The colors of the ice exoplanets can betray life forms

The determination of reliable life signatures will at least allow one to think that an exoplanet hosts life forms similar to those known on Earth. Take, for example, the presence of large volumesOxygen In L ‘Atmosphere Exoplanet is a rock the size of our blue planet. Should we conclude that it is populated by photosynthetic organisms that produce oxygen? Cyanobacteria Can be found and created on earth Stromatolites Of Hemelin Pool In Australia?

Unfortunately not, because we know it is a significant photosynthesis Molecules Water can create such an atmosphere that it actually resembles an extraterrestrial being where water is Liquid Largely hidden As explained to Futura, astronomer Frank Celsius encourages us to be very careful about the concept of life signature.. So exobiologists know that it will probably take decades of observational studies and many more to model the atmosphere. ExtraterrestrialsThanks to the telescope for example James WebbBefore gaining moderate confidence in the suitability of some biological signatures that have not yet been discovered, perhaps it is a combination of the detection of multiple molecules.

This video begins with a series of general public studies on exobiology. Are we alone in the universe? You may have already asked yourself the question … We can find answers in movies, literature or science fiction comics, and our imagination is full of extraterrestrial beings! But what does science say about this? The AstrobioEducation site invites you to discover exobiology, an intermediate science that aims to study the origin of life elsewhere in the universe and its research. Through an educational journey divided into 12 stages, researchers from various fields will help you understand how it helps to answer fascinating questions about the origin of life outside the Earth and its research. © French Society of Exophology

Lessons from the Arctic and Antarctic for Exophology

But keep in mind that nothing prevents them from exploring and proposing potential biological signatures, while at the same time being very open to criticism and that their findings should be linked to more healthy skepticism in the future. It is in this critical state of mind that we should take an article published in the magazine AstronomyAnd we are committed to an international team consisting of researchersInstituto Superior de Acronomia y Technico Laval University of Canada in Portugal, Quebec and Cornell University in the United States.

We can still hope that the biographical signatures proposed in this article will be explored on Mars in the next two decades and will soon be tested. Moons Ice Thursday And Saturn, Europe and Enceladus. In fact, the researchers were impressed by the colors of the colonies Microbes Let us examine the subarctic conditions of Hudson Bay, Canada.

In fact, for decades we have been inspired by the study of life forms in icy and rocky environments.Arctic AndAntarctic Define Strategies for Finding Life on Mars The article published today will no doubt have caught the attention of adults External biologist Carl SaganSo this technique only converts to ice exoplanets in a certain way.

Per Aspera at Astra – The Mars 160 Mission The seven-minute film was created by the Mars Society to take a closer look at long-running surface simulation projects on Mars. Mars Desert Research Station (MDRS) in southern Utah and Flashline Mars Arctic Research Station (FMARS) in Northern Canada. The film revolves around the recently completed Mars 160 double voyage that took place at MTRS in 2016 and then at FMARS in 2017.

List of colors for 80 microorganisms

On Earth, vibrant biological colorsArctic Marking life signatures in small frozen spaces முக்கிய, explains the main author of the article published in AstronomyLígia F. Coelho, Ph.D. Carl Sagan From the kernel (CSI).

The researcher added in a press release from Cornell University: ” The colors of the creatures can dominate the entire surface of the icy worlds. Frozen exoplanets are not the cause of loss. With future binoculars, you can see the telltale signs of germs – if you know what you want to see.

He, along with his colleagues, made a list of colorful signatures made by Sample 80 microbes Gujjurabic in Quebec on ice and water, but at the mouth of the Great Whale River.

Having the right tools to detect life forms in icy worlds is fundamental Zida Martின்nez Mart இயக்குனர்nez, director of the Astronomy Laboratory, explains Instituto Superior de Acronomy and Technico Who came up with the idea for this research Lisa Caldenecker, director of CSI, notes: ” Studies show that biological signatures are more intense in arid environments, and that having drier locations and microbial life patterns than Earth could indicate better targets for future space travel. “.

Measurements were made in the laboratory of William Bilbot, a professor at the School of Civil and Environmental Engineering in Cornell, to determine how these microbes would visualize our telescopes.
