Data from Webb and Hubble combine to take viewers on a video tour from the present all the way back to 390 million years after the Big Bang and a never-before-seen early galaxy.

Most distant known galaxy surprises astronomers with heavy elements, gamma ray burst

22 December 2020 Astronomy Now

Astronomers confirm a galaxy 13.4 billion light years away is the most distant object yet found, raising new questions about how soon galaxies appeared in the wake of the Big Bang.

Newly discovered fast-growing galaxies could solve cosmic riddle

29 May 2017 Astronomy Now

Astronomers have discovered a new kind of galaxy in the early universe, less than a billion years after the Big Bang. These galaxies are forming stars more than a hundred times faster than our own Milky Way. The discovery could explain an earlier finding: a population of surprisingly massive galaxies at a time 1.5 billion years after the Big Bang, which would require such hyper-productive precursors to grow their hundreds of billions of stars.

Spiral-like patterns of star formation discovered in old galaxies

22 November 2016 Astronomy Now

Elliptical and Lenticular galaxies (historically referred to as early-type galaxies) are thought to be no longer giving birth to new stars. Now, a team led by astronomers from the Instituto de Astrofísica e Ciências do Espaço (IA) in Portugal has discovered optical spiral features in the outskirts of three nearby early-type galaxies, which points to a still ongoing inside-out growth.
