Ultra-faint dwarf galaxies—tiny satellite galaxies orbiting the Milky Way—have long been seen as cosmic fossils. Now, a new ...

By tracking individual stars and exploding supernovas, astronomers discovered the strength of early ultraviolet glow ...

Ultra-faint dwarf galaxies orbiting the Milky Way are cosmic fossils. New simulations reveal how these tiny systems reflect ...

Our universe is full of mysteries, but few are as perplexing as the dark, tiny galaxies that hover around larger ones like ...

Astronomers have used high-resolution simulations to study ultra-faint dwarf galaxies orbiting the Milky Way, finding that their present-day properties are highly sensitive to conditions in the early ...

The first time I heard about galaxies without dark matter, I was sitting in my very first graduate class at the University of São Paulo. It was 2018, and the discovery had just been announced. A team ...

A new study has probed the possibility of some of the smallest galaxies in the universe, particularly dwarf spheroidal galaxies orbiting the Milky Way, hosting black holes. This can help advancing ...

Scientists explore if dwarf spheroidal galaxies, the universe's smallest, contain black holes, potentially reshaping our ...

Astronomers have used high-resolution simulations of ultra-faint dwarf galaxies to probe the 'climate' of the early universe. Led by Dr. Azadeh Fattahi, the study modeled the smallest galaxies to ...

It looks like this detailed image of a far-off galaxy was captured an advanced space telescope, or a huge ground-based scope.

A team of astrophysicists from Nanjing University and University of Bonn have demonstrated that, rather than being random, ...
