Hubble telescope spots signs of water on five planets~ If you dream of colonizing distant worlds, here’s welcome news: NASA’s Hubble Space Telescope has spotted signs of water on five faraway planets, according to two studies.
Mercury is the closest planet to the Sun and due to its proximity it is not easily seen except during twilight. For every two orbits of the Sun Mercury completes three rotations about its axis and up until 1965 it was thought that the same side of Mercury constantly faced the Sun. Thirteen times a century Mercury can be observed from Earth passing across the face of the Sun in an event called a transit, the next will occur on the 9th May 2016. This dataset was created using data from the…
Jupiter's Great Red Spot. The Great Red Spot is a great anti-cyclonic (high pressure) storm akin to a hurricane on Earth, but it is enormous (three Earths would fit within its boundaries) and it has persisted for at least the 400 years that humans have observed it through telescopes. Since it is anti-cyclonic in Jupiter's Southern hemisphere, the rotation is counterclockwise, with a period of about 6 days. (A hurricane in Earth's Southern hemisphere rotates clockwise.)
Eclipse of Venus -- NASA’s Picture of the Day on Aug.20, 2013. Usually it is the Earth’s Moon that eclipses the Sun. Last June, most unusually, the planet Venus took a turn. Pictured above during the occultation, the Sun was imaged in three colors of ultraviolet light by the Earth-orbiting Solar Dynamics Observatory, with the dark region toward the right corresponding to a coronal hole. The next Venusian solar eclipse will occur in 2117.
