Galileo was the first person to observe the rings of Saturn. He spent hour after hour on painstaking drawings of the Moon through its phases, observed Venus and Mars, and even made sketches of ...

In 1610, Galileo Galilei was the first to observe the rings, though his telescope was too crude to identify them as actual rings. He described them as "Saturn's ears" since they looked like two ...

In 1610, Galileo pointed his 20-power “optical tube” (his telescope) at Saturn and discovered “ears.” These odd appendages intermittently disappeared and reappeared over the course of a year.

When Galileo Galilei aimed his telescope at Saturn in 1610, he saw what looked like ears protruding from the planet’s disk. Two years later, the “ears” (which Galileo called stars) had vanished.

When he discovered the planet in 1610, looking through his primitive telescope, Galileo perceived Saturn's rings as two large moons, which he described as "handles," flanking the planet.

ON a memorable evening in the year 1610 Galileo sat in the tower of his observatory in Florence, and gazed through his newly-invented “perspective glass” at Saturn, which was then regarded as ...

Jupiter and Saturn will merge in the night sky Monday, appearing closer to one another than they have since Galileo's time in the 17th century.

They were spotted by Galileo Galilei more than 400 years ago, in 1610. Saturn’s first known moon, Titan, was discovered by Dutch astronomer Christiaan Huygens 45 years later.

Galileo was the first robotic probe to collide with a gas giant; Cassini will be the second. Cassini’s final marching orders outlined a grand finale of 22 orbits of Saturn.

Jupiter and Saturn will merge in the night sky to create a single "Christmas star" Monday, appearing closer to one another than they have since Galileo’s time in the 17th century ...
