A massive collision in the Milky Way's past

Our Milky Way galaxy has probably collided or otherwise interacted with other galaxies during its lifetime; such interactions are common cosmic occurrences. Astronomers can deduce the history of mass accretion onto the Milky ...

Star formation in galactic centers

Stars form from the gas and dust in molecular clouds via a series of complex processes that are currently only partly understood, and the evolution of these clouds drives the evolution of the stellar populations in the universe. ...

Ultra-sharp images make old stars look absolutely marvelous

Using high-resolution adaptive optics imaging from the Gemini Observatory, astronomers have uncovered one of the oldest star clusters in the Milky Way Galaxy. The remarkably sharp image looks back into the early history of ...

Hiding black hole found

Astronomers have detected a stealthy black hole from its effects on an interstellar gas cloud. This intermediate-mass black hole is one of over 100 million quiet black holes expected to be lurking in the galaxy. These results ...

In colliding galaxies, a pipsqueak shines bright

In the nearby Whirlpool galaxy and its companion galaxy, M51b, two supermassive black holes heat up and devour surrounding material. These two monsters should be the most luminous X-ray sources in sight, but a new study using ...

Uncovering the birthplaces of stars in the Milky Way

An international team of scientists led by Ivan Minchev of the Leibniz Institute for Astrophysics Potsdam (AIP) has found a way to recover the birth places of stars in our Galaxy. This is one of the major goals in the field ...
