Jupiter's unknown journey revealed
The giant planet Jupiter was formed four times further from the sun than its current orbit, and migrated inwards in the solar system over a period of 700000 years. Researchers found proof of this incredible journey thanks to a group of asteroids close to Jupiter.

Giant X-ray 'chimneys' are exhaust vents for vast energies produced at Milky Way's center
At the center of our galaxy, where an enormous black hole blasts out energy as it chows down on interstellar detritus while neighboring stars burst to life and explode. astronomers have discovered two exhaust channels -- dubbed the 'galactic center chimneys' -- that appear to funnel matter and energy away from the cosmic fireworks.

Neural networks predict planet mass
To find out how planets form astrophysicists run complicated and time consuming computer calculations. Scientists have now developed a totally novel approach to speed up this process dramatically. They use deep learning based on artificial neural networks, a method that is well known in image recognition.
