Hubble telescope beams close-up of Jupiter, shows famous great red spot
Europe : The European Space Agency (ESA) in the Hubble Space Telscope has beamed back a close up image of Jupiter showing its famous Great Red Spot and several colourful bands, running parallel to the equator.
This new discovery will be added to many others in the past discovered and together they will allow astronomers to study changes in the atmosphere of the gas giant.
This month, Jupiter is at its closest to the Earth and the hemisphere facing our planet is fully illuminated by the Sun.The Hubble Space Telescope used this configuration to capture an image of what is by far the largest planet in the Solar System.
On April 3, Hubble took advantage of this alignment using its Wide Field Camera 3 (WFC3), and turned towards Jupiter to add to the collection of images of our massive neighbor.The final image shows a sharp view of Jupiter and reveals a wealth of features in its dense atmosphere.
On discovery it was found the surface of Jupiter is divided distinct, colourful bands, running parallel to the equator. These bands are created by differences in the opacity of the clouds which have different quantities of frozen ammonia; the lighter bands have higher concentration.
The most recognizable feature on Jupiter is the huge anticyclonic storm, called the Great Red Spot - this storm is large enough to engulf a whole Earth-sized planet at once.
However, as with the last images of Jupiter taken by Hubble and telescopes on the ground, this new image confirms that the huge storm which has raged on Jupiter's surface for at least 150 years continues to shrink.
Next to the Great Red Spot a much smaller storm can be seen at farther southern latitudes - dubbed "Red Spot Junior".
On April 7, Jupiter will come into opposition, the point at which the planet is located directly opposite the Sun in the sky. This means that the Sun, Earth and Jupiter line up, with Earth sitting in between the Sun and the gas giant.
Opposition also marks the planet's closest approach to Earth - about 670 million kilometres - so that Jupiter appears brighter in the night sky than at any other time in the year.
