2010 was a year in which many extrasolar planets were discovered with the help of powerful telescopes. Apart from the smallest planet, some big planets and an earth like planet were discovered in 2010. The hope for finding life forms in other exoplanets is increased a lot after the discovery of these discoveries. This paper briefly analyses the recent discovering of planets outside the Solar System using telescopes.
The factors, which forced or encouraged the human to look for planets outside the solar system is explained in this part.
- Extrasolar Planet or Exoplanet
The terms like Extrasolar planet and Exoplanet which represents the planets found outside the solar system are explained in this part
- Recent Discovering of Planets Outside the Solar System Using Telescopes
This section is the major body of the proposal. In this part recent discoveries of planets outside the solar system with the help of telescope are explained. This section explained the discovery of the smallest planet, the discovery of the planet-like earth, and some giant planets.
The present developments in the planet explorations and the possible future developments were concluded in this part.

Only after science and technology began to grow quickly did the thirst for learning more about our world develop in the minds of humanity. In the past humans had very little understanding about our world and our earth, yet when research continued to discover the secrets of the universe, humans began to dream of discovering life on other worlds, one after another. In the solar system, they began to investigate further into other worlds and the likelihood of life occurring there. Yet so far, owing to the harsh environmental conditions there no planets in the solar system seem to have life types. In the worlds of the solar system, the inability to locate life forms compelled man to look beyond the limits of our solar system in pursuit of life forms that have lately contributed to the discovery of several other planets.
Extrasolar Planet or Exoplanet
Planets located in the solar system are commonly referred to as extrasolar planets or exoplanets. With the assistance of indirect approaches such as radial velocity measurements and direct methods or direct imaging technology utilising strong telescopes, scientists have since detected about 500 such planets beyond the solar system. Compared to earth, the detected exoplanets were big and tiny in number. It has been statistically confirmed that a large amount of stars, including the sun, can have a planetary structure. In the nineteenth century, as physicists and technologists aggressively began their search of space to discover extraterrestrial existence with the aid of strong telescopes and other advanced scientific instruments, exoplanets became a topic of concern.
Recent Discovering of Planets Outside the Solar System Using Telescopes
On September 30 2010, Paul Butler and his colleague Steven Vogt of the University of California at Santa Cruz, “announced the discovery of a rocky planet in another solar system that has the most basic and essential conditions needed to support extraterrestrial life” (New Earth-like planet outside solar system found). “According to Steven Vogt, the chances of life on this planet are 100%” (First Habitable Planet Outside Solar System is Found). Even though the presence of earth like planet in the universe have been predicted long before, this is the first time scientists was able to verify the presence of an earth like planet physically. The above planet is named as Gliese 581G and it is around 20 light years distant from earth or solar system. Scientists expects that the water presence in this planet and that also in liquid form. It is assumed that six or seven planets are orbiting in circular orbits along with Gliese 581.
SATTER and JORDANS (2010) have mentioned the discovery of “a sun-like star with as many as seven different planets — including one that might be the smallest ever found outside the solar system” (SATTER and JORDANS). The above planets were discovered around the star HD 10180which is more than 100 light years distant from earth. Many scientists believe that the above discovery is a strong indication that our universe consists of full of planets and many of them could be similar to that of our own.
In 2010 itself an international team announced the discovery of seven new planets outside our solar system. “The planets were discovered using the sophisticated CoRoT (short for convection, rotation, and planetary transit) telescope that was launched in December 2006 by the National Space Studies Center in France, CNRS French Laboratories, several other European partners, Brazil, and Israel” (International Team Discovers Seven New Planets Outside Our Solar System). The above planets were discovered with the help of measurement of the black spots created as each planet passed in front of its sun. Like the planets in our solar system all the other planets discovered so far is orbiting around their sun and while they meet their sun face to face some black spots were created which is recorded or measured by the giant telescopes used by the scientists.
On May 1, 2010, NASA scientists announced the discovery of five giant new planets outside the Solar System with the help of their new telescope, Kepler.
Launched from Cape Canaveral on 6 th March last year, Kepler was designed to scour the Universe for evidence of planets with characteristics similar to those of Earth, so that one day Mankind might have a safe haven in 7.5 billion years time when our Sun explodes, that is if he has not destroyed the planet himself long before that. The latest discovery was announced in Washington on May 1, 2010, at a meeting of the American Astronomical Society and has been confirmed by terrestrial stations linked to Kepler (5 New Planets Discovered )
The discovery of new planets in recent times has increased our hope of finding life forms in other planets outside our solar system. Earlier we confined our explorations in the solar system alone whereas the development of advanced technologies and equipments like powerful telescopes made us capable of looking beyond the limits of solar system for life forms and other planets. The exploration outside of the solar system of new worlds raised our hope million times in finding life forms in other planets and the evidences collected so far has many positive signs about the presence of life forms in planets outside the solar system.
