Pentas lanceolata, commonly known as Egyptian starcluster, is a species of flowering plant in the family, Rubiaceae that is native to much of Africa . It is known for its wide use as a garden plant where it often accompanies butterfly gardens.
Taken with a Canon rebel t3i (crop sensor) and 135mm rokinon f2 lens. It was challenging trying to fit the subject matter completely in frame, but glad how it turned out.
The night had a haze in the upper atmosphere casting a decently heavy glow on the images. I've never attempted to use data I would usually throw out and I will say, the natural star glow is incredible.
Surprisingly this is only 17 minutes of integration and yet the sharpness and details of the clusters and nebulae are astounding. What a great night.

A new version of the “Christmas tree cluster” is now available. Like NGC 602, NGC 2264 is a cluster of young stars between one and five million years old. (For comparison, the Sun is a middle-aged star about 5 billion years old — about 1,000 times older.) In this image of NGC 2264, which is much closer than NGC 602 at a distance of about 2,500 light-years from Earth, data from NASA's Chandra X-ray Observatory (red, purple, blue, and white) has been combined with optical data (green and violet) captured from by astrophotographer Michael Clow from his telescope in Arizona in November 2024.

The trio of large open clusters ideal for binoculars grouped in Ophiuchus and Serpens — with IC 4756 at left in Serpens, NGC 6633 in Ophiuchus to the right of IC 4756, and IC 4665 at right of frame above the bright star Beta Ophiuchi, or Cebalrai, in Ophiuchus. The pair of NGC 6633 and IC 4756 are also known as the S-O Double Cluster, for their home in Serpens and Ophiuchus. They are an obvious sight when scanning the west side of the summer Milky Way.
Below Cebalrai is the large asterism known as Taurus Poniatowski or the “Little Bull,” a group that resembles the Hyades in Taurus. The group was named for the King of Poland, Stanislaus Poniatowski in 1777 by Marcin Poczobutt. The constellation pattern was never accepted but the asterism, now in Ophiuchus, is a fine one for binoculars.
This is a stack of 9 x 2-minute exposures at f/2.8 with the 85mm Rokinon lens and Canon 6D MkII at ISO 800, plus a single exposure with the Kenko Softon filter blended in to add the star glows.

Background:
Historically, the Pleiades have served as a calendar for many civilizations. The Greek name “Pleiades” probably means “to sail.” In the ancient Mediterranean world, the day that the Pleaides cluster first appeared in the morning sky before sunrise announced the opening of the navigation season.
The modern-day festival of Halloween originates from an old Druid rite that coincided with the midnight culmination of the Pleiades cluster. It was believed that the veil dividing the living from the dead is at its thinnest when the Pleaides culminates – reaches its highest point in the sky – at midnight.
On a lighter note, the Zuni of New Mexico call the Pleiades the “Seed Stars,” because this cluster’s disappearance in the evening sky every spring signals the seed-planting season.
In both myth and science, the Pleiades are considered to be sibling stars. Modern astronomers say the Pleiades stars were born from the same cloud of gas and dust some 100 million years ago. This gravitationally bound cluster of several hundred stars looms some 430 light-years distant, and these sibling stars drift through space together at about 25 miles per second. Many of these Pleiades stars shine hundreds of times more brightly than our sun.

As part of ESA/Hubble’s 35th anniversary celebrations, the European Space Agency (ESA) is sharing a new image series revisiting stunning, previously released Hubble targets with the addition of the latest Hubble data and new processing techniques.
This new image showcases the dazzling young star cluster NGC 346. Although both the James Webb Space Telescope and Hubble have released images of NGC 346 previously, this image includes new data and is the first to combine Hubble observations made at infrared, optical, and ultraviolet wavelengths into an intricately detailed view of this vibrant star-forming factory.
This dazzling NASA/ESA Hubble Space Telescope image features the young star cluster NGC 346.
NGC 346 is in the Small Magellanic Cloud, a satellite galaxy of the Milky Way that lies 200,000 light-years away in the constellation Tucana. The Small Magellanic Cloud is less rich in elements heavier than helium — what astronomers call metals — than the Milky Way. This makes conditions in the galaxy similar to what existed in the early universe.
NGC 346 is home to more than 2,500 newborn stars. The cluster’s most massive stars, which are many times more massive than our Sun, blaze with an intense blue light in this image. The glowing pink nebula and snakelike dark clouds are sculpted by the luminous stars in the cluster.

This is a telephoto lens framing of Comet Tsuchinshan-ATLAS (C/2023 A3) in Ophiuchus on the night of October 30, 2024 near several large star clusters and an asterism. The field of view is 15º by 10º so the tail of the comet seems to extend for about 6º to 8º. Visually, even in binoculars, the tail was much shorter, perhaps only 3º to 4º at best.
The tail extends to the upper left toward a pair of star clusters: At top left is the large loose cluster IC 4756 in Serpens, and to the right of it is NGC 6633 in Ophiuchus. Together they form a nice "double cluster" for binoculars, dubbed the S-O Double Cluster by astronomy author Terence Dickinson.
At lower right above the yellow star Cebalrai in Ophiuchus is the large scattered cluster IC 4665, another fine binocular cluster.
Below the comet is the large V-shaped asterism of stars that resembles the Hyades star cluster in Taurus the Bull. As such it was dubbed "Taurus Poniatovii" (Poniatowski's Bull) by the 18th century Polish astronomer Marcon Paczsobutt in honour of the King of Poland at the time. It was depicted on star charts as a constellation in the early 1800s, but as a formal constellation it is now defunct. However, it is an obvious asterism in binoculars.
At lower left are dark dust clouds in the Milky Way.

