Members of NASA’s Perseverance Mars rover team watch in mission control as the first images arrive moments after the spacecraft successfully touched down on Mars, Thursday, Feb. 18, 2021, at NASA's Jet Propulsion Laboratory in Pasadena, California. A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith.

A hint of new physics in polarized radiation from the early Universe

fig.1_0.png
Figure: As the light of the cosmic microwave background emitted 13.8 billion years ago (left image) travels through the Universe until observed on Earth (right image), the direction in which the electromagnetic wave oscillates (orange line) is rotated by an angle β. The rotation could be caused by dark matter or dark energy interacting with the light of the cosmic microwave background, which changes the patterns of polarization (black lines inside the images). The red and blue regions in the images show hot and cold regions of the cosmic microwave background, respectively.
