Take a “Journey to the Beginning of Space and Time” and view exoplanets that might be more like death-planets for humans
Surviving space is going to be hard
Astronomy News – Planets circling twin stars close in proximity could be a real tough place for life to begin, according to the conclusions of a study conducted using data from NASA’s Spitzer Space Telescope. Space scientists using NASA’s infrared observatory recently found what they believe to be clouds of possible dust around three mature, close-orbiting binary stars. Dust that scientists think is possibly the result of the planets orbiting these twin stars colliding, which could make living on these planets difficult for any lifeforms that might have arisen on these planets.
Planetary collisions are possible real-life science fiction in action, as the reasons for the dust clouds are certainly a matter of conjecture and something that any science fiction writer is going to be able to spin a tale of annihilation around. Lifeforms evolving under the environmental conditions that possibly exist on planets orbiting binary stars of the particular class studied would certainly be something beyond the imagination of any human writer. It’s unlikely that anything we humans create using our imaginations could ever match the possibilities that exist in space and time. The finite imaginations of humans are limited by our senses, experiences and the limits of what we refer to as our human perception or intelligence to some.
Lifeforms evolving on these planets would have to survive possible planetary collisions at regular intervals if space scientists conclusions are correct? If they have the ability to sense the world beyond their normal lives? Lifeforms existing on these planets could be non-sentient and unable to perceive the annihilation above them. They could be looking up at annihilation coming toward them in the form of another planet, asteroid, or other celestial body orbiting the binary star systems in question. They may have been destroyed in a recent collision between planets and are space dust, once again. The view would be a spectacular one, though, with two huge suns that would exceed anything we experienced viewing the double stars systems in the Star Wars Saga.
Humans will evolve on any new planet they inhabit
Life evolving on planets circling binary stars like the ones in question would have a limited time to evolve into a space traveling sentient race as well. The suns in the binary star system they have evolved on are slowly circling closer and closer, according to astronomers, which could possibly make surviving and evolving on these planets a lot more difficult. Lifeforms surviving and thriving on these planets would likely be a survivor beyond human imagination, so we should probably thank our lucky stars that they aren’t likely to be stopping by for a visit, anytime soon.
“Journey to the Beginning of Space and Time” to view the planetary zoo
Astronomy takes you to the far stretches of the universe in search of answers to the questions we all ask ourselves
Astronomy News – Space scientists looking at the rapidly expanding menagerie of planets being added to the planetary zoo keep coming back from their journey wide-eyed and smiling like a kid that just got the key to the candy store. The latest editions to the planetary zoo are orbiting celestial bodies in orbits totally out-of-whack with the orbits of planets previously viewed in the universe. In fact, astronomers are bringing planets to be housed in the planetary zoo, of late, that are so different space scientists are having to rethink present theories on exoplanets circling distant suns in the Milky Way.
Astronomers studying three known Jupiter-size exoplanets circling dwarf star Upsilon Andromeda A, which lies about 44 light-years from Earth, have determined these exo-planets are circling in orbits unlike any seen before by Earth astronomers. Orbiting at steep angles to one another, these three planets could have exotic environments and global systems, unlike anything humans can imagine. The possibilities of life existing in star systems with such potential for chaos is going to entice the imaginations of science fiction writers across the planet to create realities and scenarios sure to entertain and create fear in the human heart.
Astronomers studying planets are discovering things we never even guessed at
The theories of space scientists concerning the formation of planetary systems will have to be altered with the arrival of these new and unexpected members of the planetary zoo. The possible scenarios for the formation of planetary systems will have to be changed to include the possibility for the formation of exoplanets of this type. Possibilities that will now include the inward migration of planets orbiting distant stars, the ejection of planets from a system due to planet scattering, or the disruption of the planetary system due to gravitational interaction with Upsilon Andromedae A’s companion star, Upsilon Andromedae B.
One thing is for sure, the human “Journey to the Beginning of Space and Time” has taken a turn down a path that definitely isn’t heading to Kansas, Dorothy!
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.
