They temporarily disappear from view in amateur telescopes due to their extraordinary thinness. Although the main rings are 300,000 kilometers across, they can be as thin as 10 meters (33 feet) in places. To scale, Saturn's rings are much thinner than a standard sheet of paper. Earth passes through the ring plane on March 23, 2025. NASA Saturn passed opposition on September 8th and is now well placed in the southeastern sky at nightfall in Aquarius. I can still recall the first time I found the planet from my front yard in the winter of 1965. It was situated in almost the same location you'll find it tonight, a few degrees northwest of the "crooked fingertip" asterism formed by the three Psis — Psi 1  (ψ 1 ), Psi 2  (ψ 2 ), and Psi 3  (ψ 3 ) Aquarii. Wish me happy birthday — I'm two Saturn-yea

The supermassive black hole at the center of a massive galaxy has powered a giant pair of plasma jets, spanning 23 million light-years long from tip to tip. That’s almost 10 times the distance between our Milky Way and the Andromeda Galaxy. Astronomers have nicknamed the record-breaking system Porphyrion, after the king of the giants in Greek mythology. And the giant is indeed the king of many: A new catalog of such radio-emitting giant jet pairs tallies more than 11,000 of them, each spanning more than 2.3 million light-years. “Giant jets were known before we started the campaign, but we had no idea that there would turn out to be so many,” says Martin Hardcastle (University of Hertfordshire, UK), coauthor on two associated studies. Porphyrion’s

September could be a prime time to see vibrant auroras, thanks to a quirk of Earth's tilt that leads to more intense geomagnetic activity around the equinox In May, the  most powerful geomagnetic storm  in more than two decades slammed Earth, leading to intense  northern lights  displays as far south as Florida and Mexico. With solar activity continuing to escalate  at record pace , could a similar display be due in September? There's no guarantee, but there are reasons to believe that the few weeks on either side of this month's fall  equinox  (Sept. 22) could see geomagnetic storms more intense than u
