Our universe is not stable according to the currently measured values of the top quark and Higgs particle masses. There is a non-null probability that at any instant in the next billions of years the present “false vacuum” will […]

Superconductors are a particularly strange kind of metal. What makes them different is their behavior at very low temperatures – extremely low, that is, close to absolute zero. Basic thermodynamics dictates that in this regime we should expect all motion […]

Author:. Miguel Santander-García holds a PhD in astrophysics (Universidad de La Laguna). After several years working as a support astronomer for the Isaac Newton Group of Telescopes in La Palma, he is currently a postdoctorate fellow at the Observatorio Astronómico […]

Let’s start with a thought experiment. We are looking up to a starry night sky. What if we turn off every star in our Galaxy? The heavens would become much darker, but some light sources would still be working. […]

A couple of weeks ago I had the chance of having a fulfilling chat with Riccardo Cerulli, one of DAMA main researchers. They are at the very center of a skepticism tornado about their results on Dark Matter direct detection, […]

Black holes are not only gravitationally attractive: they also capture people’s attention. Just mention these two words in a course of elementary astronomy or in a public conference and you will find most eyes wide open. Even though they are […]

Supernovae are one of the most fascinating events in stellar astrophysics. Most stars suffer explosions at some point of their last days but the most massive ones explode releasing incredible amounts of energy and rivaling in brightness with the rest […]

Last month, a lot of newspapers and websites have been promoting this article on Nature referring to a recent preprint uploaded by Stephen W. Hawking to the internet repository ArXiv. In this work, summarizing what he talked about in […]

Time scales for astrophysical phenomena are sometimes thought to be overwhelmingly large and to exceed by far human life. While this is true for many cases, there are others which take the blink of an eye. Halfway between them, some […]

Much attention has been payed lately to the novice comet C/2012 S1, more widely known as comet ISON. At the crest of the wave, it was even said that the integrated brightness of the comet after the perihelion could exceed […]
