By conducting radial velocity (RV) follow-up observations of the GJ 367 planetary system with the High Accuracy Radial velocity Planet Searcher (HARPS), an international team of astronomers has detected two additional alien ...
Depictions of the Milky Way show a coiling pattern of spiral "arms" filled with stars extending outward from the center. Similar patterns have been observed in the swirling clouds of gas and dust surrounding some young stars—planetary ...
