The Space Age is leaving fingerprints on one of the most remote parts of the planet — the stratosphere — which has potential implications for climate, the ozone layer and the continued habitability of Earth.

Falling pieces of space junk could be altering the stratosphere and negatively impacting our climate, new research suggests.

<p>A paper in the prestigious <em>Proceedings of the National Academy of Sciences</em> today describes “a missing law of nature,” recognizing for the first time an important norm within the natural world’s workings.  </p> <p>In essence, the new law states that complex natural systems evolve to states of greater patterning, diversity, and complexity. In other words, evolution is not limited to life on Earth, it also occ...

<p>Using tools hitched to the nose cone of their research planes and sampling more than 11 miles above the planet’s surface, researchers have discovered significant amounts of metals in aerosols in the atmosphere, likely from increasingly frequent launches and returns of spacecraft and satellites. That mass of metal is changing atmospheric chemistry in ways that may impact Earth’s atmosphere and ozone layer.</p>

Atoms within the ball of iron in Earths inner core may move around more than previously thought, which could explain recent findings about the cores surprising softness.

The space age has unintentionally marked its presence on one of the most untouched realms of the Earth – the stratosphere - with metals.

MIT scientists find the sounds beneath our feet are fingerprints of rock stability. If you could sink through the Earth’s crust, you might hear, with a carefully tuned ear, a cacophany of booms and crackles along the way. The fissures, pores, and defects running through rocks are like strings that

New discoveries in Kenya may be changing long-accepted paradigms on stone toolmaking.
