When a massive star in the Milky Way's Ophiuchus constellation blew up, it spread rays of light so bright, that they exceeded the brilliance of Mars when they reached Earth, in 1604. Within a few days of the first sighting, the light source was even brighter than Jupiter.
This amazing image was collected using... |
