CHEOPS discovers exoplanet triggering explosive flares on host star
Using the European Space Agency’s Characterizing Exoplanets Satellite (CHEOPS) telescope, a team of astronomers has discovered an exoplanet that may be triggering its host star to release massive flares of radiation. These flares are similar to the coronal mass ejection our Sun produces, and the harsh radiation emitted from the flares is slowly blowing away…

Webb identifies surprising carbon-rich ingredients around young star
Using the joint NASA, European Space Agency (ESA), and Canadian Space Agency (CSA) James Webb Space Telescope, a team of international scientists studied a disk of cosmic material surrounding an extremely low-mass star. The results from the investigation show the richest hydrocarbon chemistry ever observed within a protoplanetary disk, which is a disk of gas,…

Webb detects neon in young star system, provides insight into planet formation
In 2008, observations from NASA’s now-retired Spitzer infrared space telescope hinted at the presence of neon within the protoplanetary disk of Sun-like star SZ Chamaeleontis (SZ Cha). However, Spitzer’s instruments could not confirm whether this reading was correct. Over a decade after Spitzer’s results were published, the joint NASA, European Space Agency, and Canadian Space…

Using new data analysis tool on Swift, scientists discover black hole snacking on a star
Scientists, using NASA’s Neil Gehrels Swift Observatory, have discovered a black hole that is continuously snacking on a star that is similar to our Sun. Located in a galaxy around 500 million light-years away from Earth, the black hole’s constant nibbling on the star, a phenomenon known as a tidal disruption event, creates a bright…
