Hubble Lights the Way with New Multiwavelength Galaxy View
This image from the NASA/ESA Hubble Space Telescope features the galaxy NGC 1559. ESA/Hubble & NASA, F. Belfiore, W. Yuan, J. Lee and the PHANGS-HST Team, A. Riess, K. Takáts, D. de Martin & M. Zamani (ESA/Hubble) The magnificent galaxy featured in this NASA/ESA Hubble Space Telescope image is NGC 1559. It is a barred spiral galaxy located in the constellation Reticulum, approximately 35 million light-years from Earth. The brilliant light captured in the current image offers a wealth of information.
This picture is composed of a whopping ten different Hubble images, each filtered to collect light from a specific wavelength or range of wavelengths. It spans Hubble’s sensitivity to light, from ultraviolet through visible light and into the near-infrared spectrum. Capturing such a wide range of wavelengths allows astronomers to study information about many different astrophysical processes in the galaxy: one notable example is the red 656-nanometer filter used here. Ionized hydrogen atoms emit light at this particular wavelength, called H-alpha emission. New stars forming in a molecular cloud, made mostly of hydrogen gas, emit copious amounts of ultraviolet light that the cloud absorbs, ionizing the hydrogen gas causing it to glow with H-alpha light. Using Hubble’s filters to detect only H-alpha light provides a reliable way to detect areas of star formation (called H II regions). These regions are visible in this image as bright red and pink patches filling NGC 1559’s spiral arms.
These ten images come from six different Hubble observing programs, spanning from 2009 all the way up to 2024. Teams of astronomers from around the world proposed these programs with a variety of scientific goals, ranging from studying ionized gas and star formation, to following up on a supernova, to tracking variable stars as a contribution to calculating the Hubble constant. The data from all of these observations lives in the Hubble archive, available for anyone to use. This archive is regularly used to generate new science, but also to create spectacular images like this one! This new image of NGC 1559 is a reminder of the incredible opportunities that Hubble provided and continues to provide.
Along with Hubble’s observations, astronomers are using the NASA/ESA/CSA James Webb Space Telescope to continue researching this galaxy. This Webb image from February showcases the galaxy in near- and mid-infrared light.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
This artist’s concept depicts NASA’s Europa Clipper spacecraft in orbit around Jupiter. The mission is targeting an Oct. 10, 2024, launch.NASA/JPL-Caltech The first NASA spacecraft dedicated to studying an ocean world beyond Earth, Europa Clipper aims to find out if the ice-encased moon Europa could be habitable.
NASA’s Europa Clipper spacecraft, the largest the agency has ever built for a planetary mission, will travel 1.8 billion miles (2.9 billion kilometers) from the agency’s Kennedy Space Center in Florida to Europa, an intriguing icy moon of Jupiter. The spacecraft’s launch period opens Thursday, Oct. 10.
Learn more about how NASA’s Europa Clipper came together – and how it will explore an ocean moon of Jupiter. Credit: NASA/JPL-Caltech Data from previous NASA missions has provided scientists with strong evidence that an enormous salty ocean lies underneath the frozen surface of the moon. Europa Clipper will orbit Jupiter and conduct 49 close flybys of the moon to gather data needed to determine whether there are places below its thick frozen crust that could support life.
Here are eight things to know about the mission:
1. Europa is one of the most promising places to look for currently habitable conditions beyond Earth.
There’s scientific evidence that the ingredients for life — water, the right chemistry, and energy — may exist at Europa right now. This mission will gather the information scientists need to find out for sure. The moon may hold an internal ocean with twice the water of Earth’s oceans combined, and it may also host organic compounds and energy sources under its surface. If the mission determines that Europa is habitable, it would mean there may be more habitable worlds in our solar system and beyond than we have imagined.
2. The spacecraft will fly through one of the most punishing radiation environments in our solar system — second only to the Sun’s.
Jupiter is surrounded by a gigantic magnetic field 20,000 times stronger than Earth’s. As the field spins, it captures and accelerates charged particles, creating radiation that can damage spacecraft. Mission engineers designed a spacecraft vault to shield sensitive electronics from radiation, and they plotted orbits that will limit the time Europa Clipper spends in most radiation-heavy areas around Jupiter.
