General relativity, optics, the concept of time, all come together in this celestial object’s story, the end of which has been written, but has not yet passed
Next time we drink a glass of water, we should consider that our life may be more related to the stars than we think, and that in addition to stardust we are the result of a clash of giants
Things don’t always seem smaller the farther away you get. It’s a strange phenomenon of astrophysics that doesn’t correspond to our everyday experience
The concept of time is key to understanding perception, but it is not as simple or easy to understand as we would like
More than two decades ago, the Hubble Space Telescope began to show us the fate of the stars, galaxies and, by extension, the cosmos, which is in irreversible decline
