Astronomers have watched as a black hole woke up from a decades-long slumber to feed on a low-mass object – either a brown dwarf or a giant planet – that strayed too close. A similar feeding event, albeit on a gas cloud, will soon happen at the black hole at the centre of our own Milky Way Galaxy.

Ozone stinks. People who breathe it gag as their lungs burn. The EPA classifies ground-level ozone as air pollution.
Yet without it, life on Earth would be impossible.
A fragile layer of ozone 25 km above Earth’s surface is all that stands between us and some of the harshest UV rays from the sun. The ozone molecule O3 blocks radiation … Read the rest of this article
A free ESA app released today turns a popular iPhone-controlled ‘home drone’ into a spacecraft. The augmented reality game lets owners of Parrot AR.Drone quadcopters attempt dockings with a simulated International Space Station while flying their drones for real – in the process helping to improve robotic rendezvous methods.

Since Europe’s Columbus laboratory module was attached to the International Space Station five years ago, it has offered researchers worldwide the opportunity to conduct science beyond the effects of gravity.
A total of 110 ESA-led experiments involving some 500 scientists have been conducted since 2008, spanning fluid physics, material sciences, radiation physics, the Sun, the human body, biology and astrobiology. … Read the rest of this article
NASA will host its first Google+ Hangout live with the International Space Station from 11 a.m. to noon EST, Friday, Feb. 22. This event will connect NASA’s social media followers with astronauts on the ground and living and working aboard the laboratory orbiting 240 miles above Earth.
Google+ Hangouts allow as many as 10 people to chat face-to-face, while thousands … Read the rest of this article
Living in space weakens astronauts’ immune systems, researchers have discovered. The findings are providing clues on how to tackle diseases on Earth before symptoms appear.
Ever since the first humans ventured into space we have known that astronauts can suffer from common infections that would be quickly dealt with by healthy people on Earth. Until now, it was not clear … Read the rest of this article
In 2012, NASA continued to implement America’s ambitious space exploration program, landing the most sophisticated rover on the surface of Mars, carrying out the first-ever commercial mission to the International Space Station and advancing the systems needed to send humans deeper into space.
“NASA achieved historic milestones this year landing the most sophisticated rover on the surface of Mars, carrying … Read the rest of this article
This weekend the International Space Station will turn itself to position ESA’s SOLAR instrument for a better view of the Sun. It will be the first time the Station has changed attitude for scientific reasons alone.

SOLAR consists of three complementary instruments: SOVIM (SOlar Variable and Irradiance Monitor) covers the near-ultraviolet, visible and thermal-infrared regions of the spectrum; SOL-ACES (SOLar …
On the 12th anniversary of crews continuously living and working aboard the International Space Station, NASA announced Friday a new service to help people see the orbiting laboratory when it passes overhead. “Spot the Station” will send an email or text message to those who sign up for the service a few hours before they will be able to see … Read the rest of this article
Thanks to ideas of putting swarms of tiny robot bugs to work on a future space station, patients being medicated for blood clots may soon get a simple, home-use testing kit, here on Earth.
