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.
A potential supermassive black hole so early in the universe’s history would likely have to have been seeded by a black hole 10,000 to 100,000 times the mass of the Sun.
New JWST observations of the famous protoplanetary-disk-hosting protostar HL Tau reveal known disk features in greater detail and help to place limits on possible planets.
