We are all very much aware about the Hubble Deep Field and the Hubble Ultra Deep Field. The Hubble Ultra Deep Field is the successor of Hubble Deep Field and so do Hubble space telescope has theirs. And NASA’s Roman Space Telescope is one of the Hubble’s successors.
These two deep field have shown that even an empty looking mark in the sky is full of galaxies with all sizes, shapes and ages. A generation of people have also experienced about how amazing and expensive the universe is.The Roman Space Telescope is also known by the name of Nancy Grace Roman Space Telescope with most famous images of its own and also capable of taking 100x larger area of the sky at once. Your mind will blow away after seeing this amazing images.
This telescope is expected to be launch in 2025 on a 5-year mission to research about cosmology and exoplanets as the telescope has its significant observing power.
If we talk about its architecture the mirror is of the same size as the Hubble’s i.e. 2.4 m (about 7ft 10in) in diameter. The Roman telescope was formerly known as WFIRST (Wide-Field Infrared Survey Telescope). The name is because it can cover the area of the sky much wider than the Hubble about 100x larger or more area of the sky at once as we discussed above. It is of highly desire to observe the time with Roman telescope. A most of the time is going in observation in covering the wide range of patch of the sky but still they manage to seize the time for the proposal of significant observation. An astronomy community suggests that observing the Roman ultra-deep field like the Hubble ultra-deep field is on the top priority as it provides many benefits.
In 237th meeting of American Astronomical Society Anton Koekemoer an astrophysicist at Space Telescope Science Institute gives the idea of Roman ultra-deep field for which he receives support of astronomers of more than 30 countries.
In a press release Anton Koekemoer said that by observing ultra-deep fields through Roman would provide compelling returns to the astronomical community just one needs to keep in minds about how one could take the advantage of Roman’s capability.
The difference between Hubble and Roman Space telescope is, the time taken for the observation by both the telescope is same of 100 hours the only difference it has Hubble used to take images of thousand galaxies and Roman telescope will take about images of millions of galaxies.
This deep images by the Roman allows the astronomers to boost their study and to observe the ancient galaxies that are grouped together, their star’s formation and ages etc.
Koekemoer said that Roman is also in team work with NASA’s James Webb Space Telescope and others to work in space and on ground. Telescopes, these days are providing larger amount of detailed data as they are becoming more powerful and to deal with those data scientists are developing their many ways like machine learning and AI. There is also another powerful telescope called Vera C of Rubin observatory which gives massive amount of data to scientific community to get prepared in advance. To deal with those massive data Northwestern University have started a program to educate the new data scientists.
These telescope is also used to design the simulations of universe based on the data. Scientists use supercomputers to create the simulations of how universe has developed over time and also these data based simulations shows that after the big bang i.e. between 800 million and 1 billion years how galaxies have started growing up. Roman will then observe these galaxies to compare them with the simulations.
To cover the period between 500 million years and 3 billion years after the big bang cosmologists used the term Cosmic Dawn and the Cosmic Noon to know about how the stars were born at much faster pace than now and also imagine about the supermassive black holes active at that time.
You can see the image of Nancy Grace Roman telescope primary mirror. Roman Space Telescope is so powerful that it can also boosts the research in exoplanets to check if their solar systems are like us or not.
