Do aliens exist? Are we not alone?

What are aliens?? Do you believe that aliens actually do exist? 


Well it’s been an quite interesting question in our minds that do aliens share the universe with us?? and i know your answers must lie between “ MAY BE “ or a straight “NO”.

When I was in school, I’ve heard my science teacher saying that “if you can imagine it, it does exist”, and yes, science  approves it well that reality is infinite and whatever you can think of does exist somewhere, somehow in our limitless extra – dimensional universe.

so, if we can imagine of aliens somewhere in our multiverse, even it can be possible.as we can see that in our known universe , at least 1010 galaxies like ours exist and if we take the lowest probability, a minimum of 100s earth like planets  and many more civilizations could exist. But we also know that universe is expanding day by day which increases the probability even more. So this would clearly be a big NO’ NO’ to say that we are alone and it would not be a surprise if there would be another life.

Let’s turn out to a recent mind – blowing discovery of NASA in cosmology. Last week of Feb, 2017 was historic in the search of extrasolar planets. ASTRONOMERS ARE CELEBRATING A NEW DISCOVERY. FINALLY, WE’VE FOUND SEVEN ROCKY EARTH SIZED PLANETS WHICH ARE ORBITING A STAR WHICH IS NOW KNOWN AS “TRAPPIST” and like our solar system this seven planetary system (named from 'b' to 'h' ) is known as “TRAPPIST 1” system.

This is the very first time that after our solar system, some other planets have been discovered revolving around a particular star (TRAPPIST). This TRAPPIST is actually a red dwarf star. It only has about 8% of the mass and 11% radius of the sun and is found located 39 light years away from us.
In 2016, Trappist found only two planets but now in 2017, NASA’s SPITZER SPACE TELESCOPE discovered another five in addition.

NASA’s are beyond excited at the discovery of incredible star system as three out of those seven planets are present in “habitable zone” which means there could be liquid water on the surface and so the most likely chances for finding alien life there goes high.
Using Hubble space telescope, SCIENTISTS have already checked for heavy hydrogen envelope around the newly discovered seven planets as the heavy hydrogen atmosphere could have lowered the chances of habitability by trapping greenhouse gases, but they didn’t found such. Now, also this is a positive sign for searching some form of life there.

Well interestingly, these seven planets are pretty close to each other that standing on one planet one can see the geological features of the next planet and that close to their star that they used to complete one revolution around the star in 1.5 to 20 earth days, which means you can celebrate your birthday every 1.5 to 20 earth days..

Till date we’ve just discovered our sister star system, but surely in future years, we can expect to know a lot more about these planets and if there exists life, it can take a decade, says astronomers…


 ..but till then… We have to wait!!
