Huble 25 years plus and still working

I didn't even said anything about Hubble Space Telescope 25 years of being in space and making so many discoveries.Well here are some!
1)The telescope's observations of a special kind of supernova type 1a were crucial to the discovery that the universe was dominated by a mysterious factor known as dark energy, which appears to be behind the accelerating expansion of the universe. The discoverers won the Nobel Prize for physics in 2011. Well they count all the mass of the universe or they though they did when they obverse the most distance galaxies they expect them to begin their slow down and start moving inward but surprise they was moving ever faster!!!!
2)Hubble set records for its far-seeing views of the cosmos. Those views showed that galaxies started forming earlier in the universe's history than scientists expected, and that they look very different from the galaxies that are closer to us in time and space.
3)Studies of how the universe has changed over time, made possible by Hubble and other space observatories, helped physicists narrow down their estimates of the observable universe's age to 13.8 billion years.This was one of the reason they build the HST.
4)Hubble's detailed observations of gravitational interactions in distant galaxies led scientists to conclude that there are supermassive black holes at the centers of virtually all large galaxies — including our own.
5)Hubble provided amazing shots of Mars, Jupiter and Saturn, charted new moons and rings around Uranus, and spotted four previously unknown moons of Pluto. Its observations of Comet Shoemaker-Levy 9's crash into Jupiter was a wake-up call about cosmic impacts.Plus they used Hubble after the impacts to look deeper into JUpiter clouds.
6)The telescope and its team also helped get the ball rolling for the study of planetary systems beyond our own. Last year, scientists used Hubble's observations to produce the best weather map ever created for an extrasolar planet.
They hope if Hubble last long past its 2030 when Hubble orbit will make it hit deeper into Earth atmosphere when it does this soon it will force to burn up,but there are group that want to save when the new manned space ship and rocket are ready.They said NASA shouldn't just allow it to burn up.They are also talking about replacing it but with NASA budget the way its is this mightn't happen.It would need a very good repair mission almost everyting would need to be replace plus a higher orbit as well.Only time will tell how we treat such highlly working telescope that made so many discovery!
But the James Webb Space Telescope (JWST), would be in space let just hope they test out the mirror unlike the HST they launch it and its mirror was screwup with the JWST it orbit would be a million miles away.I just said they should test it out and not let history repeat. LOL While the Hubble view of the universe in the near ultraviolet, visible, and near infrared spectra.JWST mainly a primarily an infrared instrument, its coverage extends down to 600 nm wavelength light, or roughly orange in the visible spectrum. A typical human eye can see to about 750 nm wavelength light, so there is some overlap with the longest visible wavelength bands, including orange and red light. So the pics would look different...
