IC 1805 is a nebula located 7,500 light-years away in the constellation Cassiopeia. Its reddish appearance comes from gases ionized by the massive young stars of the Melotte 15 cluster. It is a region where many stars are still forming today.
IC 1848, the Soul Nebula, is located 7,500 light-years away in the constellation Cassiopeia. It is illuminated by young stars that ionize the surrounding gases, giving it its reddish hue. The nebula features structures known as "pillars of creation," where new stars are formed from clouds of gas and dust.

It is one of the images ( The Witch Head Nebula) that has brought me the most satisfaction, as photographing reflection nebulae from a city seemed like an impossible idea, despite the light pollution filters available today. This session was taken from a fifth-floor balcony in my city, Montcada i Reixac, near Barcelona (Catalonia), in a Bortle 8/9 zone with no visibility to the North, without Polaris, using drift alignment. I needed several sessions and many captures, but I couldn’t be happier with the result. It still feels unbelievable to me.

Thinking about what we are gradually losing in cities, and realizing that it shouldn't be a privilege but a right and a heritage not only of humanity but of all the inhabitants of our planet—fauna and flora—and seeing that, despite everything, it is still possible

This 2-panel mosaic shows both the Heart Nebula (IC 1805) at the bottom and the Soul Nebula (IC 1848) at the top. These emission nebulae, located in the Perseus Arm of the Milky Way, are roughly 7,500 light-years away in the constellation Cassiopeia.
Heart and Soul of the Cosmos!
Heart and Soul of the Cosmos!
Astrobin: https://www.astrobin.com/lyttra/

Here's a breakdown of the scientific highlights:

Heart Nebula (IC 1805)
Type: Emission Nebula
Notable Feature: Dominated by glowing hydrogen gas and dark dust lanes sculpted by stellar winds.
Star Cluster: Melotte 15, located near the center, contains young, massive stars responsible for energizing the surrounding gas.

Soul Nebula (IC 1848)
Type: Emission Nebula
Structure: Composed of numerous small star-forming regions and pillars of gas and dust.

Both nebulae are active star-forming regions, with intense radiation from young stars carving intricate structures in the surrounding gas and dust. These are classic examples of how stellar nurseries shape their environments. I’m thrilled with how this mosaic came together and how the delicate structures stand out in the final image.

This image has a combined exposure of 50+ hours with a ZWO 294mm Pro camera and a William optics Redcat 51.

Title: Ripples and loops of stars and cold gas shine light on the giant radio lobes of NGC 1316

Image Credit & Copyright: Filippo Maccagni, Paolo Serra, Ferrante Enriques; INAF, SARAO.

Image

NGC 1316 (aka Fornax A) is one of the brightest galaxies in the Fornax constellation. Astronomers think that it formed 1-2 billion years ago, when a galaxy similar to our own Milky Way smashed into a ten times larger galaxy. After this collision, NGC 1316 continued swallowing smaller satellite galaxies attracted by its strong gravitational pull. These turbulent events left behind numerous ripples and loops made of tens of millions of stars each, visible in the background optical image. Astronomers discovered that the same collisions enriched the space around NGC 1316 with cold gas (shown in blue and visible with radio telescopes) lost by individual galaxies. Some of this gas fell into the 100-million-solar-masses black hole located at the centre of NGC 1316, triggering the ejection of streams of electrons which travel close to the speed of light. These electrons formed giant (1 million light years across) balloon-shaped lobes, shown in red and also visible with radio telescopes. Astronomers discovered that the radio lobes are inflated intermittently with fresh electrons as a result of the occasional feeding of the central black hole with cold gas. The interval between these “meals” is of the order of some million years. One such meal is being consumed right now, as astronomers find traces of the ongoing ejection of fast electrons in the very centre of NGC 1316.

This image is a composite of an optical image (in the background) and two radio images (blue for the cold gas, and red for the radiation emitted by the relativistic electrons). The optical image is a 63-h LRGB exposure taken in October 2024 with a 14-cm CFF refractor located in Hakos Astrofarm, Namibia. The radio images were obtained with a 15 h-long observation at a frequency of 1.4 GHz with the MeerKAT interferometric radio telescope located in the Karoo Desert, South Africa.

PK 164+31.1, also known as Jones-Emberson 1, is a planetary nebula in the constellation Lynx. Its intricate structure and relatively faint luminosity make it a challenging target for astrophotographers. However, with patience and dedication, this “hidden gem” can be transformed into a stunning window into the deep sky.

ImageJones-Embseron 1 by Alessandro Ravagnin, su Flickr

The nebula appears as a faint, diffuse spherical shell with an irregular structure. Its most striking features include internal rings and filaments, likely formed due to instabilities in the mass-loss process of the progenitor star. Hα and OIII filters reveal distinct details: OIII highlights the hotter, ionized regions, while Hα traces the denser gas.

The characteristic blue-green color, visible in broadband images, primarily results from the emission of doubly ionized oxygen (OIII), while the reddish tones are due to ionized hydrogen (Hα).

This nebula is the remnant of the outer layers expelled by a Sun-like star in its final life stages. The central star, visible as a small, hot white dwarf, is the remaining core of the progenitor star. Its temperature exceeds 100,000 K, making it hot enough to ionize the surrounding gas.

As a planetary nebula in its advanced stage, the gas shell is gradually expanding and dispersing into the interstellar medium. PK 164+31.1 is thought to be a bipolar nebula, seen almost perfectly along the axis of its two lobes, with an estimated age of 15,000 years. At this stage, the ejected material begins to blend into the surrounding interstellar environment.

What is it?
Here attached my NGC281 (“Pacman” Nebula) in Cassiopea. It’s my second picture and attempt to win the APOD. What I like most is the star forming area with its Bok globules so visible in the picture! Open cluster IC1590 in the middle and the multiple star B1 enrich further more this wonderful 1/2 degree sky area. 9500 ly from us and aroun 40ly size. The reason why is also known as the Pacman Nebula looks very clear to middle age man like me but we should may be explain better to young generations!

Image production technique
The picture is the result of a classic Hubble Palette for the Nebula (Luminance + Color) and an RGB combination for the Stars. An HDR has been applied on the Nebula to show better all details hidden by excessive light in the center. All this work has been assessed through Pixinsight and Photoshop software. I also used 3 RC Astro Tools for noise reduction, stars separation and improve definition.

An amateur discovery of a small bipolar nebula in the Cygnus

we are proud to present you with an amateur discovery. The discovery dates back to November 2023, a small bipolar nebula in the Cygnus. Today we know that it is a Herbig-Haro object (HHO).

Image

There is also an RNAAS paper about it. https://iopscience.iop.org/article/10.3 ... 172/ad103a
Peter Bresseler (me) is an amateur, Bringfried Stecklum is an astronom.

The attached image is a co-production of the amateur discoverer Peter Bresseler and the astrophotographers Bernd Koch and Werner E. Celnik. The bipolar nebula was photographed with a Celestron C14 at F/7 with an ASI2600MC in LRGB mode and exposed for 21.8 hours. The coordinates are 20:53:25.3 +51:08:17.7. We hope that more amateurs will participate in the exposures.

thanks for looking

Herbig-Haro objects are small bright patches of nebulosity associated with protostars. They are formed when hot gas ejected by a newborn star collides with the gas and dust around it at creating bright shock waves.

Some believe that rogue planets may also be formed in this way…. The dark dust of the Perseus molecular cloud hides much of the star-forming activity. However the infrared camera on the James Webb Space Telescope can peak through the dust. Recent images from JWST of NGC 1333 have identified 6 Rogue planets forming. Go google the image its’ awesome
