NASA's Solar Dynamics Observatory catches sight of an extremely long filament of solar material in the form of a long, dark tendril across the sun's surface.

This planetary nebula, Mz3, is being cast off by a star similar to our Sun.  The 1000-kilometer per second speed of the expelled gas, the light-year long length of the structure, and the magnetism of the star visible at the nebula's center, all imply  Mz3 is hiding a second, dimmer star that orbits close in to the bright star. A competing hypothesis holds that the central star's own spin and magnetic field are channeling the gas. (ESA, NASA's Hubble, JPL-CalTech)

Only 15 minutes after its closest approach to Pluto on July 14, 2015, NASA’s New Horizons spacecraft looked back toward the sun and captured this near-sunset view of the rugged, icy mountains and flat ice plains extending to Pluto’s horizon. The smooth expanse of the informally named icy plain Sputnik Planum (right) is flanked on the left by rugged mountains up to 11,000 feet (3,500 meters) high, including the informally named Norgay Montes in the foreground and Hillary Montes on the…

La presencia de partículas neutras o sin carga en regiones más frías del Sol facilita la movilidad de los campos magnéticos, permitiendo que los chorros de plasma (espículas) se emitan hacia el espacio.

Saturn eclipsing the sun, with the Earth visible in the upper left section of Saturn's rings. In 2009, NASA's robotic Cassini spacecraft drifted in Saturn's shadow for about 12 hours and Cassini saw a view unlike any other.  The rings light up so much that new rings were discovered. (NASA/APOD)

Kepler-186f ~ The first known Earth-size planet to lie within the habitable zone of a star beyond the Sun. Discovered using data from the prolific planet-hunting Kepler spacecraft, the distant world orbits its parent star, a cool, dim, M dwarf star about half the size and mass of the Sun, some 500 light-years away from us, in the constellation Cygnus. While the size and orbit of Kepler-186f are known, its mass and composition are not, and can't be determined by Kepler's transit technique…
