In the constellation Cygnus, a bright knot of stars seems to adorn one edge of a nearly perfect 20-light-year-wide circle, ...

Far above the dusty lanes of the Milky Way, an unusual structure near the star-forming hub Cygnus X is rewriting what you ...

They don’t make them like they used to — at all. It can take natural diamonds over three billion years to grow, but researchers in a South Korean lab have successfully fabricated the precious stones ...

An international team led by researchers from the University of Cologne has solved the mystery of an extraordinary phenomenon known as the "Diamond Ring" in the star-forming region Cygnus X, a huge, ...

Diamonds form deep within the Earth's mantle, around 250 kilometers below the surface, where immense pressure (up to 10 GPa) and temperatures (around 2,200 °C) compress carbon into diamonds over ...

It’s raining diamonds! Well, it’s raining diamonds on other planets at least, including some in our Solar System. And scientists recently discovered that the conditions needed to create this wild ...

Diamonds in nature famously form under immense pressure in Earth’s mantle. But a new laboratory technique allows diamonds to skip the squeeze. The most common method for producing synthetic diamonds, ...

In nature, diamonds form deep in the Earth over billions of years. This process requires environments with exceptionally high pressure and temperatures exceeding 1,000℃. Our international team has ...
