12 by 12 - Challenge #4
Take what you believe will be the final series of photographs before you die. — Nick Brandt
thinking about this challenge brought back so many memories of already dead family members and i dived deep down into our family slides…
i believe that death is not the end, so i started to think about my last series would become a series at a place between life and death.
maybe there is a spot somewhere in the universe, where i’ll meet my family and friends. and from there we will start to explore the whole universe together…
thanks for this challenge

The Crab Nebula AKA, M1 (Messier 1), NGC 1952, Taurus A is a supernova remnant and pulsar wind nebula in the constellation of Taurus.. It is about 6,500 light-years from earth and contains a pulsar neutron star, which would explain the brightness of the cloud. I took this image using narrowband filters over many nights for more than 11 hours of exposure time.

I have wanted to get a detailed shot of this supernova remnant for quite some time. The guiding wasn't perfect this night, but I'm pleased with the overall result. I wonder if I'll be able to do this well enough again in the future to watch the expansion of the nebula that continues from when it appeared in the sky as a supernova in 1054 C.E.

The Crab Nebula is a supernova remnant in the constellation of Taurus. Corresponding to a bright supernova recorded by Chinese astronomers in 1054, the nebula was observed later by English astronomer John Bevis in 1731. The nebula was the first astronomical object identified with a historical supernova explosion.
The nebula lies in the Perseus Arm of the Milky Way, at a distance of about 6,500 light-years from Earth. It has a diameter of 11 light-years, corresponding to an apparent diameter of some 7 arcminutes, and is expanding at a rate of about 1,500 km/sec.
At the center of the nebula lies the Crab Pulsar, a neutron star 28–30 km across with a spin rate of 30.2 times per second, which emits pulses of radiation from gamma rays to radio waves. At X-ray and gamma ray energies above 30 keV, the Crab Nebula is generally the brightest persistent source in the sky
This image of the Crab Nebula combines data from NASA’s Imaging X-ray Polarimetry Explorer (IXPE) in magenta and NASA’s Chandra X-ray Observatory in dark purple.
IXPE data show that the Crab Nebula’s magnetic field resembles that of the Vela Pulsar Wind Nebula, which is also donut-shaped. But at the Crab, scientists were surprised that areas of magnetic field turbulence were more patchy and asymmetrical than expected.

When astronomers use the NASA/ESA Hubble Space Telescope to study the deep sky, asteroids from our Solar System can leave their marks on the captured pictures of far-away galaxies or nebulae. But rather than be annoyed at the imprinted trails in Hubble images, astronomers realised they could use them to find out more about the asteroids themselves.
To do this, a team of ESA astronomers and software engineers started the Hubble Asteroid Hunter citizen science project in June, enlisting the public to help them find asteroids observed by chance in Hubble archival images. Through this project, over 1900 volunteers have identified more than 300 000 asteroid trails in nearly 11 000 images in only 1.5 months, completing the project with swiftness and enthusiasm that exceeded the team’s expectations.
Astronomy-enthusiast Melina Thévenot from Germany was one of the project’s keen volunteers. While analysing Hubble data, she found an asteroid trail on the foreground of a 2005 image of the Crab Nebula, one of the night sky's most famous objects.
Inspired by this impressive combination, Melina decided to process the original Hubble image combining views taken in blue, green and red filters, to create the stunning colour scene portrayed here. The faint trail of 2001 SE101, a main-belt asteroid discovered by the ground-based LINEAR survey in 2001, appears as a curved streak that crosses the image from bottom left to top right, near the nebula’s centre.
The Crab Nebula, also known as Messier 1 or M1, was the first object recorded by French astronomer Charles Messier in his famous catalogue of deep-sky objects. It is the expanding remnant of a bright supernova explosion observed by astronomers in 1054. Aside from the swirling cloud of gas and dust, the explosion left behind a rapidly rotating neutron star at the centre of the nebula, also visible in this image as the leftmost star in the bright pair at the centre of the picture.
While the chance alignment of a relatively nearby object – the asteroid – with the distant nebula is fascinating, it is not completely unexpected. In fact, the Crab Nebula, which has been observed by Hubble on nearly 300 occasions, fortuitously lies close to the ecliptic – the orbital plane where most asteroids reside in the Solar System – so it was only a matter of time before one of them ‘photobombed’ an observation of this iconic supernova remnant.
Now that volunteers have perused the platform to spot and mark asteroid trails, it is astronomers’ turn to get to work. Knowing the date and time when the Hubble images were taken, they can use the trails marked in the pictures to infer asteroids’ positions and velocities. This means they can determine the orbits and future trajectories of known and previously unknown asteroids with greater precision than before.
This knowledge is especially important for near-Earth objects: precisely determining the orbits of these asteroids can help protect our planet from possible impacts.
Meanwhile, the ESA team is planning to add new data to the Hubble Asteroid Hunter project soon, so users will have another chance to inspect Hubble images in search of passing asteroids. Stay tuned!
This stunning scene and the Hubble Asteroid Hunter project were made possible thanks to Zooniverse, the world’s largest citizen-science platform. The project was initiated by ESA research fellow Sandor Kruk, graduate student Max Mahlke, software engineers Elena Racero and Fabrizio Giordano from the ESAC Science Data Centre (ESDC) near Madrid, Spain, and Bruno Merín, head of the ESDC.

