An international team of researchers say they’ve found fossils dating back to at least 3.77 billion years ago, making them the oldest fossils ever found on our planet. The discovery, though sure to attract scrutiny, has implications for our understanding of how life got started on Earth—and how it may have emerged…
Marine biologists have discovered six new animal species in undersea hot springs nearly two miles deep in the southwest Indian Ocean—an area already slated for future seafloor mining.
The “scaly-foot gastropod” is a type of snail that thrives in the hydrothermal vents found deep in the Indian Ocean. And it has a unique property: a magnetic outer shell.
We’ve seen the dramatic white creatures that live around underwater vents in the Earth’s surface. But what about the vents themselves? There’s no “fire” inside them, so what is the black “smoke” pouring out of them?
Deep sea hydrothermal vents, home to exotic forms of life that exist nowhere else on earth, are very close to being commercially mined for precious and rare-earth metals. This could have profound effects on the isolated ecosystems surrounding the vents, some of which have existed for millennia.
When it comes to life on Earth, we're not sure if it came from the outside (transported by comets) or on the inside. A new theory focuses on the "interior " theory, saying that microbes could have evolved from non-living matter such as chemical compounds in minerals and gases.
There are plenty of places on Earth that seem alien to us. The deep sea is a perfect example: it's been said that we know more about Mars than we do about the bottom of the ocean.
This is a new low, even for life on Earth — geologists have found bacteria living 1.6 kilometers beneath the ocean floor, twice as deep as ever recorded before. The simple bugs (one cell pictured, at the end of the arrow) are related to the ones found at deep sea hydrothermal vents, but they represent a stunning new…
