• Astronomers noticed a glistening spot on Titan, one of Saturn's moons, that could indicate rainfall in the lunar satellite's northern hemisphere.
• The image was taken from the Cassini mission spacecraft, which entered Saturn's orbit in 2004.
• Rainfall has been observed from the moon's southern hemisphere, but this is the first time that rainfall was detected near its north pole.
• The rainfall may indicate that Titan has changing seasons similar to Earth's.
