A Cosmic Puzzle: Phosphine Found in One Brown Dwarf, Missing in Others

The explosive compound forms naturally in the atmospheres of Jupiter and Saturn, but on Earth it is also a byproduct of anaerobic life.

The three components of this system are shown scaled to their relative sizes. Image credit: Adam Burgasser, UCSD.

Astronomers Investigate Complex Heart of a Cosmic Butterfly

The James Webb Space Telescope offers a new view of a planetary nebula located about 3,400 light-years away in the constellation Scorpius.

The complicated structure at the centre of the Butterfly Nebula, NGC 6302. There is a bright source at the centre that is surrounded by greenish nebulosity and several looping lines in cream, orange and pink. One of these lines appears to form a ring oriented vertically and nearly edge-on around the bright source at the centre. Other lines trace out a figure eight shape. Moving outward from these complex lines and green nebulosity, there is a section of red light on either side of the object.
