The planet’s wild orbit offers clues to how such large, hot planets take shape.

In the first quintillionth of a second, the universe may have sprouted microscopic black holes with enormous amounts of nuclear charge, MIT physicists propose.

The results offer a new way to probe supermassive black holes and their evolution across the universe.

Sunspots and flares could be a product of a shallow magnetic field, according to surprising new findings that may help scientists predict space weather.

The new world is the second-lightest planet discovered to date.

Three stars circling the Milky Way’s halo formed 12 to 13 billion years ago.

The observations suggest some of earliest “monster” black holes grew from massive cosmic seeds.

Such discoveries help researchers better understand the development of molecular complexity in space during star formation.

Analysis reveals a tiny black hole repeatedly punching through a larger black hole’s disk of gas.

The detections more than double the number of known tidal disruption events in the nearby universe.
