A blood moon is coming

On Friday 27 July there will be a total lunar eclipse, also known as a blood moon. The blood moon occurs when the sun, Earth and moon align perfectly, putting the moon in the Earth’s shadow. The red colouring is a result of sunlight refracting through the Earth’s atmosphere.

Five Teams Win a Share of $100,000 in 3D-Printed Habitat Competition

NASA and partner Bradley University of Peoria, Illinois, have selected the top five teams to share a $100,000 prize in the latest stage of the agency’s 3D-Printed Habitat Centennial Challenge competition. Winning teams successfully created digital representations of the physical and functional characteristics of a house on Mars using specialized software tools. The teams earned prize money based on scores assigned by a panel of subject matter experts from NASA, academia and industry. The judges interviewed and evaluated submissions from 18 teams from all over the world and selected these teams:

The 42 Biggest Questions About Life, the Universe, and Everything

In a recent paper published to arXiv, the physicists Roland Allen and Suzy Lidstrom, of Texas A&M and Uppsala University, respectively, tackled the question about the Question by describing what they believe to be the 42 ultimate questions of life, the universe, and everything.


In a homage to ‘Hitchhiker’s Guide to the Galaxy,’ two physicists explain the biggest unknowns in science. I’ve summed them up as a tweetstorm.

Engine test anomaly deals setback to Boeing’s plans for Starliner space taxi

Boeing confirms that it experienced an anomaly last month during tests of the engines that would be used on its CST-100 Starliner space taxi in the event of a launch emergency.

The anomaly resulted in an unwanted leak of propellant, and although no hardware was destroyed, the issue is likely to contribute to further delays for NASA’s plan to fly astronauts to and from the International Space Station on the Starliner.

Only Three Humans Have Died in Space: The Story of Soyuz 11

Space is brutally inhospitable to human life, so it’s a small wonder that out of the 561 people who have ventured beyond the safety of Earth, only three have died there. Many more have perished due to crashes or explosions when rocketing away from our planet or re-entering its atmosphere.

The three brave spacefarers who lost their lives in space were cosmonauts Georgy Dobrovolsky, Vladislav Volkov, and Viktor Patsayev. All three died on the Soyuz 11 mission of Jun 1971.
