Across the Milky Way and beyond, planetary systems appear to fall into a few recurring blueprints, and recent exoplanet surveys suggest that just four layouts may dominate the universe. Drawing on ...
In a surprising twist to our understanding of exoplanetary systems, astronomers have uncovered three Earth-sized planets orbiting a binary star system known as TOI-2267. This rare configuration, ...
Astronomers poring over four years of data from NASA’s Kepler spacecraft have discovered a star that’s 11.2 billion years old and has at least five Earth-size planets. “We thus show that Earth-size ...
A young star called V1298 Tau is giving astronomers a front-row seat to the birth of the galaxy’s most common planets. Four ...
Scientists on Earth use seismometers to get a more detailed picture of what the inside of the Earth is made of. Those seismometers record vibrations from earthquakes. The vibrations change depending ...
A giant planet the size of Saturn orbiting a sun-like star has potentially been identified in our nearest neighbouring stellar system, Alpha Centauri. At just four light years from Earth, Alpha ...
New work from a team of Carnegie scientists (and one Carnegie alumnus) asked whether any gas giant planets could potentially orbit TRAPPIST-1 at distances greater than that of the star’s seven known ...
A new study has proposed the existence of Planet Y, an alternative Planet Nine candidate that is smaller and closer to Earth than the hypothetical Planet X, which astronomers have been hunting for ...
