After being in orbit for almost 28 years, the Hubble space telescope might be coming to its end, but does it really have to be? Hubble is expecting a companion soon known as the James Webb space telescope. Hubble’s mission is expected to last into the 2020s, and the young new James Webb is expected for launch in 2019. Which means, for that one year, the two observatories will be working hand-in-hand in collaborative data. But when Hubble comes close to its end, what’s next?

Hubble has been in space for almost three decades. The equipment has been highly exposed to solar radiation in Lower Earth Orbit. The fine-guidance sensors, which are some of the original electronics from the very start of the mission, are beginning to degrade due to those high radiation levels. Hubble’s had 5 service missions, and its camera housing has been hit many times by space debris, it has impact craters.

Here enters James Webb, which isn’t replacing Hubble, but instead, complementing it. These observatories are very different from one another. Hubble’s images and data are found mainly in the visible and ultraviolet wavelengths. Its lead to discoveries like supermassive black holes being the center of most, if not all galaxies, and even confirmed the expansion of the universe.

James Webb, however, will mainly focus on infrared wavelengths, and because the mirrors have a six and a quarter (6.25) times more collecting area than Hubble it will be able to see way further into the universe than Hubble ever could.

The Large Space Telescope was renamed the Hubble (HST) out of appreciation for Edwin Hubble, an American cosmologist who, in addition to other things, established that the universe reached out past the outskirts of Milky Way. The world's first space telescope was then propelled on April 24, 1990.

Hubble's hoisted point of view and propelled optics enable it to peer more remote away than past ground-based optics can see. Since light sets aside an opportunity to movement long separations, the scope of the HST influences it to work like a time machine; the light it sees from remote questions just uncovers how that protest showed up when the light left it, not how it shows up today. In this manner when we take a gander at the Andromeda world, 2.5 million light-years from Earth, we consider it to be it was 2.5 million years back.

Hubble's pictures and information are discovered basically in the unmistakable and bright wavelengths. Its prompt revelations like supermassive dark openings being the focal point of most, if not all cosmic systems, and even affirmed the extension of the universe.

James Webb, nonetheless, will chiefly center around infrared wavelengths, and in light of the fact that the mirrors have a six and a quarter (6.25) times more gathering region than Hubble, it will have the capacity to see route assist into the universe than Hubble ever could.
