A brand new picture of a photo voltaic eclipse could have you seeing double. Views from the sun-watching Proba-2 satellite tv for pc present the moon passing in entrance of the solar in two footage snapped throughout a partial photo voltaic eclipse on Saturday (Aug. 11). The satellite tv for pc flew via the moon’s shadow twice throughout the eclipse.
Photo voltaic eclipses occur when the moon strikes between Earth and the solar, from the Earth’s perspective. A cheerful cosmic coincidence means the moon is nearly the identical obvious measurement within the sky as our solar, so typically the moon can block the solar fully. Like final 12 months, when a complete photo voltaic eclipse handed throughout the continental U.S.
This time round, the eclipse was a partial one, and a special area of the world acquired to witness it. The eclipse path included most of Asia, far northern Europe, Iceland, Greenland and a little bit of northern and japanese Canada. The occasion was the third and closing photo voltaic eclipse for 2018, and astrophotographers captured photographs all alongside the eclipse’s path.
Whereas the eclipse wowed observers on the bottom, Proba-2 acquired to witness the occasion from area. The European Area Company satellite tv for pc orbits Earth a little bit greater than 14 occasions per day, and its viewing angle modifications with every orbit. So the satellite tv for pc flew out and in of the moon’s shadow twice whereas the eclipse was taking place.
The pictures have been captured at four:40 a.m. EDT (0840 GMT) and 6:32 a.m. EDT (1032 GMT) utilizing the satellite tv for pc’s digital camera, which known as SWAP (Solar Watcher Utilizing Energetic Pixel System Detector and Picture Processing). The digital camera observes the corona — the tenuous and ultra-hot outer ambiance of the solar — in excessive ultraviolet wavelengths.
Coincidentally, NASA despatched a spacecraft to the solar that very same weekend. The Parker Photo voltaic Probe launched efficiently on Sunday (Aug. 12) from Cape Canaveral Air Drive Station in Florida. Parker is designed to fly nearer to the solar than ever earlier than, at a minimal distance of four million miles (about 6.5 million kilometers). That is 9 occasions nearer than planet Mercury’s orbit across the solar.
