An astrophysicist and a molecular and cell biology expert discuss what we know, what we don’t, and how we’re trying to find out more about how life arose on Earth and whether it might exist elsewhere.
From life on Earth to the planet itself, there are four ways our planet will actually experience “the end,” no matter how we define it.
Hints of a previously unknown, primordial form of the substance could explain why the cosmos now seems to be expanding faster than theory predicts.
It’s one of the most remarkable achievements of science of all: that we can go back billions of years in time and understand when and how our Universe, as we know it, came to be this way.
Two studies move us closer to understanding the origins of life on our planet. They may also help with another of the great mysteries of science - helping us to understand where to look for life on other planets.
Two ways to measure the age of the universe give different answers. The discrepancy is large enough that some cosmologists — scientists studying the history and makeup of the universe as a whole — are suggesting the field is in crisis.
At the center of a distant galaxy there's a black hole with the mass of several billion suns. And now, for the first time, we can see it.
