The astonishing jet of an extreme gamma-ray burst

Gamma-ray bursts (GRBs) are short duration transient phenomena lasting from a few seconds to hundreds of seconds. These bursts are localized on the sky using gamma-ray detectors onboard satellites orbiting Earth. The satellites pinpoint the direction of the burst, allowing astronomers to rapidly point their... click to read more

Long or short doesn’t matter: the tale of an unusual gamma-ray burst

Gamma-ray bursts (GRBs in short) are the most luminous known objects in the entire Universe, emitting the amount of energy that our Sun radiates in its entire life, within just a few seconds. They are created by cosmic explosions, which generate a huge amount of... click to read more

Can dark matter interact with itself?

The nature of dark matter, the invisible matter that holds galaxies together, still evades scientists almost a century after first inferring its existence. Since we cannot observe dark matter directly, like we can detect a star through the light it emits, astrophysicists study how its... click to read more

Understanding super bright mysteries of the universe

Observing a faraway astronomical object is the current best way to understand it. If we could travel to a distant star, and look at what is going on up close, the whole process of science would be a lot faster. But our best option is... click to read more
