By analyzing archival radial velocity data, astronomers have detected a new warm-Neptune alien world. The newfound exoplanet, designated HD 183579b (or TOI-1055b) is about three and a half times larger and almost 20 times ...
The vast majority of planets near foreign stars are discovered by astronomers with the help of sophisticated methods. The exoplanet does not appear in the image, but reveals itself indirectly in the spectrum. A team of scientists ...
