For 26 years now, the HST (Hubble Space Telescope) has been enthralling us with its spectacular images of nebulae, galaxies, and other space phenomena.

However, the telescope does more than just take pictures all day for us to enjoy. The HST was a combined NASA(National Aeronautics and Space Administration) and ESA (European Space Agency) project, which went up with tons more scientific instruments than just a powerful camera.
Since being put in orbit, over 4000 astronomers have used it to publish ~13000 scientific papers on various topics. The HST is truly a marvel of civilization. When Hubble went up, it had a flawed mirror, which was sending back blurry images. After a 1993 servicing mission, the flaws were rectified, and from then, it’s been taking pictures of all the amazing things we know it for. It’s been used to look at other planets, their moons, further galaxies, and nebulae.

It’s been used to find water on planets, moons, and other asteroids. It’s been used to map Pluto, the furthest planet from us (now a dwarf planet). NASA’s New Horizons mission will rival the HST, but it will take 9 years to get close enough to Pluto to give any challenge to the HST.
It’s been used to calculate the lifespan of the universe, Hubble helped astronomers nail down the age of the universe with an accuracy of about 5 percent. Our Galaxy, the Milky Way is set to collide with the Andromeda Galaxy, speeding towards us at the speed of a bullet. We know this all thanks to Hubble.
The Bubble Nebula, also known as NGC 7635, is an emission nebula located 8 000 light-years away. This stunning new image was observed by the NASA/ESA Hubble Space Telescope to celebrate its 26th year in space.
“When massive stars reach the end of their lives, they explode in a fiery death known as a supernova. These violent blowouts may leave behind black holes or supercompact neutron stars even as they blow the heavy elements that form in the heart of the star through their galaxy. Hubble has helped scientists to better understand the supernova process.” – Space.com
