The Roman Space Telescope will use two methods to detect exoplanets, including transit method and microlensing.
Roman Space Telescope (NASA)
The American Space Agency is working on several advanced telescopes to unravel the unsolved mystery of the NASA Universe. One such telescope is the Roman Space Telescope, which is to play a major role in the discovery of new worlds. It is expected that the Roman telescope will be launched by the middle of next year. After this, it will work to find the Super-Earth in the universe. Planets larger and larger than Earth are called super Earths.
The Roman space telescope will use two methods to find the exoplanet, including the Transit Method and Microlensing. Most telescopes use only one method. But the Roman telescope, using both methods, will be the best telescope ever to find the best planet. The most common method to find planets is transit method. It is believed that most of the Roman searches will be done through transit method. It is likely that this telescope will be successful in finding more than one lakh planets.
What kind of planets will the Roman telescope discover?
It is believed that the planets discovered by the Roman telescope will have three-fourths of the planets, which will be gas shells exactly like Jupiter and Saturn. Apart from this, some planets can also be cold ice balls, just like the planets Arun and Varuna present in our solar system. At the same time, some planets can be like small Saturn planets, which are four to eight times smaller than the Earth. It is likely that some of these planets are in the ‘Habitable Zone’ of their stars. Habitable zone is the area of any solar system, where the water on the existing planet remains in a liquid state and the surface of the planet is rocky.
… So this is why Roman telescope is special
The Roman telescope will cover the new celestial sphere and look farther than ever in our galaxy. It will be able to find planets up to 26,000 light years away. When compared to the Kepler Space Telescope, it is known that Kepler was able to study stars on average 2,000 light years away. Let me tell you that Kepler has now completed his mission. At the same time, the TESS telescope currently focuses on searching for planets about 150 light years away. Kepler and TESS as well as missions carried out by telescopes on Earth have discovered a wide variety of the hitherto investigated worlds in small regions of our galaxy.
