Explanation: To some it looks like a cat’s eye. To others, perhaps like a giant cosmic conch shell. It is actually one of brightest and most highly detailed planetary nebula known, composed of gas expelled in the brief yet glorious phase near the end of life of a Sun-like star. This nebula’s dying central star may have produced the outer circular concentric shells by shrugging off outer layers in a series of regular convulsions. The formation of the beautiful, complex-yet-symmetric inner structures, however, is not well understood. The featured image is a composite of a digitally sharpened Hubble Space Telescope image with X-ray light captured by the orbiting Chandra Observatory. The exquisite floating space statue spans over half a light-year across. Of course, gazing into this Cat’s Eye, humanity may well be seeing the fate of our sun, destined to enter its own planetary nebula phase of evolution … in about 5 billion years.

Robotic “Bees” Are About to Join Astronauts in Space

There are some things only humans can do in space. The rest can be left to robots. To free up valuable time for astronauts living and working aboard the International Space Station, we’re sending three robotic helpers to the orbiting outpost. Developed and built at our Ames Research Center in California’s Silicon Valley, the cube-shaped Astrobee robots will each stay as busy as a bee flying around the space station and assisting crew with routine tasks like maintenance and tracking inventory. The robots will also help researchers on the ground carry out experiments, test new technologies and study human-robot interaction in space. Learning how robots can best work with humans in close proximity will be key for exploring the Moon and other destinations. Get to know more about our new robots headed to space: 

The Astrobee robots were tested inside a special lab at our Ames Research Center where researchers created a mockup of the space station’s interior. 

The flying robots are propelled by fans. They can move in any direction and turn on any axis in space. 

Each robot is equipped with cameras and sensors for navigating inside the space station and avoiding obstacles.

Claw power! Astrobees have a robotic arm that can be attached for handling cargo or running experiments.

Astrobee is battery powered. When its battery runs low, the robot will autonomously navigate and dock to a power station to recharge.

The robots can operate in either fully automated mode or under remote control by astronauts or researchers on Earth.

Astrobee builds on the success of SPHERES, our first-generation robotic assistant that arrived at the space station in 2006.  

Two of the three Astrobee robots are scheduled to launch to space this month from our Wallops Flight Facility in Virginia! Tune in to the launch at www.nasa.gov/live.

Amazing house

All right, so I believe that as chemist is my obligation to warn y'all about using homemade hand sanitizer or shit like that. So please just buy a bottle and if you can't, wash your hands always that possible. Take care 'cause alcohol-based hand sanitizers are flammable, so you know...

I'm saying this because here in Brazil there's some dick heads selling homemade hand sanitizers and uninformed people are buying it. Besides not disinfecting their hands properly, many are suffering burns due to the composition.

Anyway, stay home be safe and drink water.

Hard to argue science with conspiracy theorists

I like when an article thumbnail features a pic of a woman conductor, as it is the closest I will get to living in a world where newspapers write feel-good human-interest stories about a local witch who is proud to show off her new spell.
