Monthly Stargazing Calendar for April 2012
On April 15 the planet Saturn will be at Opposition. The ringed giant will be at its closest approach to the Earth and its face will be fully illuminated by the Sun. It will be the best time to view and photograph Saturn and its moons.
Astronomy Picture of the Week – Rings of Uranus
This series of images of the rings of Uranus were taken by NASA's Hubble Space Telescope. They were taken at different times when the rings were facing the Earth at slightly different angles. In the third image, the edge-on rings appear as two spikes above and below the planet.
Astronomy Picture of the Week – Planet Uranus with Moons
This is a photo montage of Uranus and five of it’s largest moons. The photos were taken separately by the Voyager 2 spacecraft. The moons, from largest to smallest as they appear here, are Ariel, Miranda, Titania, Oberon and Umbriel. When Voyager 2 visited the planet, it discovered 10 new smaller moons and took close-up pictures of its ring system. Image Credit: NASA/JPL
Astronomy Picture of the Week – The Rings of Saturn
This picture of Saturn’s rings in its natural colors has been taken by the Cassini probe from an angle impossible to get from Earth. We can see a huge gap in Saturn’s rings. This is caused by the planet obscuring the Sun’s light. Since the rings do not emit light on their own, a lack of sunlight would mean no reflected light, and thus they would remain dark. The rings are also projecting a shade on the planet near the equator for similar reasons, except here the roles are reversed. Saturn’s Rings by Cassini. Image credits: NASA/ESA
