Astronomers have, for the first time, observed the birth of a magnetar, an extremely magnetic, rapidly spinning type of neutron star. The breakthrough confirms that these exotic objects can power some of the brightest stellar explosions ever seen. The discovery also validates a theory first proposed 16 years ago by a UC Berkeley physicist and…
In “Endgame,” the 2001 series finale of Star Trek: Voyager, Kathryn Janeway traveled back in time to an early 25th-century version she deemed undesirable. The ethical implications of this are massive, and we can’t get too mad at Janeway for this, because, in theory, that version of her no longer exists. But did Janeway wipe…
In 2024, astronomers detected a rocky exoplanet, GJ 3378b, orbiting a red dwarf sun just 25 light-years from Earth in the direction of the northern constellation Camelopardalis. Based on radial velocity measurements, the discovery team estimated that this planet is 2.3 times as massive as Earth – making it a “Super Earth.” Thanks to revised…
Back to Article List Everyone can watch a small moon skim Saturn’s northern pole, while advanced imagers may catch its shadow on the cloud tops. Tenth-magnitude Dione passes north of Saturn twice this month, accompanied by its shadow. The latter can only be detected via imaging. Also shown are several fellow moons: Rhea and Tethys…
