Two sub-Neptune exoplanets detected by astronomers

Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered two sub-Neptune exoplanets orbiting a subgiant star known as TOI-6054. The newfound alien worlds are nearly three times larger than the Earth. The finding was reported in a paper published Jan. 15 on the pre-print server arXiv.
