Scientists have documented a tenfold surge of lithium atoms in the upper atmosphere and have traced it directly to the uncontrolled re-entry of a Falcon 9 rocket stage.
The finding establishes that burning space hardware can leave a measurable…
Scientists have many theories about how Earth’s raw materials turned into living cells, but a new proposal is particularly slimy.
In a recent paper, an international team argues that life may have first emerged within a blob of sticky goo…
The Moon is a quarter of the way back to us now, meaning there is more than enough of its surface lit up that we can enjoy some Moon gazing. So, what can you see when you look up…
China’s armed forces are openly seeking artificial intelligence tools to track undersea targets, analyse satellite orbits, generate deepfakes and fuse battlefield data at speed, according to a sweeping new study of more than 9,000 procurement…
For decades, scientists have been studying intriguing “gravity holes,” which are enormous depressions in the Earth’s crust where the effects of gravity are significantly lower than average.
It’s an especially pertinent phenomenon…
For years, scientists have debated how the Kuiper Belt’s “snowman” worlds formed. Did two separate bodies collide at just the right speed to stick together – or were they born as pairs from the start?
A new computer simulation now tips the…
A chemical reaction on the ocean floor has emerged as the decisive factor that allowed one planet-wide ice age to last 56 million years while a later freeze ended after just 4 million years.
That result overturns the long-standing assumption that…
When killer whales attacked a great white shark near South Australia’s Neptune Islands in 2015, the story spread quickly.
After the attack, white sharks disappeared from the area for 69 days. Many people blamed fear of orcas for driving them…
