ALT This oval map shows the whole sky captured by NASA's TESS satellite. It has a grayish white band running across the image just left of center. Blue and orange dots speckle the image, representing confirmed and candidate exoplanets, respectively. A few black lines and arcs are visible in the image, the longest running near the edge from about 11 o\u2019clock to 3 o\u2019clock. There is a small, bright oval at the center.
