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.
The fuzzy collection of stars seen in this NASA/ESA Hubble Space Telescope image forms an intriguing dwarf galaxy named LEDA 677373, located about 14 million light-years away from us in the constellation Centaurus. This particular dwarf galaxy contains a plentiful reservoir of gas from which it could form stars, but it stubbornly refuses to do so. Why?
A distant planet orbiting two red dwarf stars, found by its warping of spacetime, has been confirmed using observations from the NASA/ESA Hubble Space Telescope. The planet’s mass caused what is known as a microlensing event, where light is bent by an object’s gravitational field. This is the first circumbinary planet to be confirmed following detection of a microlensing event.
