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.

This artist's concept shows what the exoplanet 55 Cancri e could look like based on observations from NASA’s James Webb Space Telescope and other observatories. Observations from Webb’s NIRCam and MIRI suggest that the planet may be surrounded by an atmosphere rich in carbon dioxide (CO2) or carbon monoxide (CO). Researchers think the gases that make up the atmosphere could have bubbled out of an ocean of magma that is thought to cover the planet’s surface.

A 3D rendered image of the spiral galaxy NGC 4151, with a bright central region representing the active galactic nucleus. The image zooms in to show a glowing accretion disk surrounding a supermassive black hole, with twin jets of particles emanating from the disk's center. Colorful spectral lines are overlaid on the image, highlighting the iron fingerprints detected by XRISM's Resolve instrument.

This phase curve, captured by the MIRI low resolution spectrometer on NASA’s James Webb Space Telescope, shows the change in brightness of the WASP-43 system over time as the planet orbits its star. The system appears brightest when the hot dayside of the planet is facing the telescope, just before and after it passes behind the star. The system grows dimmer as the planet continues its orbits and the nightside rotates into view. It brightens again after passing in front of the star as the dayside rotates back into view. WASP-43 b is a hot Jupiter roughly 280 light-years away, in the constellation Sextans.

On the left is the starburst galaxy M82 as observed by NASA’s Hubble Space Telescope in 2006. The small box at the galaxy’s core corresponds to the area captured so far by the NIRCam (Near-Infrared Camera) instrument on NASA’s James Webb Space Telescope. The red filaments as seen by Webb are the polycyclic aromatic hydrocarbon emission, which traces the shape of the galactic wind. In the Hubble image, light at .814 microns is colored red, .658 microns is red-orange, .555 microns is green, and .435 microns is blue (filters F814W, F658N, F555W, and F435W, respectively). In the Webb image, light at 3.35 microns is colored red, 2.50 microns is green, and 1.64 microns is blue (filters F335M, F250M, and F164N, respectively). NASA, ESA, CSA, STScI, A.

The ULLYSES program studied two types of young stars: super-hot, massive, blue stars and cooler, redder, less massive stars than our Sun. The top panel is a Hubble Space Telescope image of a star-forming region containing massive, young, blue stars in 30 Doradus, the Tarantula Nebula. Located within the Large Magellanic Cloud, this is one of the regions observed by ULLYSES. The bottom panel shows an artist's concept of a cooler, redder, young star that's less massive than our Sun. This type of star is still gathering material from its surrounding, planet-forming disk.
