There's a space station in a decaying orbit. It's going to fall back to Earth. And we don't know where or when it will hit.
No, this isn't the plot of a terrible action movie. The Chinese space station Tiangong-1 is headed for an uncontrolled reentry into Earth's atmosphere. The European Space Agency (ESA) has been monitoring the situation; today, it delivered an update narrowing down the crash window. The space station will fall somewhere between 43 degrees North and South, but because of the angle of the Tiangong-1, it's more likely to fall near the maximum or minimum than on the equator. The reentry time frame is between March 29th and April 9th, but the ESA notes that this is highly variable.
