New images from the Hubble Space Telescope confirm the identity of a star that went supernova and allow researchers to study the star’s pre-explosion outburst.
From 2017 to 2023, researchers monitored the X-ray outbursts of a particular pulsar; among other findings, the data suggest three different accretion modes for the source.
A new database of models can be used to synthesize spectral lines in the Sun’s photosphere or its poorly understood chromosphere, or to constrain numerical models of the Sun’s atmosphere.
Newly processed images of Neptune’s moon Triton from Voyager 2 improve the calibration and alignment of these images, which are the highest-resolution images of the moon available.

A string of gas clouds stretching for more than 3,000 light-years has been found to contain stars after all; the structure is the most gas-rich stellar system yet known.
Depending on the orbital period of the binary and the mass-loss rate, binary systems can create diverse distributions of gas, including “shell-like” and “cliff-like” arrangements.
