A team of astronomers has found the strongest evidence yet that some planets outside our solar system may be magnetic. Using the European Southern Observatory’s Very Large Telescope (ESO’s VLT) and the Gemini North telescope, the researchers measured wind speeds on seven very hot, Jupiter-like exoplanets.

NASA has completed its final inspection of the primary mirror on the Roman Space Telescope, which measures 2.4 meters (7.9 feet) in diameter and contains a layer of silver hundreds of times thinner than a human hair, at 400 nanometers.

4.5 billion years ago was an interesting time for Earth. The atmosphere was thick and what we would now think of as toxic. The moon, which was freshly formed, looks much more massive than it does today and faintly glows with the residual heat from its own creation. And the floor was literally lava. Everywhere. If there were any children alive at the time, they would have no chance of winning that game. But for a long time, scientists had thought this molten phase of Earth didn’t last long. But according to a new paper, available on the arXiv preprint server by researchers at the Kapteyn Astronomical Institute, it might have lasted for upward of half a billion years.

The rotation of a protoplanetary disk (a disk where planets are being formed) has been observed directly for the very first time by mapping the emissions from the dust grains within it. The disk in question surrounds the young star AB Aurigae. Although it appears to generally rotate in accordance with the laws of physics, certain regions close to the star show an unexpected departure from this behavior. A body of evidence suggests that this anomaly is caused by the presence of giant planets in the process of formation.
