Hubble resolves globular cluster in the Large Magellanic Cloud

20 June 2016 Astronomy Now

This NASA/ESA Hubble Space Telescope image shows the globular cluster NGC 1854, a gathering of white and blue stars in the southern constellation of Dorado. NGC 1854 is located about 135,000 light-years away, in the Large Magellanic Cloud (LMC), one of our closest cosmic neighbours and a satellite galaxy of the Milky Way.

Globular clusters make new stars by ‘adopting’ stray cosmic gases

27 January 2016 Astronomy Now

An international research team of astronomers has, for the first time, found young populations of stars within globular clusters that have apparently developed courtesy of star-forming gas flowing in from outside of the clusters themselves. This method stands in contrast to the conventional idea of the clusters’ initial stars shedding gas as they age in order to spark future rounds of star birth.

The Magellanic Clouds and an interstellar filament

Portrayed in this image from ESA’s Planck satellite are the Large and Small Magellanic Clouds, dwarf galaxies that are among the nearest companions of our Milky Way. The Large Magellanic Cloud, about 160,000 light-years away, is the large red and orange blob close to the centre of the image. The Small Magellanic Cloud lies some 200,000 light-years from us.

Dark energy survey finds eight more galactic neighbours

18 August 2015 Astronomy Now

Scientists on the Dark Energy Survey, using one of the world’s most powerful digital cameras, have discovered eight more faint celestial objects hovering near our Milky Way galaxy. Signs indicate that they, like the objects found by the same team earlier this year, are likely dwarf satellite galaxies — the smallest and closest known form of galaxies.
