Hubble to Observe Venus Transit

Astronomers are planning to use NASA’s Hubble Space Telescope to observe next month’s historic transit of Venus across the sun’s face. But there’s a twist. Astronomers can’t point Hubble anywhere near the sun, because our star’s bright light could damage the telescope’s super-sensitive instruments. So Hubble will watch the June 5-6 Venus transit by using the moon as a mirror. The goal is to see if Hubble can determine the makeup of Venus’ atmosphere by studying sunlight that has poured through it.
