Back then, a haze dominated by methane engulfed the atmosphere such that light could barely reach the ground, similarly to what can be seen today on […]

For the first time, a NASA spacecraft has detected matter from outside our solar system – matter that drifted from some other part of our galaxy right to us. This interstellar material was spotted by Interstellar Boundary Explorer (IBEX), a spacecraft with the purpose of studying the outskirts of our solar system from its orbit […]

The paradox of water is that everybody knows it, but no one really understands it. It’s the most fascinating substance we have come across so far, and it still has many secrets for us. For example, the molecular structure of water still eludes scientists, and as a result, water still has many properties which we […]

Recently, the University of California, Riverside provided some materials that shocked me, to say the least. According to that research, scientists from all around the world have reconstructed changes in Earth’s ancient ocean chemistry during a broad sweep of geological time, from about 2.5 to 0.5 billion years ago. What they found was that the lack of […]
