Rubin Observatory Stuns and Awes With Sprawling First Look Images
Wow. Just wow.
Cinturones polvorientos ofrecen una visión más clara de la formación de exoplanetas
Las observaciones en longitudes de onda milimétricas de polvo y guijarros en 74 sistemas estelares sugieren que las migraciones planetarias podrían ser más comunes de lo que pensábamos.
A Super Speedy Star May Be Streaking Through Our Galaxy
Astronomers suggest the star is towing along an exoplanet. The system could be traveling fast enough to escape the Milky Way.
Dusty Belts Provide Clearer Insights into Exoplanet Formation
Millimeter-wavelength observations of dust and pebbles in 74 star systems hint that planetary migrations might be more common than we realized.
Earth May Survive the Sun’s Demise
A distant white dwarf hosts an Earth-like planet in an orbit that might be similar to Earth’s if it survives the Sun’s red giant phase.
ALMA Watches the Surface of a Star “Boil”
Observations of R Doradus, a nearby red giant, provide the first timescale for convection on the surface of any star other than the Sun.
Small Stars Produce Mighty UV Flares
Stronger-than-expected ultraviolet flares could either provide exoplanets the sparks of life or prevent them from having life at all.
Anemic Stars Don’t Host Super-Earths
Planetary systems need the right stuff to make planets, and some stars just don’t have it.
Las estrellas lejanas resaltan minilunas en los anillos de Saturno
Al estudiar cómo la luz de las estrellas se atenúa al viajar a través de las partículas de hielo que rodean a Saturno, investigadores han hecho foco en muchas estructuras pequeñas en los famosos anillos del gigante gaseoso.
