The Hubble Space Telescope’s Advanced Camera for Surveys captured this stunning image of the globular cluster NGC 1783, a spectacular collection of suns in the Large Magellanic Cloud some 160,000 light years from Earth with a total mass of about 170,000 times that of the Sun. Based on the colour and brightness of its stars, NGC 1783 is thought to be less than 1.5 billion years old, a relative youngster when it comes to globular clusters. It is thought to have undergone at least two episodes of star formation 50 million to 100 million years apart.
Haumea, a dwarf planet on the edge of our solar system, doesn’t have the same kind of moons as its well-known cousin Pluto according to a new study. This is despite original evidence that suggested they both formed in similar giant impacts and adds to the mystery shrouding how these icy bodies formed.
It may be famous for hosting the Small Magellanic Cloud (SMC) and 47 Tucanae, the second brightest globular cluster in the night sky, but the southern constellation of Tucana (The Toucan) also possesses a variety of unsung cosmic beauties. One such beauty is NGC 299, an open star cluster located within the SMC just under 200,000 light-years away.
The Atacama Large Millimetre/submillimetre Array has produced a spectacularly detailed image of a distant galaxy known as SDP.81 that is being gravitationally lensed. The image shows a magnified view of the galaxy’s star-forming regions, the likes of which have never been seen before at this level of detail in a galaxy so remote.
