With India's successful Chandrayan-3 lunar mission. I thought it would be a good idea to provide readers with some historically great space achievements by humanity.
First question is. 'where exactly are we in the universe?'
The image provided here is that of of our galaxy called the 'Milky Way Galaxy' which contains billions of stars including our sun. Our sun is relatively so small that it cannot even be seen at this scale. Its location is marked in red.
To expand our understanding and learning of our universe, NASA (National Aeronautics and Space Administration) and ESA (European Space Agency) in 1990 launched a space based telescope called 'The Hubble Space Telescope'
Named as a tribute to Edwin Hubble, The Hubble Space Telescope is a robotic telescope located on the outer edge of the atmosphere, in circular orbit around the Earth at a height of 593 km, with an orbital period of 96 minutes at a speed 28,000 km/hr.
Cylindrically shaped Hubble weighs 11 tons. Its length is 13.2 m and its maximum diameter is 4.2 meters.
In Sept 2003, scientists pointed the Hubble at a small area seemingly about a 10th of the size of the full moon. After 4 months this is what they were able to observe.
We have been able to capture images only 13.8 billion years old. Our Universe is still expanding and limited by our capabilities we shall never be able to truly knows its vastness.
Intrinsically we humans always wander and wonder and thus Space is one of the ultimate frontiers. We salute all great men and women who have helped take us outside so that we may look within to understand our own selves better.
