ANIMATION New research shows that sunspots and other active regions can change the overall solar emissions. The sunspots cause some emissions to dim and others to brighten; the timing of the changes also varies between different types of emissions. This knowledge will help astronomers characterize the conditions of stars, which […]

A hot planet transits in front of its parent star in this artist impression of an exoplanet system.

Ariel, the Atmospheric […]

This illustration depicts Kepler-186f, the first validated Earth-size planet to orbit a distant star in the habitable zone. Credit: NASA Ames/JPL-Caltech/T. Pyle Since astronomers confirmed the presence of planets beyond our solar system, called exoplanets, humanity has wondered how many could harbor life. Now, we’re one step closer to finding an […]

This new image of C/2014 OG392 (PANSTARRS) and its extensive coma combines many digital images into a single 7,700 second exposure. The dashed lines are star trails caused by the long exposure. Images captured October 14, 2020 using the Large Monolithic Imager on the 4.3 m Lowell Discovery Telescope. Credit: […]

The Ultra Hot Neptune. Credit: Ricardo Ramirez International team including University of Warwick astronomers discovers a new class of planet, the Ultra Hot Neptune The planet was found in the Neptunian Desert, where such objects are rarely found Could be a transitional planet, a deflated gas giant Provides a unique opportunity to study […]

This artist’s impression shows LTT 9779b near the star it orbits and highlights the planet’s ultra-hot (2000 Kelvin) day-side and its quite toasty night-side (around 1000 K). Credit: Ethen Schmidt A team led by an astronomer from the University of Kansas has crunched data from NASA’s TESS and Spitzer space telescopes to portray […]

Artist’s impression of the multi-planetary system orbiting a red dwarf star. Credit: Mark Garlick The “SAINT-EX” Observatory, led by scientists from the National Centre of Competence in Research NCCR PlanetS of the University of Bern and the University of Geneva, has detected two exoplanets orbiting the star TOI-1266. The Mexico-based telescope thus […]

Cheops is ESA’s CHaracterising ExOPlanet Satellite. It is the first mission dedicated to studying bright, nearby stars that are already known to host exoplanets, in order to make high-precision observations of the planet’s size as it passes in front of its host star. Credit: ESA ESA’s new exoplanet mission, Cheops, has found a […]
