The Ice Queen
by Tom Chao
NASA’s Cassini spacecraft made a close pass of Saturn’s icy moon Helene on June 18, 2011. Cassini flew within 4,330 miles (6,968 kilometers) of Helene’s surface. It was the second closest approach to Helene of the mission. Cassini passed from Helene’s night side to the moon’s sunlit side. It also captured images of the Saturn-facing side of the moon in sunlight, a region that was only illuminated by sunlight reflected off Saturn the last time Cassini was close, in March 2010.

The Coldest Brown Dwarf
Explanation: This cosmic snapshot composed with image data from NASA’s Wide-field Infrared Survey Explorer (WISE) satellite captures a multitude of faint stars and distant galaxies toward the constellation Lyra at wavelengths longer than visible light. But the object circled at the center is not quite a star. Cataloged as WISE 1828+2650, it lies within 40 light-years of the Sun and is currently the coldest brown dwarf known. A brown dwarf begins like a star, with the gravitational collapse of a dense cloud of gas and dust, but is not massive enough to achieve the core temperatures and densities that trigger hydrogen fusion, the stable source of a star’s energy. Instead the failed star ultimately cools and emits most of its light at infrared wavelengths. Remarkably, brown dwarfs are roughly the size of the planet Jupiter. How cold is WISE 1828+2650? While brown dwarfshave measured surface temperatures of up to 1,400 degrees C (2,600 degress F), this brown dwarf , assigned to spectral class Y, has the estimated temperature of a warm room, less than about 27 degrees C (80 degrees F).

A list of all NASA´s current missions
It´s quite easy to get lost in the middle of the data NASA releases to the world on a daily basis. There are more than 50 missions right now under the agency´s supervision, all of them producing a myriad of amazing images and information about many different subjects such as sunspots, Earth´s atmosphere, Saturn´s moons, the birth of stars at distant galaxies and faraway asteroids.
To help us follow all that, NASA has listed all current missions on alphabetical order in a way that clicking on each one of them takes you to a specific page about the mission with all the data you need to understand all those probes, satellites, robots, telescopes and on.
