Estudar essas atmosferas pode aprofundar nossa compreensão do desenvolvimento de moléculas como a água e o metano, vitais para o surgimento da vida. Algumas anãs marrons podem até ser planetas desonestos ejetados de seus sistemas estelares! Desvendar os mistérios desses nômades cósmicos fornece informações sobre a formação de sistemas estelares e planetários.

One way around these problems is to project an image of the Sun from your telescope onto a card or screen. Now nobody has to look through the telescope (which means no refocusing and no bumping), and many people can view the solar image at the same time. But, as noted above, there’s a risk that someone might accidentally look into the bright beam of sunlight emerging from the eyepiece.


The solution to that problem, and an even safer way to use a telescope to observe the Sun, is rear-screen projection. 


"Build a Sun Funnel for Group Viewing of the Great American Solar Eclipse of August 21, 2017" is a step-by-step illustrated guide to constructing a simple, inexpensive rear-screen-projection device that enables multiple people to observe an optically projected image of the Sun simultaneously and safely. The document is intended for knowledgeable amateur and professional astronomers who know how to operate a telescope for solar observing.
