Edited Spitzer Space Telescope image of the supernova remnant G54.1+0.3. Inverted grayscale variant.
Image source: www.spitzer.caltech.edu/news/2121-ssc2018-16-Exploding-St...
Original caption: This image of supernova remnant G54.1+0.3 includes radio, infrared and X-ray light.
The saturated yellow point at the center of the image indicates strong X-ray source at the center of the supernova remnant. This is an incredibly dense object called a neutron star, which can form as a star runs out of fuel to keep it inflated, and the unsupported material collapses down on to the star's core. G54.1+0.3 contains a special type of neutron star called a pulsar, which emits particularly bright radio and X-ray emissions.
The blue and green emissions show the presence of dust, including silica.
The red hues correspond to radio data from the Karl G. Jansky Very Large Array; green corresponds to 70 m wavelength infrared light from the European Space Agency's Herschel Space Observatory; blue corresponds to 24 m wavelength infrared light from the Multiband Imaging Photometer (MIPS) instrument on NASA's Spitzer Space Telescope; yellow corresponds to X-ray data from the Chandra X-ray Observatory.
This glowing emerald nebula seen by NASA's Spitzer Space Telescope has been sculpted by the powerful light of giant "O" stars. O stars are the most massive type of star known to exist.
Named RCW 120, this region of hot gas and glowing dust can be found in the murky clouds encircled by the tail of the constellation Scorpius. The ring of dust is actually glowing in infrared colors that our eyes cannot see, but show up brightly when viewed by Spitzer's infrared detectors. At the center of this ring are a couple of giant stars whose intense ultraviolet light has carved out the bubble, though they blend in with other stars when viewed in infrared.
This bubble is far from unique; Spitzer has found that such bubbles are common and can be found around O stars throughout our Milky Way galaxy. The small objects at the lower right area of the image may themselves be similar regions seen at much greater distances across the galaxy.
Rings like this are so common in Spitzer's observations that astronomers have even enlisted the help of the public to help them find and catalog them all. Anyone interested in joining the search as a citizen scientist can visit "The Milky Way Project," part of the "Zooniverse" of public astronomy projects, at www.milkywayproject.org/ .
RCW 120 can be found slightly above the flat plane of our galaxy, located toward the bottom of the picture. The green haze seen here is the diffuse glow of dust from the galactic plane.
This is a three-color composite that shows infrared observations from two Spitzer instruments. Blue represents 3.6-micron light and green shows light of 8 microns, both captured by Spitzer's infrared array camera. Red is 24-micron light detected by Spitzer's multiband imaging photometer.

The infrared portrait of the Small Magellanic Cloud, taken by NASA's Spitzer Space Telescope, reveals the stars and dust in this galaxy as never seen before. The Small Magellanic Cloud is a nearby satellite galaxy to our Milky Way galaxy, approximately 200,000 light-years away.
The image shows the main body of the Small Magellanic Cloud, which is comprised of the "bar" on the left and a "wing" extending to the right. The bar contains both old stars (in blue) and young stars lighting up their natal dust (green/red). The wing mainly contains young stars. In addition, the image contains a galactic globular cluster in the lower left (blue cluster of stars) and emission from dust in our own galaxy (green in the upper right and lower right corners).
The data in this image are being used by astronomers to study the lifecycle of dust in the entire galaxy: from the formation in stellar atmospheres, to the reservoir containing the present day interstellar medium, and the dust consumed in forming new stars. The dust being formed in old, evolved stars (blue stars with a red tinge) is measured using mid-infrared wavelengths. The present day interstellar dust is weighed by measuring the intensity and color of emission at longer infrared wavelengths. The rate at which the raw material is being consumed is determined by studying ionized gas regions and the younger stars (yellow/red extended regions). The Small Magellanic Cloud, and its companion galaxy the Large Magellanic Cloud, are the two galaxies where this type of study is possible, and the research could not be done without Spitzer.
This image was captured by Spitzer's infrared array camera and multiband imaging photometer (blue is 3.6-micron light; green is 8.0 microns; and red is combination of 24-, 70- and 160-micron light). The blue color mainly traces old stars. The green color traces emission from organic dust grains (mainly polycyclic aromatic hydrocarbons). The red traces emission from larger, cooler dust grains.
The image was taken as part of the Spitzer Legacy program known as SAGE-SMC: Surveying the Agents of Galaxy Evolution in the Tidally-Stripped, Low Metallicity Small Magellanic Cloud.

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.

