An international team of astronomers reports the detection of a black hole in a globular cluster known as NGC 1850. The newly found black hole is about 11 times more massive than the sun and turns out to be a part of a binary ...
The mass distribution of stars is called the initial mass function, or IMF for short, and it characterizes the properties not only of our Milky Way, but of all the other galaxies we observe as well. But is the IMF constant? ...

(Phys.org) -- Over the past several years there has been debate in the astrophysics community regarding the distribution of stars in galaxies, specifically their mass range. Astronomers use an initial mass function (IMF) ...
There may be a large number of undetected bright, substellar objects similar to giant exoplanets in our own solar neighborhood, according to new work from a team led by Carnegie's Jonathan Gagné and including researchers ...

Our Milky Way is thought to be home to as many as 400 billion stars, one of which is, of course, our own sun. But how and when did these stars form, and where did they come from?
