Reconstructed ancient ocean reveals secrets about the origin of life

Researchers from the University of Cambridge have published details about how the first organisms on Earth could have become metabolically active. The results, which are reported in the journal Molecular Systems Biology, permit scientists to speculate how primitive cells learned to synthesize their organic components – the molecules that form RNA, lipids and amino acids. The findings also suggest an order for the sequence of events that led to the origin of life.

Scientists successfully use krypton to accurately date ancient Antarctic ice

A team of scientists has successfully identified the age of 120,000-year-old Antarctic ice using radiometric krypton dating – a new technique that may allow them to locate and date ice that is more than a million years old.

Ancient volcanic explosions shed light on Mercury’s origins

The surface of Mercury crackled with volcanic explosions for extended periods of the planet’s history, according to a new analysis led by researchers at Brown University. The findings are surprising considering Mercury wasn’t supposed to have explosive volcanism in the first place, and they could have implications for understanding how Mercury formed.

An ancient 'Great Leap Forward' for life in the open ocean

It has long been believed that the appearance of complex multicellular life towards the end of the Precambrian (the geologic interval lasting up until 541 million years ago) was facilitated by an increase in oxygen, as revealed in the geological record.

Report: Ancient fresh water lake on Mars could have sustained life

Scientists have found evidence that there was once an ancient lake on Mars that may have been able to support life, in research published today in the journal Science.

Mars crater may actually be ancient supervolcano

Scientists from NASA and the Planetary Science Institute in Tucson, Ariz., have identified what could be a supervolcano on Mars—the first discovery of its kind. The volcano in question, a vast circular basin on the face of the Red Planet, previously had been classified as an impact crater.

Ancient snowfall likely carved Martian valleys

Valley networks branching across the Martian surface leave little doubt that water once flowed on the Red Planet. But where that ancient water came from — whether it bubbled up from underground or fell as rain or snow — is still debated by scientists.

Ancient trapped water may explain Earth's first ice age

Tiny bubbles of water found in quartz grains in Australia may hold the key to understanding what caused the Earth's first ice age.

Ancient Egyptians accessorized with meteorites

Researchers at The Open University (OU) and The University of Manchester have found conclusive proof that Ancient Egyptians used meteorites to make symbolic accessories.

The hot blue stars of NGC 2547

The Universe is a considerably old neighbourhood, weighing in at approximately 13.8 billion years old. Our galaxy, the Milky Way, is also ancient - as some of its stars are more than 13 billion years old.

Ancient impact crater found in Greenland



An international team of scientists has identified an ancient 100 kilometer-wide crater near the Maniitsoq region of West Greenland.

Ancient galaxy seen creating two stars a week

Astronomers using NASA's Spitzer and Hubble space telescopes have discovered that one of the most distant galaxies known is churning out stars at the rate of 100 per year.

Third type of ancient human interbred with our ancestors

Researchers have discovered that a recently-discovered type of ancient human interbred with our ancestors.

Door to the Afterlife creaks open in Egypt

Archaeologists have managed to painstakingly unearth a 3,500-year-old "Door to the Afterlife" that was originally placed in the tomb of an ancient high-ranking Egyptian official in Luxor.
