Hubble Captures Galaxy Cluster NASA’s Hubble Space Telescope captured this scene of galaxy cluster MACS J1141.6-1905 in visible and infrared light. NASA, ESA, H. Ebeling (University of Hawaii); Image Processing: G. Kober (NASA/Catholic University of America)Look closely at this image from NASA’s Hubble Space Telescope and you’ll see galaxies of various shapes and sizes clustered together toward the center-left of the image. A few foreground stars shine brightly and are easily distinguished by the spikes that appear to extend outward from each star. These spikes, called diffraction spikes, are the result of how point sources of light (such as stars) bend, or diffract, around the supports for Hubble’s secondary mirror.
Hubble captured this scene of MACS J1141.6-1905 in visible and infrared light. The image includes data from two Hubble observing programs that looked at massive galaxy clusters that shine very brightly in X-rays. Both programs were looking for distant galaxies gravitationally lensed by the cluster. They also wanted to better understand the physical nature of interactions at each cluster’s core. An extra bonus was the addition of Hubble’s visible and infrared observations of these very bright X-ray clusters to its archive.
Hubble’s archive of 1.7 million observations, and counting, is a valuable tool for current and future astronomers. They can mine Hubble’s 36 years of observations and examine the data with new tools, enabling researchers to make new discoveries.
MACS J1141.6-1905 is around four billion light-years away in the constellation Crater (the Cup).

Both Hemispheres of 3I/ATLAS Observed Simultaneously by JUICE and Europa Clipper
The Southwest Research Institute-led Ultraviolet Spectrograph (UVS) instruments aboard ESA’s Jupiter Icy Moons Explorer (Juice) spacecraft and NASA’s Europa Clipper made unique observations of interstellar comet 3I/ATLAS in late 2025. SwRI leads the UVS instruments on both spacecraft, simultaneously imaging both hemispheres of the comet and detecting the comet’s ultraviolet emissions.

NASA to Showcase Mission to Boost Swift Spacecraft’s Orbit
Media are invited to NASA’s Wallops Flight Facility in Virginia on Wednesday, June 17, to view Northrop Grumman’s Pegasus XL rocket, carrying a Katalyst robotic spacecraft that will attempt to boost the orbit of NASA’s Neil Gehrels Swift Observatory.
Katalyst’s robotic servicing spacecraft, called LINK, will launch on Pegasus in June to rendezvous with Swift and raise its altitude, extending its science mission lifespan.
Both United States and international media may apply for onsite credentials to view the Pegasus and the L-1011 Stargazer aircraft that will deploy the rocket at launch. In addition to interview opportunities on site, media also will receive images and video of LINK, as the spacecraft already will be encapsulated in the rocket.
NASA and Katalyst also will host an audio-only media teleconference on June 17 to preview the mission to boost Swift’s orbit. Audio of the media teleconference will stream live on NASA’s YouTube channel. Information about timing and teleconference participants will be shared closer to the event.
The application deadline for U.S. citizens to attend in person is 4 p.m. EDT, Wednesday, June 10. International media without U.S. citizenship must apply by 3 p.m. EDT, Wednesday, May 27. NASA’s media accreditation policy is available online.
Media requesting to participate in person or join the media call must send their accreditation requests to Amy Barra at: amy.l.barra@nasa.gov, with the following information:
- Legal first and last name (must match government identification)
- Phone number
- Job title and organization
- Citizenship
The Swift mission, which launched in 2004, leads NASA’s fleet of space telescopes in studying changes in the high-energy universe. It studies gamma-ray bursts — the most powerful explosions in the universe — and other cosmic objects and events. When a rapid, sudden event takes place in the cosmos, Swift serves as a “dispatcher,” providing critical information that allows other “first responder” missions to follow up to learn more about how the universe works.
