The 2006 Chandra three-color image (inset) of a region of the supernova remnant Puppis A (wide-angle view from ROSAT in blue) reveals a cloud being torn apart by a shock wave produced in a supernova explosion. This is the first X-ray identification of such a process in an advanced phase. In the inset, the blue vertical bar and the blue fuzzy ball or cap to the right show how the cloud has been spread out into an oval-shaped structure that is almost empty in the center. The Chandra data also provides information on the temperature in and around the cloud, with blue representing higher temperature gas.
The oval structure strongly resembles those seen on much smaller size scales in experimental simulations of the interaction of supernova shock waves with dense interstellar clouds (see sequence of laboratory images). In these experiments, a strong shock wave sweeps over a vaporized copper ball that has a diameter roughly equal to a human hair. The cloud is compressed, and then expands in about 40 nanoseconds to form an oval bar and cap structure much like that seen in Puppis A.
On a cosmic scale, the disruption of l0-light-year-diameter cloud in Puppis A took a few thousand years. Despite the vast difference in scale, the experimental structures and those observed by Chandra are remarkably similar. The similarity gives astrophysicists insight into the interaction of supernova shock waves with interstellar clouds.
Understanding this process is important for answering key questions such as the role supernovas play in heating interstellar gas and triggering the collapse of large interstellar clouds to form new generations of stars.

Interstellar
The Geminid Meteor Shower is my favorite night out haunt & yet is such a big deal breaker...You know, it falls on our marriage anniversary. Being out the entire night, alone as you might have guessed it, is a big No-No, if I want to stay happily married & yet such are the magnetic powers of these interstellar meteors, that in spite of them falling on almost the same anniversary days, every year I keep a date with "The GMS," with many electoral promises given to my better half.
Geminid meteor shower is not just one shot but a wholesome experience. I reached around sundown & after a 40 minutes hike up the steep incline with my twenty-two kgs of equipment, pitched the tent on top of the Don Hill Station, which now is reckoned as the second highest hill of Gujarat. The shooting began at twilight & lasted till three in the morning. It was one real frigidly cold & windy night with the tent promising to blow away any time but it was one awesome experience. To creak your neck up & see these frequent streaks of magical light radiate from the Gemini constellation & dash all over the sky brought a childlike exuberance. Each shooting star as otherwise called in a layman's parlance, made me cross my fingers & make me wish that I'd not skip my anniversary next year to photograph this again! B|
Wishful thinking!
Happy Anniversary Neha! :)
This photograph is a composite image of ten images taken during the whole shower.
The enemy possessed power unseen in this galaxy. In the very first weeks of invasion, before the word 'war' was even uttered, they've caused annihilation of the world of Sernpidal, bringing it's moon down. Caught in the disaster, a mighty hero of the Civil War sacrificed his life for the hope of tomorrow.
This is how the era of New Jedi Order begun.

This is my parents garden, I go there most weekends and sometimes annoy my mother by taking a doll with me. This tree flowered so quickly, I wasn’t expecting it at all but was glad I’d brought Stellar with me last weekend. It was raining a little but she didn’t mind 🌸
Shark nebula LDN1235 is a dark / Reflection nebula located in Cepheus constellation. It’s composed of interstellar dust that hiding stars behind it. Gear setup: Celestron RASA 8 f/2, iOptron GEM45, ZWO 30 Mini + ZWO120MM-S, ZWO 2600MC @0C, Optolong L-Pro 2”. Light subs 120 x 300sec, total exposure 10 hours. Captured by NINA, PHD2. Stacked in APP and Processed in PI. Imaged from sky Bortle class 4.
One of the things I appreciated when I visited London's new Elizabeth Line is the futuristic stylings of the station architecture. It's like something from a giant spaceship. Hopefully I will get a chance to be there early one morning when there are far fewer people, so I can more easily capture the cold starkness of the tunnels and walkways.
This low-angle shot was facilitated nicely by the tilting rear LCD screen of my Fujifilm X-T2; it's not fully articulated but tilts up 90° which is perfect for this kind of shot. To frame the same composition successfully with my Canon 6D I'd have to be lying on the floor!
The lives of planetary nebulae are often chaotic, from the death of their parent star to the scattering of its contents far out into space. Captured here by the NASA/ESA Hubble Space Telescope, ESO 455-10 is one such planetary nebula, located in the constellation of Scorpius (The Scorpion).
The oblate shells of ESO 455-10, previously held tightly together as layers of its central star, not only give this planetary nebula its unique appearance, but also offer information about the nebula. Seen in a field of stars, the distinct asymmetrical arc of material over the north side of the nebula is a clear sign of interactions between ESO 455-10 and the interstellar medium.
The interstellar medium is the material — consisting of matter and radiation — between star systems and galaxies. The star at the centre of ESO 455-10 allows Hubble to see the interaction with the gas and dust of the nebula, the surrounding interstellar medium, and the light from the star itself. Planetary nebulae are thought to be crucial in galactic enrichment as they distribute their elements, particularly the heavier metal elements produced inside a star, into the interstellar medium which will in time form the next generation of stars.

