A NASA-funded team of scientists has discovered long-lasting radio signals emanating from the Sun that are similar to those associated with auroras – northern and southern lights – on Earth. Detected about 25,000 miles (40,000 km) above a sunspot – a relatively cool, dark, and magnetically active region on the Sun – such radio bursts […]

The cosmos comes alive in an all-sky time-lapse movie made from 14 years of data acquired by NASA’s Fermi Gamma-ray Space Telescope. Our Sun, occasionally flaring into prominence, serenely traces a path through the sky against the backdrop of high-energy sources within our galaxy and beyond. “The bright, steady gamma-ray glow of the Milky Way […]
