348-Year-Old Radioactive Molecule Spotted in Space
Posted by Genevieve Klien in categories: entertainment, space
“When Stars Collide” sounds like the title track of Barry Manilow’s latest album.
Unfortunately, Barry hasn’t released a single since 2012.

Allevi, Made in Space team up to develop first 3D bioprinter in space
Posted by Klaus Baldauf in categories: 3D printing, bioprinting, education, space
3D bioprinting company Allevi has teamed up with California-based 3D printing and space technology firm Made In Space to develop the Allevi ZeroG – the first 3D bioprinter capable of working in low-gravity conditions.
Allevi (formerly BioBots) was founded in 2014 by University of Pennsylvania graduates Ricardo Solorzano and Daniel Cabrera. At the time, the ambitious duo set out to develop an accessible desktop bioprinting system which could be used for a wide variety of research and educational applications.

Chinese Scientists Want to Capture a Small Asteroid and Land it on Earth
Posted by Shailesh Prasad in categories: robotics/AI, space
Space agencies have successfully studied asteroid and comets up close on several occasions, but capturing one for mining is also in the works. A group of Chinese scientists is looking to go a step further. Their ambitious plan involves not just capturing an asteroid, but bringing it down to the surface of Earth for study and mining.
This does sound pretty crazy on the face of it, but researchers from the National Space Science Center of the Chinese Academy of Sciences say it’s feasible. Researcher Li Mingtao and his team presented the idea at a conference to explore ideas for future technology in Shenzhen. Li says that the mission could focus on asteroids that cross Earth’s orbit, which could make them a potential hazard in the future. The Chinese plan could turn a hazard into a new source of rare materials.
The asteroids targeted by this project would be on the small side — probably just a few hundred tons. The first step is to send a fleet of small robotic probes to intercept the space rock. Then, they would deploy a “bag” of some sort that covers the asteroid, allowing the robots to slowly alter its course and steer it back to Earth.

Hubble Snapped Exquisite Photos of Mars and Saturn as They Passed Earth
Posted by Shailesh Prasad in category: space
Well lit and close to Earth this summer, Mars and Saturn got the crisp glamor shots that they so richly deserve, courtesy of the Hubble Space Telescope.
On June 27, Saturn’s orbit brought it into opposition with the Earth, meaning that the two planets were fully aligned with the sun, and as a consequence Saturn could reflect a maximum amount of sunlight back towards Earth. Hubble — NASA’s cheeky interstellar paparazzo and a non-sentient satellite containing imaging hardware — observed the planet on June 6, 2018, while it was about 870 million miles from Earth.
Due to Saturn’s tilt toward the Earth at this moment in its orbit, Hubble was able to very clearly image all of the bands and gaps that comprise Saturn’s rings: Moving inward from the outermost ring, these are known as the A ring, the Encke Gap, the Cassini Division, the B ring, and the C ring with the Maxwell Gap.

Astronomers Have Made The First Detection of a Radioactive Molecule in Space
Posted by Shailesh Prasad in category: space
After a long search, a cosmic mystery has an answer. Astronomers have made the very first unambiguous detection of a radioactive molecule in space — an isotope of aluminium, found in the heart of a rare nova.
Scientists have long been searching for 26 AlF — or Aluminium monofluoride — containing 26 Al, but a direct observation has been exceptionally illusive.
We’ve known about the presence of 26 Al in space for decades. In 1984, NASA’s HEAO 3 satellite data was used to identify gamma-ray radiation originating from the beta decay of the isotope. According to these observations, there’s roughly two solar masses of 26 Al in the Milky Way.

Indian priest discovers proof of long-lost galaxy. He’s also an astronomer
Posted by Michael Lance in category: space
This discovery and its method will now pave the way for the discovery of other galaxies that have been cannibalized by other larger galaxies.
The researcher discovers conclusive proof of a galaxy that was cannibalized by neighbouring Andromeda.

Putin’s robo-nauts ‘to be in space by 2019’
Posted by Dan Kummer in categories: robotics/AI, space
Russia is planning to blast two robot astronauts into space to work on the international space station.
Scientists have developed the advanced machines, named FEDOR, to conduct rescues — even though they have recently been recently trained to use firearms.
