This morning in the blue dawn skies of South America, the quarter Moon eclipsed the planet Jupiter. In Buenos Aires, amateur astronomer Mariano Ribas photographed the pair in broad daylight just 25 minutes before the occultation.

If you look closely at Jupiter in Mariano's picture, you can even faintly see the stripes of the giant planet!

"It was an incredible sight," says Ribas. "Today, after the sunrise, the Moon eclipsed Jupiter as seen from Argentina. It was the first time for us to see a lunar eclipse of the giant planet since 1998!"
