There could be a planet like our Earth at 16 light years ...

Since 1992, when the first extrasolar planets, or exoplanets (planets outside the solar system) were detected, 1,288 planetary systems have been discovered, with some 2,030 celestial objects that could be considered as planets.Most of these objects are closer to Jupiter than to Earth, both in terms of size and composition, as they are usually gaseous, like the four great planets of our solar system.

The search for planets outside our planetary system is oriented to an eventual identification of objects similar to Earth, both by location and size and composition, and we may be about to find one at a relatively close distance.

There could be a planet like our Earth 16 light years away...

A team of astronomers coordinated by Suman Satyal , of The University of Texas is studying a planetary system of the state Gliese 832 , a red dwarf with half the size of our sun, located 16 light years away and with two planets orbiting it: Gliese 832b , a giant Jupiter-like gas; and Gliese 832c , which could be a super-earth, a very large rocky planet.The first is 3.54 AU of its sun, and the second at 0.16 AU.The UA, or astronomical unit, equivalent to the distance between the Sun and the Earth, and a planet like our Earth, potentially speaking, with life and water in a liquid state, would have to be 1 or 2 AU from a star with characteristics similar to our sun.

There could be a planet like our Earth at 16 light years ...

And it is in that direction that Suman Satyal's team points, as it has been published in an article published in the magazine arXiv.org .Studying data on the orbit and behavior of 832b and c, and performing computer simulations, they have estimated that there should be a planet like our earth in an orbit that could have favorable conditions for life.This planet would be between the two already discovered (832b and 832c), it would be rocky and it would have 15 times the mass of the Earth.This hypothetical planet could be between 0.25 and 2 AU of the red dwarf.

We will have to wait for new astronomical observations around this solar system, before we can announce with certainty the existence of a sister planet “only” 16 light years from us.The quotes are not free, because it is a relative proximity , given that with current technology it would take 120 thousand years to arrive with a manned ship, and with the mini probes of the “Starshot” project, promoted by Stephen Hawking, it would be a one-way trip of 80 years .

But it would still give much to think about the existence of a planet with life possibilities so close to the Earth.It is possible that in 100 years the human being will begin the planetary move, Do not you believe it? Stay a little longer with us reading if it is possible that there are more undiscovered planets in our own solar system.

15 things your dog should NOT eat

There are toxic foods that your pet should never eat, at the risk of seriously affecting their health, as we explained in a previous article, however, we want to further expand the information so that Know what things to give and not to your dog and why. 15 things your dog should NOT eat EVER Two veterinarians, Richard Goldstein from the Animal Medical Center and Pamela Edwards from the Esperanza Veterinary Clinic, both in New York, give a list of those things your dog should never eat. 1.Seeds and heart of apples Both the seeds and the heart of an apple cause dilation of the pupils, difficulty breathing and make the mucous membranes bright red.

3 Psychological experiments that went too far

Scientific knowledge and its tactics, as we conceive them today, has evolved throughout history, but in this long road, based on experimentation, not everything has been successful even leading to true tragedies as happened in the following psychological experiments. 3 Psychological experiments that went too far Little Albert The first of these rugged experiments is the one that took It was conducted in 1920 and was directed by Dr. John B.Watson of Johns Hopkins University, which sought to certify the Classic Conditioning by which the behavior of a subject through “learning by association”.That said it does not sound bad at all but to prove this theory, Dr.Watson used a baby of only 11 months, who like any baby did not have prejudices with animals, which scared again and again with strong metal strokes at the same time that showed an animal until totally traumatize the child, that after the experiment, he suffered a phobia towards anything that had hair.

What is the Big Bang theory?

What is the age of the earth? What are black holes like? Can you travel through them? There are many times that in Science Daily Online we have asked ourselves about the universe.This time we want to talk to you about the origin of it, about the Big Bang theory . The expression " Big Bang " means Big Bang.About 15 billion years ago there would have been a huge explosion that released enough matter to originate the Universe . According to this theory, everything that exists was ever concentrated on a smaller point in dimensions than an atom and, when the explosion , I release an impressive amount of energy .As of this initial explosion, the Universe began to cool and expand, until ten million more years later they would have cooled enough to consent to the formation of atoms that later joined, thus forming the first s galaxies. Via Lactea photographed from the United Kingdom From this possible revelation, it is estimated that when the Universe complete...
