Anatomy of a cosmic snake reveals structure of distant galaxies
more »
We have a fair understanding of star formation, from the interstellar matter to the diffuse clouds whose gravitational contraction gives birth to stars. But observations of distant galaxies have questioned this picture, the size and mass of these distant stellar nurseries exceeding that of their local counterparts. Astrophysicists have tackled this inconsistency and found the first answers thanks to the observation of the cosmic snake.

Gravitational waves from merging supermassive black holes will be spotted within 10 years
more »
New research predicts that gravitational waves generated by the merger of two supermassive black holes -- the strongest gravitational waves in the universe -- will be detected within 10 years. The study is the first to use real data, rather than computer simulations, to predict when such an observation will be made.

What seemed at first like a rare instance of a huge, ancient galaxy revealed itself to be an even rarer pair of extremely massive galaxies, seen on the brink of merging when the Universe was only a billion years old.

NASA's James Webb Space Telescope Early Science Observations Revealed
First Publicly Available Science Observations for Webb Announced
The Space Telescope Science Institute is announcing some of the first science programs NASA's James Webb Space Telescope will conduct following its launch and commissioning. These specific observations are part of a program of Director’s Discretionary Early Release Science (DD-ERS), which will provide the scientific community with immediate access to Webb data. These data will help inform proposals for observations in the second year of Webb operations. The 13 ERS programs will address a broad variety of science areas, from black hole growth and the assembly of galaxies to star formation and the study of exoplanets.
