Tired of your view of the sky? Try the view from the moon: The picture sharpens, and the possibility of hindering clouds disappears.

This is the proposition underlying "World of Tomorrow", a dazzler shown at Air and Space's Spacearium 11 times a day. For 50 cents (25 cents for children, students and senior citizens) you can ponder life on Mars, examine some likely sources for alien beings, and witness a thunder storm on Jupiter that would curl Vincent Price's toes.

Air and Space also runs a Saturday-morning lecture, bringing viewers up-to-date on the month's phenomena. The Oct. 6 lecture includes a discussion of how far you can see with the naked eye. The answer stretches into the trillions.

Another way to keep current on heavenly occurrences is to call the Smithsonian's Dial-a-Phenomena (737-8855). A tape recording lists sun spots, planet positions and other happenings.

Programs at Arlington's planetarium (1426 N. Quincy St.) will include one on the age of the universe, an adaptation of science-fiction writer-astronomer Fred Hoyle's book, "Black Cloud," and a show about Albert Einstein's contribution to physics, "But really," says Smith, "it's about how touchingly human he was."

Call the planetarium (558-2868) for a schedule.
