NASA Europa Clipper's Journey to Explore Jupiter's Moon

NASA Europa Clipper's Journey to Explore Jupiter's Moon

🛰️NASA's Europa Clipper, supported by Aerospace experts and validated through Aerospace testbeds, has embarked on a groundbreaking journey to explore Jupiter's moon Europa to investigate its icy shell, hidden ocean and potential for life. The spacecraft will enter the Jovian system in 2030 and conduct roughly 50 close flybys of Europa.

Learn how Aerospace's contributions are supporting the mission's voyage: https://lnkd.in/erwhDDMJ

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, JPL 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. APL designed the main spacecraft body in collaboration with JPL and NASA’s Goddard Space Flight Center in Greenbelt, Maryland, NASA’s Marshall Space Flight Center in Huntsville, Alabama, and 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, managed the launch service for the Europa Clipper spacecraft.

Saguaros and The Milky Way Galaxy: View from Arizona

Saguaros and The Milky Way Galaxy: View from Arizona

The Milky Way galaxy arcs above two saguaro cactuses in this image captured near Tucson, Arizona.

The saguaro (Carnegiea gigantea) is a tree-like cactus species in the monotypic genus Carnegiea that can grow to be over 12 meters (40 feet) tall. It is native to the Sonoran Desert in Arizona, the Mexican state of Sonora, and the Whipple Mountains and Imperial County areas of California. Saguaro typically grow at elevations ranging from sea level to 4,500', although they may be found at up to 5,000'. The saguaro blossom is the state wildflower of Arizona. Its scientific name is given in honor of Andrew Carnegie. In 1933, Saguaro National Park, near Tucson, Arizona, was designated to help protect this species and its habitat.

Arizona is a landlocked state in the Southwestern region of the United States, sharing the Four Corners region of the western United States with Colorado, New Mexico, and Utah. It also borders Nevada to the northwest and California to the west, and shares an international border with the Mexican states of Sonora and Baja California to the south and southwest.

NASA’s Nancy Grace Roman Space Telescope: Widening Our Gaze | NASA Goddard

NASA’s Nancy Grace Roman Space Telescope: Widening Our Gaze | NASA Goddard

The NASA Astrophysics fleet of spacecraft has an impressive range of capabilities. What is the next step in exploring the cosmos? The Nancy Grace Roman Space Telescope, NASA’s upcoming flagship mission, will take Hubble’s resolution and widen its infrared view to more than 100 times the coverage in every single image. Roman is a survey telescope that can peer through the Milky Way’s obscuring dust, and see faint, distant galaxies. Roman’s rigid design allows it to scan large regions of sky very quickly. Hubble would take 1,000 years to observe what Roman can see in one. Roman’s 18 4k x 4k detectors create 300-megapixel images covering an area of sky slightly larger than the full Moon. Roman will also look at the same regions of space repeatedly over time, allowing astronomers to see changes and observe temporary events like supernovae. Roman’s surveys of deep space and the center of our Milky Way galaxy will find thousands of new exoplanets, survey millions of galaxies, help us understand dark matter and dark energy, and learn more about the evolution of the universe.

Large Circumstellar Disc IRAS 23077+6707 in Cepheus | Hubble

Large Circumstellar Disc IRAS 23077+6707 in Cepheus | Hubble


This NASA/European Space Agency Hubble Space Telescope image shows the largest planet-forming disc ever observed around a young star. It spans nearly 640 billion kilometers, roughly 40 times the diameter of our Solar System. Tilted nearly edge-on as seen from Earth, the dark, dusty disk resembles a hamburger. Hubble reveals it to be unusually chaotic with bright wisps of material extending far above and below the disk—more than seen in any similar circumstellar disk. Cataloged as IRAS 23077+6707, the system is located approximately 1,000 light-years from Earth in the constellation Cepheus. The discovery marks a new milestone for Hubble and offers fresh insight into planet formation in extreme environments across the galaxy.

Image Description: Near the center is an object that resembles an edge-on view of a hamburger. There is a diagonal dark strip (the meat patty) of dust, running from 1 o’clock to 7 o’clock, that obscures a central star. Curving away from either side of the dark strip are glowing white clouds (the buns) where dust is reflecting starlight. Bright blue finger-like wisps of material extend far above and below the dark center plane. A few dozen stars, several with four diffraction spikes, are scattered on the black background of space.

Large Protoplanetary Disk Nicknamed “Dracula’s Chivito” | Hubble Space Telescope

Large Protoplanetary Disk Nicknamed “Dracula’s Chivito” | Hubble Space Telescope

Located roughly 1,000 light-years from Earth, this protoplanetary disk, nicknamed “Dracula’s Chivito,” spans nearly 400 billion miles, 40 times the diameter of the solar system to the outer edge of the Kuiper belt of cometary bodies.

Nicknamed “Dracula’s Chivito,” the disk’s playful name comes from its discoverers, one from Transylvania and another from Uruguay, where the national dish is a sandwich called a chivito.

Thanks to Hubble, we now can see this disk’s surprising scale and detail. Dracula’s Chivito is not just the largest protoplanetary disk ever imaged, it is also a window into how planets are born and how systems like ours began.

