In theory, a planet may be able to orbit a binary star system in a figure of eight, but it may not be particularly stable, ...

Astronomers have captured an exceptionally rare view of young planets in mid-transformation, revealing how bloated, giant worlds may shrink into the most common planets in the galaxy. Astronomers have ...

Webb telescope discovered a bizarre exoplanet with carbon atmosphere, no hydrogen, orbiting a super-dense spinning star.

What happens when a planet defies every expectation of how worlds are supposed to form and move? In the nu Octantis system, astronomers have confirmed the existence of a planet that orbits in the ...

If you extend a line from your fingertip all the way through the Earth, that line would point in the direction of “up” to someone on a boat in the southern Indian Ocean. In the bigger picture, “down” ...

Astronomers have uncovered a rare exoplanet, HD 143811 AB b, that orbits two parent stars, mirroring the twin-sun system of Tatooine from Star Wars. This planet, however, presents an intriguing ...

Astronomers have discovered that "super-Earth" planets may exist on wider orbits than previously thought — and this implies these rocky, or "terrestrial," worlds are far more common than was suspected ...

While most planets that we are familiar with stick relatively close to their host star in a predictable orbit, some planets ...

NASA's Kepler mission has found the first multi-planet solar system orbiting a binary star, characterized in large part by University of Texas at Austin astronomers using two telescopes at the ...

Scientists measured mass and distance of free floating planet drifting through space without star for first time.

This illustration shows an exoplanet orbiting around two brown dwarfs –– objects bigger than gas-giant planets but too small to be proper stars. ESO/M. Kornmesser Astronomers have discovered a ...