The We're Here! gang is showing off in our spaceships today.
I took the shot of the Space Shuttle when we were at Kennedy Space Center a few years ago. As I post it right now, I notice that I failed to clone out one of the wires suspending the massive vehicle from the ceiling. Haha. Oh look...two wires! LOL Bonus points if you can find them.
This new multiwavelength image of the Crab Nebula combines X-ray light from the Chandra X-ray Observatory (in blue) with visible light from the Hubble Space Telescope (in yellow) and infrared light seen by the Spitzer Space Telescope (in red). This particular combination of light from across the electromagnetic spectrum highlights the nested structure of the pulsar wind nebula. The X-rays reveal the beating heart of the Crab, the neutron-star remnant from the supernova explosion seen almost a thousand years ago. This neutron star is the super-dense collapsed core of an exploded star and is now a pulsar that rotates at a blistering rate of 30 times per second. A disk of X-ray-emitting material, spewing jets of high-energy particles perpendicular to the disk, surrounds the pulsar. The infrared light in this image shows synchrotron radiation, formed from streams of charged particles spiraling around the pulsar's strong magnetic fields. The visible light is emission from oxygen that has been heated by higher-energy (ultraviolet and X-ray) synchrotron radiation. The delicate tendrils seen in visible light form what astronomers call a "cage" around the rich tapestry of synchrotron radiation, which in turn encompasses the energetic fury of the X-ray disk and jets. These multiwavelength interconnected structures illustrate that the pulsar is the main energy source for the emission seen by all three telescopes. The Crab Nebula resides 6,500 light-years from Earth in the constellation Taurus.

Astronomers have produced a highly detailed image of the Crab Nebula, by combining data from telescopes spanning nearly the entire breadth of the electromagnetic spectrum, from radio waves seen by the Karl G. Jansky Very Large Array (VLA) to the powerful X-ray glow as seen by the orbiting Chandra X-ray Observatory. And, in between that range of wavelengths, the Hubble Space Telescope's crisp visible-light view, and the infrared perspective of the Spitzer Space Telescope.
The Crab Nebula, the result of a bright supernova explosion seen by Chinese and other astronomers in the year 1054, is 6,500 light-years from Earth. At its center is a super-dense neutron star, rotating once every 33 milliseconds, shooting out rotating lighthouse-like beams of radio waves and light -- a pulsar (the bright dot at image center). The nebula's intricate shape is caused by a complex interplay of the pulsar, a fast-moving wind of particles coming from the pulsar, and material originally ejected by the supernova explosion and by the star itself before the explosion.
This image combines data from five different telescopes: The VLA (radio) in red; Spitzer Space Telescope (infrared) in yellow; Hubble Space Telescope (visible) in green; XMM-Newton (ultraviolet) in blue; and Chandra X-ray Observatory (X-ray) in purple.

The Crab Nebula is a supernova remnant some 6500 light-years from Earth in the constellation of Taurus. At the centre of the nebula is a pulsar – the remnant of a star that exploded to form the nebula. The pulsar rotates around 30 times a second, sweeping a beam of radio waves across the Galaxy. Some of the material surrounding the pulsar was ejected before the star exploded, and the rest was expelled during the supernova. The wind from the pulsar escapes at high speed, creating a dynamic structure by interacting with the ejected material.
The nebula is currently expanding at around 1500 km/s, as revealed by images taken a few years apart. By tracing this backwards it is possible to pinpoint the year in which the star exploded, and this coincides with observations by Chinese astronomers in 1054 of a star bright enough to be seen during daylight.
The image shown here is in ultraviolet light taken by ESA’s XMM-Newton telescope, which has been surveying the sky since 2000. While this is primarily a telescope for observing X-rays, the Optical Monitor enables optical and ultraviolet observations to be made simultaneously with X-ray observations. The image is a composite of 75 individual images taken between 2001 and 2015. Very few ultraviolet images of the Crab Nebula were available before this one.
The ultraviolet emission is thought to come from ‘synchrotron radiation’, created when atomic particles spiral around magnetic field lines. The XMM-Newton image reveals ‘bays’ indenting the east and west sides of the nebula. It is thought that a magnetised torus of material surrounded the star before it exploded, which then blocked the high-speed particles and thus the synchrotron radiation. The bays are also evident in radio images, although the eastern bay is better defined owing to intricate features around the borders of the radio image.
This image was taken as part of detailed multi-wavelength study of the Crab Nebula, with images also taken in X-rays, radio waves, infrared and optical wavelengths.
A new composite of the Crab Nebula comprising NASA Chandra and Spitzer data and NASA/ESA Hubble data was also released last week.