Cosmic Holiday Greetings! | NASA's Chandra X-ray Observatory [Budget Alert]

Cosmic Holiday Greetings! | NASA's Chandra X-ray Observatory [Budget Alert]

NASA’s Chandra X-ray Observatory is sending out a holiday card with four new images of cosmic wonders. Each of the quartet of objects evokes the winter season or one of its celebratory days, either in its name or shape.

Chandra’s seasonal greetings begin with NGC 4782 and NGC 4783, a pair of colliding galaxies that when oriented in a certain way resembles a snowman. The top and bottom of the snowman are each elliptical galaxies, separated by a distance of about 170 million light-years. The galaxies, seen in an image from NASA’s Hubble Space Telescope, are bound together through gravity. X-rays from Chandra show a bridge of hot gas between the two galaxies, like a winter scarf.

After the cosmic snowman is one of the most iconic symbols of the season, a Christmas tree. This celestial version takes an optical light image from an astrophotographer that shows the “branches” of NGC 2264, a relatively young nebula where new stars are forming. Within this cloud of gas and dust, baby stars appear as high-energy baubles in X-ray light from Chandra and XMM-Newton.

NASA's Chandra X-ray Observatory is being canceled in NASA's Fiscal Year 2026 Budget Request, along with 18 other active science missions. NASA's science budget is being reduced by nearly 50%. NASA's total budget will become the lowest since 1961, after accounting for inflation.

Contact your representatives in the United States Congress, House and Senate, to express your concerns about severe budget cuts at NASA:

The nebula NGC 6357 contains Pismis 24, a young cluster of stars about 5,500 light-years from Earth. This stellar landscape is reminiscent of a winter vista in a view from NASA’s James Webb Space Telescope. Chandra data punctuate the scene with bursts of colored lights representing high-energy activity from turbulent young stars.

The final image in this holiday card display is M78, a striking nebula in the Orion constellation that may also bring a partridge in the proverbial pear tree to mind. M78 is a reflection nebula, which is cloud interstellar dust that glows from the scattered light embedded within it. The bird-like structure is seen in infrared and optical light by Euclid while Chandra data provide speckled lights across the nebula.

Close-up: Arp 4—Galaxies with a Long-distance Relationship in Cetus | Hubble

Close-up: Arp 4—Galaxies with a Long-distance Relationship in Cetus | Hubble

These galaxies look to be close companions—a small, bright spiral galaxy flitting around the edge of a much larger spiral with a dark and disturbed countenance. However, looks can be deceiving—how close are they really? The celestial pair featured in this Hubble picture goes by the name Arp 4, and lies in the constellation Cetus (the Whale).

The designation Arp 4 comes from the Atlas of Peculiar Galaxies, compiled in the 1960s by astronomer Halton Arp. “Unusual galaxies” were selected and photographed to provide examples of weird and non-standard shapes, the better to study how galaxies evolve into these forms. Throughout its mission the Hubble Space Telescope has revolutionized the study of galaxies and shown us fantastically unusual examples from Arp’s atlas. In that catalog, the first few galaxies like Arp 4 are “low surface brightness” galaxies, a type of galaxy that is unexpectedly faint and hard to detect. The large galaxy here—also cataloged as MCG-02-05-050—fits this description well, with its fragmentary arms and dim disc. Its smaller companion, MCG-02-05-050a, is a much more bright and active spiral.

The trick is that these galaxies are not actually very close. The large blue galaxy MCG-02-05-050 is located 65 million light-years from Earth; its brighter smaller companion MCG-02-05-050a, at 675 million light-years away, is over ten times the distance! Owing to this, MCG-02-05-050a is likely the larger galaxy of the two, and MCG-02-05-050 comparatively small. Their pairing in this image is simply an unlikely visual coincidence. Despite this lack of a physical relation between them, our point of view on Earth allows us to enjoy the sight of Arp 4 as an odd couple in the sky.

Image Description: This image shows two galaxies side by side. The galaxy on the top left is smaller in size, and appears as a bright glowing spiral with clearly-defined arms. A larger blue galaxy dominates the full right field of the image. This galaxy is more irregularly shaped with a glowing central bar, and varying regions of concentrated hues of blue. The background is black with various stars and galaxies in the distance.

Close-up: Andromeda Galaxy (M31) | Subaru Telescope

Close-up: Andromeda Galaxy (M31) | Subaru Telescope

The Andromeda Galaxy (M31) captured by the Hyper Suprime-Cam (HSC), a wide-field optical imaging camera. HSC offers an ultra-wide field of view equivalent to nine full Moons, covering nearly the entire Andromeda Galaxy.

These pictures show how the Subaru Telescope and HSC work together to provide a wide field of view and sharp star images.

The Andromeda Galaxy is a barred spiral galaxy and is the nearest major galaxy to the Milky Way. It was originally named the Andromeda Nebula and is cataloged as Messier 31, M31, and NGC 224.

The Milky Way and Andromeda galaxies have about a 50% chance of colliding with each other in the next 10 billion years, merging to potentially form a giant elliptical galaxy or a large lenticular galaxy.

The Subaru Telescope is an astronomical observation facility operated by the National Astronomical Observatory of Japan (NAOJ). It is located at the summit of Mauna Kea at an altitude of 4,200 meters in the U.S. state of Hawaii.
