    The Galactic Plane: Radio Versus Visible

    Explanation:
    What does the Milky Way look like in radio waves? To better find out, GLEAM surveyed the central band of our galaxy in high resolution radio light as imaged by the Murchison Widefield Array in Australia. As the featured video slowly scrolls, radio light (71 - 231 MHz) is seen on the left and visible light -- from the same field -- on the right. Differences are so great because most objects glow differently in radio and visible light, and because visible light is stopped by nearby interstellar dust. These differences are particularly apparent in the direction toward the center of our galaxy, seen about a third of the way through. Among the many features that appear in the radio, bright red patches are usually supernova remnants of exploded stars, while areas colored blue are stellar nurseries filled with bright young stars.

              Explanation:
              What has happened to Comet Lemmon's tail? The answer is blowing in the wind — the wind from the Sun in this case. This continuous outflow of charged particles from the Sun has been quite variable of late, as the Sun emits bursts of energy, CMEs, that push out and deflect charged particles emitted by the comet itself. The result is a blue hued ion tail for Comet C/2025 A6 (Lemmon) that is not only impressively intricate but takes some unusual turns. This long-duration composite image taken from Alfacar, Spain last month captured this inner Solar System ionic tumult. Comet Lemmon is now fading as it heads out away from the Earth and Sun and back into the outer Solar System.

                The Great Crossing
                (Saturn's rings on the edge)

                This movie sequence captures Saturn's rings during a ring plane crossing from the Cassini spacecraft's point of view. The movie begins with a view of the sunlit side of the rings. As the spacecraft speeds from south to north, the rings appear to tilt downward and collapse to a thin plane, and then open again to reveal the un-illuminated side of the ring plane, where sunlight filters through only dimly. The movie consists of 34 images taken over the course of 12 hours as Cassini pierced the ring plane. Six moons careen through the field of view during the sequence. The first large one is Enceladus, whose slanted motion from the upper left to center right nicely illustrates the inclination of its orbit with respect to the rings. The second large one, seen in the second half of the movie, is Mimas, going from right to left.

                Saturn's rings are about 175,000 miles (282,000 km) across, but only about 3,200 feet (~1 km) thick. If you had a model of Saturn that wasCRED a meter stick wide (3 feet), its rings would be about 10,000 times thinner than a razor blade! Saturn and its rings would just fit in the distance between Earth and the Moon.

                Saturn's rings probably formed when objects like comets, asteroids, or even moons broke up in orbit around Saturn due to Saturn's very strong gravity. The pieces of these objects kept colliding with each other and broke into even smaller pieces. These pieces gradually spread around Saturn to form its rings. The rings are thought to be short-lived compared to the age of the Solar System, meaning that if we lived at a very different time, we may not have seen rings around Saturn.

                Saturn's rings are made of billions of pieces of ice, dust and rocks. (more in ALT-text)

This is because Saturn's rings are confined to a plane many times thinner, in proportion, than a razor blade. In modern times, the robotic Cassini spacecraft that orbited Saturn frequently crossed Saturn's ring plane during its mission to Saturn, from 2004 to 2017. A series of plane crossing images from 2005 February was dug out of the vast online Cassini raw image archive by interested Spanish amateur Fernando Garcia Navarro. Pictured here, digitally cropped and set in representative colors, is the striking result. Saturn's thin ring plane appears in blue, bands and clouds in Saturn's upper atmosphere appear in gold. Details of Saturn's rings can be seen in high dark shadows. The moons Dione and Enceladus appear as bumps in the rings.

                          * by Andrea Gianopoulos

                          You can spot Messier 42, better known as the Orion Nebula, with the unaided eye from a dark sky site.

                          Believed to be the cosmic fire of creation by the Maya of Mesoamerica, M42 blazes brightly in the constellation Orion. Popularly called the Orion Nebula, this stellar nursery has been known to many different cultures throughout human history. The nebula is only 1,500 light-years away, making it the closest large star-forming region to Earth and giving it a relatively bright apparent magnitude of 4. Because of its brightness and prominent location just below Orion’s belt, M42 can be spotted with the naked eye, while offering an excellent peek at stellar birth for those with telescopes. It is best observed during January.

