The solar system is made of the eight planets that orbit our sun it is also made of asteroids, moons, comets and lots, lots more. The sun has such powerful gravity it tries to pull the planets towards it. While the planets try to fly away in the end they are kind of in the middle floating around the sun. They are 140 moons that orbit the eight planets in the solar system. The moons don’t...

Vixen has introduced a remarkable looking 7-element ocular that yields an expansive 83° apparent field. Yet the optical somersaults entailed in doing so are achieved without harm to the final image, yielding a stellar field with sharp edge-to-edge field definition with no vignetting – even on instruments of low focal ratio, says reviewer Steve Ringwood. Now that scientists have confirmed the...

The total lunar eclipse was going to occur from about 5:30 to 6:30 on Wednesday morning. My alarm was set for 6:00, like usual, and the forecast was for perfectly clear skies. I was awake fifteen minutes before my alarm but patiently waited until six o’clock, because the only upstairs windows that face west where the eclipsed Moon was setting are in my children’s bedrooms. I was not awake...

(DAS) solar astronomers will provide members of the public with safe views of the Sun in white, hydrogen alpha (deep-red) and calcium K (deep purple) spectral colors of the Sun. Hopefully the Sun and Earth's weather will cooperate and allow visitors to view sunspot groups, huge prominences -– many times the size of Earth -- and other changing features visible on the nearest star, which is now...
