Gamma-ray bursts (GRBs) are extremely energetic events occurring in distant galaxies which represent the brightest and most powerful class of explosion in the Universe. These extreme electromagnetic emissions are second only to the Big Bang as the most energetic and luminous phenomena known. Gamma-ray bursts can last from a few milliseconds to several hours. After the initial flash of gamma rays, a longer-lived afterglow is emitted, usually in the longer wavelengths of X-ray, ultraviolet, optical, infrared, microwave or radio frequencies.

There are explosions in the universe so powerful that, for a few seconds, they outshine entire galaxies. They are called Gamma-Ray Bursts (GRBs). They arrive without warning, from random directions in the sky, releasing in seconds as much energy as the Sun will emit over its entire lifetime. For decades,Continue Reading

In the distant universe, there are objects so bright that they outshine entire galaxies. They are called quasars, short for quasi-stellar radio sources, and they are among the most powerful phenomena known to astronomy. A single quasar can emit more light than a trillion stars. To observers on Earth, theyContinue Reading

The Dark Forest Theory is a solution to the Fermi Paradox which highlights the contradiction between the high probability of extraterrestrial civilizations existing and the lack of contact with such civilizations. The Dark Forest Theory is a compelling hypothesis that offers a unique perspective on why we haven’t encountered extraterrestrial civilizations.Continue Reading
