Still, science being science, we needed proof—and we got it in 1992, when two astronomers found two planets orbiting a pulsar ...

While its star projector leaves a lot to be desired, the Science Can Solar System Planetary Projector is a fantastic educational tool for kids, with its solar system model, complete with talking ...

Planets may begin forming much earlier than scientists once believed during the final stages of a star s birth, not afterward. This bold new model, backed by simulations from researchers at SwRI, ...

Astronomers have discovered the earliest seeds of rocky planets forming in the gas around a baby sun-like star, providing a precious peek into the dawn of our own solar system. It’s an unprecedented ...

Observations with the instrument SPHERE at ESO's Very Large Telescope have produced an unprecedented gallery of "debris disks ...
