Today, April 7th, the sun, Earth and Jupiter are almost perfectly aligned. Or, as an astronomer would say, “Jupiter is at opposition.”
From our point of view on Earth, Jupiter and the sun are on opposite sides of the sky. At opposition, the giant planet rises at sunset and stays up all night long.
This is also the time when Jupiter is closest to Earth. Even small telescopes reveal Jupiter’s moons and stormy cloud belts.
