Description:
From the heart of Desert Bloom Observatory, the night unveiled the ethereal dance of the Pleiades (M45)—a cluster of radiant sisters bound by gravity and myth. Draped in silken blue veils of cosmic dust, these stars shimmer across the constellation Taurus, about 444 light-years from Earth. Their reflection nebulae are illuminated by scattered starlight across interstellar dust—an elegant harmony between myth, matter, and light.

All data were acquired and processed by me at Desert Bloom Observatory. I sincerely hope this image reflects the quiet beauty and timeless mystery of the Pleiades star cluster.
This image from NASA's Spitzer Space Telescope shows infant stars "hatching" in the head of the hunter constellation, Orion. Astronomers suspect that shockwaves from a supernova explosion in Orion's head, nearly three million years ago, may have initiated this newfound birth.
The region featured in this Spitzer image is called Barnard 30. It is located approximately 1,300 light-years away and sits on the right side of Orion's head, just north of the massive star Lambda Orionis.
Wisps of green in the cloud are organic molecules called polycyclic aromatic hydrocarbons (PAHs). PAHs are formed anytime carbon-based materials are burned incompletely. On Earth, they can be found in the sooty exhaust from automobile and airplane engines. They also coat the grills where charcoal-broiled meats are cooked.
Tints of orange-red in the cloud are dust particles warmed by the newly forming stars. The reddish-pink dots at the top of the cloud are very young stars embedded in a cocoon of cosmic gas and dust. Blue spots throughout the image are background Milky Way along this line of sight.
This composite includes data from Spitzer's infrared array camera instrument, and multiband imaging photometer instrument. Light at 4.5 microns is shown as blue, 8.0 microns is green, and 24 microns is red.

James Webb Space Telescope — NIRCam | Program 9438
Deep within the crowded stellar fields of our Milky Way, the James Webb Space Telescope reveals a remarkable landscape of stars, interstellar dust, and intricate infrared structures in the region designated G054.093+01.748.
Located close to the Galactic plane, this field contains a dense population of stars seen through varying amounts of interstellar material. The striking contrast between the blue-white stars and the warm amber-colored clouds illustrates how observations at different infrared wavelengths reveal different components of the Galactic environment.
The diffuse orange and reddish structures trace infrared emission associated with interstellar material, while the numerous point-like sources reveal a rich stellar population, including stars that may be partially obscured by dust. The intricate eight-pointed diffraction spikes surrounding the brightest stars are characteristic of the James Webb Space Telescope's optical design.
This observation belongs to JWST Director's Discretionary Time Program 9438, “Certum: Multiband Webb Images in the Inner Galaxy for the Roman Galactic Plane Survey,” led by astronomer Eddie Schlafly. The program obtains multiband infrared imaging of selected regions of the inner Milky Way, providing valuable information about stellar populations, interstellar extinction, and the structure of our Galaxy.
The image presented here is an independently processed, eight-filter false-color composite constructed from publicly available JWST/NIRCam observations. Individual infrared wavelengths have been assigned visible colors in chromatic order, from blue and violet at shorter wavelengths to orange and red at longer wavelengths. These colors are representative rather than what the human eye would see.

Looking like a spider’s web swirled into a spiral, the galaxy IC 342 presents its delicate pattern of dust in this image from NASA’s Spitzer Space Telescope. Seen in infrared light, the faint starlight gives way to the glowing bright patterns of dust found throughout the galaxy’s disk.
At a distance of about 10 million light-years, IC 342 is relatively close by galaxy standards, however our vantage point places it directly behind the disk of our own Milky Way. The intervening dust makes it difficult to see in visible light, but infrared light penetrates this veil easily. It belongs to the same group as its even more obscured galaxy neighbor, Maffei 2.
IC 342 is nearly face-on to our view giving a clear, top-down view of the structure of its disk. It has a low surface brightness compared to other spirals, indicating a lower density of stars (seen here in blue). Its dust structures show up much more vividly (yellow-green).
New stars are forming in the disk at a healthy clip. Glowing like gems trapped in the web, regions of heavy star formation appear as yellow-red dots due to the glow of warm dust. The very center glows especially brightly in the infrared, highlighting an enormous burst of star formation occurring in this tiny region. To either side of the center, a small bar of dust and gas is helping to fuel this central star formation.
Data from Spitzer’s infrared array camera (IRAC) are shown in blue (3.6 and 4.5 microns) and green (5.8 and 8.0 microns) while the multiband imaging photometer (MIPS) observation is red (24 microns).
It was the first my girlfriend gift for my birthday, I still have it, it is portable multiband receiver.
This is my own home station -- an ICOM 7200, tuner, and my favorite keyer and paddle. Windows 7 is running on my mac in a virtual machine, with the N1MM logger software up and active. This station was connected (most of the time) to the 25' alpha-delta multiband dipole.
This swirling landscape of stars is known as the North America nebula. In visible light, the region resembles North America, but in this new infrared view from NASA's Spitzer Space Telescope, the continent disappears.
Where did the continent go? The reason you don't see it in Spitzer's view has to do, in part, with the fact that infrared light can penetrate dust whereas visible light cannot. Dusty, dark clouds in the visible image become transparent in Spitzer's view. In addition, Spitzer's infrared detectors pick up the glow of dusty cocoons enveloping baby stars.
Clusters of young stars (about one million years old) can be found throughout the image. Slightly older but still very young stars (about 3 to 5 million years) are also liberally scattered across the complex, with concentrations near the "head" region of the Pelican nebula, which is located to the right of the North America nebula (upper right portion of this picture).
Some areas of this nebula are still very thick with dust and appear dark even in Spitzer's view. For example, the dark "river" in the lower left-center of the image -- in the Gulf of Mexico region -- are likely to be the youngest stars in the complex (less than a million years old).
The Spitzer image contains data from both its infrared array camera and multiband imaging photometer. Light with a wavelength of 3.6 microns has been color-coded blue; 4.5-micron light is blue-green; 5.8-micron and 8.0-micron light are green; and 24-micron light is red.

