On the Parabolic Curve of Primary Mirrors
... Abstract: In order for a parabolic mirror to work, light has to reflect off of every point on it and be directed in a straight line to the focus. With this in mind, we know a light ray traveling parallel to the y-axis and reflecting off of the point (x, f) has to be directed to the focus in a straig ...

XMM-Newton
The XMM-Newton, also known as the X-ray Multi-Mirror Mission and the High Throughput X-ray Spectroscopy Mission, is an orbiting X-ray observatory launched by ESA in December 1999 on an Ariane 5 rocket. It is named in honor of Sir Isaac Newton. The telescope was placed in a very eccentric 48 hour elliptical orbit at 40°; at its apogee it is nearly 114,000 kilometres (71,000 mi) from Earth, while the perigee is only 7,000 kilometres (4,300 mi).
