NASA application grants general public the opportunity to explore the surface of Vesta

By - April 28, 2015 2 Pictures
NASA has released a browser-based application that allows citizen scientists to explore the surface of the asteroid Vesta. The 3D model was created from data harvested by the agency's Dawn spacecraft over the course of its year-long stay in orbit around the asteroid between July 2011 and September 2012. The application allows users a rare opportunity to make detailed observations of one of the lesser-known bodies in our solar system in an engaging, easy-to-use format. Read More

3D-printable AstroGro system to foster astronauts' green thumbs

By - April 27, 2015 4 Pictures
Manned missions beyond Earth orbit face the rather important problem of how to feed the crew and maintain the capsule environment for years on end without any resupply from home. The product of a NASA challenge, AstroGro is a space garden pod aimed at addressing this problem. It relies on 3D printing to produce a system that can be replicated and modified while in the depths of space. Read More

Rocks reveal secret of Moon's formation

By - April 19, 2015 2 Pictures
There are a number of ideas about where the Moon came from, but, based on orbital mechanics, the accepted theory is that about 150 million years after the Solar System formed some 4.6 billion years ago, the primordial Earth was struck by an object the size of Mars called Theia. Out of the debris of this massive impact, the Moon was formed. Scientists at the University of Maryland (UMD) have for the first time found evidence to support this theory by analyzing the isotopic “fingerprints” of rock samples brought back by the Apollo astronauts.

Hubble and VLT team up to reveal giant galaxies shutting down from the inside out

By - April 17, 2015 3 Pictures
Astronomers have used the ESO's Very Large Telescope (VLT) in conjunction with the NASA/ESA Hubble Space Telescope to reveal the secrets of how star formation shuts down in distant galaxies, just three billion years after the Big Bang. Focusing on huge, quiescent elliptical galaxies known as spheroids, the findings are expected to improve our understanding of the evolution of the Universe. Read More
