When an exoplanet is discovered, scientists are quick to describe it and explain its properties. Now, we know of thousands of them, many of which are members of a planetary system, like the well-known ...

A global team of astronomers, led by the University of Warwick, have used a European Space Agency (ESA) telescope to discover a planetary system that turns our understanding of planet formation upside ...

An international team of astronomers has discovered a distant planetary system that challenges long-standing theories of how planets form. Across our galaxy, astronomers routinely observe a ...

In our Solar System, the inner planets (Mercury to Mars) are rocky, and the outer planets (Jupiter to Neptune) are gaseous. This planetary pattern – rock then gas - is consistently observed across the ...

What can rocky planets orbiting in the outer parts of a solar system teach scientists about planetary formation and evolution? This is what a recent study published in Science hopes to address as a ...

The black star represents the position of the star. The colored lines are the orbits of two planets. The yellow one is the outer, and it is highly inclined. The inner one is the red one. As time ...
