NASA has planned to build a Starshade to look for Alien Planets. Starshade exoplanet-hunting missions may be technologically daunting.
Do not miss to watch the longest blood moon or longest total lunar eclipse Now!
Blood moon happens on the same day the planet Mars reaches its opposition, when it will shine at its best in the night sky. From 2003 Mars has not been so close to Earth, and this month this unique phenomenon is happening. After opposition, when Mars will be brightest, it reaches that closest point on July 31.
“What controls the duration of the lunar eclipse is the position of the moon as it passes through the Earth’s shadow,” Petro told Space.com. The darkest part of Earth’s shadow is called the umbra. You can picture the umbra as a cone extending from Earth in the opposite direction to the sun, Petro explained. “The moon can either graze through the cone, or go right through the middle. That [the middle] gets a longer-duration eclipse,” he said. “This time, the moon is passing closer to the center of that cone, and it’s therefore a little bit longer than the eclipse we had back in January.”
