Scientists 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. Researchers 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 transitby 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. Astronomers already know a great deal about Venus’ air, so next month’s observations are a test run to see if the technique could be used to determine the atmospheric composition of faraway alien planets, researchers said.
