A side-by-side image showing opposite sides of Jupiter. At the top, left corner of the left-hand image is the label Jupiter. Centered at the bottom is the label January 5, 2024. The planet is banded in stripes of brownish orange, light gray, soft yellow, and shades of cream. Many large storms and small white clouds punctuate the planet. The largest storm, the Great Red Spot, is the most prominent feature in the left bottom third of this view. To its lower right is a smaller reddish anticyclone, Red Spot Jr. Another small red anticyclone appears near the top center of the image. On the right panel, centered at the bottom is the label January 6, 2024. This opposite side of Jupiter is also banded in stripes of brownish orange, light gray, soft yellow, and shades of cream with many large storms and small white clouds punctuating the planet. At upper right of center, a pair of storms appear next to each other: a deep-red triangle-shaped cyclone and a reddish anticyclone. Toward the far-left edge of this view is Jupiter's tiny moon Io. The variegated orange color is where volcanic outflow deposits are seen on Io’s surface.

A face-on spiral galaxy with four spiral arms that curve outward in a counterclockwise direction. The spiral arms are filled with young, blue stars and peppered with purplish star-forming regions that appear as small blobs. The middle of the galaxy is much brighter and more yellowish, and has a distinct narrow linear bar angled from 11 o’clock to 5 o’clock. Dozens of red background galaxies are scattered across the image. The background of space is black.

This is an artist's concept of the nearby exoplanet LTT 1445Ac, which is the size of Earth. The planet orbits a red dwarf star. The star is in a triple system, with two closely orbiting red dwarfs seen at upper right. The black dot in front of the bright light-red sphere at image center is planet LTT 1445Ac transiting the face of the star.

NASA’s Hubble Measures the Size of the Nearest Transiting Earth-Sized Planet

The diminutive planet, LTT 1445Ac, was first discovered by NASA's Transiting Exoplanet Survey Satellite (TESS) in 2022. But the geometry of the ...
