Ancient Diamonds Show Earth Was Primed for Life’s Explosion of Diversity at Least 2.7 Billion Years Ago

Posted by in categories: alien life, chemistry

A unique study of ancient diamonds has shown that the basic chemical composition of the Earth’s atmosphere which makes it suitable for life’s explosion of diversity was laid down at least 2.7 billion years ago. Volatile gases conserved in diamonds found in ancient rocks were present in similar proportions to those found in today’s mantle, which in turn indicates that there has been no fundamental change in the proportions of volatiles in the atmosphere over the last few billion years. This shows that one of the basic conditions necessary to support life, the presence of life-giving elements in sufficient quantity, appeared soon after Earth formed, and has remained fairly constant ever since.

Presenting the work at the Goldschmidt Geochemistry Conference, lead researcher Dr. Michael Broadly said, “The proportion and make-up of volatiles in the atmosphere reflects that found in the mantle, and we have no evidence of a significant change since these diamonds were formed 2.7 billion years ago.”

Volatiles, such as hydrogen, nitrogen, neon, and carbon-bearing species are light chemical elements and compounds, which can be readily vaporized due to heat, or pressure changes. They are necessary for life, especially carbon and nitrogen. Not all planets are rich in volatiles; Earth is volatile-rich, as is Venus, but Mars and the Moon lost most of their volatiles into space. Generally, a planet rich in volatiles has a better chance of sustaining life, which is why much of the search for life on planets surrounding distant stars (exoplanets) has focused on looking for volatiles.

Construction begins on the Square Kilometre Array

Posted by in category: alien life

The biggest ever radio telescope just started construction, and is scheduled to begin science operations in 2027. It will be 50 times more sensitive than any previous observatory, and 10000 times faster at gathering data. It will study the so-called Dark Ages (just 380000 years after the Big Bang), as well as large-scale galactic structures, and could even look for signs of alien life.


This week, construction officially began on the Square Kilometre Array – set to become the largest and most sensitive radio telescope ever built – with first light scheduled for 2027.

The lonely universe: Is life on Earth just a lucky fluke?

Posted by in category: alien life

Are there any individuals out there who, like myself, believe that our wonderful planet probably hosts the only lifeforms to be found anywhere? Should this ideed be the case, it places a colossal responsibility upon humankind. A responsibility, I would maintain, to not only share the gift of Earth-life with the silent, barren worlds which surround us but also to do our utmost to safeguard the splendid variety of life, in all of its myriad forms which inhabit our fecund and bountiful planet. If there are like minded folk out there please respond-I would like to link up with the view to working collaboratively. As this will be an extremely lengthy endeavour, probably lasting for many generations, my own area of interest is in popularising the subject among the young.


Life beyond might not exist — or we just don’t know how to find it.

New study disputes the theory of aliens living in the clouds over Venus

Posted by in category: alien life

If microbes live in the Venusian skies, they must be able to survive with far less water than any known life found on Earth.


If there are microbes living in the Venusian skies, they have evolved to survive with far less water than any known life on Earth, a new study suggests.

Is Intelligent Life As Uncommon As ‘Rare Earth’ First Proposed?

Scientists now have some ultra-prime targets to look for aliens

Would anyone have concluded that there was intelligent life on Earth 900 years ago?


A new study found a list of stars that could directly see Earth. And at least seven of them have known habitable planets.

Scientists count more than 1,700 star systems with a view of Earth

Posted by in category: alien life

Scientists say in a new report that 1715 star systems have been in a position to view Earth over the past 5000 years.

According to the report published Wednesday in the journal Nature, the study could provide clues on where to look for extraterrestrial life that could have a view of Earth.

The authors wrote that while there has been much research on the position of stars, previous studies did not take into account how the view from star systems has changed over time.

The Four Stages of Intelligent Matter That Will Bring Us Iron Man’s ‘Endgame’ Nanosuit

Posted by in categories: alien life, cyborgs, nanotechnology, robotics/AI

Imagine clothing that can warm or cool you, depending on how you’re feeling. Or artificial skin that responds to touch, temperature, and wicks away moisture automatically. Or cyborg hands controlled with DNA motors that can adjust based on signals from the outside world.

Welcome to the era of intelligent matter—an unconventional AI computing idea directly woven into the fabric of synthetic matter. Powered by brain-based computing, these materials can weave the skins of soft robots or form microswarms of drug-delivering nanobots, all while reserving power as they learn and adapt.

Sound like sci-fi? It gets weirder. The crux that’ll guide us towards intelligent matter, said Dr. W.H.P. Pernice at the University of Munster and colleagues, is a distributed “brain” across the material’s “body”— far more alien than the structure of our own minds.
