Researchers identify two of the Milky Way's earliest building blocks

Astronomers have identified what could be two of the Milky Way’s earliest building blocks: Named “Shakti” and “Shiva”, these appear to be the remnants of two galaxies that merged between 12 and 13 billion years ago with an early version of the Milky Way, contributing to our home galaxy’s initial growth. 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
