Making stars when the universe was half its age

The Hubble Ultra Deep Field of galaxies. A new study of the star formation activity in 179 of the galaxies in this image including many dating from about six billion years ago confirms an earlier puzzling result: lower mass galaxies tend to make stars at a rate slightly slower than expected.

The universe is about 13.8 billion years old, and its stars are arguably its most momentous handiwork. Astronomers studying the intricacies of star formation across cosmic time are trying to understand whether stars and the processes that produce them were the same when the universe was younger, about half its

Audi incorporates car movement into new VR system

The holoride system could be openly available within three years

We've previously seen VR (virtual reality) platforms that move in response to what's happening onscreen, making for a more immersive experience. Audi, however, is taking the opposite approach. Its new in-car VR setup determines onscreen movements based on what the vehicle is doing in real life. First of all – yes

Salty Water Unlocks Key to Life on Mars


We are one step closer to discovering if there is life on Mars. A new after a study has suggested that there might be enough oxygen in the briny liquid that sits nears the planet's surface to support microbial life. Oxygen levels are yet to be tested, but the hypothesis allows
