Over about 4 hours on June 18th 2015, NASA’s Solar Dynamics Observatory captured a developing flare and coronal mass ejection. This video depicts the event at multiple wavelengths. The vibrant 304 Angstrom wavelength seen at the beginning reveals material in the "lower parts of the Sun atmosphere, colorized in red.
The supermassive black hole is 40 million times as massive as the sun and powers a quasar that existed 700 million years after the Big Bang.
The asteroid zoomed by Earth at a perfectly safe distance of around 1.8 million miles (2.9 kilometers).
Images show surprise changes to the spacecraft as it interacted with the atmosphere.
