NASA Shares Photo Of Rare Event Involving Sun And Venus, Internet Amazed

According to NASA, a transit is when one object crosses in front of another in space. Transits help scientists find exoplanets, it added.

American space agency NASA has shared a post on its Instagram handle, describing a rare celestial event that took place about a decade ago. The event - transit of Venus across the face of Sun - was captured by the agency's Solar Dynamics Observatory (SDO).

"She was one of the rare ones, so effortlessly herself, and the world loved her for it," NASA said in the post, which carries the photo of the Sun and a dot-like Venus. It then described why solar transits are important events for astronomers.
