Direct Measurements of Pulsar Acceleration Reveal Nature of Milky Way's Dark Matter

It is well known that the expansion of the universe is accelerating due to a mysterious dark energy. Within galaxies, stars also experience an acceleration, though this is due to some combination of dark matter and the stellar density.

Study Reveals the Double Origin of Cosmic Dust in the Distant Universe

Two billion years after the Big Bang, the Universe was still very young. However, thousands of huge galaxies, rich in stars and dust, were already formed. An international study, led by SISSA - Scuola Internazionale Superiore di Studi Avanzati, now explains how this was possible.

ALMA Captures a Far-Away Galaxy Ejecting Its Star-Forming Gas

Galaxies begin to "die" when they stop forming stars, but until now astronomers had never clearly glimpsed the start of this process in a far-away galaxy. Using the Atacama Large Millimeter/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner, astronomers have seen a galaxy ejecting nearly half of its star-forming gas.
