The transit of Venus across the solar disk won't make it okay to stare into the sun. Here's how to watch this rare astronomical event safely.
The transit of Venus will help astronomers on the hunt for planets outside of our solar system.
The next transit of Venus occurs June 5. Astronomers once used the transit of Venus across the sun to come up with the 'astronomical unit' – the distance from Earth to our sun.
The planet Venus is due to pass in front of the sun on June 5th and 6th. It won't do so again until 2117.
Author Mark Anderson of 'The Day the World Discovered the Sun' explains how the transit of Venus allowed 18th-century astronomers to create an early GPS system.
Data from the orbiter DAWN confirm theories about the history of Vesta, which dates to the early days of planet formation. The protoplanet is also home to the solar system's second largest mountain.
Effulgent Venus will show just beside the moon today. Also, some cues on how to observe this rare and beautiful event.
New information collected by NASA's Messenger shows that Mercury was more geologically active than scientists previously thought.
New results from NASA's MESSENGER spacecraft show Mercury to have features unlike anything scientists have seen elsewhere in the solar system. Here's one: a huge core for a planet this size.
Beginning tonight, the two brightest planets in the sky will be so close together that you'll be able to block both of them out with a few fingers held at arm's length.
