A young star called V1298 Tau is giving astronomers a front-row seat to the birth of the galaxy’s most common planets. Four ...

Four planets orbiting a newly born star in our galaxy are so light that they have the density of polystyrene, and could provide a key missing link in helping us understand how the most common ...

V1298 Tau links swollen young worlds to the compact planets that astronomers keep finding, and its timing signals made that connection measurable. Future transit-timing and atmospheric observations ...
