All life on Earth is based on the element carbon, but scientists aren’t sure what initially supplied all that carbon to our ...

Scientists have identified one of the largest carbon-based molecules in space yet. It could help us decode the origins of ...

太空应该存在大量碳，令人惊讶的是不太容易找到它们。最近，天文学家宣布于一片星际云发现复杂碳分子“芘 （Pyrene）”，由于该星际云类似形成太阳系的尘埃气体云，新发现可能表明此类分子是太阳系大量碳分子来源，重塑我们对宇宙碳分布与行星形成理解。

多环芳烃是由碳原子环构成的有机分子。多环芳烃在星际介质中含量丰富，天文学家认为，太空中有10%到25%的碳是由多环芳烃所储存的。因此，这些分子对于地球上的碳基生命是如何形成的理论中，占有非常重要的地位。

A team led by researchers at MIT has discovered that a distant interstellar cloud contains an abundance of pyrene, a type of ...

Exploring the lesser-known corners of the wine world, naturally. Above, Patrick Sullivan, producer of an impressive range of ...

The molecule, called pyrene, is made up of four fused planar rings of carbon. It's therefore categorized as a polycyclic aromatic hydrocarbon (PAH) — one of the most abundant complex molecules ...

The mysteries of the cosmos continue to unravel, with scientists piecing together clues about the origins of our solar system ...

A team led by researchers at MIT in the United States has discovered large molecules containing carbon in a distant ...

Complex carbon-based molecules crucial to life on Earth originated somewhere in space, but we didn't know where. Now, huge amounts of them have been spotted in a huge, cold cloud of gas ...

The European Commission has established specific maximum allowable limits for PAHs in oils: 2.0 μg/kg for benzo[a]pyrene and ...
