The Nirba, an alien predator The Nirba is is slightly larger than the Lashlarm. It lives in the water, near the edge, much like a crocodile or alligator but is not fully aquatic. The Nirba comes out to prey on other animals that come down to the water, particularly the Lashlarm....
Origins asks one question: how did the Earth make us? More accurately, like a six-year-old whose curiosity cannot be sated, there lies a series of recursive “why” questions at the heart of this book. Astrobiologist and science communicator Lewis Dartnell takes a big history look at human...
"We have been ignorant about the things that we have been doing to the Earth's biosphere and it is much more complex and amazingly interdependent than anything we're likely to see in this solar system." Can we build a biosphere? The new editorial calls for meeting the goals that ...
Though a new Boeing 747-8, for example, costs around $350 million, fuel and operations are much less expensive by comparison. Once a passenger flight lands, the plane can be rapidly prepared for its next trip and it can make thousands of flights over its lifetime. The DC-X rocket ...
Phosphorus should also exist in a form called schreibersite, which is a mineral containing nickel, iron and phosphorus, he says. "We find it in meteorites all the time, and in the more cometary forms. It does imply that pretty much all the meteorites we collect, which have a small amoun...
When an asteroid plows into the Earth, it destroys pretty much everything in its path. But new research has shown that glass created during a searing asteroid impact can actually trap microscopic signs of life for millions of years, providing scientists
However intriguing this is, it may be too good to be true. “I’m dubious as to how common dark-matter-heated planets really are,” says astrobiologist Lewis Dartnell of University College London. “Although their model is consistent with some theories of the nature and distribution of dark ...

Earth is one of the inner planets of the Solar System, but – unlike the others – it has an oxidising atmosphere, relatively stable temperature,
Milankovitch cycles are periodic changes in the orbital characteristics of a planet that control how much sunlight it receives thus affecting its climate and habitability.
