Why the idea of alien life now seems inevitable and possibly imminent

Cathal D. O'Connell, University of Melbourne This article is an edited extract from an essay, The search for ET, in The New Disruptors, the 64th edition of Griffith Review. We’re publishing it as part of our occasional series Zoom Out, where...

Origins of life: new evidence first cells could have formed at the bottom of the ocean

Sean Jordan, UCL Where did life come from? In recent years, many scientists have shifted from favouring a “primordial soup” in pools of water to hydrothermal vents deep in the ocean as the original source of life on Earth. But...

I explored the Antarctic deep seas for Blue Planet II – and it was like going back 350 million years

Jon Copley, University of Southampton “It has always been our ambition to get inside that white space, and now we are there the space can no longer be blank,” wrote the polar explorer Captain Scott, on crossing the 80th parallel...

Hidden lake discovery sheds light on alien hunt

‘Our preliminary results reveal new branches of life here,’ said Dr Gregory Farrant from Matís, a governmental research institute based in Iceland. The lake – called Skaftárkatlar – is one of the best places on earth to study how life...

Properties of Water

Dr Paul Webb Roger Williams University The most obvious feature of the oceans is that they contain water. Water is so ubiquitous that it may not seem like a very interesting substance, but it has many unique properties that impact global...

Hydrothermal Vents

Dr Paul Webb Roger Williams University A whole new ecosystem reliant on the processes of plate tectonics was discovered on the deep seafloor of the Galapagos Rift in 1977. The deep sea submersible Alvin was exploring in 2500 m of water when it...

“Over 250 stable and isolated subglacial lakes exist at and close to the ice-sheet center in Antarctica…….We show that most lakes are in a regime of hard convective turbulence, enabling efficient mixing of nutrient- and oxygen-enriched top melt-water, which is essential for biome formation…..”
