How Planets May Be Seeded With the Chemicals Necessary for Life

Analysis of unique “fingerprints” in light emitted from material surrounding young stars has revealed “significant reservoirs” of large organic molecules necessary to form the basis of life. Dr. John Ilee, Research Fellow at the University of Leeds who led the study, says the findings suggest that the basic chemical conditions that resulted in life on Earth could ...

Coffee: The Essence of a Happy Life

The American writer Gertrude Stein (1874-1946) once said: “Coffee is a lot more than just a drink; it’s something happening. Not as in hip, but like an event, a place to be, but not like a location, but like somewhere within yourself. It gives you time, but not actual hours or minutes, but a chance ...

Some Planets May Be Better for Life Than Earth

Earth is not necessarily the best planet in the universe. Researchers have identified two dozen planets outside our Solar System that may have conditions more suitable for life than our own. Some of these orbit stars may be better than even our Sun. A study led by Washington State University scientist Dirk Schulze-Makuch, recently published ...

Could Life on Mars Exist Deep Underground?

Recent science missions and results are bringing the search for life closer to home. Scientists at the Center for Astrophysics | Harvard & Smithsonian (CfA) and the Florida Institute of Technology (FIT) may have figured out how to determine whether life on Mars, the Moon, and other rocky objects in the universe is — or ...

Surprising Number of Exoplanets Could Host Life

Our solar system has one habitable planet — Earth. A new study shows other stars could have as many as seven Earth-like exoplanets in the absence of a gas giant like Jupiter. This is the conclusion of a study led by UC Riverside astrobiologist Stephen Kane published in The Astronomical Journal. The search for life in outer ...

Living Life on Purpose: A Simple Guide

Live as if the current of life is taking you in whatever direction it is heading; surely, we all know someone who gives this kind of advice. Oftentimes, you measure only what’s in front of you: You get busy at work, deal with your stress or just sleep it off, do things out of habit, ...

Building Blocks for Life on Earth Arrived Later Than We Thought

Ancient rocks from Greenland have shown that the building blocks necessary for the evolution of life did not come to Earth until very late in the planet’s formation — much later than previously thought. An international team of geologists — led by the University of Cologne and involving UNSW scientists — have published important new ...

Scientists Develop New Method for Studying Early Life in Ancient Rocks

Scientists have developed a new method for detecting traces of primordial life in ancient rock formations using potassium. The method relies on searching for high concentrations of potassium in ancient sedimentary rocks, rather than traditional methods that look for carbon, sulfur, or nitrogen—which can appear in ancient rocks through processes unrelated to ancient life. University ...

Mars Terraforming Not Possible Using Present-Day Technology

Science fiction writers have long featured terraforming, the process of creating an Earth-like or habitable environment on another planet, in their stories. Scientists themselves have proposed terraforming to enable the long-term colonization of Mars. A solution common to both groups is to release carbon dioxide gas trapped in the Martian surface to thicken the atmosphere ...
