Uranus releases about 15% more energy than it receives from the Sun, according to two new papers published in the journal Monthly Notices of the Royal Astronomical Society and the journal Geophysical Research Letters. Composite image of Uranus. Image credit: Marcos van Dam / W. M. Keck Observatory. Uranus is unlike any other planet in our Solar System. It spins on its side, which means each pole directly faces the Sun for a continuous 42-year ‘summer.’ This...

This Hubble image shows NGC 1786, a globular cluster located about 163,000 light-years away in the constellation of Dorado. The color image was made from separate exposures taken in the ultraviolet, visible and near-infrared regions of the spectrum with Hubble’s Wide Field Camera 3 (WFC3). Three filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter.
