Computer simulations suggest that high-energy radiation from baby stars is likely to create gaps in young solar systems, causing planet pile-ups in certain orbits. Image: NASA/JPL-Caltech.

Some orbits are more popular than others

In young solar systems some orbits are more popular than others. Such behaviour results in planet pile-ups and deserts.

Young galaxy cluster found

Astronomers have discovered the most distant example of a galaxy cluster.

Evolving planets constantly bombarded
