A “gem” of a young star cluster shines in Carina

16 March 2021 Astronomy Now

A beautiful star cluster in Carina, known as the Gem, was first observed in 1757. The young, 10-million-year-old cluster is seen here in all its glory courtesy of ESO’s 2.2-metre MPG telescope at La Silla Observatory in Chile.

A massive middle-age star cluster in the Small Magellanic Cloud

Massive middle age star clusters like NGC 339 resemble more common globulars, but they are much younger and it’s not yet known how they might be related. This remarkably detailed view comes from the Hubble Space Telescope.

Galaxies peek through star clouds in massive cluster

A middle-age star cluster in the Small Magellanic Cloud is populated by countless stars, but galaxies in the far distance peak through, giving viewers at least a sense of the overwhelming scale of the cosmos.

Astronomers collect spectra in search for Sun’s lost siblings

Australian astronomers are in the process of collecting the spectra of a million stars across the Milky Way in a project to study galactic evolution. In the process, they hope to track down at least some of the sun’s lost siblings.

The secret life of the Orion Nebula

16 May 2016 Astronomy Now

Space bears witness to a constant stream of star births. Whole star clusters are often formed at the same time — and within a comparatively short period. Researchers from the Max Planck Institute for Astronomy in Heidelberg have proposed a new mechanism that relies on the interplay between magnetic fields and gravitation to explain this quick formation, investigating a filament of gas and dust which also includes the well-known Orion Nebula.
