TESS finds three Earth-sized exoplanets orbiting binary stars
Through international collaboration, a team of astronomers has confirmed two exoplanets and found hints of a third exoplanet at a binary star system known as TOI-2267. The planets were first found by NASA’s Transiting Exoplanet Survey Satellite (TESS), using the team’s own exoplanet detection software. This tantalizing find might provide new insights into planet formation…

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…

Using data from Spitzer and TESS, scientists discover exoplanet littered with volcanoes
Using data collected by NASA’s retired Spitzer Space Telescope and NASA’s Transiting Exoplanet Survey Satellite (TESS), a team of scientists has discovered an exoplanet that could potentially be covered with volcanoes. The exoplanet is Earth-sized, and the team’s results suggest that the gravitational pull of a neighboring exoplanet could be causing an increase in volcanic…

TESS returns from safe mode, the case of the missing exoplanet atmosphere
Following an incident that triggered the telescope to enter safe mode, NASA’s Transiting Exoplanet Survey Satellite (TESS) has resumed normal science operations in its highly elliptical Earth orbit. TESS entered safe mode on Monday, Oct. 10, and was in the protective states until Thursday, Oct. 13, at approximately 22:30 UTC. Meanwhile, a team of researchers…

Three years on, TESS delivers on discoveries as extended mission continues
Three years ago, on April 18, 2018, NASA’s and the Massachusetts Institute of Technology’s Transiting Exoplanet Survey Satellite, or TESS, launched successfully into a very high Earth orbit aboard the last new Block 4 Falcon 9 before the current human-rated Block 5 entered service. Since then, it has dutifully observed the southern and northern skies,…

TESS reveals triple-binary eclipsing star system & Sun-like star with extremely close exoplanets
The first-discovered triple-binary sextuple star system and a Sun-like star with five exoplanets orbiting within the distance of Mercury are just two recent examples of the extraordinary systems being investigated and discovered by scientist using data from the Transiting Exoplanet Survey Satellite, or TESS. The joint NASA-Massachusetts Institute of Technology (MIT) mission is the cornerstone…

From supernova to something much more intriguing at the core of galaxy 253-3
On 14 November 2014, a bright flash flagged the All Sky Automated Survey for Supernovae, or ASAS-SN — a global network of 20 telescopes managed at Ohio State University in the U.S. The flash originated in galaxy ESO 253-3, located 570 million light-years away. The sudden burst of energy was examined by astronomers and categorized…

First possible “survivor” planet orbiting a white dwarf seen via NASA telescopes
A potential planet… where no planet should be. An international team of astronomers utilizing NASA’s Transiting Exoplanet Survey Satellite and data obtained from the now-retired Spitzer space telescope have reported an astounding potential discovery of a surviving planet closely orbiting a white dwarf. So what’s the big deal? Scientists have found many exoplanets in close…
