UGC 1810: Wildly Interacting #Galaxy from #Hubble

UGC 1810's blue outer ring and shape result from a clash with its galactic neighbor, forming part of Arp 273. The blue hue comes from newly formed massive stars. Its older, redder core is laced with dust. Foreground stars and background galaxies dot the view. Located 300 million light-years away, UGC 1810 may eventually absorb its companion.

UGC 1810: Wildly Interacting Galaxy from Hubble

Every time I see a picture or video of the size of the universe, it takes my breath away.

Remember the ' most important picture ever made' (see attachments)?

This one-minute video is beautifully done.

So what we are seeing is a continuing video made by #ESA with photos or videos taken by the #Hubble Telescope but then reversed to make show what the #Earth, or our Milky Way, would look like when watching from the outside in?

The most important picture ever taken 1/2. he blank region of sky, shown in the yellow L-shaped box, was the region chosen to be the observing location of the original Hubble Deep Field image. With no known stars or galaxies within it, in a region devoid of gas, dust, or known matter of any type, this was the ideal location to stare into the abyss of the empty Universe.
The streaks and arcs present in Abell 370, a distant galaxy cluster some 5-6 billion light-years away, are some of the strongest evidence for gravitational lensing and dark matter that we have. The lensed galaxies are even more distant, with some of them making up the most distant galaxies ever seen. The Frontier Fields program searches for lensed galaxies by deeply imaging galaxy clusters.

Spiral Galaxy NGC 4217 edge on
This image was entered into the Hubble Hidden Treasures competition by contestant Ralf Schoofs

Explanation:
In this image the NASA/ESA Hubble Space Telescope takes a close look at the spiral galaxy NGC 4217, 60 million light-years away. 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 7000 light-years away from the central plane. Typically the structures have a length of about 1000 light-years and are about 400 light-years in width. Some of the dust filaments are round or irregular clouds, others are vertical columns, looplike 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 discs. The properties of the observed dust structures in NGC 4217 suggest that the gas and dust was driven out of the midplane of the galaxy by powerful stellar winds resulting from supernovae — explosions that mark the deaths of massive stars.

Explanation:
A gorgeous spiral galaxy, Messier 104 is famous for its nearly edge-on profile featuring a broad ring of obscuring dust lanes. Seen in silhouette against an extensive central bulge of stars, the swath of cosmic dust lends a broad brimmed hat-like appearance to the galaxy suggesting a more popular moniker, the Sombrero Galaxy. This sharp view of the well-known galaxy was made from over 10 hours of Hubble Space Telescope image data, processed to bring out faint details often lost in the overwhelming glare of M104's bright central bulge. Also known as NGC 4594, the Sombrero galaxy can be seen across the spectrum, and is host to a central supermassive black hole. About 50,000 light-years across and 28 million light-years away, M104 is one of the largest galaxies at the southern edge of the Virgo Galaxy Cluster. Still, the spiky foreground stars in this field of view lie well within our own Milky Way.

This is Hen 2-104 aka the Southern Crab Nebula!

It's a planetary nebula with a symbiotic star system at its center 🤩

It's located in the #constellation #Centaurus

To learn more about the #astronomy of the constellation Centaurus -- check out: starrytimepodcast.podbean.com/

If you want to know who the Centaur is, check out out our #Mythology episode: starrytimepodcast.podbean.com/

Image of The Southern Crab Nebula captured by the Hubble Space Telescope. This planetary nebula is comprised of a symmetrical, butterfly-like structure with bright, glowing filaments of gas and dust expanding outward from a central white ring. The nebula appears to have four main lobes, glowing in shades of gold, blue, and orange, set against a black background. Distant stars are scattered throughout the image.

👀 On our radar: Happy (belated) 35th birthday, Hubble!

💬 “For 35 years Hubble has pushed the boundaries of possibility, transforming our view of the cosmos each time it beams the universe’s light down to Earth.”
