When the universe was about 3 billion years old, just 20% of its current age, it experienced the most prolific period of star birth in its history. But when astronomers gazed toward cosmic objects in this period, they found something odd: six early, massive, 'dead' galaxies that had run out of the cold hydrogen gas needed to make stars.

Star-forming galaxies are responsible for creating gamma-rays that until now had not been associated with a known origin. Gamma rays are one of the most energetic forms of light in the universe, and Aussie researchers say they have been able to pinpoint how they form.

Transporting a single brick to Mars can cost more than a million dollars - making the future construction of a Martian colony seem prohibitively expensive. Scientists have now developed a way to potentially overcome this problem, by creating a concrete-like material made of extra-terrestrial dust along with the blood, sweat and tears of astronauts.
