Hubblecast 27: What Hubble Taught Us About The Planets.
For nineteen years, NASA/ESA’s Hubble Space Telescope has made some of the most dramatic discoveries in the history of astronomy but it has also helped scientists learn more about our own Solar System. From its vantage point 600 km above the Earth, Hubble has studied every planet in our Solar System except Mercury where light from the Sun would damage its instruments.

Hubble has captured the impact of a comet on Jupiter, immense storms on Neptune and even tiny dwarf planets at the edge of our Solar System. The veteran telescope keeps a watchful eye on our solar backyard.
Regarded by many as the most valuable astronomical tool, the Hubble space Telescope is approaching its 19th anniversary in space. Hubble sees into the far reaches of the Universe but its powerful instruments have also surveyed our planetary neighbours. In this episode, well see what Hubble has revealed to us in our own solar backyard.
Even those who, for some strange reason, arent astronomy enthusiasts are likely to recognise some of Hubbles most famous images, like the “Pillars of Creation”in the Eagle Nebula or the Hubble Deep, and Ultra Deep, Fields which have shown us some of the most distant galaxies ever observed. The Hubble Space Telescope has really fundamentally changed our understanding of the universe at large, but with its high resolution images of planets and moons in our own Solar System, it has also taught us a lot about our own cosmic neighbourhood.
Hubble cannot observe our Sun, or the closest planet, Mercury, because its instruments are light-sensitive and would be damaged. However, the telescope has examined every other planet in the solar system, including dwarf planets Pluto, Ceres and Eris. But, of course, Hubble does not just produce pretty pictures, it provides planetary scientists with vital information about our neighbours that may help us better understand our own home planet, Earth.

The universe has long captivated us with its immense scales of distance and time. How far does it stretch? Where does it end and what lies beyond its star fields and streams of galaxies extending as far as telescopes can see? These questions are beginning to yield to a series of extraordinary new lines of investigation and technologies that are letting us to peer into the most distant realms of the cosmosBut also at the behavior of matter and energy on the smallest of scales. The mind-blowing answer comes from a theory describing the birth of the universe in the first instant of time.
