Introduction to the Dobsonian Telescopes

Due to magnification, the size of the field you see in the eyepiece is little (not much more than the size of the Moon would fit in the telescope), so you need to use an aiming device. Such a device, called a TELRAD, is mounted on the side of the te ...

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).
