NGC 2276 from Hubble by William Ostling, on Flickr

Full write-up here: https://theastroenthusiast.com/ngc-2276-from-hubble/

The magnificent spiral galaxy NGC 2276 looks a bit lopsided in this Hubble Space Telescope snapshot. A bright hub of older yellowish stars normally lies directly in the center of most spiral galaxies. But the bulge in NGC 2276 looks offset to the upper left. In reality, a neighboring galaxy to the right of NGC 2276 (NGC 2300, not seen here) is gravitationally tugging on its disk of blue stars, pulling the stars on one side of the galaxy outward to distort the galaxy’s normal fried-egg appearance. This sort of “tug of war” between galaxies that pass close enough to feel each other’s gravitational pull is not uncommon in the universe. But, like snowflakes, no two close encounters look exactly alike. In addition, newborn and short-lived massive stars form a bright, blue arm along the upper left edge of NGC 2276. They trace out a lane of intense star formation. This may have been triggered by a prior collision with a dwarf galaxy. It could also be due to NGC 2276 plowing into the superheated gas that lies among galaxies in galaxy clusters. This would compress the gas to precipitate into stars, and trigger a firestorm of starbirth.

By using five color channels spanning near-infrared, visible, and ultraviolet, I was able to reveal not only intense star forming regions (bright nodes of blue) and stars in the dust lanes, but also fainter stellar disruptions (shown on the bottom right).

The Seahorse Nebula (B150) and a bit Flying Bat Nebula (Sh2-129)

It was taken from France (morvan).
With this image I wanted to show that this is the cloud of dust that obscures the starlight. I also wanted a smooth process to stay as close as possible to "reality".

I hope you'll like it.

ImageARP104 by Mathieu Guinot, sur Flickr

Arp 104, also known as Keenan’s System, consists of the two interacting galaxies NGC 5216 (spiral one at bottom) and NGC 5218 (elliptical one at top) which are connected by a thin stream of gas, in which new stars are forming. The stream is about 150,000 light years in length and was created when the two galaxies passed by each other, their mutual gravity pulling the gas out. The newly formed hot and massive stars turn the stream blue.

ARP 104 is located in the constellation Ursa Major at a distance of about 17 million light-years from Earth and there is a large collection of other small and medium galaxies in the field of view. The other prominent one in the top left part of the image is the beautiful spiral NGC 5205.

A spectacular head-on collision between two galaxies - ARP 143 from Hubble by William Ostling, on Flickr

Full write-up here: https://theastroenthusiast.com/a-specta ... om-hubble/

A spectacular head-on collision between two galaxies fueled the unusual triangular-shaped star-birthing frenzy, as captured in a new image from NASA’s Hubble Space Telescope. The interacting galaxy duo is collectively called Arp 143. The pair contains the glittery, distorted, star-forming spiral galaxy NGC 2445 at right, along with its less flashy companion, NGC 2444 at left.

Astronomers suggest that the galaxies passed through each other, igniting the uniquely shaped star-formation firestorm in NGC 2445, where thousands of stars are bursting to life on the right-hand side of the image. This galaxy is awash in starbirth because it is rich in gas, the fuel that makes stars. However, it hasn’t yet escaped the gravitational clutches of its partner NGC 2444, shown on the left side of the image. The pair is waging a cosmic tug-of-war, which NGC 2444 appears to be winning. The galaxy has pulled gas from NGC 2445, forming the oddball triangle of newly minted stars.

While processing, I noticed that the H-alpha data did not fully cover all the background galaxies to the left. The Hubble processors solved this problem by just cropping out that area. I didn’t want to do that, so I just filled the remain h-alpha data with noise and assumed that any h-alpha emission from the background galaxies would be negligible. That way, I could keep all the fascinating background galaxies for you all to look at!

