In search of the invisible galaxy

A mysterious and very distant object, in a universe as it was 'just' two billion years after the Big Bang, hides from even the most advanced instruments. Its features have finally been described by a team from SISSA in a ...

Astronomers observe light bending around an isolated white dwarf

Astronomers have directly measured the mass of a dead star using an effect known as gravitational microlensing, first predicted by Albert Einstein in his General Theory of Relativity, and first observed by two Cambridge astronomers ...

A new approach to solving the mystery of dark energy (Update)

What is behind dark energy—and what connects it to the cosmological constant introduced by Albert Einstein? Two physicists from the University of Luxembourg point the way to answering these open questions of physics.

Astronomers spot an orphaned protostar

Astronomers have performed an impressive suite of observations at multiple wavelengths of the same system, dubbed the HH 24 complex. This complex hosts stars in the process of being born and the impacts of their violent interactions ...

How did the Butterfly Nebula get its wings? It's complicated

Planetary nebulae form when red giant stars expel their outermost layers as they run out of helium fuel—becoming hot, dense white dwarf stars that are roughly the size of Earth. The material that was shed, enriched in carbon, ...
