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.
New images captured by the NASA/ESA Hubble Space Telescope (HST) confirm the presence of a dark vortex roughly 3,000 miles (4,800 kilometres) across in the atmosphere of Neptune. Though similar features were seen during the Voyager 2 flyby of Neptune in 1989 and by the HST in 1994, this vortex is the first one observed on Neptune in the 21st century.
Astronomers are using the NASA/ESA Hubble Space Telescope to study aurorae — stunning light shows in a planet’s atmosphere — on the poles of the largest planet in the solar system, Jupiter. This observation program is supported by measurements made by NASA’s Juno spacecraft, shortly to arrive at the gas giant.