Multicolor Airglow and Zodiacal light over the Atacama Desert

https://www.instagram.com/sergio_vindas/

Description:

Are we able to see the airglow? Yes, it is possible. Sometimes the airglow can be really intense so it can be visible even to the naked eye when we're in the right place with the right conditions. We cannot perceive the colors as the camera sensor, still, it's amazing to “feel” it all over the sky. The most common are green airglow emissions but like in this Image, the chemiluminescence, which is the excitement of Sodium and Oxygen atoms produced by the Sun’s extreme ultraviolet radiation during the daytime, can produce unusual and powerful greenish, reddish and yellowish emissions all at the same time. In Addition, we can observe in the image the Zodiacal Light, Orion, Carina, Magellanic Clouds, and the Milky Way fainted by the intense Airglow and the Zodiacal Light.
The image was captured during an expedition to the Pacana Monks, a large group of huge pillars and rock formations located in a Caldera/Super Volcano relatively close to the Chilean-Argentinian border, a place witness of the fifth larger eruption known until now.

This is an addendum to a submission I made last week. I received some questions asking why Saturn was so dark in the image. The answer is that the difference in brightness between the two objects is very large, and so even with a strong gamma adjustment (uniformly applied), Saturn remains dark relative to the ISS (for an interesting comparison, one can refer to Mars/ISS). I have produced another version of the image, but in this case Saturn has been selectively brightened relative to the rest of the frame. It is still a single frame image, extracted from the video, and the details are in my previous submission. Also, there is an updated time-lapse composite linked below. These are very rare images that show two objects in space that appear similar in size, yet one is very near (and with humans on board!) and one is very far away.

Hi, here are Notculicent clouds with Venus and The Pleides (wide field and with hughe focal length)

Image
Image



Wide field : https://flic.kr/p/2nwecPv
382mm focal length with nice details : https://flic.kr/p/2nwmRYk

This morning, after an astrophotography night with my friend Nicolas Martino, we saw the noctilucent clouds arriving in the north.

We were then able to photograph them with a 6D Canon with a 14mm lens to have them in a wide field.

As the setups were installed, we also captured them with the Takahashi FSQ 106 equipped with the super reducer for a focal length of 382mm.

They were accompanied by Venus and the Pleiades with the beautiful colors of the sun coming into the morning sky.

What a spectacle to see all these atmospheres evolve in the sky and to have the chance to have been able to capture them with a larger focal length.

Hubble's view of the dusty spiral galaxy M66 by William Ostling, on Flickr

Full write-up here: https://theastroenthusiast.com/hubbles- ... alaxy-m66/

The big and beautiful spiral galaxy messier 66 is perhaps one of the most dusty and exciting galaxies to explore. With the recent PHANGS-HST proposal, this galaxy was observed in the ultraviolet, visable, and near-infrared wavelegnths in a way that makes this island universe much easier to understand. First, shining brightly in the infrared are the young star clusters, shown in the image below as blue. Then, in the visible light spectrum, the dust lanes cascading over the stars come into sharp relief. Finally, in the infrared, the light from stars shining in the center of this galaxy glows through.

The distorted spiral shape of Messier 66 most like was caused by gravitational influences with neighboring galaxies. while most spiral galaxies have a nice, even large-scale shape, this particular galaxy looks like it is being laterally stretched.

Kottamia Astronomical Observatory and the milky way Arch
Date : 1st July 2022
Kottamia Observatory  is the largest telescope in the Middle East and North Africa. The telescope, which is located 80 km from the center of old Cairo, has a main mirror diameter of about 1.88 meters (74 inches) and weighs about 2 tons, The diameter of the dome is about 19 meters, and weighs more than 100 tons.

What is the importance of this photo,  The Observatory was established in 1964 and it is  located in the perfect place far from light pollution. But nowadays there is a new  extension of Cairo called the New Governmental Capital located about 13 km form the observatory,  so the north- western horizon of the observatory is fully light polluted and the north-Eastern to south- eastern horizon is at Bortle  scale 3. 
So I think in the upcoming few years the observatory will be at 6-7 Bortle scale at least so it will be difficult to capture the Milky way at the observatory in the next few years . Light pollution is following us and Killing our Observations

Red Spider Nebula. KG Observatory, Julian, CA.