                          The Mayan culture’s likening of the Orion Nebula to a cosmic fire of creation is very apt. The nebula is an enormous cloud of dust and gas where vast numbers of new stars are being forged. Its bright, central region is the home of four massive, young stars that shape the nebula. The four hefty stars are called the Trapezium because they are arranged in a trapezoidal pattern. Ultraviolet light unleashed by these stars is carving a cavity in the nebula and disrupting the growth of hundreds of smaller stars.

                          This stunning Hubble image offers the sharpest view of the Orion Nebula ever obtained. Created using 520 different Hubble exposures taken in multiple wavelengths of light, this mosaic contains over one billion pixels. Hubble imaged most of the nebula, but ground-based images were used to fill in the gaps in its observations. The orange color in the image can be attributed to hydrogen, green represents oxygen, and the red represents both sulfur and observations made in infrared light.

                          Resembling an interstellar Frisbee, the dark feature in these two Hubble images is a protoplanetary disk of dust seen edge-on around a newborn star in M42. The two images show the disk through two different sets of filters: one to probe the disk’s chemical composition (left) and another to reduce the brightness of the nebula, revealing brighter regions above and below the disk that betray the presence of the star (right). Because the disk is edge-on, its star is largely hidden, but the disk may be an embryonic planetary system in the making. Our solar system probably formed out of such a disk 4.5 billion years ago.

                            Hubble Spies Brown Dwarfs in Nearby Stellar Nursery

                            [...]
                            Appearing like glistening precious stones surrounding a setting of sparkling diamonds, more than 300 fledgling stars and brown dwarfs surround the brightest, most massive stars [center of picture] in Hubble's view of the Trapezium cluster's central region. All of the celestial objects in the Trapezium were born together in this hotbed of star formation. The cluster is named for the trapezoidal alignment of those central massive stars.

                            Brown dwarfs are gaseous objects with masses so low their cores never become hot enough to fuse hydrogen, the thermonuclear fuel stars like the Sun need to shine steadily. Instead, these gaseous objects fade and cool as they grow older. [...]

                            This finding, along with observations from ground-based telescopes, is further evidence that brown dwarfs, once considered exotic objects, are nearly as abundant as stars. The image and results appear in the Sept. 20 issue of the Astrophysical Journal.

                            The brown dwarfs are too dim to be seen in a visible-light image taken by the Hubble telescope's Wide Field and Planetary Camera 2 [picture at left]. This view also doesn't show the assemblage of infant stars seen in the near-infrared image. That's because the young stars are embedded in dense clouds of dust and gas. The Hubble telescope's near-infrared camera, the Near Infrared Camera and Multi-Object Spectrometer, penetrated those clouds to capture a view of those objects. The brown dwarfs are the faintest objects in the image. Surveying the cluster's central region, the Hubble telescope spied brown dwarfs with masses equaling 10 to 80 Jupiters. Researchers think there may be less massive brown dwarfs that are beyond the limits of Hubble's vision.

                              Orion Nebula proplyd atlas

                              This atlas features 30 proplyds, or protoplanetary discs, that were recently discovered in the majestic Orion Nebula. Using the wide field channel on Hubble’s Advanced Camera for Surveys (ACS), astronomers discovered a total of 42 new discs that could be the seeds of planetary systems to come. Within the awe-inspiring, gaseous folds of Orion, researchers have identified two different types of discs around young and forming stars: those that lie close to the brightest star in the cluster (Theta 1 Orionis C) and those farther away from it. The bright star heats up the gas in the nearby discs, causing them to shine brightly. The discs that are farther away do not receive enough of the energetic radiation from the star to set the gas ablaze; thus, they can only be detected as dark silhouettes against the background of the bright nebula, as the dust that surrounds these discs absorbs background visible light. By studying these silhouetted discs, astronomers are better able to characterize the properties of the dust grains that are thought to bind together and possibly form planets like our own. In the brighter discs the excited material produces many glowing cusps, which all face the bright star, but from our point of view are randomly oriented through the nebula, so we see some edge on, and others face on, for instance. Other interesting features enhance the look of these captivating objects, such as emerging jets of matter and shock waves. The dramatic shock waves are formed when the stellar wind from the nearby massive star collides with the gas in the nebula, sculpting boomerang shapes or arrows or even, in the case of 181-825, a space jellyfish!