A new trio of examples of ‘data sonification’ from NASA missions provides a new method to enjoy an arrangement of cosmic objects. Data sonification translates information collected by various NASA missions -- such as the Chandra X-ray Observatory, Hubble Space Telescope, and Spitzer Space Telescope -- into sounds.
The Crab Nebula has been studied by people since it first appeared in Earth's sky in 1054 A.D. Modern telescopes have captured its enduring engine powered by a quickly spinning neutron star that formed when a massive star collapsed. The combination of rapid rotation and a strong magnetic field generates jets of matter and anti-matter flowing away from its poles, and winds outward from its equator. For the translation of these data into sound, which also pans left to right, each wavelength of light has been paired with a different family of instruments. X-rays from Chandra X-ray Observatory (blue and white) are brass, optical light data from Hubble Space Telescope (purple) are strings, and infrared data from Spitzer (pink) can be heard in the woodwinds. In each case, light received towards the top of the image is played as higher pitched notes and brighter light is played louder.

This image represents a good start in imaging M1, and a good start on learning PixInsight. I have much more to do on both counts.
From an image capture perspective, this is an LRGB image comprised of 25 x 360s luminance subs, 3 x 500s red subs, 3 x 600s green subs, and 3 x 500s blue subs. I seem to have most of the nebulosity captured in the luminance channel, but more data would help. I definitely need more data in the RGB channels. I had to push the saturation too far to get the reds and pinks to show up.. There are no dark, bias or flat frames used to compile this image.
From a processing perspective, this is the first time that I have used PixInsight for LRGB processing since early December, and my first time using it for a nebulous target ever. I think that I have most of the linear processing down fairly well leveraging what I learned with my Orion Constellation OSC images from late January through early March. Most of what I have yet to learn is in the realm non-linear processing.
Where to go next? I used the TeleVue NP101 to shoot this. I could collect more data with this scope, because I think that it looks pretty good for an image scale of 1.39 arcseconds per pixel. Alternatively, I might want to go after it with the 12" f/8 Meade instead of collecting more data with the NP101. I believe that I would need to use 3 x 3 binning of the sensor's 3.76 micron sensors with the Meade, which would result in an image of just less than one arcsecond per pixel. That's a slight improvement, but perhaps the NP101 will win on optics performance? More to learn in this space (sic) as well.

This beautiful jewel in the sky is a supernova remanent (star explosion) in Taurus constellation. It lies about 6500 light years from us with a diameter of around 11ly. It was first reported by Chinese astronomers in 1054. At that time, it was seen as a bight spot in the sky which remained for about 1 month. In the center, there is a neutron star that spins around 30 times per second to emit different kinds of radiations. These radiations are energizing the remanent gases to ignite in these colorful lights. It was assumed that, the gases are expanding in a rate of 1500 km per second. ُGear setup: Celestron Edge HD8 @ f/7, iOptron GEM 45, SW 50 guide scope, ZWO 1600 MM @-10, ZWO EFW 1.25” x 5, ZWO 290MM, Baader SHO 1.25” narrowband filters 6nm.

A team of scientists used NASA’s James Webb Space Telescope to parse the composition of the Crab Nebula, a supernova remnant located 6,500 light-years away in the constellation Taurus. With the telescope’s MIRI (Mid-Infrared Instrument) and NIRCam (Near-Infrared Camera), the team gathered data that is helping to clarify the Crab Nebula’s history.
The Crab Nebula is the result of a core-collapse supernova from the death of a massive star. The supernova explosion itself was seen on Earth in 1054 CE and was bright enough to view during the daytime. The much fainter remnant observed today is an expanding shell of gas and dust, and outflowing wind powered by a pulsar, a rapidly spinning and highly magnetized neutron star.
The Crab Nebula is also highly unusual. Its atypical composition and very low explosion energy previously have been explained by an electron-capture supernova — a rare type of explosion that arises from a star with a less-evolved core made of oxygen, neon, and magnesium, rather than a more typical iron core.

A star's spectacular death in the constellation Taurus was observed on Earth as the supernova of 1054 A.D. Now, almost a thousand years later, a super dense object -- called a neutron star -- left behind by the explosion is seen spewing out a blizzard of high-energy particles into the expanding debris field known as the Crab Nebula. X-ray data from Chandra provide significant clues to the workings of this mighty cosmic "generator," which is producing energy at the rate of 100,000 suns.
This composite image uses data from three of NASA's Great Observatories. The Chandra X-ray image is shown in blue, the Hubble Space Telescope optical images are in yellow and red, and the Spitzer Space Telescope's infrared image is in purple. The X-ray image is smaller than the others because extremely energetic electrons emitting X-rays radiate away their energy more quickly than the lower-energy electrons emitting optical and infrared light. Along with many other telescopes, Chandra has repeatedly observed the Crab Nebula over the course of the mission’s lifetime. The Crab Nebula is one of the most studied objects in the sky, truly making it a cosmic icon.

