This is an artist's concept looking down into the core of the giant elliptical galaxy M87. A supermassive black hole ejects a 3,000-light-year-long jet of plasma, traveling at nearly the speed of light. In the foreground, to the right is a binary star system. The system is far from the black hole, but in the vicinity of the jet. In the system an aging, swelled-up, normal star spills hydrogen onto a burned-out white dwarf companion star. As the hydrogen accumulates on the surface of the dwarf, it reaches a tipping point where it explodes like a hydrogen bomb. Novae frequently pop-off throughout the giant galaxy of 1 trillion stars, but those near the jet seem to explode more frequently. So far, it's anybody's guess why black hole jets enhance the rate of nova eruptions.

A comparison of JunoCam data from April 2024 with imagery from the Galileo mission of the same area in November 1997 (greyscale insert) reveals a new volcanic feature on the surface of Jupiter’s moon, Io.

The galaxy cluster MACS-J0417.5-1154 is so massive that it bends the fabric of space-time. This causes the appearance of galaxies behind it to be distorted, an effect known as gravitational lensing. This natural phenomenon magnifies distant galaxies and can also make them appear in an image multiple times, as NASA's James Webb Space Telescope has observed. In this image, two distant, interacting galaxies - a face-on spiral and a dusty red galaxy seen from the side - appear multiple times, tracing a familiar shape across the sky. The fact that these galaxies are actively forming stars and that the face-on galaxy's spiral shape is remarkably intact indicates that their interaction is just beginning.

In July 2024, NASA's Perseverance rover found "leopard spots" on a reddish rock called "Cheyava Falls" in Mars' Jezero Crater. Scientists suggest these spots might indicate that chemical reactions in the rock billions of years ago could have supported microbial life. Other explanations are also being explored.

NASA's Webb telescope captures a stunning image of the Serpens Nebula, revealing a cluster of baby stars in the top left corner. These stars are still forming and shooting out powerful jets of gas in a surprising, aligned pattern. Unlike some nebulae, Serpens doesn't create its own light. Instead, it glows by reflecting light from nearby stars.

An international team of astronomers has utilized NASA's James Webb Space Telescope to investigate the disk of gas and dust surrounding a young, low-mass star called ISO-ChaI 147. Their findings, depicted in this artist's impression, show the most diverse and abundant collection of carbon-containing molecules ever observed in a planet-forming disk around a star.