In questa immagine a largo campo, ripresa dalla città con il mio solito setup, si svelano due oggetti celesti affascinanti e apparentemente vicini solo per prospettiva: la nebulosa a emissione NGC 7635, nota come "Bubble Nebula", e l’ammasso aperto M52.
La Bubble Nebula è una sfera di gas soffiata dalla potente azione del vento stellare di una giovane stella massiccia, che la illumina dall’interno e ne scolpisce le forme. Il contrasto tra la delicata bolla di idrogeno incandescente e le dense nubi circostanti dona alla nebulosa un aspetto tridimensionale unico.
Poco sopra, l’ammasso aperto Messier 52 raccoglie decine di giovani stelle blu, immerse nel ricco campo stellare della costellazione di Cassiopea. Sebbene visivamente vicini, i due oggetti si trovano a distanze diverse: M52 a circa 5.000 anni luce e la Bubble Nebula a circa 7.100 anni luce dalla Terra.
La foto è stata realizzata sotto un cielo cittadino, con pazienza e passione, sfruttando filtri e tecniche di elaborazione per valorizzare i dettagli e i colori di queste meraviglie celesti nonostante l’inquinamento luminoso. Un piccolo angolo di universo che racconta di stelle nascenti, vento stellare e antichi ammassi nel cuore del nostro braccio di spirale galattico.

Edited Hubble Space Telescope image of the really old globular cluster NGC 6496.
Original caption: This 10.5-billion-year-old globular cluster, NGC 6496, is home to heavy-metal stars of a celestial kind! The stars comprising this spectacular spherical cluster are enriched with much higher proportions of metals — elements heavier than hydrogen and helium, are in astronomy curiously known as metals — than stars found in similar clusters. A handful of these high-metallicity stars are also variable stars, meaning that their brightness fluctuates over time. NGC 6496 hosts a selection of long-period variables — giant pulsating stars whose brightness can take up to, and even over, a thousand days to change — and short-period eclipsing binaries, which dim when eclipsed by a stellar companion. The nature of the variability of these stars can reveal important information about their mass, radius, luminosity, temperature, composition, and evolution, providing astronomers with measurements that would be difficult or even impossible to obtain through other methods. NGC 6496 was discovered in 1826 by Scottish astronomer James Dunlop. The cluster resides at about 35 000 light-years away in the southern constellation of Scorpius (The Scorpion).

Lagoon and Trifid Nebulae mosaic
This is my first attempt at expanding the Lagoon and Trifid mosaic I posted earlier this summer. My setup was not tracking well enough on the west side of the pier at this low altitude to finish it this year; however, barring a supernova, this will look the same again next summer. The nebula hangs at the bottom of the frame due to my desire to extend the picture northward to include the Trifid Nebula and M21. I didn't think it would look good to put an "Under Construction" banner at the top.

This densely populated group of stars is the globular cluster NGC 1841, which is part of the Large Magellanic Cloud (LMC), a satellite galaxy of our Milky Way galaxy that lies about 162,000 light-years away. Satellite galaxies are bound by gravity in orbits around a more massive host galaxy. We typically think of the Andromeda Galaxy as our galaxy’s nearest galactic companion, but it is more accurate to say that Andromeda is the nearest galaxy that is not in orbit around the Milky Way galaxy. In fact, dozens of satellite galaxies orbit our galaxy and they are far closer than Andromeda. The largest and brightest of these is the LMC, which is easily visible to the unaided eye from the southern hemisphere under dark sky conditions away from light pollution.
The LMC is home to many globular clusters. These celestial bodies fall somewhere between open clusters – which are much less dense and tightly bound – and small, compact galaxies. Increasingly sophisticated observations reveal the stellar populations and characteristics of globular clusters are varied and complex, and we have yet to fully understand how these tightly packed groups of stars form. However, there are certain consistencies across all globular clusters: they are very stable and hold their shape for a long time, which means they are generally very old and contain large numbers of very old stars. Globular clusters are akin to celestial ‘fossils.’ Just as fossils provide insight into the early development of life on Earth, globular clusters such as NGC 1841 can provide insights into very early star formation in galaxies.

NASA’s James Webb Space Telescope just solved a conundrum by proving a controversial finding made with the agency’s Hubble Space Telescope more than 20 years ago.
In 2003, Hubble provided evidence of a massive planet around a very old star, almost as old as the universe. Such stars possess only small amounts of heavier elements that are the building blocks of planets. This implied that some planet formation happened when our universe was very young, and those planets had time to form and grow big inside their primordial disks, even bigger than Jupiter. But how? This was puzzling.
To answer this question, researchers used Webb to study stars in a nearby galaxy that, much like the early universe, lacks large amounts of heavy elements. They found that not only do some stars there have planet-forming disks, but that those disks are longer-lived than those seen around young stars in our Milky Way galaxy.
This is a James Webb Space Telescope image of NGC 346, a massive star cluster in the Small Magellanic Cloud, a dwarf galaxy that is one of the Milky Way's nearest neighbors. With its relative lack of elements heavier than hydrogen and helium, the NGC 346 cluster serves as a nearby proxy for studying stellar environments with similar conditions in the early, distant universe. Ten, small, yellow circles overlaid on the image indicate the positions of the ten stars surveyed in this study.
