More Dark Star Candidates Found in JWST Data

A growing list of dark star candidates could help explain why some early galaxies were so big, so early in the universe.

The background shows the blackness of space, dotted with colorful stars and galaxies. In a pullout box at the top left, an arrow points to a fuzzy red blob shaped like a jelly bean. A label reads JADES-GS-z14-0.

So What Should We Call This – a Grue Jay?

The rare hybrid offspring of a blue jay and a green jay is likely a result of weather-related shifts in the range of two species.

Three birds are shown. On the left is a blue jay, which is primarily blue with some patches of white on wing tips, around the face and on the chest. On the right is a green jay, which is primarily green with a lighter colored chest and a mix of blue and black patches on the face. In the center is a hybrid bird, which is primarily blue and resembles a blue jay, but with a larger area of black on the face, more akin to a green jay.

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.
