We’ve found an exo-planet with an extraordinarily eccentric orbit

A solitary planet in an eccentric orbit around an ancient star may help astronomers understand exactly how such planetary systems are formed.
It’s a bird… It’s a plane… No, it’s an object from another solar system! Astronomers have been scrambling to identify a mysterious object passing through our solar system at a speed of about 160,000 km/h. This NASA file image shows a simulation of asteroids passing the earth. (Handout)

How scientists discovered our first interstellar mystery visitor

Astronomers have detected what is believed to be the first interstellar object ever seen passing through our solar system.

The beauty and mystery of Saturn’s rings revealed by the Cassini mission

The Cassini space probe took us up close and through the beautiful rings of Saturn. It captured some amazing images, and even the sound of the rings during its mission.

The PLATO mission: an investigation of planetary systems

While we on Earth are familiar with our own star, the Sun, the European Space Agency's PLATO mission will explore solar systems similar to ours as well as those that are more exotic.

Six mysteries of Jupiter’s Great Red Spot

Juno has flown closer to the solar system's most famous storm than any other spacecraft to take the most detailed images to date. They may help scientists reveal some of the spot's best-kept secrets.
