This artist's concept shows what the gas giant orbiting Alpha Centauri A could look like. Observations of the triple-star system Alpha Centauri using NASA's James Webb Space Telescope indicate the potential gas giant, about the mass of Saturn, orbits the star by about two times the distance between the sun and Earth. In this concept, Alpha Centauri A is depicted at the upper left of the planet, while the other sun-like star in the system, Alpha Centauri B, is at the upper right. Our sun is shown as a small dot of light between those two stars. Credit: : NASA, ESA, CSA, STScI, R. Hurt (Caltech/IPAC)

The Hidden Edge of the Milky Way Is Alive with Star-Birthing Power

Hubble captured this image of the interstellar comet 3I/ATLAS on July 21, 2025, when the comet was 277 million miles from Earth. Hubble shows that the comet has a teardrop-shaped cocoon of dust coming off its solid, icy nucleus. Credit: NASA, ESA, David Jewitt (UCLA); Image Processing: Joseph DePasquale (STScI)
