Poetry: moonless night sky
Poetry: moonless night sky
I like the moonless night sky.Somehow the heavens twinkle brighter without the jarring moon being a distraction from the endless galaxies created from dust.

when things get this wild, not even an event horizon can contain the party

Jauz & HALIENE Deliver New Single "Oceans & Galaxies" via Monstercat [LISTEN]
Jauz & HALIENE Deliver New Single “Oceans & Galaxies” via Monstercat [LISTEN]
Jauz and HALIENE join forces to deliver on a dreamy, downtempo track, “Oceans & Galaxies” for Monstercat. While streaming on Twitch early in the pandemic, the pair made friends and thus the song was born. Fittingly, the production features HALIENE’s atmospheric vocals, accompanied by a trance-like melody and oceanic bass. The lyrics illustrate a love story that transcends distance. Jauz…

Abell 1033: to boldly go into colliding galaxy clusters
Tumblr media
hidden in a distant galaxy cluster collision are these multi-million-degree gas wisps and jets filling the space between galaxies. this superheated gas is invisible to optical telescopes, but shines brightly in X-rays
galaxy clusters — cosmic structures containing hundreds or even thousands of galaxies — are the largest objects in the universe, and the mass of this cluster's hot gas is many times greater than all its galaxies, combined
the jets are traveling at close to the speed of light. as the galaxy and its black hole moved toward the lower part of the image, the jet on the right slowed down as it crashed into hot gas in the other galaxy cluster. the jet on the left did not slow down because it encountered much less hot gas, warping the jets
...adding warp drive to this Enterprise

The centre of M87, a massive elliptical galaxy some 53.5 Million light years from Earth is home to a truly gigantic supermassive black hole.
The Milky way's supermassive black hole is large, at 4.3 million times the mass of our Sun, but M87 however makes it look like a tiny star in comparison, at over 5 billion solar masses.
Tumblr media
The difference is so much, that when we are in the market for trying to find a good black hole to take a picture of, M87 was the natural choice.
Tumblr media
Let's step back a little and ask a few questions about these monsters, how on earth did this galaxy end up with such a huge black hole at its centre, while the Milky Way didn't.
Supermassive black holes theoretically form as mergers and feeders. When two black holes collide they merge. Stellar black holes are created when very large stars collapse at the end of their life, and over time they circle around our galaxy and eventually make their way towards the centre, merging in with any existing black hole there.
Tumblr media
So the more frenzied star birth, the more massive stars, the more black holes and ultimately, the larger the central black hole will become over billions of years.
The second method of growth is, black holes don't just pull in other black holes, they pull in matter from everywhere, be it hydrogen gas, dust, stellar remnants, white dwarfs, stars, neutron stars, and you if you got close enough ! They can be incredibly greedy, and grow very quickly if fed enough.
Tumblr media
So lets look at the size of both galaxies, the Milky way has around 100 thousand million stars it's relatively stable, it has areas of intense star birth, but nothing like on the scale of some galaxies (known as starburst galaxies).
M87 has several trillion stars, so is orders of magnitude larger than the Milky Way, it has next to no star formation, areas of nebulosity or dust lanes.
Tumblr media
The Milky Way compared is far more dynamic, but the calm of M87 hides a very violent past, of many galaxy mergers and huge star creation that led to it having such a massive size and supermassive black hole.
The black hole is now so large, it heats up the surrounding galaxy, stunting any star formation and rendering itself sterile, until another galaxy happens towards it !
In comparison the life of the Milky Way has been fairly quiet, it's made a few minor acquisitions over its life of dwarf sized galaxies, but no mega mergers, until Andromeda galaxy comes our way in a few billion years and a 250 million solar mass black hole piles into our galaxy and possibly ends the age of the spiral nature of our galaxy too.

The Galaxy CQ4479 
The extremely active black hole at the galaxy’s center is consuming material so fast that the material is glowing as it spins into the black hole’s center, forming a luminous quasar. Quasars were thought to end a galaxy’s life but the galaxy CQ4479 is surviving by continuing to birth new stars-about 100 Sun-sized stars a year.

Where Do Galaxies Come From?
“If Hubble showed us what the Universe looks like, then James Webb will teach us how the Universe grew up into what it is today. We have direct information, going back to the very early stages of the Big Bang, that illuminates what the seeds of our modern galaxies look like, and we have direct information some 400 million years later, showing us what those early-type galaxies have grown into. From those early times to the present day, we can fill in a remarkable number of those subsequent details, but we have no observational clues as to how those first galaxies truly arose.
The James Webb Space Telescope, just six months from now, will launch towards its ultimate destination. By 2022, we should begin taking observations of the deepest corners of the Universe: those far reaches that have been invisible to every other observatory thus far. We have a theoretical picture for how galaxies ought to arise, and at last, the observational data is about to catch up. Whatever it is that we find will be a thrilling victory for the enterprise of science, with chances to discover something more revealing than anyone has yet anticipated.”
Astronomy is an ambitious science. Our goal is to observe, understand, and characterize every object out there in the Universe, including what they are and how they came to be. For galaxies, we can observe them going back to when the Universe was only 3% its current age, but before that, there’s an enormous gap. The first galaxies, the earliest stars, and the collapsing matter that gave rise to them are all obscure to us right now.
But in just one more year, the James Webb Space Telescope may change all of that, giving us observational data to confront our theories with. Here’s what we know, and here’s what we’ll learn.

New Distances Support Idea of Dark Matter–less Galaxies - Sky & Telescope
New Distances Support Idea of Dark Matter–less Galaxies – Sky & Telescope
New distance measurements of two strange galaxies in the constellation Cetus, the Whale, support the notion that they are almost devoid of dark matter — the mysterious stuff that constitutes 85% of all gravitating mass in the universe. Astronomers are at a loss to explain the apparent absence of dark matter in the two systems. A survey image taken with the Dragonfly Telephoto Array shows objects…
