SENDING MUSIC TO SPACE FOR THE ALIENS TO HEAR: EVERYONE CAN BE PART OF SETI’S LATEST ENDEAVOR

Since the beginning of our space missions, humans have tried to send messages to aliens, messages that could- in that shortest lightest way possible – tell them who we are.

But, ‘What to send?’ has always remained a crucial question. Should it be a donut or masala dosa, showing them the delicious food we eat? Or, our collective wisdom in the form of texts, showing them what we all believe in?

This problem is, all this might be subjective – different food from different regions, different believes of different people. However, there is one thing that we all share, irrespective of borders, religions and varying culture – music,

For years, space agencies have collected sounds which can be sent to outer space. The Voyager golden records, which were launched in 1977, contain sounds and images selected to portray the diversity of life and culture on Earth, including the “Bhairavi: jat Kahan Ho” by Kesarbai Kerker, that late Indian classical vocalist.

Now, a composer plans to compile a ‘world song’ to send into space. Felipe Perez Santiago, Mexican musician and composer- in residence at the search the extraterrestrial intelligence (SETI) institute, has devised the “earthling project” along with Jill Tarter, the co-founder of SETI.

The project is a call to people everywhere to upload snippets of song that he plans to mould into collective human chorus. Santiago told the economist that the music is intended to be not a just message to the universe, but a mirror – a chance to say “see, we’re all the same.”

This summer, an initial composition as containing as many as ten thousand unaccompanied voices will be launched into the space, inscribed alongside Wikipedia and the Rosetta project, sampling of 1,500 human languages, on a nearly indestructible disc.

Jill Tarter, the co-founder of SETI, says that the programme aims not just to communicate with remote civilisations. It is also remind humanity of its own modest, fragile place in the cosmos.

ASTRONOMERS HAVE FOUND A SOLAR SYSTEM WITH SIX STARS AND SIX ECLIPSES

Our earth is a part of the solar system, were planets revolve around a star (sun). But what if there was a system with more than one stars? Think six!

Using data from NASA’s transiting exoplanet survey satellite (TESS), which is designed primarly to find exoplantes, Scientists have observed a system known as TIC 168789840, located 1900 light years away. This system consists of three binary pairs of stars.

The binary pair of stars is formed when two stars revolve around the same center of mass, in this case, there are three pairs in just one system, imaging waking up to two sun’s and four other very bright stars dancing around in the sky!

Even though a handful of other sextuplets have been discovered in the past, this is the first in which the stars within each of those three pairings keep crossing each other and eclipsing the other member. In other words, Scientists have found a sextuply eclipsing sextuple star system.

The question now arises, if there could be possible exoplantes in these systems. Four of the six stars orbit so close to one another that they immediately engulf any exoplantes that form near them, so the chances of any extraterrestrials around them are pretty slim.

However, the other two stars keep their distance. So it’s technically possible that there could be some exoplantes orbiting them and watching the other two binary systems from afar.
