A potentially disrupting satellite system around the LMC has been observed for the first time by astronomers
...more than a dozen new candidate dwarf galaxies and globular clusters in the last few years. And it appears ...that, “SMASH 1 would be one of only a few known disrupting globular clusters and the first such object to be discovered around the LMC.” For...

Astronomers find a group of stars dying too early
... significant step forward for Australia's observational capacity. With HERMES, astronomers in Australia have the chance to observe globular clusters without the need for using telescopes overseas, not only that, but HERMES is capable of analysing the...

First inactive stellar-mass black hole found in a globular cluster
...inactive black hole found in a globular cluster, that has such a very low mass. Globular star clusters are among the oldest known stellar... black hole! The first one found in a globular cluster by directly observing its gravitational pull,” said lead ...

Astronomers weigh the galaxy with Hubble and Gaia
... for something that has escaped all detection so far, they measured the velocities of globular clusters to work out the mass of the Milky Way. Globular clusters are isolated, densely packed, spherical collections of ancient stars, that orbit the...

Astronomers find ultra diffuse galaxy heavy in dark matter
... paper recently published in the journal Astrophysical Journal Letters. VCC 1287 resides within the Virgo Cluster, surrounded by a swarm of globular clusters (GCs) and it is the kinematics of seven associated GCs that Beasley and his team measured...

A see-through galaxy questions the need for dark matter
...and the invisible glue that holds galaxies and galaxy clusters together. Although it has never been directly observed,... fewer stars. By looking at the dynamical properties of ten globular clusters – essentially, a very large ball of stars – orbiting ...
