Exo moons or extrasolar moons are the natural satellites orbiting larger bodies throughout the cosmos, much like our own moon. So far, astronomers have discovered nearly 4,000 exoplanets outside our system, and the alien worlds are a major target for research. Scientists usually focus on earth-sized worlds at a so-called habitable distance from their host stars. However, an astrophysicist at the University of Lincoln, UK has told Express.co.uk that there may be a better candidate for the discovery of extraterrestrial life.
Dr. Phil Sutton of Lincoln's School of Mathematics and Physics performed computer simulations on the distant exoplanet J1
The researcher focuses primarily on how planetary rings – 200 times larger than those of Saturn – form and interact with giant planets.
And the next big question is whether these foreign worlds have the right conditions for the development of life.
Dr. Sutton said, "Exomoons are the best place for life."

Dr. Sutton said J1407b itself is about 400 light years away from our system – a distance of 2,351,450,100,000,000 miles.
Astronomers discover exoplanets most often, causing slight dips in the brightness of stars in the hope that these burglaries will be caused by the transition to the planet.
NASA's Transiting Exoplanet Survey Satellite (TESS) is leading the discovery of exoplanets using this method.

Exoplanets with rings, however, may show signs of gaps, and these gaps can be explained by the presence of exo-tons ,
These worlds can thrive outside the habitable zone
Sutton gives examples of such worlds in our own solar system, in which geographic aphic processes prepare the living conditions.
These are alien worlds like Jupiter's moon Europa or Enceladus in orbit of Saturn.

Dr. Sutton said, "These are frozen moons with several miles of thick ice sheets."
Exomoons are the best place for life.
But deep under the ice. There are huge oceans of liquid water where extraterrestrial microbes might exist.
How is this possible? Dr. Sutton said the secret lay in the gravitational influence of the respective gas giants of the moons.
Even though the planets and their exo moons are outside the habitable zone where temperatures are freezing, the tides caused by the planet's gravity are strong enough to heat up the frozen oceans.

Sutton, scientists could use this to compare the kinds of lives at the bottom of the Earth's ocean with what might lurk in the depths of those exomoon oceans.
But even if so, if that were the case, the astrophysicist said we still do not know what triggers the beginning of life 9003] Here on Earth, life in the oceans began about 3, 5 billion years ago and remained in the oceans until about a billion years ago.
Even though the conditions on the exo moons are correct, it is not clear whether the one spark that triggers the evolution of life exists – we simply do not know what it is.

There are other obstacles in the way, such as the proximity of one Planets to his stars.
Dr. Sutton said, "Planets very close to their stars are uninhabitable".
The problem is intense solar activity, such as solar flares strong enough to make planets inhospitable.
O n On Earth, magnetically charged torches of solar energy cause all sorts of problems, such as power grid fluctuations, geomagnetic storms and technical failures.
Exoplanets, much closer to their stars than we are, risk much more serious consequences.
But the astrophysicist said he was "hopeful," scientists would someday discover something in our own solar system.
Put simply, Dr. Sutton: "We want to find life".
And with the distance between our planet and It is currently inconceivable that we can reach an exoplanet with a space probe closest to the nearest star.
Reaching the speed of light would take four years to Earth's nearest star, Alpha Centauri A.
The best Chances are to send probes like Cassini and Huygens from NASA to explore our own system.
Dr. Sutton said, "I'd like to see another probe return to Saturn and Jupiter."
There are a lot of theoretical considerations working on exoplanets "are being carried out, and Dr. Sutton hopes to continue his research on ringed exoplanets and their moons.
How do astronomers find exoplanets in space?
According to NASA, there are five major ways in which astronomers track distant planets.
. 1 Beware of Wiggle: Orbiting planets cause stars in space to wiggle, changing the color of the observed light astronomers.
. 2 In search of shadows: A planet that passes right in front of a star can dim its light so far that it can be recognized from the earth.
. 3 Imaging Imaging: Astronomers can take pictures of palettes by removing the glare of the stars that surround them.
. 4 Gravitational microlenses: Traveling light from distant stars is easily bent by gravity as a planet moves between Earth and Star.
. 5 Astrometry: The orbit of a planet can cause a wobble in relation to the position of stars near the sky.
