Astronauts Make First Cement in Space to Support Future Martian Habitats
Concrete made in space could one day help humans build habitats on the moon and Mars , new research shows. As part of a recent investigation aboard the International Space Station, astronauts made cement in microgravity for the first time, showing that it can harden and develop in space.
2 giant blobs at the core of our galaxy are spewing radiation. Scientists don't know how they got there.
It's not easy to make big balls of hot gas. For starters, you need energy, and a lot of it. The kind of energy that can spread hot gas to a distance of over 25,000 light-years doesn't come easily to a typical galaxy. However, the peculiar orientation of the Fermi Bubbles -- extending evenly above and below our galactic center -- is a strong clue that they might be tied our central supermassive black hole, known as Sagittarius A*.
Saturn and Its Rings Look Truly Spectacular in This Hubble Telescope Portrait
NASA and the European Space Agency unveiled the new Saturn portrait today (Sept. 12). The image was taken on June 20 by Hubble's Wide Field Camera 3 as Saturn was about 845 million miles (1.36 billion kilometers) away. It's the second in a series of annual photos for the Outer Planets Legacy project by scientists studying the gas giant planets of our solar system.

NASA Puts Bigelow Aerospace's Giant Inflatable Space Habitat Prototype to the Test
The space agency is currently conducting a two-week ground test on Bigelow Aerospace's B330 habitat here at the company's headquarters. Eight NASA astronauts have participated in the trial so far, and four were on the scene Thursday (Sept. 12) to assess various aspects of the big, expandable module.
This Comet Might Be from Interstellar Space. Here's How We Could Find Out.
At first, it was just another bright, fuzzy speck in the sky. But it may turn out to be something much more exciting: the second known object to hurtle through our solar system after leaving another system. Astronomers will need a lot more observations before they can be confident giving the comet that title, but early data about the object seems promising.
Google banned employees from discussing politics at work, but the government now reportedly says that restricts free speech rights
The action came as a result of federal regulators reaching a settlement on employee complaints that the company restricts free speech, the Journal reported, citing sources familiar with the situation. The settlement, which was approved this week, ensures that Google will strike recently revised community guidelines that are meant to crack down on what employees can say inside the company.
This watery planet is the best place to hunt life we've seen so far
About 110 light years away is a planet twice Earth’s size with water vapour in its atmosphere, and it may be the best place to look for alien life that we have yet seen. The detection of water there marks the first time astronomers have characterised the atmosphere of a planet of this size.
