Antarctica’s Deception Island is the Perfect Place to Practice Exploring Mars

https://fed.brid.gy/r/https://www.universetoday.com/171031/antarcticas-deception-island-is-the-perfect-place-to-practice-exploring-mars/

<p>It’s not uncommon for space missions to be tested here on planet Earth. With the plethora of missions that have been sent to Mars it is becoming increasingly likely that the red planet was once warmer, wetter and more habitable than it is today. To find evidence of this, a new paper proposes that Deception Island in Antarctica is one of the best places on Earth to simulate the Martian environment. The paper identifies 30 sites on the island that correspond well to places on Mars.</p>

<p>The exploration of Mars has been a focus of space agencies worldwide, driven by the desire to understand the its geology, climate, possibility of past life, and excitingly the potential for future human colonisation. Early missions, such as NASA’s Mariner 4 in 1965, provided the first close-up images of Mars, while the Viking landers of the 1970s conducted the first successful surface experiments. In the 1990s and 2000s, orbiters like Mars Global Surveyor and rovers like Spirit and Opportunity helped us to understand more about the Martian terrain and atmospheric conditions. As we explore the red planet, and with more projects on the horizon, Mars remains a key target for exploration. </p>

Is Intelligent Life Inevitable?

https://fed.brid.gy/r/https://www.universetoday.com/170991/is-intelligent-life-inevitable/

<p>Biologists identified a series of “hard steps” on the journey from abiogenesis – that life evolved naturally from non-living matter – to modern civilisation. These steps, such as the evolution of multi-cellular organisms or even language make the stark suggestion that intelligent life is highly improbable! Instead, the researchers propose that human-like life could be a natural outcome of planetary evolution, increasing the likelihood of intelligent life elsewhere. </p>

<span id="more-170991"></span>

<p>The hard-steps model of the evolution of life suggests that the development of complex life depends on a series of highly improbable events, or “hard steps,” that must occur in a specific order. Each step marks a major evolutionary transition—such as complex cells, multicellularity, and intelligence. These steps are rare and require precise conditions, according to the theory, making complex life an unlikely outcome. This model explains why intelligent life seems so scarce, despite the vast number of potentially habitable planets, as the long timescales for each step contribute to its rarity.</p>

Efforts to Detect Alien Life Advanced by Simple Microbe Mobility Test

https://fed.brid.gy/r/https://www.universetoday.com/170901/efforts-to-detect-alien-life-advanced-by-simple-microbe-mobility-test/

<p>Finding alien life may have just got easier! If life does exist on other worlds in our Solar System then it’s likely to be tiny, primative bacteria. It’s not so easy to send microscopes to other worlds but chemistry may have just come to the rescue. Scientists have developed a test that detects microbial movement triggered by an amino acid known as L-serine. In lab testing, three different types of microbes all moved towards this chemical and could be a strong indicator of life.<br /></p>

<span id="more-170901"></span>

<p>The search for primitive alien life focuses on finding simple organisms, like microbes or bacteria that can survive in extreme environments. Scientists target places like Mars or moons of the outer planets like Europa (Jupiter,) and Enceladus (Saturn,) where liquid water and energy sources might exist. By studying extremophiles on Earth—organisms that seem to thrive in harsh conditions—researchers can gain clues about where and how to look for extraterrestrial life. Advanced technologies, including chemical sensors and microscopic imaging, are being developed to detect signs of life on future space missions.</p>

<p>One of the great challenges is exactly what to look for.

There are Places on Earth Which Could Have Life, but Don’t. What Can We Learn?

https://fed.brid.gy/r/https://www.universetoday.com/170609/there-are-places-on-earth-which-could-have-life-but-dont-what-can-we-learn/

<p>Don’t know about you but when I think of Earth my mind is filled with the diversity of life and the rich flora and fauna. In reality, about 99% of Earth is uninhabitable; deep underground places with high pressure and temperature where even the toughest bacteria cannot survive. There are places though where life thrives from tiniest toughest bacteria to the largest elephant. Then there are places that are habitable but devoid of life; lava flows are a great example and the space between microbes. A paper recently released looks at these uninhabited, habitable areas and wonders what we may learn as we search for life in the Universe.</p>

<span id="more-170609"></span>

<p>Life on Earth has taken millions of years to evolve to the state we see today and has invaded nearly every corner of the planet. That is, except those places where the environment is so extreme that even the toughest extremophile cannot survive. These regions include places like the Atacama Desert in Chile, one of the driest places on Earth, where rainfall is so rare that even microbial life struggles to survive. Similarly, parts of Antarctica’s dry valleys feature subzero temperatures, minimal liquid water, and high salinity in some soils, creating an environment hostile to most life forms. It raises interesting questions and perhaps pose limitations on life’s ability to survive. </p>