This image layout reveals how the appearance of the North America nebula can change dramatically using different combinations of visible and infrared observations from the Digitized Sky Survey and NASA's Spitzer Space Telescope, respectively.
In this progression, the visible-light view (upper left) shows a striking similarity to the North America continent. The image highlights the eastern seaboard and Gulf of Mexico regions. The red region to the right is known as the "Pelican nebula," after its resemblance in visible light to a pelican.
The view at upper right includes both visible and infrared observations. The hot gas comprising the North America continent and the Pelican now takes on a vivid blue hue, while red colors display the infrared light. Inky black dust features start to glow in the infrared view.
In the bottom two images, only infrared light from Spitzer is shown -- data from the infrared array camera is on the left, and data from both the infrared array camera and the multiband imaging photometer, which sees longer wavelengths, is on the right. These pictures look different in part because infrared light can penetrate dust whereas visible light cannot. Dusty, dark clouds in the visible image become transparent in Spitzer's view. In addition, Spitzer's infrared detectors pick up the glow of dusty cocoons enveloping baby stars.
Color is used to display different parts of the spectrum in each of these images. In the visible-light view (upper right) from the Digitized Sky Survey, colors are shown in their natural blue and red hues. The combined visible/infrared image (upper left) shows visible light as blue, and infrared light as green and red. The infrared array camera (lower left) represents light with a wavelength of 3.6 microns as blue, 4.5 microns as green, 5.8 microns as orange, and 8.0 microns as red. In the final image, incorporating the multiband imaging photometer data, light with a wavelength of 3.6 microns has been color coded blue; 4.5-micron light is blue-green; 5.8-micron and 8.0-micron light are green; and 24-micron light is red.

The destructive results of a mighty supernova explosion reveal themselves in a delicate blend of infrared and X-ray light, as seen in this image from NASAs Spitzer Space Telescope and Chandra X-Ray Observatory, and the European Space Agency's XMM-Newton.
The bubbly cloud is an irregular shock wave, generated by a supernova that would have been witnessed on Earth 3,700 years ago. The remnant itself, called Puppis A, is around 7,000 light-years away, and the shock wave is about 10 light-years across.
The pastel hues in this image reveal that the infrared and X-ray structures trace each other closely. Warm dust particles are responsible for most of the infrared light wavelengths, assigned red and green colors in this view. Material heated by the supernovas shock wave emits X-rays, which are colored blue. Regions where the infrared and X-ray emissions blend together take on brighter, more pastel tones.
The shock wave appears to light up as it slams into surrounding clouds of dust and gas that fill the interstellar space in this region.
From the infrared glow, astronomers have found a total quantity of dust in the region equal to about a quarter of the mass of our sun. Data collected from Spitzers infrared spectrograph reveal how the shock wave is breaking apart the fragile dust grains that fill the surrounding space.
Supernova explosions forge the heavy elements that can provide the raw material from which future generations of stars and planets will form. Studying how supernova remnants expand into the galaxy and interact with other material provides critical clues into our own origins.
Infrared data from Spitzers multiband imaging photometer (MIPS) at wavelengths of 24 and 70 microns are rendered in green and red. X-ray data from XMM-Newton spanning an energy range of 0.3 to 8 keV (kiloelectron volts) are shown in blue.
This diagram highlights a slice of Saturn's largest ring. The ring (red band in inset photo) was discovered by NASA's Spitzer Space Telescope, which detected infrared light, or heat, from the dusty ring material. Spitzer viewed the ring edge-on from its Earth-trailing orbit around the sun.
The ring has a diameter equivalent to 300 Saturns lined up side to side. And it's thick too -- about 20 Saturns could fit into its vertical height. The ring is tilted about 27 degrees from Saturn's main ring plane.
The Spitzer data were taken by its multiband imaging photometer and show infrared light with a wavelength of 24 microns.
The picture of Saturn was taken by NASA's Hubble Space Telescope.
