ELECTRIC BLUE This new “Blue Marble” image of Earth was produced by the VIIRS instrument aboard NASA’s most recently launched Earth-observing satellite, Suomi NPP. The composite image was assembled from image data captured from a number of swaths of Earth’s surface on Jan. 4 and is the best-known high-resolution images of our planet.

“There is an asteroid, discovered in December 2004, called Apophis. Named for the Egyptian god of death and darkness. It was named only after its trajectory was identified to intersect that of Earth… Turns out, in the year 2029, in the month of April… Apophis will come so close to Earth that it will dip below our orbiting communications satellites. And it is the size of the Rose Bowl. It will be the largest, closest thing we have ever observed to come by Earth. The orbit we now have for it is uncertain enough—because these things are hard to measure and hard to get an exact distance for—that we cannot tell you exactly where that trajectory will be. We know it won’t hit Earth, but we know it will be closer than the orbiting satellites. There is a range, a 600-mile zone, called the keyhole. If the asteroid goes through the middle of the keyhole, it will hit the Earth 7 years later. It will hit the Earth 500-kilometres west of Santa Monica. Now, that’s if it goes through the centre [of the keyhole]; if it goes through the centre, it hits the Pacific Ocean, plunges down into the Pacific to a depth of 3 miles, at which point it explodes, cavitating the Pacific in a hole that’s 3 miles wide, three 3 deep. That will send a tsunami wave outward from that location that’s 50 feet high. 5 storeys.”
