Analyzing a sample of 300 of the best-characterized planetary systems among the more than 1,000 known in the Milky Way, an ...

Scientists have performed a cosmic genealogy on planetary systems in the Milky Way, finding two distinct families that ...

In our solar system, the inner planets (Mercury to Mars) are rocky, and the outer planets (Jupiter to Neptune) are gaseous. This pattern – rock to gas – has been consistently observed across the Milky ...

Using ALMA’s exceptionally sharp vision, astronomers have uncovered rings, gaps, and cavities in extremely compact disks ...

JWST has revealed that young planetary systems lose their planet-building gas through a changing mix of powerful jets, molecular winds, and radiation-driven outflows. As the disks age and their gas ...

We present a comprehensive openly accessible repository of Judd-Ofelt (JO) spectroscopic parameters for rare-earth-doped materials, derived from a systematic compilation of data sourced from ...

Earth and Mars emerged from the same young solar system around 4.5 billion years ago, yet they may have been assembled ...

We're starting to see just how exceptional our own solar system and its history is, as more exoplanets are discovered. A fourth exoplanet discovery in the LHS 1903 system made by ESA's CHEOPS mission ...

Add Yahoo as a preferred source to see more of our stories on Google. An artist's impression of a planetary system with four planets, around a small red star, called LHS1903 with a large reddish-brown ...

The Planetary Systems and Star Formation (PSF) Panel will identify and articulate the scientific themes that will define the frontier in PSF research in the 2010-2020 decade. This panel will consider ...
