The Kepler mission’s announcement of 1,284 worlds previews the overwhelming number of planetary discoveries to come
Thirteen times a century, on average, Mercury passes directly between Earth and the sun, creating what astronomers call a transit. It just happened again; this video, created with images from the orbiting Solar Dynamics Observatory shows the tiny planet’s silhouette as it makes its seven-hour journey across the solar disk.
NASA’s MESSENGER spacecraft orbited Mercury for four years before its planned plunge and crash into the planet’s surface on April 30, 2015. On May 6, 2016, NASA, the USGS and their university partners showed what they had accomplished during the mission. They presented the first topographic map ever produced of Mercury, along with a color-enhanced view of its northern polar region. On May 9, 2016, Mercury's transit across the solar disk was visible from Earth—an astronomically rare event.
To do so, they looked to a second black hole orbiting the first
