5 Galaxies !!BETTER!!
The actual deployment of the telescope, however, took place on April 25, 1990, when the Space Shuttle Discovery opened up its cargo bay and let the 43-foot telescope out into Earth orbit. The five galaxies in the birthday image are collectively known as Hickson Compact Group 40 (HCG 40).
According to the National Astronomical Observatory of Japan, galaxies are rarely found alone in space. HCG 40 qualifies as an assembly of galaxies, and larger collections are known as clusters or groups.
According to the European Space Agency, the galactic wings are part of the VV689 system, also known as the Angel Wing, which can be seen in the night sky in the constellation Leo. The distinctive wing-like appearance results from a catastrophic collision between two galaxies that have been merging for billions of years.
Screen Rant said colliding galaxies often occur across the cosmos, though their appearance varies greatly. The collision of these two galaxies gives them a symmetrical and wing-like form, earning them the official designation of 'Angel Wing.'
In 2012, Hubble caught an image of what seemed to be two overlapping galaxies, dubbed NGC 3314, that appeared to be colliding. According to ESA, it was just a matter of perspective in that circumstance.
Many galaxy collisions are unavoidable, and they have been in the works for billions of years. Scientists can anticipate if and when galaxies collide by watching how they move relative to each other. Astronomers have estimated that the Milky Way will collide with our neighboring galaxy, Andromeda, in roughly 5 billion years.
According to Science Alert, the cluster has three spiral-shaped galaxies ringed by orange dust clouds, a lens-like galaxy on the lower right, and an elliptical galaxy towards the top, all engaged in a compact gravitational dance.
While tight clusters of galaxies are not uncommon, they are most commonly seen near the center of bigger galaxy clusters. On the other hand, HCG is located in the constellation Hydra and is exceptionally isolated from everything else, making it an exciting topic for research, according to a statement.
NASA's James Webb Space Telescope today revealed never-before-seen details of galaxy group called "Stephan's Quintet". The image shows in rare vivid detail how interacting galaxies trigger star formation in each other and how gas in galaxies is being disturbed, NASA said.
The image captures sweeping tails of gas, dust and stars that are being pulled from several of the galaxies due to gravitational interactions and most dramatically, James Webb Space Telescope captures huge shock waves as one of the galaxies, NGC 7318B, smashes through the cluster.
NASA says that it is rare for scientists see in so much detail how interacting galaxies trigger star formation in each other, and how the gas in these galaxies is being disturbed. Stephan's Quintet is a fantastic "laboratory" for studying these processes fundamental to all galaxies.
This week will see a special day for all those who are fans of astronomy or of admiring beautiful space images. The Hubble Space Telescope is celebrating its birthday on Sunday, April 24, 2022, which will mark 32 years since the launch of this remarkable instrument in 1990. To commemorate the event, the Hubble team has shared a special image captured by the telescope showing not one, but five galaxies grouped together in what the researchers describe as a "menagerie" (via Hubble).
As well as being a neat image, collecting data on such a densely packed group of galaxies can help astronomers learn about dark matter. Normally, dense groups of galaxies are found in the center of enormous galaxy clusters, but this particular group is out on its own, relatively far from other galaxies. Researchers think this might be because these galaxies are hosting a large amount of dark matter.
We can see three spiral galaxies, marked by orange colour visible due to space dust. The one in the middle is an elliptical galaxy. The one in the bottom right corner is a lenticular (lens-like) galaxy.
World 5: Trial of the Galaxies is the fifth world featured in Super Mario Galaxy 2. World 5 is a galaxy cluster. It holds seven galaxies, the last of which, Bowser Jr.'s Boom Bunker, features the third and last encounter with Bowser Jr., who now attacks with his Boomsday Machine.
Good morning. I'm Steve Inskeep. Scientists have peered into the distant past. Astronomers say in the journal Nature they discovered six galaxies that existed 5- and 700 million years after the Big Bang - so billions of years ago. Researchers using the Webb Telescope were so surprised by the discovery they weren't sure it was real at first. I guess that's something that can happen with galaxies from a long time ago that are far, far away. It's MORNING EDITION.
