Change in definitions: A planet can orbit more than one sun and even remnants of the sun

A redefinition of planets throughout the universe is required. This is what a group of astronomers from UCLA claims * The researchers will present the new definition at the General Assembly of the International Astronomical Union in August

Scientists observed for the first time how atoms in a magnesium oxide molecule change and dissociate under extremely harsh conditions, and gained new insights into this important mineral in the Earth's mantle that is known to influence the formation of planets
An artist's impression of the large-scale landscape of FU~Ori. The image shows the currents created by the interaction between strong stellar winds triggered by the outburst and the remnant mantle from which the star formed. The stellar wind drives the shock wave into the mantle and the CO gas carried away by the shock is the new discovery of the ALMA observatory. Credit: NSF/NRAO/SDagnello

Astronomers solve the mystery of the dramatic 1936 eruption of FU Orionis

Iconography showing the habitable zone around the planet Teegarden in two conservative and optimistic scenarios, compared to our solar system and other planets discovered in their star's habitable zone. The scale is normalized to the size of our solar system. In practice the planets Teegarden b and Teegarden c are much closer to their sun. Illustration: C. Harman
