Discovering the building blocks of nuclear star clusters
Today’s paper combines new observational data from Gaia with 20 years of multi-wavelength data of the compact dwarf galaxy NGC 5253, reveal a triplet system of star clusters in the centre.

Gravitational lensing allows us to look out to cosmological distances. This time we see super star clusters!
Super star clusters are the superstars in astronomy. Do we know how they come to be?
Globular clusters are some of the most massive and densest star clusters observed. What are the progenitors of old globular clusters that we see orbiting the Milky Way and other galaxies? What evolutionary and dynamical effects have these clusters experienced? What determines the physical properties of old globular clusters? Why are there two “distinct” classes of globular clusters and what properties determine these physical states? These are the questions the authors aim to answer.
