Using the radial velocity method, an international team of astronomers has discovered a new extrasolar planet orbiting a nearby star known as GI 410. The newfound alien world was classified as a sub-Neptune exoplanet with a mass of at least 8.4 Earth masses. The discovery was reported April 4 on the pre-print server arXiv.

Using the James Webb Space Telescope (JWST), an international team of astronomers has observed a planetary nebula designated Messier 57 (also known as NGC 6720), dubbed the Ring Nebula. As a result, they found that the central star of this nebula is surrounded by a dusty ring. The finding was detailed in a paper published April 1 on the arXiv preprint server.

Using the 10.4-m Gran Telescopio Canarias (GTC), European astronomers have detected methane in the atmosphere of WISEA J181006.18−101000.5—the closest T dwarf to Earth. The finding was reported in a research paper published March 28 on the arXiv pre-print server. Brown dwarfs are intermediate objects between planets and stars.
