A smudge of light spotted by the James Webb telescope near Alpha Centauri A could be the planet with the tightest orbit ever ...

Hubble has helped uncover a white dwarf that’s likely the result of two stars crashing together. Carbon traces in its atmosphere tell a story of a cosmic merger, a rare phenomenon previously invisible ...

Alpha Centauri A, four light-years from Earth, may host a gas giant. If confirmed, no Earthlike planets orbit in the star’s habitable zone.

In some of its most ambitious work yet, the James Webb Space Telescope looked to spot a planet in a potentially habitable ...

A typical white dwarf’s core elements are obscured by thick layers of hydrogen and helium—but that covering almost entirely ...

The caldera may have blasted out its cryomagma in a single explosive event, or it may have spread its eruptions over time.

A rare planet in Nu Octantis orbits backward - hinting it may be a second-generation world formed from stellar remnants.

Astronomers have discovered the earliest seeds of rocky planets forming in the gas around a baby sun-like star, providing a precious peek into the dawn of our own solar system.

The action is unfolding in a location comparable to the asteroid belt between Mars and Jupiter containing the leftover building blocks of our solar system’s planets.
