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.
This Hubble Space Telescope image shows globular cluster NGC 1783 in the Southern Hemisphere constellation of Dorado. NGC 1783 lies within the Large Magellanic Cloud, a satellite galaxy of our Milky Way, some 160,000 light-years from Earth. NGC 1783 is thought to be less than 1.5 billion years old — very young for a globular cluster.
Earth came early to the party in the evolving universe. According to a new theoretical study, when our solar system was born 4.6 billion years ago only eight percent of the potentially habitable planets that will ever form in the universe existed. And, the party won’t be over when the Sun burns out in another 6 billion years. The bulk of those planets — 92 percent — have yet to be born.
