Geomagnetic Storms Bring Satellites Down Faster
When the Sun rages and storms in Earth's direction, it changes our planet's atmosphere. The atmosphere puffs up, meaning satellites in Low-Earth Orbit (LEO) meet more resistance. This resistance creates orbital decay, dragging satellites to lower altitudes. One researcher says we can change the design of satellites to decrease their susceptibility.
The Galactic Center Struggles to Form Massive Stars
Gas clouds in the Milky Way's Galactic Center contain copious amounts of star-forming gas. But for some reason, few massive stars form there, even though similar gas clouds elsewhere in the galaxy easily form massive stars. The clouds also form fewer stars overall. Are they a new type of molecular cloud?
At Cosmic Noon, this Black Hole Was the Life of the Party
About 3 billion years after the Big Bang, star formation exploded across the cosmos. During the era dubbed "cosmic noon.” It was also when galaxies and supermassive black holes were growing faster than at any other time in the history of the universe. Now astronomers have discovered a monster from this frenzied period: a supermassive black hole unleashing jets that stretch over 300,000 light-years into space, revealing the sheer violence of its feeding frenzy.
