By analyzing the data from the TESS-Keck Survey (TKS), an international team of astronomers reports the detection of two almost identically sized sub-Neptune exoplanets orbiting a nearby star. The newly found alien worlds, ...
How will the solar system die? It's a hugely important question that researchers have considered deeply, using our knowledge of physics to create complex theoretical models. We know that the sun will eventually become a "white ...

Using NASA's Transiting Exoplanet Survey Satellite (TESS), astronomers have discovered a new inflated, low-density "hot Jupiter" exoplanet. The newly found alien world, designated TIC 257060897b, is about 50 percent larger ...
Considered an ultra-hot Jupiter—a place where iron gets vaporized, condenses on the night side and then falls from the sky like rain—the fiery, inferno-like WASP-76b exoplanet may be even more sizzling than scientists ...

An international team of astronomers has detected a new ultra-hot Jupiter extrasolar planet using NASA's Transiting Exoplanet Survey Satellite (TESS). The newfound alien world is nearly two times larger than Jupiter and has ...
Superflares, extreme radiation bursts from stars, have been suspected of causing lasting damage to the atmospheres and thus habitability of exoplanets. A newly published study found evidence that they only pose a limited ...