An enormous mosaic of Stephan's Quintet is the largest image to date from NASA's James Webb Space Telescope, covering about one-fifth of the Moon's diameter. It contains over 150 million pixels and is constructed from almost 1,000 separate image files. The visual grouping of five galaxies was captured by Webb's Near-Infrared Camera (NIRCam) and Mid-Infrared Instrument (MIRI).
Many astronomers insisted the streams of material between NGC 7320 and the other galaxies proved they were physically bound together in space. Moreover, all five galaxies have approximately the same apparent size, further evidence they sit at the same distance. After all, if the low-redshift galaxy was really much closer to us, shouldn't it appear far larger than the others?
Cosmologists let out a collective sigh of relief. Redshift is reliable after all. The universe is safe. Astronomers now prefer to label the four galaxies that are actually a physically bound unit as Hickson Compact Group 92. This actually includes a separate galaxy that was not a part of the original quintet, so that even though NGC 7320 has been expelled from the club, Compact Group 92 remains a fivesome.
With its powerful, infrared vision and extremely high spatial resolution, Webb shows never-before-seen details in this galaxy group. Sparkling clusters of millions of young stars and starburst regions of fresh star birth grace the image. Sweeping tails of gas, dust and stars are being pulled from several of the galaxies due to gravitational interactions. Most dramatically, Webb captures huge shock waves as one of the galaxies, NGC 7318B, smashes through the cluster.
Researchers at the University of Copenhagen's Niels Bohr Institute have just discovered two previously invisible galaxies billions of light-years away from Earth. The two galaxies have been invisible to the optical lens of the Hubble Space Telescope, hidden behind a thick layer of cosmic dust that surrounds them.
But with the help of the giant ALMA radio telescopes (Atacama Large Milimeter Array) in Chile's Atacama Desert, which can capture radio waves emitted from the coldest, darkest depths of the universe, the two invisible galaxies suddenly appeared.
"We were looking at a sample of very distant galaxies, which we already knew existed from the Hubble Space Telescope. And then we noticed that two of them had a neighbor that we didn't expect to be there at all. As both of these neighboring galaxies are surrounded by dust, some of their light is blocked, making them invisible to Hubble," explains Associate Professor Pascal Oesch of the Cosmic Dawn Center at the Niels Bohr Institute.
The new discovery suggests that the very early universe contains many more galaxies than previously assumed. They simply lie hidden behind dust consisting of small particles from stars. However, they can now be detected thanks to the highly sensitive ALMA telescope and the method used by the researchers.
By comparing these new galaxies with previously known sources in the very early universe, approximately 13 billion years ago, the researchers estimate that between 10 and 20 percent of such early galaxies may still remain hidden behind curtains of cosmic dust.
"Our discovery demonstrates that up to one in five of the earliest galaxies may have been missing from our map of the heavens. Before we can start to understand when and how galaxies formed in the Universe, we first need a proper accounting," says Pascal Oesch.
"The next step is to identify the galaxies we overlooked, because there are far more than we thought. That's where the James Webb Telescope will be a huge step forward. It will be much more sensitive than Hubble and able to investigate longer wavelengths, which ought to allow us to see these hidden galaxies with ease," states Pascal Oesch, adding:
"We are trying to put the big puzzle about the universe's formation together and answer the most basic question: 'Where does it all come from?' The invisible galaxies that we've discovered in the early universe are some of the first building blocks of the mature galaxies we see around us in the Universe today. So that's where it all began."

The primordial galaxies existed just 500 to 700 million years after the Big Bang, yet they have masses that approach 100 billion times that of the Sun, making them almost as hefty as the modern Milky Way.
Labbé and his colleagues discovered the galaxies in observations captured by the James Webb Space Telescope (JWST), the most powerful observatory ever launched into space, which is a collaboration between NASA, the European Space Agency, and the Canadian Space Agency.
JWST, which is the successor to the Hubble Space Telescope, has revolutionized our view of the universe ever since it became operational last year, revealing the earliest galaxies ever seen by humans, among other mind-boggling observations. Now, the sophisticated new observatory has delivered yet another cosmic bombshell by glimpsing these six inexplicable galaxies that existed more than 13 billion years ago. 041b061a72
