Fascinating discovery: 3 Exoplanets have been discovered orbiting a dwarf star


The universe will never cease to fascinate us with its amazing phenomena. In the earth’s quest for alien life, are we surprisingly close to a life altering revelation from the infinite cosmos? In an amazing new phenomenon recorded 40 light years away from earth, the discovery of three exoplanets orbiting a dwarf star has amazed and astonished researchers for its profound significance. The discovery has finally given scientists evidence of their theories that somewhere out there in the infinite universe, exoplanets like earth do exist orbiting low mass stars with decreased temperatures.

The phenomenal discovery which was reported in the Nature Journal observed that the planets were similar in size to the earth and Venus. That’s not all! These are the most suitable planets which may harbor alien life!

1 The First Place to Look For Alien Life

According to team leader of the research, Michael Gillon of the Liege University, Belgium, these little solar systems orbiting tiny stars are perhaps the only exoplanets capable of supporting life and technology similar to earth. These planets should be the first place to commence a search for alien life.

What is most surprising about the study is the fact the researchers stumbled upon the amazing discovery of three exoplanets by accident. The actual observational study was being conducted on TRAPPIST-1, an ultra cool dwarf star located in the constellation of Aquarius.

2 A Milestone in the Quest for Life beyond the Solar System

The international teams of researchers were making preparations for a large astronomy project using a powerful and new telescope located in the Chile Observatory. Instead what they found astonished them beyond belief. The remarkable discovery of three exoplanets orbiting TRAPPIST 1 was a milestone in the search for life beyond our solar system.

TRAPPIST -1 has intensity a thousand times lower than the sun. This means it is a dim star the size of Jupiter. It was found existing in a much cooler part of the universe. Two planets were found orbiting TRAPPIST -1 at distances between 1.1 and 1.5 percent the distance between Earth and the Sun. The third planet was found at a further distance and researches assumed that it could be passing by the star between 4 to 72 days. The other two planets closer to the star passed by it every 1 to 2 days.

The estimated temperatures of the two exoplanets could be similar to Venus because of the reduced intensity of the star and the low quantity of photons emitted by it.

3 A Painstaking Discovery Involving Three Telescopes Worldwide

The research on TRAPPIST 1 was done through a 60 cm telescope in order to record its intensity and brightness. The observation was painstaking as it involved recording its brightness every 1.2 minutes that lasted 245 hours over 62 nights. The telescope then sensed a dimming of the star and it was this observation that suggested a celestial body was continuously passing by and hence the periodic blocking of light. When researchers noticed this, they introduced three larger telescopes into the study. Telescopes located in India, Chile and Hawaii were pressed into action and it was this that led to the discovery of three exoplanets orbiting the star.

Researchers utilized every resource of technological expertise to pinpoint the positions and nature of the amazing exoplanets orbiting TRAPPIST 1.

4 Does Life Exist or Not, You’ll Just Have to Wait and See

Further research on the exoplanets is all set to commence using the powerful Chandra 2 meter telescope in Ladakh, India and the James Webb space telescope which will commence operating in 2018. Researchers will study the mass, composition and atmosphere of the planets. The research will be no less exciting as part of it will include finding evidence of bio signatures which will reveal whether life exists there or not. It also means we will all have to patiently wait for a revealing answer.
