Aprovechando un eclipse lunar total, los astrónomos que utilizan el Telescopio Espacial Hubble de la NASA han detectado la marca propia de protección solar de la Tierra, el ozono, en nuestra atmósfera.
Exploración de Infrarrojos de Campo Amplio (WFIRST por sus siglas en inglés), en honor a la Dra. Nancy Grace Roman, la primera astrónomo jefe de la NASA, quien allanó el camino para los telescopios espaciales enfocados en el universo más amplio
Su tamaño y gravedad superficial son mucho mayores que los de la Tierra, y su entorno de radiación puede ser hostil, pero un planeta distante llamado K2-18b ha captado el interés de científicos de todo el mundo. Por primera vez, los investigadores han detectado signos de vapor de agua en la atmósfera de un planeta más allá de nuestro sistema solar que reside en la “zona habitable”, la región alrededor de una estrella en la que el agua líquida podría acumularse en la superficie de un planeta rocoso.
Anyone who has ever peered at Saturn through a small telescope is immediately enticed by its elegant rings, which make the far-flung planet one of the most exotic-looking, opulent worlds in the solar system.
Finding common table salt — sodium chloride — on the surface of a moon is more than just a scientific curiosity when that moon is Europa, a potential abode of life.
Astronomers once thought asteroids were boring, wayward space rocks that simply orbit around the Sun. These objects were dramatically presented only in science fiction movies.
After several years of analysis, a team of planetary scientists using NASA’s Hubble Space Telescope has at last come up with an explanation for a mysterious moon around Neptune that they discovered with Hubble in 2013.
NASA’s Hubble Space Telescope has produced this stunningly detailed portrait of the Triangulum galaxy (M33), displaying a full spiral face aglow with the light of nearly 25 million individually resolved stars. It is the largest high-resolution mosaic image of Triangulum ever assembled, composed of 54 Hubble fields of view spanning an area more than 19,000 light-years across.
This visualization of a spectacular spiral galaxy, called the Whirlpool Galaxy, appears in the “Deep Field” film. Based on a 90-megapixel image from the Hubble Space Telescope, the visualization sequence sweeps viewers past the swirling structure of dark dust lanes, yellowish older stars, bluish younger stars, and vibrant red star-forming regions.

Our solar system has eight major planets, and nearly 200 moons. Though astronomers have to date found nearly 4,000 planets orbiting other stars, no moons have yet been found. That hasn’t been for any lack of looking, it’s just that moons are smaller than planets and therefore harder to detect.
