Engineering Lightweight Dobsonian Telescopes

Since we are building a large Dob for deep space objects, you probably desire the brighter images from a large mirror, and wide field views from low magnification. After choosing the biggest mirror you and your budget can handle, the first part of t ...

Near-Earth Objects - The Koschny Family

But this is not what your results show — or at least, should not be. Why do the ratios IN(0)/I1(0) have the values you found ...

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).
