A close-up of a star dominates the left side of the image. Its surface glows intensely in various shades of orange, showing irregular structures like darker spots. Delicate, glowing plasma filaments arc outward from the Sun's surface. On the right side of the image, a small rocky planet is visible, its reddish-brown surface marked with dark, mottled patterns. The background is black, dotted with a few white star-like points.

Black hole’s business-as-usual in the earliest universe highlights galaxy evolution problem

Using the space telescope JWST, astronomers have examined one of the most distant known black holes in the universe. Their observations provide a glimpse of the growth of black holes in the early universe, less than a billion years after the Big Bang. Surprisingly, the early black hole in question seems to be “feeding” in much the same manner as its more recent kin. Astronomers have been struggling for a while now to explain how the earliest black holes gained their considerable masses. The new results all but rule out unusually efficient feeding mechanisms at early times as a possible solution. The results have been published in the journal Nature Astronomy.

Planet-forming disks around very low-mass stars are different

JWST discovers a large variety of carbon-rich gases that serve as ingredients for future planets around a very low-mass star more

On the right, in the foreground, is a primarily blue planet with white areas and surrounded by a hazy shell. In the background on the left, we see a brightly shining disk whose diameter is about 1/6 the planet’s size. Both objects are located in front of a black background with occasional bright dots.

Simulations provide a potential explanation for the mysterious gap in the size distribution of super-Earths. more

Twins, Triplets, Quadruplets and more: Observations show massive stars are indeed born as multiples

The important role of multiple star births has been confirmed for the first time by systematic observations. A detailed study with the ALMA radio observatory, in which four binary protostars, a triple, a quadruple and a quintuple system were found in a massive star cluster, confirms our understanding of the formation of massive stars. more
