That star is Vega in the constellation Lyra the Harp, which marks the solar apex, or direction of the sun’s motion through the Milky Way galaxy.

Earth in a tunnel
An astronomer at the Dunlap Institute at the University of Toronto said on October 14, 2021, that our solar system may be surrounded by what she describes as a magnetic tunnel, visible in radio waves. Jennifer West is an expert in magnetism in galaxies and the interstellar medium, that is, the material that fills the space between the stars. She is making a scientific case for the existence of this tunnel. She and her team believe that two known structures – seen on opposite sides of Earth’s sky and previously considered to be separate – are instead connected as ...
