Nearly one third of known exoplanets are enormous gas giants, similar to Jupiter or Saturn. But whereas our Solar System developed with gas giants far from our Sun, some planetary systems consist of so-called ‘hot — or even ultra-hot — Jupiters’ orbiting very close to their star, some as close as Mercury is to the Sun. These hot, puffy giants endure extreme temperatures and are sometimes nicknamed ‘roasting marshmallows’.

Casi un tercio de los exoplanetas conocidos son enormes planetas gigantes gaseosos, similares a Júpiter o Saturno. Si bien nuestro Sistema Solar se desarrolló con gigantes gaseosos alejados del Sol, otros sistemas planetarios están formados por exoplanetas conocidos como “Júpiter calientes” o incluso “ultracalientes”, que orbitan muy cerca de su estrella, algunos tan cerca como Mercurio de nuestro Sol.

are the faintest type of galaxy in the Universe. Typically containing just a few hundred to a thousand stars — compared with the hundreds of billions that make up the Milky Way — these small diffuse structures usually hide inconspicuously among the many brighter residents of the sky. For this reason, astronomers have previously had the most luck finding them nearby, in the vicinity of our own Milky Way Galaxy.

Las  corresponden al tipo de galaxias más tenues del Universo. Se trata de pequeñas estructuras débiles que suelen contener entre unos cientos hasta miles de estrellas —en comparación con los cientos de miles de millones de estrellas que componen la Vía Láctea, por ejemplo—, y que por lo general se esconden discretamente entre los innumerables objetos brillantes del cielo. Por esta razón, hasta el momento es más fácil encontrarlas cerca de nosotros, en las proximidades de la Vía Láctea.

Previous Next BYLINE: NSF NOIRLab Newswise — Galaxy clusters are some of the largest known structures in the known Universe. Current models suggest that these massive structures form as clumps of dark matter and the galaxies that form within them are pulled together by gravity to form groups of dozens of galaxies, which in turn merge to form clusters of hundreds, even thousands. One such group is the Antlia Cluster (Abell S636), located around 130 million light-years from Earth in the...
