The Solar spots - are the dark formations on the Sun's disk. ... The greatest observed spot is 100 thousand kilomiters. The spots are the places of the magnetic fields' getting out to the solar atmosphere. ... That's why they look so dark . ... The Solar convection zone is the layer with the thickness of 150 - 200 thousand kilomiters, situated under the photosphere; the substance of this layer being in convectional movement transformes the energy from inside the Sun's to its surface. ...

... Ever since K.Tsiolkovsky laid theoretical foundations for a method to break the bonds of Earth's gravity and reach space, the dream of flying to other planets in our Solar System graduated from the realm of pure fantasy into a field of practical activities. ... Design work on manned mission to planet Mars which, among all the planets in our Solar System, has environments that are closest to those of Earth, started at RSC Energia almost as early as the work on first manned spaceflights. ...

... part 2 | ... Part 1 . The new concept of formation and development of the Solar system. ... Thus, the initial pulse of the rotation of a protosolar cloud of the solar system was determined as a result of the diversion of a part of the moment of the rotational pulse of the Galaxy. ... Besides this new approach to the pre-solar system as a system of the destroyed vortex structure, we can understand now a number of other peculiarities of the Solar system's structure. ...

. NEVER look directly at the sun without a proper solar filter! . We have lots of different equipment available for use. Here you see our 6" solar filters. Our club always recommends that you use a FULL APERTURE solar filter. In the picture you will notice a TYPE 2 filter for VISUAL use and a TYPE 3 filter for PHOTOGRAPHIC use. Here is an easy way to remember which type solar filter you need for VISUAL OBSERVING: You have 2 EYES so you need a TYPE 2 filter!! .

Launched on February 17, 1996, the Near Earth Asteroid Rendezvous (NEAR) mission is to be the first of NASA's Discovery missions, a series of small-scale spacecraft designed to proceed from development to flight in under three years for a cost of less than $150 million. ... The ultimate goal of the mission is to rendezvous with and achieve orbit around the near Earth asteroid 433 Eros in February, 1999, and study the asteroid for approximately one year. ...