                                This magnificent extragalactic skyscape looks toward the Andromeda Galaxy, the closest large spiral galaxy to the Milky Way. It also accomplishes a Messier catalog trifecta by including Andromeda, cataloged as Messier 31 (M31), along with Messier 32 (M32), and Messier 110 (M110) in the same telescopic field of view. In this frame, M32 is just left of the Andromeda Galaxy's bright core with M110 below and to the right. M32 and M110 are both elliptical galaxies themselves and satellites of the larger spiral Andromeda. By combining 60 hours of broadband and narrowband image data, the deep telescopic view also reveals tantalizing details of dust lanes, young star clusters, and star-forming regions along Andromeda's spiral arms, and faint, foreground clouds of glowing hydrogen gas. For now, Andromeda and friends are some 2.5 million light-years from our own large spiral Milky Way.

The stunning sequence (left to right) of three all-sky exposures, taken at 30 second intervals, shows rapid changes in dancing curtains of northern lights against a starry background. What makes the northern lights dance? Measurements by NASA's fleet of THEMIS spacecraft indicate that these explosions of auroral activity are driven by sudden releases of energy in the Earth's magnetosphere called magnetic reconnection events. The reconnection events release energy when magnetic field lines snap like rubber bands, driving charged particles into the upper atmosphere. Stretching into space, these reconnection events occur in the magnetosphere on the Earth's night side at a distance about 1/3 of the way to the Moon.

                                            Just back from vacation. I saw some colorful frogs at a store and they inspired me to create a painting! I had so much fun! I am keeping the original. Prints below!

                                              Orion and the Running Man

                                              Explanation:
                                              Few cosmic vistas can excite the imagination like The Great Nebula in Orion. Visible as a faint, bland celestial smudge to the naked-eye, the nearest large star-forming region sprawls across this sharp colorful telescopic image. Designated M42 in the Messier Catalog, the Orion Nebula's glowing gas and dust surrounds hot, young stars. About 40 light-years across, M42 is at the edge of an immense interstellar molecular cloud only 1,500 light-years away that lies within the same spiral arm of our Milky Way galaxy as the Sun. Including dusty bluish reflection nebula NGC 1977, also known as the Running Man nebula at left in the frame, the natal nebulae represent only a small fraction of our galactic neighborhood's wealth of star-forming material. Within the well-studied stellar nursery, astronomers have also identified what appear to be numerous infant solar systems.

                                                We got to see these mysterious creatures up close and personal. Watching them move seemed to calm my vagus nerve. Peaceful....They are mostly in the rivers, but sometimes they show up at the beach!

The effect is created by the diffraction of light around individual, similarly-sized water droplets in an intervening but mostly transparent cloud. Since light of different colors has different wavelengths, each color diffracts differently. Lunar coronae are one of the few color diffraction effects that can be easily seen with the unaided eye. The featured image of a lunar corona was captured around last week's full Super Moon from near Knight's Ferry, California, USA. To the right of the full Moon is the giant orange star Botein. Similar coronae that form around the Sun are typically harder to see because of the Sun's great brightness.

To better interpret Jupiter's cloud motions and to help NASA's robotic Juno spacecraft understand the planetary context of the small fields that it sees, the Hubble Space Telescope was being directed to regularly image the entire Jovian giant. The colors of Jupiter being monitored go beyond the normal human visual range to include both ultraviolet and (not pictured) infrared light. Featured from 2017, Jupiter appears different in near ultraviolet light, partly because the amount of sunlight reflected back is distinct, giving differing cloud heights and latitudes discrepant brightnesses. In the near UV, Jupiter's poles appear relatively dark, as does its Great Red Spot and a smaller (optically) white oval to the right. The String of Pearl storms farther to the right, however, are brightest in near ultraviolet, and so here appear (false-color) pink. Jupiter's largest moon Ganymede appears on the upper left. Juno continues on a looping 33-day orbit around Jupiter, while Earth-orbiting Hubble is aging and now relies on a single stabilizing gyroscope.

                                                                    Though once big enough to swallow three Earths with room to spare, Jupiter’s Great Red Spot has been shrinking for a century and a half. Nobody is sure how long the storm will continue to contract or whether it will disappear altogether.

                                                                    A new study suggests that it hasn’t all been downhill, though. The storm seems to have increased in area at least once along the way, and it’s growing taller as it gets smaller.

                                                                    “Storms are dynamic, and that’s what we see with the Great Red Spot. It’s constantly changing in size and shape, and its winds shift, as well,” said Amy Simon, an expert in planetary atmospheres at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and lead author of the new paper, published in the Astronomical Journal.

