Hubble Gets a Celestial Boost 

The NASA/ESA Hubble Space Telescope doesn’t usually get much assistance from its celestial subjects — but to take this image, the telescope opted for teamwork and made good use of a fascinating cosmic phenomenon known as gravitational lensing.
This effect works when the gravitational influence of a massive object, such as the galaxy cluster in this image, is so colossal that it warps the surrounding space, causing nearby light to travel along distorted paths. The massive object is effectively turned into a giant magnifying glass, bending and amplifying the light traveling from more distant galaxies lying behind it.
In this particular case, astronomers used the foreground galaxy cluster (named SDSS J0915+3826) to study star formation in galaxies lying so far away that their light has taken up to 11.5 billion years to reach Earth. These galaxies formed at a very early stage in the lifetime of the universe, giving astronomers a rare glimpse into the beginning of the cosmos. Despite the distance of these galaxies, the lensing effects of SDSS J0915+3826 allowed astronomers to work out the sizes, luminosities, star formation rates and stellar populations of individual star-forming clumps within these galaxies — quite an achievement!

Small Satellites yield Big Discoveries
Remember the old adage: Big things come in small packages? NASA has updated it - in the form of CubeSats. Imagine a real, working satellite that’s so small you can hold it in your hands: Just 4 inches (10 cm) across, these cubes can be expanded incrementally depending on their specific mission objectives. The technology packed into these tiny denizens of space is impressive. Originally developed in 1999 by Cal Poly San Luis Obispo and Stanford University for educational purposes, NASA has since used them for new science missions and to test new electronics, sensors and software that might be included on larger missions.

Astronomers have discovered the Milky Way's disk is warped and twisted, not flat like a pancake. The researchers hypothesize that as the Milky Way’s inner disk of stars rotates, it drags on the outer disk as well, distorting the flat spiral http://ow.ly/YqzJ30nA87o

They'll never stop learning.

Its interesting isn't it that they are still learning things from the Apollo moon rocks 50 years later.

That was on our news too.

NASA Research Could Reshape Understanding of Moon Formation

New NASA research combining experimental studies with analyses of samples collected nearly 50 years ago during Apollo provides compelling evidence that the Moon formed from the same materials as Earth in the aftermath of a giant impact between the young Earth and a Mars-sized impactor.
