This side-by-side view shows the same object, the Pillars of Creation, as captured by JWST in both mid-infrared light (at left) and in near-infrared light (at right). Note the different features revealed as far as stars, dust, gas, and other features within the nebula. Different wavelengths are sensitive to different types of features, including for features beyond the limits of JWST.\n<\/p>\n

This almost-perfectly-aligned image composite shows the first JWST deep field\u2019s view of the core of cluster SMACS 0723 and contrasts it with the older Hubble view. The JWST image of galaxy cluster SMACS 0723 is the first full-color, multiwavelength science image taken by the JWST. It was, for a time, the deepest image ever taken of the ultra-distant Universe, with 87 ultra-distant galaxy candidates identified within it. Most are still awaiting spectroscopic follow-up and confirmation to determine how distant they truly are.\n<\/p>\n

This extremely young star cluster began forming stars only within the last 3 million years, making it one of the youngest star clusters known in existence. The orange color, to JWST\u2019s eyes, represents gas that glows with heat in the infrared, powered by outflows from young, massive Herbig-Haro objects.\n<\/p>\n

<\/p>\n

This nebula in the Perseus molecular cloud, NGC 1333, is located only 960 light-years away here in our own Milky Way. While Hubble can only capture the light-blocking dust and heated gaseous material, JWST is spectacular at viewing an enormous number of obscured stars and cooler material that is invisible to Hubble.\n<\/p>\n

The spiral galaxy NGC 2566, located approximately 76 million light-years away, is one of 55 relatively nearby galaxies studied as part of a JWST program to understand the relationship between stars, gas, and dust in galaxies that are actively forming new stars. Many wispy structures are seen in red, highlighting the presence of dust, while blue colors highlight the presence of stars. In green and yellow, background galaxies galore can also be spotted.\n<\/p>\n

This spectacular Hubble view of galaxy NGC 2566 may be more familiar than the JWST view of the same object, showcasing a central bar and dust lane, followed by a circular concentration of newborn stars glowing in blue with pink ionized regions highlighting the presence of heated hydrogen. Nevertheless, many features, like the dust distribution, cannot be seen by Hubble; they require JWST\u2019s longer-wavelength, infrared sensitivities.\n<\/p>\n

While Hubble excels at imaging stars<\/a>, JWST reveals cold gas, warm dust, and more.<\/p>\n

What appears to be a swirling lake of light around a central core is actually two separate objects: a foreground elliptical galaxy with a distant lensed spiral galaxy wrapped around it. The ultra-distant spiral galaxy, due to the lensing magnification effects of the foreground mass, can have its individual internal structures revealed, including individual star clusters and galactic features that would be too faint and distant to be revealed without the presence of the lens.\n<\/p>\n

This ultra-deep view of massive galaxy cluster Abell S1063 was acquired with an impressive 120 hours of JWST observing time across 9 different near-infrared wavelengths of light. The colors represent relative wavelengths, with the reddest objects highlighting the most distant background galaxies lensed by the massive foreground cluster. The same background galaxies appear multiple times in the same image: a consequence of strong gravitational lensing.\n<\/p>\n

\"Image<\/p>\n

The galaxy cluster Abell S1063 was also observed by Hubble, in addition to JWST. Whereas Hubble can reveal some of the lensing features that JWST sees, most are invisible: a consequence of Hubble\u2019s inferior size and wavelength sensitivity, requiring more observing time for a lower-resolution view that cannot see the reddest or most redshifted objects that JWST can reveal.\n<\/p>\n

Perhaps the most spectacular gravitational lens ever, JWST\u2019s views far surpass Hubble\u2019s<\/a>.<\/p>\n

\"Hubble<\/p>\n

This planet-forming protoplanetary disk, IRAS 04302+2247, is one of the closest examples of a protostar with a protoplanetary disk to Earth: just 525 light-years away. JWST reveals a streak of dusty gas that represents a protoplanetary disk, while the bipolar ejects shows protostellar material being blown away perpendicular to the disk. There is likely a combination of inflows and outflows occurring here, making it difficult to know how massive the star at the center will ultimately become.\n<\/p>\n

This close-up view of the central portion of the protoplanetary system IRAS 04302+2247 showcases the motion of gaseous material away from the central protostar, while accreting material from within the disk is particularly dust-rich, obscuring even JWST\u2019s views of the central protostar. Dense objects, such as at the bottom of the protoplanetary disk, are actually background galaxies: visible even in these complex environments due to JWST\u2019s unique sensitivity.\n<\/p>\n

Aside from the Magellanic Clouds found here in the Local Group, these two dwarf galaxies, NGC 4490 and NGC 4485, are the closest pair of actively star-forming, interacting dwarf galaxies known to exist: at a distance of 24 million light-years away. The bridge of gas, dust, and stars connecting the two galaxies has never been revealed in the level of detail that JWST sees, while the internal stellar populations point to two recent episodes of star-formation: one 200 million years ago and then a more recent one 30 million years ago.\n<\/p>\n

A total of 10 separate Hubble observations, acquired between 2005 and 2015, were used to construct this image of nearby interacting dwarf galaxy NGC 4485, with its companion NGC 4490 located off-screen. The new stars and star clusters are visible here, but the gas and dust, and the bridge connecting it to its companion galaxy, are not revealed by Hubble\u2019s views.\n<\/p>\n

How are bipolar planetary nebulae, like the Red Spider Nebula shown here, shaped by the outflows and jets that emerge from the dying Sun-like star and any stellar companions found at the core of these regions? That\u2019s what a joint Chandra-JWST observing program was designed to reveal, with JWST providing imagery of the turbulent shapes that the blown-off material creates, far surpassing the extent and detail of earlier Hubble images.\n<\/p>\n

The two-lobed, bipolar planetary nebula known as the Red Spider Nebula was revealed by Hubble way back in 2001, showcasing big waves in the planetary nebula\u2019s ejecta. However, with JWST, we can see many additional turbulent features, and also find that these lobes extend for much farther and persist at much lower temperatures than Hubble\u2019s deep observations reveal.\n<\/p>\n

This glowing region, filled with wispy gas, dark red dust, and brilliant blue and white stars, lies inside the nebulous star cluster Westerlund 2, located 20,000 light-years away in the constellation of Carina, toward the galactic center. With JWST, it isn\u2019t only the bright stars that dominate, but cooler ones, brown dwarfs, and even planetary mass objects as small as the mass of several Jupiters. The infrared glow of that material, visible to JWST\u2019s NIRCam and\/or MIRI instruments, enables the detection of fainter, cooler objects than ever before.\n<\/p>\n

Released back in 2015, this spectacular Hubble image of Westerlund 2 was released to celebrate the 25th anniversary of the Hubble Space Telescope. The star cluster is visible at the upper right, while the surrounding nebulous dust and gas represents the site of continuing, ongoing star-formation. JWST can not only reveal what happens inside those still-star-forming clouds, but can find fainter, cooler, stellar and sub-stellar objects within the cluster than Hubble can ever hope to see.\n<\/p>\n
