NASA, ESA, CSA, STScI High-resolution near-infrared light captured by NASA’s James Webb Space Telescope shows extraordinary new detail and structure in Lynds 483 (L483). Two actively forming stars are responsible for the shimmering ejections of gas and dust that gleam in orange, blue, and purple in this representative color image.
Over tens of thousands of years, the central protostars have periodically ejected some of the gas and dust, spewing it out as tight, fast jets and slightly slower outflows that “trip” across space. When more recent ejections hit older ones, the material can crumple and twirl based on the densities of what is colliding. Over time, chemical reactions within these ejections and the surrounding cloud have produced a range of molecules, like carbon monoxide, methanol, and several other organic compounds.

The two protostars responsible for this scene are at the center of the hourglass shape, in an opaque horizontal disk of cold gas and dust that fits within a single pixel. Much farther out, above and below the flattened disk where dust is thinner, the bright light from the stars shines through the gas and dust, forming large semi-transparent orange cones.
It’s equally important to notice where the stars’ light is blocked — look for the exceptionally dark, wide V-shapes offset by 90 degrees from the orange cones. These areas may look like there is no material, but it’s actually where the surrounding dust is the densest, and little starlight penetrates it. If you look carefully at these areas, Webb’s sensitive NIRCam (Near-Infrared Camera) has picked up distant stars as muted orange pinpoints behind this dust. Where the view is free of obscuring dust, stars shine brightly in white and blue.
Unraveling the Stars’ Ejections
Some of the stars’ jets and outflows have wound up twisted or warped. To find examples, look toward the top right edge where there’s a prominent orange arc. This is a shock front, where the stars’ ejections were slowed by existing, denser material.
Now, look a little lower, where orange meets pink. Here, material looks like a tangled mess. These are new, incredibly fine details Webb has revealed, and will require detailed study to explain.
Turn to the lower half. Here, the gas and dust appear thicker. Zoom in to find tiny light purple pillars. They point toward the central stars’ nonstop winds, and formed because the material within them is dense enough that it hasn’t yet been blown away. L483 is too large to fit in a single Webb snapshot, and this image was taken to fully capture the upper section and outflows, which is why the lower section is only partially shown. (See a larger view observed by NASA’s retired Spitzer Space Telescope.)
All the symmetries and asymmetries in these clouds may eventually be explained as researchers reconstruct the history of the stars’ ejections, in part by updating models to produce the same effects. Astronomers will also eventually calculate how much material the stars have expelled, which molecules were created when material smashed together, and how dense each area is.
Millions of years from now, when the stars are finished forming, they may each be about the mass of our Sun. Their outflows will have cleared the area — sweeping away these semi-transparent ejections. All that may remain is a tiny disk of gas and dust where planets may eventually form.
L483 is named for American astronomer Beverly T. Lynds, who published extensive catalogs of “dark” and “bright” nebulae in the early 1960s. She did this by carefully examining photographic plates (which preceded film) of the first Palomar Observatory Sky Survey, accurately recording each object’s coordinates and characteristics. These catalogs provided astronomers with detailed maps of dense dust clouds where stars form — critical resources for the astronomical community decades before the first digital files became available and access to the internet was widespread.
The James Webb Space Telescope is the world’s premier space science observatory. Webb will solve mysteries in our solar system, look beyond to distant worlds around other stars, and probe the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and the Canadian Space Agency.

Throughout the years, reports of alien abductions have emerged from all corners of the globe.
An alien abduction is generally described as an event in which individuals report being taken against their will by extraterrestrial beings, often undergoing various forms of physical and psychological experimentation.
Some argue that these experiences could simply reflect the subconscious mind at work or suggest that the abductees may have unknowingly been subjects of classified military experiments. Nonetheless, many abductees share accounts with such remarkable detail and consistency that some researchers feel the phenomenon deserves serious consideration.
Over time, I’ve shared numerous articles on cases of alleged alien abductions, which you can explore under the "alien abduction" tag below the article.
Here are two more intriguing cases in which abductees recount their experiences in vivid detail, prompting us to seriously consider the possibility that people may actually be taken by aliens.
The Betty Andreasson Alien Abduction: A Strange Encounter in 1967
One of the most detailed and haunting accounts of alien abduction began on January 25, 1967, in South Ashburnham, Massachusetts. That evening, Betty Andreasson’s family experienced a power outage, followed by an eerie red light outside. Peering out, Betty’s father saw five strange beings approaching who soon entered the house, seemingly passing through solid walls. They communicated telepathically and temporarily froze the family in place.
These beings had distinctive appearances, with pear-shaped heads, wide eyes, and a calm, almost friendly aura. Betty was led to a spacecraft in her backyard and taken aboard, where she underwent strange tests and experienced an otherworldly vision. Hours later, she was returned home, and the aliens left her family unharmed. Initially, Betty viewed her experience through a religious lens, but over time, she came to see it as an alien encounter.
Years later, her story caught the attention of Dr. J. Allen Hynek, a leading UFO researcher. Under hypnosis, Betty’s fragmented memories resurfaced, revealing consistent details corroborated by her daughter, who had also been briefly unfrozen by the beings. After extensive testing and interviews, investigators concluded that Betty was credible and sincerely believed in what she described. The Betty Andreasson abduction remains one of the most compelling cases in UFO lore.
The 1974 Medicine Bow National Forest Abduction: Carl Higdon's Astonishing Encounter
Carl Higdon's hunting trip to Wyoming’s Medicine Bow National Forest in October 1974 took a surreal turn when he experienced one of the most bizarre UFO abduction cases on record. Aiming at an elk, Higdon was stunned to see his bullet slow mid-air and drop, seemingly defying physics. Moments later, he noticed an unusual figure—a tall being in a black jumpsuit with rod-like appendages instead of hands—who offered him pills, claiming that one would sustain him for days.
Higdon, inexplicably compliant, swallowed a pill and suddenly found himself in a transparent structure with two more beings and five frozen elk. He was told they were traveling 163,000 light-years away to the aliens' home planet, which he described as filled with towering structures and an intensely bright sun.
Two and a half hours later, Higdon was back in Medicine Bow, disoriented and missing his elk. Later medical tests revealed inexplicably high vitamin levels and the disappearance of old lung scars. Adding credibility to his story, other witnesses reported seeing strange lights in the area. Higdon’s experience remains a mysterious case.

Launched in May, ESA’s EarthCARE satellite has been making waves, with the first images from three of its scientific instruments already delivered. Now, the spotlight is firmly on the atmospheric lidar, the most advanced of the satellite’s four instruments.
This cutting-edge sensor has captured detailed 20 km-high vertical profiles of atmospheric aerosols – tiny particles and droplets from natural sources like wildfires, dust, and sea spray, and from human activities like industrial emissions or burning of wood – and clouds across various regions of the globe.
