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.
Here are the biggest science stories of the week, told in 8 spectacular images.
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.
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.