This swirling landscape of stars is known as the North American 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 American 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 infrared image from NASA's Spitzer Space Telescope shows the Helix nebula, a cosmic starlet often photographed by amateur astronomers for its vivid colors and eerie resemblance to a giant eye.
The nebula, located about 700 light-years away in the constellation Aquarius, belongs to a class of objects called planetary nebulae. Discovered in the 18th century, these cosmic butterflies were named for their resemblance to gas-giant planets.
Planetary nebulae are actually the remains of stars that once looked a lot like our sun.
When sun-like stars die, they puff out their outer gaseous layers. These layers are heated by the hot core of the dead star, called a white dwarf, and shine with infrared and visible-light colors. Our own sun will blossom into a planetary nebula when it dies in about five billion years.
In Spitzer's infrared view of the Helix nebula, the eye looks more like that of a green monster's. Infrared light from the outer gaseous layers is represented in blues and greens. The white dwarf is visible as a tiny white dot in the center of the picture. The red color in the middle of the eye denotes the final layers of gas blown out when the star died.
The brighter red circle in the very center is the glow of a dusty disk circling the white dwarf (the disk itself is too small to be resolved). This dust, discovered by Spitzer's infrared heat-seeking vision, was most likely kicked up by comets that survived the death of their star. Before the star died, its comets and possibly planets would have orbited the star in an orderly fashion. But when the star blew off its outer layers, the icy bodies and outer planets would have been tossed about and into each other, resulting in an ongoing cosmic dust storm. Any inner planets in the system would have burned up or been swallowed as their dying star expanded.
The Helix nebula is one of only a few dead-star systems in which evidence for comet survivors has been found.
This image is made up of data from Spitzer's infrared array camera and multiband imaging photometer. Blue shows infrared light of 3.6 to 4.5 microns; green shows infrared light of 5.8 to 8 microns; and red shows infrared light of 24 microns.

Tribute to Billy Ruane a rocking affair
news.bostonherald.com/entertainment/music/general/view/20...
By Jim Sullivan
Friday, November 19, 2010 - Updated 1 week ago
Billy Ruane was a whirlwind of energy, an avid music enthusiast and something of a madman. He was a galvanizing, if occasionally polarizing, figure on the Boston rock scene for three decades.
Ruane promoted shows and danced with reckless abandon all over town. At various times, he was banned from two of his favorite clubs, the Middle East and T.T. the Bear’s Place, for his over-the-top antics.
Wednesday night, the life of Ruane - who died from a heart attack last month at 52 - was celebrated at both clubs with a multiband concert.
He had planned a similar celebration for his Nov. 10 birthday. After his death, his longtime friend, singer Mary Lou Lord, organized an expanded gathering for an Irish wake-styled memorial. The local rock community made it a sellout. Lord predicted “chaos of epic proportions,” adding that “Billy wouldn’t have it any other way.”
Chaos there was. Not everything went off on time. But no matter. There was stirring music from longtime Ruane favorites like Willie Alexander, with his hypnotic, beat-infused piano-based songs; Chris Brokaw, with feedback-drenched electric guitar skronk; and Buffalo Tom, with infectious noise-pop. Ruane’s latest find, the young singer Aly Spaltro (also known as Lady Lamb the Beekeeper), delivered a closing segment of wrenching and soulful punk-blues.
Pat McGrath, Ruane’s adviser, emceed at the Middle East and paid tribute to his late friend, warts and all. Southie novelist Michael Patrick MacDonald read a passage based on an encounter with Ruane at a loft party in the ’80s. Though MacDonald’s rough upbringing was far different than Ruane’s life of privilege, they found common ground in punk rock - and liberation through music.
Early on, Randy Black played a tear-jerking version of the Beatles’ “In My Life” and recalled the multiple wet kisses Ruane would plant on him and everyone else. “He connected this community,” Black said. “There was glue in that spit.”
Peter Wolf did three songs, including a mournful “Start All Over Again.” “I’m talking about those good days, those sad days, those happy days,” Wolf sang in the coda. The sometime J. Geils Band singer recalled his first encounter with Ruane after a Geils gig. The dapper, suit-clad Ruane introduced himself before vomiting on Wolf. Nevertheless, a friendship formed, one based on a love of literature, poetry and music.
Ruane’s sister, Lili Ruane, took the stage at the Middle East several times. “You guys are his family,” she said. “You accepted him as he was. He was brilliant, a genius and expressive, as you know.”
The second time she spoke, her boyfriend Win Smith came out to propose as she held the brass urn that contained her brother’s ashes. She accepted. At night’s end, she tossed some of Billy’s ashes into the crowd. (Ultimately, his urn will reside at the Middle East.)
“I understood Billy’s role,” said Jon Langford, a Chicago-based Brit and longtime favorite of Ruane’s whose band Skull Orchard played a ripping set at T.T. the Bear’s. “Billy was a complete maverick, this strange weird thing, totally involved in music.”
Ruane was known for his support, emotional and financial, of numerous musicians. He loved many different kinds of music and that diversity was well represented onstage Wednesday.
“It was a great night,” said singer Linda Viens, who performed with Catherine Coleman. “Billy’s not gone. He lives on in the camaraderie, in the communion, in the great, majestic noise of rock ’n’ roll, and in the hearts of all those destined to love it and to play it.”

Here’s another wide field image of comet 3I/ATLAS. This was imaged on the morning of December 21, 2025. I was only able to get 1 1/2 hours of data before clouds started moving in. Throughout the month it had been clear and mild throughout the US southwest but as luck would have it, storms are finally heading in. This is likely the last time I’ll be able to image this comet. I’ve also posted a short animation showing the comet’s movement over 1 1/2 hours.
