Model Tracks Storms from the Sun

Teams of astronomers have developed a reliable method for predicting the time it takes for solar storms to arrive at Earth and have gathered observations confirming a model of how the sun's outer atmosphere, or corona, manages to store up enough magnetic energy to induce these upheavals.

Runaway black hole

Observing a black hole and its visible companion star caroming through our galaxy, astronomers have found the best evidence to date that stellar-mass black holes are born during supernova explosions.
