Making Methane on Mars

This concept depicts astronauts and human habitats on Mars. NASA’s Mars 2020 rover will carry a number of technologies that could make Mars safer and easier to explore for humans. NASA

Among the many challenges with a Mars voyage, one of the most pressing is: How can you get enough fuel for the spacecraft to fly back to Earth?

Houlin Xin, an assistant professor in physics & astronomy, may have found a solution.

He and his team have discovered a more efficient way of creating methane-based rocket fuel theoretically on the surface of Mars, which can make the return trip all more feasible.

The novel discovery comes in the form of a single-atom zinc catalyst that will synthesize the current two-step process into a single-step reaction using a more compact and portable device.

Remote Sensing Data sheds light on when and how asteroid Ryugu lost its Water

Rocks on Ryugu, a ‘rubble pile’ near-Earth asteroid recently visited by Japan’s Hayabusa2 spacecraft, appear to have lost much of their water before they came together to form the asteroid, new research suggests.

Last month, Japan’s Hayabusa2 mission brought home a cache of rocks collected from near-Earth asteroid Ryugu. While analysis of those returned samples is just getting underway, researchers are using data from the spacecraft’s other instruments to reveal new details about the asteroid’s past.

In a study published in Nature Astronomy, researchers offer an explanation for why Ryugu isn’t quite as rich in water-bearing minerals as some other asteroids...

BISTRO explores complex Magnetic Field structure of Cat’s Paw Nebula

An international team of astronomers has investigated a nearby emission nebula and star-forming region dubbed the Cat’s Paw Nebula as part of the B-field In STar-forming Region Observations (BISTRO) survey. Results of this study, presented in a paper published December 24 on arXiv.org, provide essential information about the structure of the object’s complex magnetic field.

At a distance of some 4,240 light years away, the Cat’s Paw Nebula (other designations: NGC 6334, Gum 64) is a high-mass star-forming complex that lies within the galactic plane. The nebula has a form of a filamentary cloud structure spanning 1,000 light years and hosts several star-forming regions.

Observations show that NGC 6334 is dominated by both a dense ridge threaded by sub-filaments, and by two hub-li...

A Giant Black Hole keeps Evading Detection and scientists can’t explain it

This composite image of the galaxy cluster Abell 2261 contains optical data from NASA's Hubble Space Telescope and Japan's Subaru Telescope showing galaxies in the cluster and in the background, and data from NASA's Chandra X-ray Observatory showing hot gas (colored pink) pervading the cluster. The middle of the image shows the large elliptical galaxy in the center of the cluster.

An enormous black hole keeps slipping through astronomers’ nets. Supermassive black holes are thought to lurk at the hearts of most, if not all, galaxies...
