Six exo-planets are circling red dwarf star Gliese 581 20 light-years distant in the constellation Libra
Astronomy News – The human search for an exoplanet capable of being a cradle for a new human genesis found what many consider the first exoplanet with the physical makeup to make it possible. A team of planet hunters from the University of California (UC) Santa Cruz and the Carnegie Institute of Washington recently announced to the world the discovery of an exoplanet they believe has a few characteristics of an exoplanet with the right stuff to make life possible. Gliese 581g, as it’s referred too, has about three times the mass of Earth and appears to be situated in the right spot in the solar system of the red dwarf star Gliese 581 for the ingredients of life to exist. This is about dead center in what planet scientists term the habitable zone of Gliese 581, a position planet scientists believe could make it possible for water and an atmosphere to exist on this exoplanet, necessary ingredients for the formation of life, planet scientists believe.
Astronomers search for a cradle for a new human genesis
These planet hunters have been using one of the largest time-machine-to-the-stars on the planet, the Keck I Telescope in Hawaii’s W.M Keck Observatory, to journey 20 light years to the constellation of Libra to continue the search for more planets circling red dwarf star Gliese 581 that could be habitable. Planet hunters have been using the HIRES spectrometer to precisely measure the radial velocity of the host star – the motion of the star along the line of sight from Earth – and stars close to red dwarf star Gliese 581, in order to try to find other planets circling this red dwarf star. The gravitational pull of orbiting planets causes periodic changes in the radial velocity of the host star that astronomers can calculate using sophisticated mathematical techniques we’ll cover on another day. These are the techniques planet hunters used in order to find all of the stars they have found circling red dwarf star Gliese 581, which after the two most recent planet discoveries, brings the total to six exoplanets circling this distant star.
Astronomers believe Gliese 581g is in the habitable zone of its home star
The discovery of six exoplanets circling red dwarf star Gliese 581 marks the high-planet mark for the human hunt for planets capable of being a cradle for a new human genesis. Gliese 581g is the only planet of the six exoplanets discovered that astronomers have indicated, so far, as being in the life zone of the red dwarf star Gliese 581. This exoplanet orbits its parent star in about 37 days and measurements planet scientists have made of its mass indicates it’s probably a rocky planet with a definite surface and enough gravity to hang onto an atmosphere. Gliese 581g is also tidally locked to its parent star, which means that one side of the planet is always facing its host star and in perpetual daylight. This makes some planet scientists believe that the best place for life to exist would be in the terminator, the part of the planet between the day and night sides of the planet.
Could a Cradle For a New Human Genesis be found in Our Solar System?
Earth is quickly becoming a less hospitable place for human life
Astronomy News – The search for another home to act as a cradle for a new human genesis has turned another page today. Two papers analyzing the chemical activity reported by observations made by NASA’s Cassini Orbiter of Saturn’s moon Titan report the data is consistent with the possible presence of theoretical methane-based life and how such life forms existing in an exotic and dynamic environment could affect their surroundings.
The first paper is available online and in the August edition of Icarus and was authored by Darrell Strobel of Johns Hopkins University. This paper describes a flow of hydrogen molecules through the atmosphere of Titan that disappear at the surface. “It’s as if you have a hose and you’re squirting hydrogen onto the ground, but it’s disappearing.”
The second paper is also available online and will appear in a future issue of The Journal of Geophysical Research. This paper reports a lack of acetylene and an abundance of organic compounds on the surface of Titan. This implies that Titan could be a place in the solar system where dynamic organic chemistry is currently taking place, and Titan could be a possible place in our solar system where the elements could exist for a home to act as a cradle for a new human genesis.
This news in no way means they have found life on Titan, but it does strengthen the case for the possibility of life taking more forms and existing in environments beyond those envisioned by humans. The scientists releasing these studies can certainly be applauded for keeping an open mind to the possibility that life exists beyond the bounds set by human imagination. We should keep in mind that chemical processes can also explain the data collected by the Cassini Orbiter and this is certainly a much simpler explanation for a flow of hydrogen molecules through the atmosphere of Titan that disappears at the surface. Indeed, hydrogen would seem to be the element of choice to consume in life processes on Titan. We should probably exhaust all other possibilities, before suggesting there the result of life processes, though, and save the existence of life for the last conclusion.
Astronomers are currently busy looking for a cradle for a new human genesis
The search for a new home for human life has started
Astronomy will be the next great science
Astronomy News – The search for planets capable of acting as a cradle for a new human genesis has begun. Astronomers are searching the night sky above you for planets circling distant stars within what space scientists refer to as a stars life-zone or habitable-zone. This zone is at an orbital distance from a star allowing for the formation of the elements necessary for Earth-based life to exist. In the search for planets capable of supporting Earth-based life, astronomers are mainly looking for water.
Only looking for planets with the elements we know can support Earth-based life could be putting human-made limitations on the search for habitable planets and the creation of life that will prevent us from seeing the whole picture. Life-on-Earth has always shown itself to be adaptable, unpredictable and totally uncontrollable, and the environments life could evolve in are probably beyond current human imagination. Space scientists conducting computer simulations of planetary systems indicate that the variables that determine the life-zone of a star and its suitability for human life are just being studied and discussed. Water could exist in a usable form for the creation of life during specific periods of time on a planet’s surface for Earth-like planets close to a Jupiter-size planet orbiting in a highly elliptical orbit. A description that fits many of the exoplanets discovered, so far, space scientists note.
Planets with the necessary ingredients to support human-based life are hard to find
A highly perturbed orbit could result in an Earth-like planet experiencing long time-periods of freezing and heating temperatures, with a period of ideal weather for the creation of life, squeezed in between. Hardly the ideal situation for human life and this simulation is only one of the possible exotic habitats we could find on our “Journey to the Beginning of Space and Time”. Human life could be walking on planets in the centuries ahead where the length of a day varies wildly, the seasons are unrecognizable, and the year just seems to go on forever.
The crazy zoo-of-planets astronomers are discovering in the night sky is threatening to break the human-made shackles we have attempted to put upon them. The environmental conditions on one or some of these planets could one day provide the elements for a new human genesis that could shatter the foundations of belief systems across planet Earth. Environments capable of supporting human evolution and the development of higher life forms? Astronomers and space scientists have taken another step forward to discovering an answer to this question and astrobiologists are currently continuing the search for a second-Earth for humankind.
