Located 100 million light-years away in the constellation Eridanus is the spiral galaxy NGC 1309. Swirling arms of blue star clusters, dark dust lanes and a glowing core. NASA / ESA’s Hubble Space Telescope captured this stunning image that not only shows the galaxy’s details but also hundreds of distant galaxies as tiny specks in the background. A Milky Way star with diffraction spikes near the top of the frame anchors our perspective in this vast scene.

Uranus, the solar system’s oddball, spins like a cosmic top 2.9 billion miles from the Sun, its pale blue glow faint. Long considered the coldest planet with an atmosphere, Voyager 2’s 1986 flyby showed it emitted no internal heat, unlike Jupiter, Saturn and Neptune. A 2025 study by NASA and Oxford University says otherwise, and it’s changing our understanding of this weird gas giant.
