3. New moons of Pluto
The currently known four moons of Pluto out of five on the orbit are discovered by the Hubble Telescope.
It helps NASA scientist to study dwarf planet Pluto in their New Horizons mission. Amy Simon from NASA Goddard Space Flight Center in Maryland says in a press conference that in the New Horizons mission they planned to fly thru Pluto in July with more objects to discern in this momentous flyby. In this project Hubble telescope is helping researchers to make best choice about new Horizons to check out after it flies past Pluto.
Amy Simon further added that now they have two target entrants who have been working with Hubble for 20 years. They are making an allowance for extending this mission because they believe that there is a place for new Horizons to target and it gets possible because of Hubble.
4. Exoplanet science
There is a large planet Fomalhaut b that is three times bigger to the size of Jupiter. Hubble telescope took the first image of this planet in visible light. With this telescope researchers can also collect data related to the atmospheres of alien planets and other valuable information.
Astronomer Jacob Bean says that if scientist observes planets during they orbit their stars, they can observe the changing face of the planet with the help of Hubble telescope. They can record temperature of the planet all the way around and also just at one side of the planet.
5. Find out the age of universe
Last but not the least this telescope foremost task was to measure the age and size of the universe. It help researchers to find out the age of universe as now they find out that the universe is about 13.7 billion years old using Hubble’s data. Hubble scientist says that the age of universe is not just for snooping and curiosity but by using a time scale for the development of stars and galaxies eventually refine everything. It helps in the making of more precise models regarding how the universe is formed and the whole shebang in it.
There is a special kind of star on the set cycle that pulses. Researchers measure the brightness of Cepheid variable star by using Hubble telescope. They made the comparison of the already known inherent brightness of the stars with this data to measure great distances in the universe.
