Hubble Seeks Clusters in ‘Lost Galaxy’ This NASA/ESA Hubble Space Telescope image features the spiral galaxy NGC 4535. ESA/Hubble & NASA, F. Belfiore, J. Lee and the PHANGS-HST TeamToday’s NASA/ESA Hubble Space Telescope image features the spiral galaxy NGC 4535, which is situated about 50 million light-years away in the constellation Virgo (the Maiden). Through a small telescope, this galaxy appears extremely faint, giving it the nickname ‘Lost Galaxy’. With a mirror spanning nearly eight feet (2.4 meters) across and its location above Earth’s light-obscuring atmosphere, Hubble can easily observe dim galaxies like NGC 4535 and pick out features like its massive spiral arms and central bar of stars.
This image features NGC 4535’s young star clusters, which dot the galaxy’s spiral arms. Glowing-pink clouds surround many of these bright-blue star groupings. These clouds, called H II (‘H-two’) regions, are a sign that the galaxy is home to especially young, hot, and massive stars that blaze with high-energy radiation. Such massive stars shake up their surroundings by heating their birth clouds with powerful stellar winds, eventually exploding as supernovae.
The image incorporates data from an observing program designed to catalog roughly 50,000 H II regions in nearby star-forming galaxies like NGC 4535. Hubble released a previous image of NGC 4535 in 2021. Both the 2021 image and this new image incorporate observations from the PHANGS observing program, which seeks to understand the connections between young stars and cold gas. Today’s image adds a new dimension to our understanding of NGC 4535 by capturing the brilliant red glow of the nebulae that encircle massive stars in their first few million years of life.

Earth from Space: The Danakil Depression
Marking one year until BepiColombo reaches Mercury
The ESA/JAXA BepiColombo mission has been cruising towards Mercury since October 2018. With just one year to go until it arrives at its destination, what has the mission achieved so far? And what can we expect from its two spacecraft after they enter orbit around the Solar System’s smallest and least-explored rocky planet?

Europa Clipper Captures Uranus With Star Tracker Camera

Description
NASA’s Europa Clipper captured this image of a starfield — and the planet Uranus — on Nov. 5, 2025, while experimenting with one of its two stellar reference units. These star-tracking cameras are used for maintaining spacecraft orientation. Within the camera’s field of view — representing 0.1% of the full sky around the spacecraft — Uranus is visible as a larger dot near the left side of the image.
Figure A is an annotated version of the image with Uranus and several background stars labeled. NASA/JPL-Caltech Figure B is an animated GIF made of a pair of images taken 10 hours apart. In this version, Uranus can be seen moving very slightly, relative to the background stars. NASA/JPL-CaltechAt the time the images were taken, Europa Clipper was about 2 billion miles (3.2 billion kilometers) from Uranus. The spacecraft is currently en route to the Jupiter system to study the icy moon Europa.
Europa Clipper launched in October 2024 and will arrive at the Jupiter system in 2030 to conduct about 50 flybys of Europa. The mission’s main science goal is to determine whether there are places below Europa’s surface that could support life. The mission’s three main science objectives are to determine the thickness of the moon’s icy shell and its surface interactions with the ocean below, to investigate its composition, and to characterize its geology. The mission’s detailed exploration of Europa will help scientists better understand the astrobiological potential for habitable worlds beyond our planet.
