Messier 14 – Metal-Poor Globular Cluster in Ophiuchus Messier 14 (NGC 6402) is a moderately concentrated globular cluster located in the constellation Ophiuchus, approximately 30,300 light-years from Earth. With an estimated age of ~13.25 billion years, it is a representative example of the old, metal-poor stellar populations that inhabit the Galactic halo. The cluster spans about 100 light-years in diameter and contains several hundred thousand Population II stars. Its low metallicity ([Fe/H] ≈ –1.28) reflects a formation epoch early in the history of the Milky Way. M14 is classified as a Shapley-Sawyer Class VIII cluster and exhibits a relatively diffuse outer halo surrounding a dense core. More than 70 RR Lyrae variable stars have been identified within the cluster, making it useful for refining distance measurements through the period-luminosity relation. In 1938, a nova event was recorded on photographic plates, one of the few confirmed nova eruptions within a globular cluster. Imaging Details: Telescope: Celestron EdgeHD 8" Camera: ZWO ASI1600MM Pro Filters: ZWO Red, Green, Blue (36mm) Exposure: Red: 96 × 60 sec Green: 90 × 60 sec Blue: 90 × 60 sec Mount: Sky-Watcher EQ6-R Pro Software: NINA (acquisition), PixInsight (processing) This image resolves the core and extended halo of M14 in broadband RGB. The cluster’s structure and variable population contribute to studies of globular cluster dynamics, distance calibration, and the early chemical evolution of the Milky Way.

NGC 6752 – Globular Cluster in Pavo One of the brightest and nearest globular clusters in our galaxy, NGC 6752 lies roughly 13,000 light-years away in the constellation Pavo. This dense sphere of ancient stars is estimated to be over 11 billion years old and contains multiple stellar populations, including blue stragglers and millisecond pulsars—signposts of complex internal dynamics and stellar evolution. Captured using RGB filters, this image reveals the dense core and surrounding halo of stars, tightly packed into a cluster only ~100 light-years across. NGC 6752 is a post-core-collapse cluster, and its high central concentration is evident even at modest image scale.

This is NGC6752, one of the brightest and nearest globular clusters to us at 13,000ly away. Working on RCW58 that sets at 11:30pm local, so I hopped over to this nice cluster for the second half of the night and got about 4.5 hours on it. #astrophotography

Did our local supermassive black hole recently eat its little sibling? Indirect evidence suggests a smaller black hole orbited the much, much larger one

So, did our local supermassive monster black hole eat a slightly smaller but still quite huge black hole some time in the cosmically recent past?

Actually, yeah, maybe!

looking out over a natural flat rock shell towards a small hill. There are some clouds that are being silouetted against the bright red and green aurora

If you remember, there was loads of places around the world - even at higher latitudes (reported as high as Sydney) that saw the night sky dazzle in reds, green, soft purples and pinks.

That's our magnetosphere protecting us from the jerk Sun.

This release features two composite images of a long, thin, cosmic structure. With the structure's vertical orientation, seemingly fragile dimensions, and pale grey color against the blackness of space, the images resemble medical X-rays of a long, thin, bone. The main image shows the structure in its entirety. The inset image is an annotated close-up highlighting an apparent fracture in the bone-like structure. The structure, called G359.13, or "The Snake", is a Galactic Center Filament. These filament formations are threaded by parallel magnetic fields, and spiraling, energized particles. The particles cause radio waves, which can be detected by radio arrays, in this case by the MeerKAT array in South Africa. In the first composite image, the largely straight filament stretches from the top to the bottom of the vertical frame. At each end of the grey filament is a hazy grey cloud. The only color in the image is neon blue, found in a few specks which dot the blackness surrounding the structure. The blue represents X-rays seen by NASA's Chandra X-ray Observatory. In the annotated close-up, one such speck appears to be interacting with the structure itself. This is a fast-moving, rapidly spinning neutron star, otherwise known as a pulsar. Astronomers believe that this pulsar has struck the filament halfway down its length, distorting the magnetic field and radio signal. In both images, this distortion resembles a small break, or spur, in the bone-like filament.

Something punched a celestial snake in the gut.

Radio images show the center of our galaxy is full of long, puzzling magnetic "snakes." This one has an unusual kink in it--apparently from where it was smacked by a pulsar racing by at nearly 1000 km/sec. 🧪🔭
