The vastness and mystery of space has forever been an enchantment that has a great pull on many people. Space exploration is now considered to be the benchmarks for judging the technological advancement of any nation and the search for life in outer space has for long been an ongoing process! With the natural resources of Earth depleting at a rapid pace, astronomers have also been on the search for other planets hospitable for human conditions! At times there are some sightings by astronomers which get the whole space exploration community excited and we have now come across one such sighting! A planet the size of Saturn has been found about 35 light years away from Earth!
Reports state that an exoplanet the size of Saturn has been found orbiting a small, faint star, about 35 light years away from Earth. This planet was discovered after a radio telescope spotted a wobble in the star's motion! Interestingly, this is the first time that a radio telescope has been used to discover an exoplanet, using the 'wobble technique'! The wobble is said to be caused by the gravitational pull of the planet! This new planet was discovered by an international team of astronomers lead by the Max Planck Institute, by using a network of radio antennas linked together. This is called the Very Long Baseline Array (VLBA) technique! The star around which the newly discovered planet is revolving has been identified as an ultracool Dwarf, which makes it difficult to spot any planets around them as they are very faint!
However, the VLBA technique will help in discovering many more planets, even if they are revolving around such faint stars! A report state's that this discovery was possible only because of the high precision measurements of the faint star's position, which could happen only because of the radio telescope network! This new planet has been named TVLM 513 and has a mass similar to that of Saturn, with an orbit similar to that of Mercury, in our Solar System! This is the first discovery of an exoplanet with a radio telescope using this technique that requires extremely precise measurement's of a star's position in the sky! Though this technique has been known for long, it is very difficult to practically put in use! We hear that only a very few extrasolar planets with characteristics similar to TVLM 513 have ever been discovered so far! Stay tuned for updates...
