The week of April 1–7 was full of developments in space science, from the first color photos taken by NASA’s Ingenuity helicopter to the discovery of two rare quasars.
Researchers from Northwestern University developed a new model for how whiskers bend within animals’ follicles, showing that they bend in an S or C shape. The finding could help scientists better understand the sensory signals whiskers provide.
NASA began final preparations to ready its BioSentinel project for launch aboard Artemis I. BioSentinel will conduct the first long-term tests of deep space radiation on yeast cells, which could illuminate the risks for future humans in deep space.
The Perseverance rover recorded an image that appeared to show a rainbow on Mars. As NASA explained, rainbows are impossible on Mars due to the lack of water, and the streak of color in the sky was just a lens flare.
Scientists in Brazil developed a technique to reconstruct donor livers using the recipient’s cells, making otherwise unusable livers available for transplant and removing the risk of rejection.
NASA’s Ingenuity Mars helicopter sent back the first color images of Mars, taken on the floor of the Perseverance rover’s Jezero Crater landing site.
Scientists in China discovered a new species of venomous snake. They named it Bungarus suzhenae after the snake goddess Bai Su Zhen from Chinese folklore.
Researchers found two double quasars in pairs of merging galaxies using NASA’s Hubble Space Telescope. The researchers estimate that only one double quasar exists for every 1,000 quasars.
Researchers from Penn State published research they say resolves discrepancies between sub-atomic particles called muons and the standard model of physics. Further research could prove muons align with the model after all or point to yet-undiscovered physical forces.