Capturing detail for this interesting object was a challenge due to it's relatively small size. Most of the detail is in the Ha. Fortunately I was able to capture 26 10-min Ha subs between 1.7" and 2.3". Both Ha and OIII were combined, stars removed and RGB stars inserted.

"The Red Spider Nebula (NGC 6537) is a planetary nebula located near the heart of the Milky Way, in the northwest of the constellation Sagittarius. The nebula has a prominent two-lobed shape, possibly due to a binary companion or magnetic fields and has an S-shaped symmetry of the lobes – the lobes opposite each other appear similar. This is believed to be due to the presence of a companion to the central white dwarf. However, the gas walls of the two lobed structures are not at all smooth, but rather are rippled in a complex way.

The central white dwarf, the remaining compact core of the original star, produces a powerful and hot (≈10,000 K) wind blowing with a speed of 300 kilometers per second, which has generated waves 100 billion kilometers high. The waves are generated by supersonic shocks formed when the local gas is compressed and heated in front of the rapidly expanding lobes. Atoms caught in the shocks radiate a visible light. These winds are what give this nebula its unique 'spider' shape and also contribute to the expansion of the nebula.

The star at the center of the Red Spider Nebula is surrounded by a dust shell making its exact properties hard to determine. Its surface temperature is probably 150,000–250,000 K, although a temperature of 340,000 K or even 500,000 K is not ruled out, making it among the hottest white dwarf stars known.

The Red Spider Nebula lies near the constellation of Sagittarius. Its distance has been variously estimated as 1,900 light-year or, more likely, 3,000–8,000 light-years."

Ganymede (JIII) eclipse
Today (July 8) around 1:50 a.m., Jupiter's brightest moon Ganymede (JIII) entered Jupiter's shadow to form a satellite eclipse. During this process, you will see that the four major satellites of Jupiter were originally paired on the left and right sides of Jupiter. At about 1:53, Ganymede, which is close to the right side of Jupiter, began to enter Jupiter's shadow. Although it looks like a small point, it is Ganymede can still be found gradually darkening in the long shot, and Ganymede almost completely disappears from view at 1:55! The video linked below shows Ganymede (JIII) entering Jupiter's shadow to begin the eclipse. We can see Ganymede (JIII) on the right side of Jupiter bright at first, then slowly dimming and then disappearing completely, very interesting. Video link: https://youtu.be/PF4uo9Js4vg.
It wasn't until about 4:58 that Ganymede left Jupiter's shadow to end its three-hour eclipse. At this point, Ganymede appears to appear suddenly to the right of Jupiter, which is very interesting. Unfortunately, because the time of the software simulation was wrong, I didn't record Ganymede's sudden appearance from Jupiter's shadow. At 4:59, the four Galilean satellites around Jupiter all appeared again!
The photos in this group are the six image records of Ganymede's three-hour process from bright to dark, disappearing, and finally reappearing. In the last photo, the sun is about to rise and the sky has turned blue.

Hello,

As promised at the beginning of March, I suddenly made my panorama of Rho Ophiuchus and the Milky Way with sigma art 135mm, I really wanted to image it like that, it's done!

I took it a bit late, in the middle of summer, not much night 3 hours max per night, it is very low on the horizon between 15 10 degrees so not great with light pollution too!

I managed to do 5 nights on it at the end of June to the beginning of July it's always pleasant to shoot at lapn and objective it's all easier

And again collaboration with Philippe Bernhard who made it a marvel

The full is nice to go see

THREE PLANETS AND A MOON WITH EARTHSHINE

I took this photo in Tenerife in Teide National Park in 27th of April 2022. It shows conjunction of 3 planets i.e. Jupiter with its 3 moons ( Io, Europa, Callisto) + Neptun (small but visible) + Venus ( the biggest star ) with a Moon. Additionally I managed to capture the Moon with the Earthshine which is also rare phenomenon visible only couple of days before and after a New Moon, right after sunset or before sunrise. Conjunction is an apparent event that occurs when two or more space objects are visible very close to each other. This photo was done very spontaniously and was completely not planned🔭😀🔭 . This conjuction has attract my attention because was very much visible on the sky. I was in the national park of Teide anyway as I just completed my dark sky photography session so I took out camera one more time and took couple of shots which turned out to be very interesting :) Hope you like this🔭😀☄️ .

