Some exoplanets in their stars' habitable zones may be distinctly uninhabitable due to solar flaring. Red dwarfs are known for powerful flaring, and since they're dim and their habitable zones are ...

Sedna will make its closest approach to the Sun in 2076, giving us a rare opportunity to visit the planetoid before it drifts ...

A team of international researchers led by Tomas Stolker in the Netherlands has imaged a young gas giant exoplanet near a 12-million-year-old star. The planet is orbiting a star whose planet formation ...

There are 8 planets in our solar system. The planets orbit the Sun in elliptical trajectories, and they are all different in size, composition, temperature, and characteristics.

A close-in exoplanet is triggering stellar flares and self-destructing. This is the first direct evidence of planet-star ...

Stars passing close to the sun could cause planets to collide, including with Earth, or even be ejected as rogue planets, new simulations show.

Centimeter-sized pebbles have been detected in protoplanetary discs using e‑MERLIN, filling in a critical phase of planet ...
