Astronomers have counted the number of neutrons inside carbon atoms from 2.8 quadrillion km away. The team managed to measure the ratios of carbon isotopes in the atmosphere of an exoplanet for the first time, which can tell us about how it formed.

There is a tremendously huge difference between counting something and measuring a ratio.


I wonder how many times they had to zoom and enhance the image?


Someone should tell them there are closer carbon atoms, it makes the neutrons much easier to count.


Too bad we can’t see what’s right in front of us though.


From 2.8 quadrillion km away. Just by looking at it! Science is quite a powerful tool indeed.
