THE MILKY WAY’S GALACTIC BULGE
One of the most important and massive parts of the Milky Way galaxy is its galactic bulge, a huge central cloud of about 10 000 million stars spanning thousands of light-years.
Unfortunately, from our vantage point from within the galactic disc, the view of this central region — at about 27 000 light-years’ distance — is heavily obscured by dense clouds of gas and dust. Astronomers can only obtain a good view of the bulge by observing longer wavelength light, such as infrared radiation, which can penetrate the dust clouds.

IN THE BULGE:
A DWARF GALAXY SWALLOWED BY A YOUNG MILKY WAY
Peering through the thick dust clouds of our galaxy’s central parts with an amazing amount of detail, a team of astronomers has revealed an unusual mix of stars in the stellar grouping known as Terzan 5.
Never observed anywhere in the bulge before, this peculiar cocktail of stars suggests that Terzan 5 may be one of the bulge’s primordial building blocks, most likely the relic of a dwarf galaxy that merged with the Milky Way during its very early days. This near-infrared image was obtained with the Multi-conjugate Adaptive Optics Demonstrator (MAD) instrument on ESO’s Very Large Telescope. Credit: ESO/F. Ferraro (The star cluster Terzan 5)