3. Europa Clipper will orbit Jupiter, studying Europa while flying by the moon dozens of times.
The spacecraft will make looping orbits around Jupiter that bring it close to Europa for 49 science-dedicated flybys. On each orbit, the spacecraft will spend less than a day in Jupiter’s dangerous radiation zone near Europa before zipping back out. Two to three weeks later, it will repeat the process, making another flyby.
4. Europa Clipper features NASA’s most sophisticated suite of science instruments yet.
To determine if Europa is habitable, Europa Clipper must assess the moon’s interior, composition, and geology. The spacecraft carries nine science instruments and a gravity experiment that uses the telecommunications system. In order to obtain the best science during each flyby, all the science instruments will operate simultaneously on every pass. Scientists will then layer the data together to paint a full picture of the moon.
5. With antennas and solar arrays fully deployed, Europa Clipper is the largest spacecraft NASA has ever developed for a planetary mission.
The spacecraft extends 100 feet (30.5 meters) from one end to the other and about 58 feet (17.6 meters) across. That’s bigger than a basketball court, thanks in large part to the solar arrays, which need to be huge so they can collect enough sunlight while near Jupiter to power the instruments, electronics, and other subsystems.
6. It’s a long journey to Jupiter.
Jupiter is on average some 480 million miles (about 770 million kilometers) from Earth; both planets are in motion, and a spacecraft can carry only a limited amount of fuel. Mission planners are sending Europa Clipper past Mars and then Earth, using the planets’ gravity as a slingshot to add speed to the spacecraft’s trek. After journeying about 1.8 billion miles (2.9 billion kilometers) over 5½ years, the spacecraft will fire its engines to enter orbit around Jupiter in 2030.
7. Institutions across the U.S. and Europe have contributed to Europa Clipper.
Currently, about a thousand people work on the mission, including more than 220 scientists from both the U.S. and Europe. Since the mission was officially approved in 2015, more than 4,000 people have contributed to Europa Clipper, including teams who work for contractors and subcontractors.
8. More than 2.6 million of us are riding along with the spacecraft, bringing greetings from one water world to another.
As part of a mission campaign called “Message in a Bottle,” the spacecraft is carrying a poem by U.S. Poet Laureate Ada Limón, cosigned by millions of people from nearly every country in the world. Their names have been stenciled onto a microchip attached to a tantalum metal plate that seals the spacecraft’s electronics vault. The plate also features waveforms of people saying the word “water” in over 100 spoken languages.
More About Europa Clipper
Europa Clipper’s three main science objectives are to determine the thickness of the moon’s icy shell and its 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.
Managed by Caltech in Pasadena, California, NASA’s Jet Propulsion Laboratory leads the development of the Europa Clipper mission in partnership with the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, for NASA’s Science Mission Directorate in Washington. The main spacecraft body was designed by APL in collaboration with JPL and NASA’s Goddard Space Flight Center in Greenbelt, Maryland, NASA’s Marshall Space Flight Center in Huntsville, Alabama, and NASA’s Langley Research Center in Hampton, Virginia. The Planetary Missions Program Office at Marshall executes program management of the Europa Clipper mission.
NASA’s Launch Services Program, based at Kennedy, manages the launch service for the Europa Clipper spacecraft, which will launch on a SpaceX Falcon Heavy rocket from Launch Complex 39A at Kennedy.

ESA/Webb, NASA & CSA, A. Scholz, K. Muzic, A. Langeveld, R. Jayawardhana NASA’s James Webb Space Telescope has infrared vision that lets us peer through the dusty veil of nearby star-forming region NGC 1333. We can see planetary mass objects, newborn stars, and brown dwarfs; some of the faintest ‘stars’ in this mosaic image are in fact newly born free-floating brown dwarfs with masses comparable to those of giant planets. The images were captured as part of a Webb observation program to survey a large portion of NGC 1333. These data constitute the first deep spectroscopic survey of the young cluster.
