Organic Matter on Mars was formed from Atmospheric Formaldehyde

Posted by in categories: alien life, chemistry, evolution

Researchers have developed a Martian atmospheric evolution model to propose a new theory about Mars’s past. Although Mars is currently a cold, dry planet, geological evidence suggests that liquid water existed there around 3 to 4 billion years ago. Where there is water, there is usually life. In their quest to answer the burning question about life on Mars, researchers at Tohoku University created a detailed model of organic matter production in the ancient Martian atmosphere.

Organic matter refers to the remains of living things such as plants and animals, or the byproduct of certain chemical reactions.

Whatever the case, the stable carbon isotope ratio (13C/12C) found in organic matter provides valuable clues about how these building blocks of life were originally formed, giving scientists a window into the past.

Formation of Super-Earths is Limited Near Metal-Poor Stars — New study may help the search for life beyond Earth

Posted by in categories: alien life, solar power

In a new study, astronomers report novel evidence regarding the limits of planet formation, finding that after a certain point, planets larger than Earth have difficulty forming near low-metallicity stars.

Using the sun as a baseline, astronomers can measure when a star formed by determining its metallicity, or the level of heavy elements present within it. Metal-rich stars or nebulas formed relatively recently, while metal-poor objects were likely present during the early universe.

Previous studies found a weak connection between metallicity rates and planet formation, noting that as a star’s metallicity goes down, so, too, does planet formation for certain planet populations, like sub-Saturns or sub-Neptunes.

Follow The Salt to Find Life on Mars

Posted by in category: alien life

We may be looking for Martian life in the wrong places. The Viking life detection experiments might have inadvertently killed indigenous Martian life by applying too much water. Instead we should “follow the salt” to find life on Mars! See my blog on BigThink (with link to Nature Astronomy paper), Weblink through my webpage:

Strong Solar Flare Erupts from Sun

Posted by in category: alien life

The Sun emitted a strong solar flare, peaking at 6:20 p.m. ET on Oct. 1, 2024. NASA’s Solar Dynamics Observatory, which watches the Sun constantly, captured an image of the event.

Solar flares are powerful bursts of energy. Flares and solar eruptions can impact radio communications, electric power grids, navigation signals, and pose risks to spacecraft and astronauts.

This flare is classified as an X7.1 flare. X-class denotes the most intense flares, while the number provides more information about its strength.

From Lab to Cosmos: Rethinking Signs of Life on Other Planets

Posted by in category: alien life

When it comes to searching for life beyond Earth, specifically on exoplanets or exomoons, are researchers searching for the correct biomarkers? This is what a recent study published in The Astrophysical Journal Letters hopes to address as an international team of researchers investigated how certain organic compounds that were long hypothesized to be created by life can be created in a laboratory setting without life present. This study holds the potential to challenge longstanding hypotheses regarding what biomarkers scientists should search for when trying to identify life on other worlds and how we should adapt our search methods accordingly.

For the study, the researchers successfully created dimethyl sulfide, which is an organic sulfur compound typically produced by marine algae, using a combination of light and gases that have been identified in the atmospheres of exoplanets. The caveat is no organisms were present to create the dimethyl sulfide, which left the researchers puzzled due to the longstanding hypothesis that marine organisms were the only way dimethyl sulfide was created.

“The sulfur molecules that we’re making are thought to be indicators of life because they’re produced by life on Earth,” said Dr. Eleanor Browne, who is an associate professor in the Department of Chemistry at the University of Colorado Boulder, and a co-author on the study. “But we made them in the lab without life — so it might not be a sign of life but could be a sign of something hospitable for life.”
