UChicago scientists have discovered evidence in a meteorite that a rare element, curium, was present during the formation of the solar system. The finding ends a 35-year-old debate on its possible pre...
Infant planetary systems are usually nothing more than swirling disks of gas and dust. Over the course of a few million years, this gas gets sucked into the center of the disk to build a star, while t...
Scientists at the University of Arizona have discovered what might be the closest thing to "baby photos" of our solar system. A young star called HD 95086 is found to have two dust belts, analogous to...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have observed what may be the first-ever signs of windy weather around a T Tauri star, an infant analog of our own Sun. This m...

The geology of the Moon and the dynamics of the early solar system are much clearer now thanks to three new studies of the lunar surface by NASA's Lunar Reconnaissance Orbiter (LRO). As well as provid...
The solar system is up two million years older than previously thought, according to a pair of researchers in the US. Their work, which is based on dating a meteorite found nestled in the Sahara deser...
Lead-lead (Pb-Pb) dating is among the most widely used radiometric dating techniques to determine the age of really old things, such as the age of the Earth or the Solar System. However, recent advanc...