                                                                    Observations of Jupiter date back centuries, but the first confirmed sighting of the Great Red Spot was in 1831. (Researchers aren’t certain whether earlier observers who saw a red spot on Jupiter were looking at the same storm.)

                                                                    Keen observers have long been able to measure the size and drift of the Great Red Spot by fitting their telescopes with an eyepiece scored with crosshairs. A continuous record of at least one observation of this kind per year dates back to 1878.

                                                                    Simon and her colleagues drew on this rich archive of historical observations and combined them with data from NASA spacecraft, starting with the two Voyager missions in 1979. In particular, the group relied on a series of annual observations of Jupiter that team members have been conducting with NASA’s Hubble Space Telescope as part of the Outer Planets Atmospheres Legacy, or OPAL, project. The OPAL team scientists are based at Goddard, the University of California at Berkeley, and NASA’s Jet Propulsion Laboratory in Pasadena, California. ...

                                                                        Juno's recent orbits have provided exceptionally clear views of Jupiter's circumpolar cyclones. At closest approach in this series of images, the Juno spacecraft was about 6,800 miles (11,000 kilometers) above the cloud tops, at a latitude of 82 degrees north of the equator.

These differing perspectives allowed Juno scientists to deduce that all Jovian polar cyclones are not created equal.

                                                                            The infrared image, on the far right, was derived from data collected by the spacecraft's Jovian Infrared Auroral Mapper (JIRAM) instrument. The composite image at center was collected by the JunoCam visible-light imager. Though taken with separate instruments that record different wavelengths of light, both images depict Jupiter's northern polar storms as well defined and of similar size.

                                                                            The data on the left, collected by Juno's Microwave Radiometer (MWR), shows the polar storms in another light. MWR enables Juno to see deep into Jupiter by recording the planet's microwave emissions. In the MWR graphic, the polar storms at the 4 and 6 o'clock positions have bright microwave signatures, indicating they extend well beneath the cloud tops, at least 62 miles (100 kilometers) below. The size of those two storms is comparable to what's found in the visible light and infrared light images, but the other storms, as seen through MWR, have a notably reduced emissions intensity.

                                                                            Another disparity in the MWR graphic versus visible light and infrared can be seen in how the central cyclone is depicted by the data. ...

In the infrared and visible light images, the central cyclone is evident; with MWR data, it all but disappears. This disparity indicates that the central cyclone's subsurface structure must be very different from the surrounding storms. JIRAM "sees" in infrared light not visible to the human eye. It captures the infrared glow from the heat of Jupiter's upper atmosphere, probing the top of the weather layer, and gaps in the clouds allow glimpses as deep as 30 to 45 miles (50 to 70 kilometers) below Jupiter's cloud tops. JunoCam's visible light images catch reflected sunlight, with a view that is very similar to what a human eye would see if a person could ride along with Juno. JunoCam's raw images are available for the public to peruse and process into image products at https://missionjuno.swri.edu/junocam/processing. Like JIRAM, the MWR instrument records the glow of Jupiter's atmosphere, but the brightness results from the temperature at depths below anything achievable with previous spacecraft or Earth-based observations. The MWR's six radio channels peer progressively deeper below the visible cloud tops, with a range from the top of the clouds (for the highest frequency channel) to 200 miles (320 kilometers) or more below (for the lowest frequency channel).

They provide a good look at Jupiter’s colorful belts and swirling storms, including the Great Red Spot. Close examination reveals something more: two glimpses of the tiny moon Amalthea (see Figure B below).

In 2000, NASA’s Galileo spacecraft revealed some surface features, including impact craters, hills, and valleys. Amalthea circles Jupiter inside Io's orbit, which is the innermost of the planet’s four largest moons, taking 0.498 Earth days to complete one orbit.

                                                                              Amalthea is the reddest object in the solar system, and observations indicate it gives out more heat than it receives from the Sun. This may be because, as it orbits within Jupiter's powerful magnetic field, electric currents are induced in the moon's core. Alternatively, the heat could be from tidal stresses caused by Jupiter’s gravity.

                                                                              At the time that the first of these two images was taken, the Juno spacecraft was about 165,000 miles (265,000 kilometers) above Jupiter’s cloud tops, at a latitude of about 5 degrees north of the equator.