To celebrate the 25th anniversary of its launch, NASA’s Chandra X-ray Observatory is releasing 25 never-before-seen views of a wide range of cosmic objects.
These images, which all include data from Chandra, demonstrate how X-ray astronomy explores all corners of the universe. By combining X-rays from Chandra with other space-based observatories and telescopes on the ground, as many of these images do, astronomers can tackle the biggest questions and investigate long-standing mysteries across the cosmos.
On July 23, 1999, the space shuttle Columbia launched into orbit carrying Chandra, which was then the heaviest payload ever carried by the shuttle. With Commander Eileen Collins at the helm, the astronauts aboard Columbia successfully deployed Chandra into its highly elliptical orbit that takes it nearly one-third of the distance to the Moon.
The Crab Nebula is the result of a bright supernova explosion witnessed by Chinese and other astronomers in 1054 A.D. Chandra sees the rings around the pulsar and the jets blasting into space. X-rays from Chandra (blue-violet and white) and IXPE (purple); optical from Hubble (red, green, and blue)

This new Hubble image - One among the largest ever produced with the Earth-orbiting observatory - shows gives the most detailed view so far of the entire Crab Nebula ever made. The Crab is arguably the single most interesting object, as well as one of the most studied, in all of astronomy. The image is the largest image ever taken with Hubble's WFPC2 workhorse camera. The Crab Nebula is one of the most intricately structured and highly dynamical objects ever observed. The new Hubble image of the Crab was assembled from 24 individual exposures taken with the NASA/ESA Hubble Space Telescope and is the highest resolution image of the entire Crab Nebula ever made.

La nebulosa Granchio è un resto di supernova visibile nella costellazione del Toro.
È identificata anche come M1, dato che occupa la prima posizione nel catalogo di oggetti astronomici pubblicato da Messier nel 1774.
Il suo diametro apparente è di 6’x4’: per confronto la luna piena ha un diametro di 30’.
La nebulosa, oggi vasta più di sei anni luce, è formata dai gas in espansione espulsi durante l'esplosione di una supernova; la velocità di espansione è di 1500 km/s.
La supernova che la produsse fu osservata per la prima volta il 4 luglio 1054 e venne registrata dagli astronomi cinesi e arabi dell'epoca; era talmente luminosa da essere visibile ad occhio nudo durante il giorno, sorpassando la luminosità apparente di Venere.
La Nebulosa Granchio si trova a circa 6500 al dal sistema solare; perciò l'evento che l'ha prodotta è in realtà avvenuto 6 500 anni prima del 1054, cioè circa nel 5400 a.C.
Al centro della nebulosa si trova la pulsar del Granchio una stella di neutroni con un diametro di circa 28-30 chilometri, scoperta nel 1968: come suggerisce il nome, questa stella emette le sue pulsazioni ogni 33 ms a tutte le lunghezze d'onda dello spettro elettromagnetico, dalle onde radio ai raggi X.
Il curioso soprannome dato a questa nebulosa risale alla metà del 1800 per opera di William Parson, poiché lo schizzo che aveva fatto della nebulosa dopo averla osservata con il suo potente telescopio ricordava l'aspetto di un granchio.
----------
The Crab Nebula is a supernova remnant in the constellation Taurus. It is also identified as M1, as it occupies the first position in the catalog of astronomical objects published by Messier in 1774.
Its apparent diameter is 6'x4': for comparison the full moon has a diameter of 30'.
The nebula, now more than six light-years wide, is formed by the expanding gas expelled during a supernova explosion; the expansion speed is 1500 km/s.
The supernova that produced it was observed for the first time on July 4, 1054 and was recorded by Chinese and Arab astronomers of the time; it was so bright that it was visible to the naked eye during the day, surpassing the apparent brightness of Venus.
The Crab Nebula is located about 6500 years from the solar system; therefore the event that produced it actually occurred 6 500 years before 1054, i.e. around 5400 BC.
At the center of the nebula is the Crab pulsar, a neutron star with a diameter of about 28-30 kilometers, discovered in 1968: as the name suggests, this star emits its pulsations every 33 ms at all wavelengths of the electromagnetic spectrum, from radio waves to X-rays.
The curious nickname given to this nebula dates back to the mid-1800s by William Parson, since the sketch he made of the nebula after observing it with his powerful telescope resembled the appearance of a crab.
