Researchers at Yale and Caltech have a bold new theory to explain how Earth transformed itself from a fiery, carbon-clouded ball of rocks into a planet capable of sustaining life.
The theory covers Earth's earliest years and involves "weird" rocks that interacted with seawater in just the right way to nudge biological matter into existence.

Right now, some 182 million miles separate the red clay of Alabama from the dusty red planet Mars. But groundbreaking flight hardware developed at NASA's Marshall Space Flight Center in Huntsville, Alabama, will soon close that distance.

Future tokamak fusion power reactors will generate heat beyond what current materials can withstand. Scientists have proposed various methods for cooling the edge of the magnetically confined fusion fuel, or plasma, to protect the walls of the surrounding tokamak. One approach is injecting impurities in the form of gases to help radiate away excess heat. However, there is a limited range of gase Dark energy: Neutron stars will tell us if it's only an illusion

A huge amount of mysterious dark energy is necessary to explain cosmological phenomena, such as the accelerated expansion of the Universe, with Einstein's theory. But what if dark energy was just an illusion and general relativity itself had to be modified? A new SISSA study, published in Physical Review Letters, offers a new approach to answer this question.

Using the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, researchers at Leiden Observatory in the Netherlands have for the first time detected dimethyl ether in a planet-forming disc. With nine atoms, this is the largest molecule identified in such a disc to date. It is also a precursor of larger organic molecules that can lead to the emergence of life.

The Amazon rainforest is likely losing resilience, data analysis from high-resolution satellite images suggests. This is due to stress from a combination of logging and burning - the influence of human-caused climate change is not clearly determinable so far, but will likely matter greatly in the future.

It had long been thought that the famous site of Stonehenge served as an ancient calendar, given its alignment with the solstices. Now, research has identified how it may have worked.
New finds about the stone circle's history, along with analysis of other ancient calendar systems, prompted Professor Timothy Darvill to take a fresh look at Stonehenge. His analysis, published in the journal Team chosen to make first oxygen on the Moon

Following a design competition, ESA has selected the industrial team that will design and build the first experimental payload to extract oxygen from the surface of the Moon. The winning consortium, led by Thales Alenia Space in the UK, has been tasked with producing a small piece of equipment that will evaluate the prospect of building larger lunar plants to extract propellant for spacecraft and breathable air for astronauts – as well as metallic raw materials for equipment.

The first NASA photographs taken on the Moon, including the first shot of an "Earthrise" and Buzz Aldrin walking on the surface, will be auctioned off in Copenhagen on Wednesday.
"One of my favourite photos from this fantastic collection depicts a photo of Buzz Aldrin taken by Neil Armstrong, and you can actually see Neil Armstrong being reflected in Buzz Aldrin's visor", Kasper Nielsen, the head of the Bruun Rasmussen auction house's valuation team, told AFP.
A total of 74 unique NASA photographs are up for sale, including 26 taken on the Moon during the Apollo missions in the 1960s and 1970s.
