Bedtime Astronomy

Astronomers have discovered three sudden rotation changes, or glitches, in the young neutron star PSR J1637−4642.

After more than a decade of apparent stability, observations from the Murriyang radio telescope revealed these unexpected speed-ups, offering new clues about superfluid matter hidden inside neutron stars. The star’s gradual recovery could help scientists understand how matter behaves under the most extreme conditions in the universe.

A bold mission concept could give humanity its first extended rendezvous with Halley’s Comet during its 2061 return.

Using Hall-effect thrusters and gravity assists from Jupiter and Saturn, a spacecraft launched in 2036 or 2037 could arrive early and study the comet for months as it approaches the Sun. The mission could reveal unprecedented details about Halley’s surface, nucleus, and transformation.

Astronomers using James Webb and Hubble may have finally solved the mystery of GRB 061201, a gamma-ray burst that has puzzled scientists since 2006.

Once considered “hostless,” the explosion now appears to have originated in a distant, faint galaxy, potentially resolving long-standing contradictions about its distance and physical properties. A final spectroscopic confirmation could close the case.
