Space pics. Fotos espaciales.

Encuentro en http://news.nationalgeographic.com nuevas fotos espaciales tomadas esta misma semana desde el NASA/ESA Hubble Space Telescope entre otras fuentes


Enjoy!


Confetti colors adorn the dwarf galaxy NGC 4214 in a composite picture from theNASA/ESA Hubble Space Telescope released Thursday.

 
The galaxy, about ten million light-years from Earth, is roiling with star formation. But astronomers have also seen clusters of much older stars dotted around this "starburst" galaxy, indicating that the current round of star births is not the first to happen in this part of space.
And the galaxy's abundant hydrogen—the main ingredient in stars—means that star birth in the region will likely continue far into the future.





Deep fractures cut across the surface of the red planet in a recently released picture from the European Space Agency's Mars Express orbiter.
The image captures part of the Nili Fossae region, a collection of curved faults and troughs northwest of the ancient impact basin Isidis. The curves tend to follow the outline of the basin, suggesting the fractures formed in the aftermath of the impact.





NASA's Solar Dynamics Observatory recently zoomed in on an active region of the sun, capturing this image of plasma—charged gas—streaming back and forth along magnetic field lines.
SDO watched as the suspended plasma, glowing red hot in extreme ultraviolet light, shuttled above the sun's surface for more than two days.




Molecular winds flow from a galaxy in an artist's rendering. With its powerful infrared vision, the European Space Agency's Herschel space telescope has detected raging winds of molecular gas streaming away from galaxies—with the fastest gales reaching 621 miles (1,000 kilometers) a second.
