Zeroing in on baby exoplanets could reveal how they form

Twenty-four years ago, Swiss astronomers Michel Mayor and Didier Queloz discovered the first planet orbiting a sun-like star outside our solar system—a milestone recognised by this year's Nobel prize in physics. Today we ...

For newborn planets, solar systems are naturally baby-proof

Numerical simulations by a group of astronomers, led by Mario Flock from the Max Planck Institute for Astronomy, have shown that young planetary systems are naturally "baby-proof": Physical mechanisms combine to keep young ...

New space discovery sheds light on how planets form

Researchers at Dartmouth College have discovered a planet orbiting one of the brightest young stars known, according to a study published in the journal The Astrophysical Journal Letters. Aged at approximately 45 million ...

Rapid destruction of Earth-like atmospheres by young stars

The discoveries of thousands of planets orbiting stars outside our solar system has made questions about the potential for life to form on these planets fundamentally important in modern science. Fundamentally important for ...

Exiled planet linked to stellar flyby three million years ago

Some of the peculiar aspects of our solar system—an enveloping cloud of comets, dwarf planets in weird orbits and, if it truly exists, a possible Planet Nine far from the sun—have been linked to the close approach of ...

Unknown treasure trove of planets found hiding in dust

"Super-Earths" and Neptune-sized planets could be forming around young stars in much greater numbers than scientists thought, new research by an international team of astronomers suggests.
