In order to explain the presence of these heavier elements today, it’s necessary to find phenomena that can produce them. One type of event that fits the bill is a gamma-ray burst (GRB) – the most powerful class of explosion in the universe.

Meteoroids are difficult objects for aerospace and geophysics researchers like us to study, because we can’t usually predict when and where they will hit the atmosphere. But on very rare occasions, we can study artificial objects that enter the atmosphere much like a meteoroid would.

A young star that astronomers have studied for decades has been found to be part of a duo, encircled by a disk of material within which planets may have just begun coalescing.

A low-mass star races through the Milky Way at over a million miles per hour, a journey that began with either the supernova explosion of a vampire star or an encounter with black holes.

The two black holes at the heart of the galaxy OJ 287 are true behemoths with masses of 18.35 billion and 150 million times the mass of our Sun.