Outflows and shockwaves in the the crab nebula – Hubble’s view over the course of 1260 days! by William Ostling, on Flickr

Youtube video here: https://www.youtube.com/watch?v=zypaJw3sD6s

Normally, space is portrayed as static. With objects thousands of light years across, and tens of thousands of parsecs away, what change could we possibly see from earth?

Yet in this video of the crab nebula, we see a dynamic object expanding, rife with shockwaves and speeding outflows. Over the course of 1260 days (3.5 years), we can see the gas in the nebula expand at a blistering pace by about 163,296,000,000 kilometers, or about 0.017 light years. So what’s causing these outflows?

At the center of the Crab Nebula are two faint stars, one of which is the star responsible for the existence of the nebula. It was identified as such in 1942, when Rudolf Minkowski found that its optical spectrum was extremely unusual. The region around the star was found to be a strong source of radio waves in 1949 and X-rays in 1963, and was identified as one of the brightest objects in the sky in gamma rays in 1967. Then, in 1968, the star was found to be emitting its radiation in rapid pulses, becoming one of the first pulsars to be discovered.

Pulsars are sources of powerful electromagnetic radiation, emitted in short and extremely regular pulses many times a second. They were a great mystery when discovered in 1967, and the team who identified the first one considered the possibility that it could be a signal from an advanced civilization. However, the discovery of a pulsating radio source in the center of the Crab Nebula was strong evidence that pulsars were formed by supernova explosions. They now are understood to be rapidly rotating neutron stars, whose powerful magnetic fields concentrates their radiation emissions into narrow beams.

The Crab Pulsar is believed to be about 28–30 km (17–19 mi) in diameter; it emits pulses of radiation every 33 milliseconds. The energy released as the pulsar slows down is enormous, and it powers the emission of the synchrotron radiation of the Crab Nebula, which has a total luminosity about 75,000 times greater than that of the Sun. The pulsar’s extreme energy output creates an unusually dynamic region at the center of the Crab Nebula. While most astronomical objects evolve so slowly that changes are visible only over timescales of many years, the inner parts of the Crab Nebula show changes over timescales of only a few days. The most dynamic feature in the inner part of the nebula is the point where the pulsar’s equatorial wind slams into the bulk of the nebula, forming a shock front. The shape and position of this feature shifts rapidly, with the equatorial wind appearing as a series of wisp-like features that steepen, brighten, then fade as they move away from the pulsar to well out into the main body of the nebula.

MOON IN FALSE COLOR - 46% ILLUMINATED


BEST DETAIL:
https://www.astrobin.com/full/5mtnlu/0/?mod=&real=

The moon is usually seen in subtle shades of gray or yellow.
The different colors are recognized to correspond to actual differences in the chemical composition of the lunar surface. Blue hues reveal areas rich in ilmenite, which contains iron, titanium and oxygen, mainly titanium, while orange and purple show relatively poor titanium and iron regions.
White areas are taller areas that are most exposed to the sun.
Trips to the moon have already been indicated by similar images.

Hello,

As promised at the beginning of March, I suddenly made my panorama of Rho Ophiuchus and the Milky Way with sigma art 135mm, I really wanted to image it like that, it's done!

I took it a bit late, in the middle of summer, not much night 3 hours max per night, it is very low on the horizon between 15 10 degrees so not great with light pollution too!

I managed to do 5 nights on it at the end of June to the beginning of July it's always pleasant to shoot at lapn and objective it's all easier

And again collaboration with Philippe Bernhard who made it a marvel

The full is nice to go see
