NASA Mission Done By Hubble Space Telescope

Hubble Space Telescope
The Hubble space telescope is named in honor of astronomer Edwin Hubble.
Hubble's launch and development in April 1990 marked the most significant advance in astronomy since Galileo's telescope.

 Thanks to 5 servicing missions and more than 25 years of operations,our view of the universe and our place within it has never been the same. From the dawn of humankind to a mare 400 years ago, all that we know about our universe came through observations with the naked eye. Then Galileo turned his telescope toward the heaven in 1610. The world was in for an awakening.
 Saturn, we learned, had rings. Jupiter had moons.That nebulous patch across the center of the sky called the milky way was not a cloud but a collection of countless star. Within but a few years, our notion of the natural world would be forever changed. A scientific and societal revolution quickly ensued.

Hubble Eyes an Emitting Galaxy

When astronomer explore the contents and constituent part of Galaxy somewhere in the universe, they use various techniques and tools. one of these is to spread out the incoming light from that Galaxy into a spectrum and explore its properties. This is done in much the same way as a glass prism spreads white light into its constituent wavelengths to create a rainbow. By hunting for specific signs of emissions from various elements within a galaxies spectrum of light so called emissions lines or conversely, the signs of absorption from other elements so called absorption lines. Astronomers can start to deduce what might be happening within. 
Spectroscopy tell us about a galaxies type and compositions, the density and the temperature of any emitting gas,the star formation rate, or how massive the Galaxy Central black hole might be.

Herbal Studies Gamma-Ray Burst With Highest Energy Ever Seen

NASA's Hubble space telescope has given astronomers a peek at the location of the most energetic outburst has ever seen in the universe—a blast of gamma rays trillion times more powerful then visible light. That's because in a few seconds the gamma rays burst emitted more energy than the sun will provide over its entire 10 billion year life.

Hubble's observations suggest that this particular burst was sitting in a very dense environment, right in the middle of a bright Galaxy 5 billion light year away. This is really unusual, and suggest that this concentrated location might be why it produce this exceptionally power light.

Discoveries

Hubble has transformed our understanding of the universe, it's view from orbit blessing a flood of cosmic discoveries that have changed astronomy forever.

From its explorations of dark matter to its quest to determine the age of the universe, Hubble has helped has answer some of the most compelling astronomical questions of our time, and revealed enigmas that we never knew existed. Throughout history, humanities eyes on the universe has never seen with more clarity or focus.