In this image the NASA/ESA Hubble Space Telescope takes a close look at the spiral galaxy NGC 4217, located 60 million light-years away from Earth. The galaxy is seen almost perfectly edge on and is a perfect candidate for studying the nature of extraplanar dust structures — the patterns of gas and dust above and below the plane on the galaxy, seen here as brown wisps coming off NGC 4217.
These tentacle-like filaments are visible in the Hubble image only because the contrast with their surroundings is so high. This implies that the structures are denser than their surroundings. The image shows dozens of dust structures some of which reach as far as 7,000 light-years away from the central plane. Typically the structures have a length of about 1,000 light-years and are about 400 light-years in width.
Some of the dust filaments are round or irregular clouds, others are vertical columns, loop-like structures or vertical cones. These structures can help astronomers to identify the mechanisms responsible for the ejection of gas and dust from the galactic plane of spiral galaxies and reveal information on the transport of the interstellar medium to large distances away from galactic disks.
The properties of the observed dust structures in NGC 4217 suggest that the gas and dust were driven out of the mid-plane of the galaxy by powerful stellar winds resulting from supernovae — explosions that mark the deaths of massive stars.

You'd be shortchanging yourself if you didn't occasionally glance upwards while in Lower Manhattan's Financial District. Like here in this shot, deep in the canyon somewhere between towering One WTC (left), The New York Academy of Sciences (right) and the Verizon Corporate office in the centre, you could probably see the stars. It was partly cloudy, so I missed out!

This is an amazing object a comet from outside our Solar System perhaps formed well before the Sun and our Solar System came to exist. Just passing through our neighborhood, this is the first one of these objects that is easily accessible to amateur telescopes.

spent a week driving in and out of town in seek of documenting the perseid meteor shower 🌠with @surfnsnowboard and @theisaacgibbs. one location i have always wanted to visit was the radar dome. so glad i was finally able to document this soccer-ball like object under the MW🌌. fun fact, i captured a meteor in this photo but instagram’s crop cut it off because i’d have to sacrifice too much foreground. this was also one of my very first shoots on my new 5DMk4. it was a fun week even though my astronomy tracker kept messing up. who knows, maybe i’ll get around to processing more photos from this adventure. ••

This beautiful clump of glowing gas, dark dust and glittering stars is the spiral galaxy NGC 4248, located about 24 million light-years away in the constellation of Canes Venatici (The Hunting Dogs).
This image was produced by the NASA/ESA Hubble Space Telescope as it embarked upon compiling the first Hubble ultraviolet “atlas,” for which the telescope targeted 50 nearby star-forming galaxies. The collection spans all kinds of different morphologies, masses, and structures. Studying this sample can help us to piece together the star-formation history of the Universe.
By exploring how massive stars form and evolve within such galaxies, astronomers can learn more about how, when, and where star formation occurs, how star clusters change over time, and how the process of forming new stars is related to the properties of both the host galaxy and the surrounding interstellar medium (the gas and dust that fills the space between individual stars).
This galaxy was imaged with observations from Hubble’s Wide Field Camera 3.

Depictions of two kinds of dust in space: At left the pyramid-shaped glow of Zodiacal Light caused by sunlight reflecting off interplanetary dust in the inner solar system from comets and meteoroids, while at right is the band of the bright Milky Way, made of stars in our galaxy. But along it lie dark lanes of interstellar dust made of carbon compounds made in the atmospheres of stars and dispersed into the Galaxy.
