Rolls-Royce Space Reactor, Close Call in Orbit, Webb’s Back

Webb is fully operational again, Rolls-Royce is building a nuclear reactor for the Moon, and the space debris worst-case scenario almost happened. James Webb is Back Last week was tough for James Webb Space Telescope news when we learned that NASA had taken the Near Infrared Imager and Slitless Spectrograph (NIRISS) instrument offline on January 15th. The instrument was experiencing ...

Willis (CfA+ISU); ESA/Herschel; NASA/JPL-Caltech/ Spitzer; CTIO/NOAO/AURA/NSF Over over 50% of high mass stars reside in multiple star systems. But due to their complex orbital interactions, physicists have a difficult time understanding just how stable and long-lived these ...

Astronomers use Earthquakes to Understand Glitches on Neutron Stars

Simulation of a possible quadrupole magnetic field configuration for a pulsar with hot spots in only the southern hemisphere. Credits: NASA’s Goddard Space Flight Center A team of astronomers have used a model of earthquakes to understand glitches in the timing of pulsars. Their results suggest that pulsars may have interiors that are far stranger than can be imagined. Pulsars ...

How Can We Know if We’re Looking at Habitable exo-Earths or Hellish exo-Venuses?

The differences between Earth and Venus are obvious to us. One is radiant with life and adorned with glittering seas, and the other is a scorching, glowering hellhole, its volcanic surface shrouded by thick clouds and visible only with radar. But the difference wasn’t always clear. In fact, we used to call Venus Earth’s sister planet. Can astronomers tell exo-Earths ...

This Binary System is Destined to Become a Kilonova

Kilonovae are extraordinarily rare. Astronomers think there are only about 10 of them in the Milky Way. But they’re extraordinarily powerful and produce heavy elements like uranium, thorium, and gold. Usually, astronomers spot them after they’ve merged and emitted powerful gamma-ray bursts (GRBs.) But astronomers using the SMARTS telescope say they’ve spotted a kilonova progenitor for the first time. A ...
