Twinkle, twinkle giant star, astronomers see how far you are

This image made available by NASA on Wednesday shows the star Earendel, indicated by arrow, and the Sunrise Arc galaxy, stretching from lower left to upper right, optically bent due to a massive galaxy cluster between it and the Hubble Space Telescope which captured the light. The mass of the galaxy cluster serves as a magnifying glass, allowing Earendel to be seen. (NASA, ESA, Brian Welch (JHU), Dan Coe (STScI); Image processing: NASA, ESA, Alyssa Pagan (STScI)/via AP)
