See planets Jupiter, Venus, Mars and Saturn in April 2022 sky | Space

Growing up in the Bronx during the 1960s and '70s, one of my mentors in astronomy was Dr. Kenneth L. Franklin, Chairman and chief scientist at New York's Hayden Planetarium, who wrote about celestial events for the World Almanac and The New York Times. 

If you need some gear to see April's predawn planets, check out guides for the best telescopes and best binoculars to find the right instrument for you for the next skywatching event.

In January 1992, a pair of astronomers reported a discovery that changed the course of scientific history: They found planets outside our solar system.

The detection of the first confirmed exoplanets — the term for worlds that orbit other stars — validated dreamers who for centuries believed that "innumerable celestial bodies, stars, globes, suns and earths may be sensibly perceived therein by us," in the words of the Renaissance polymath ...
