GALAXIES

We describe what it means for galaxies to collide given the great distances between stars within each galaxy. We then take a look at some of the interacting galaxies photographed by the Hubble Telescope. These include: The Antennae Galaxies, The Mice, NGC 2207 with IC 2163; Apr 256; ESO 576-69; APR 142; NGC 6240; the Tadpole Galaxy; UCG 1810 with UCG 1813; the spectacular APR 147; NGC 454; South America Galaxy; and ZW II 28. We spend some time on peculiar galaxy NGC 7603 with its multiple red-shift objects that challenge well accepted theories on Dark Matter and Cosmology. Next, we discuss how we go about seeing a process that takes a billion years by observing interactions at various stages along the process as understood by computer simulations. Here we show a few that illustrate the phases of an interaction: the initial approach with NGC 6786 and LEDA 62867; first contact with VV 304A and VV 304B; penetration with Mayall’s Object; out the other side with ESO 77-14; wrap around with VV 705; and merge with The Owl. We end with another simulation. This time it’s the collision between Andromeda and the Milky Way.

The Hubble Space Telescope has been revealing the secrets of the universe for over 30 years, but it turns out Hubble has some secrets of its own! The question is: Hubble has helped confirm that the Milky Way will merge with which nearby galaxy? You might be surprised! See if you know the trivia question before the answer comes up on the screen!

Hi Spacecats, I'm Dr Maggie Lieu and welcome to my channel, where you can find all things space, astronomy and physics! Have you ever wondered how astronomers know how far away things are? It turns out the the method they use to determine an astronomical object's distance, depends on what it is!

Cosmographers recently revealed a massive wall of galaxies lurking shockingly close by. But why was it hidden from our view for so long? » Subscribe to Seeker! http://bit.ly/subscribeseeker » Watch more Elements! http://bit.ly/ElementsPlaylist » Visit our shop at http://shop.seeker.com Cosmographers’ goal is to map out the observable universe, and from their findings we can not only learn more about the structures that make up everything we can see, we also gain insight into the things we cannot see. The universe is full of massive structures hidden from our view, like the area of the sky above the South Pole that has been dubbed the “Zone of Avoidance,” in our very own Milky Way. Some cosmographers pulled out some clever tricks to peer into the Zone of Avoidance. Using a catalog of the motions and distances of 18,000 galaxies called Cosmicflows-3, the scientists noticed that some galaxies were moving faster or slower than expected, and seemed to be drawn to something in the middle, something hidden in the Zone of Avoidance. Computer models revealed a wall made up of thousands of galaxies at least 600 million light-years deep and 1.4 billion light-years across, forming a bow shape over the southern hemisphere’s sky.

As astronomers, one thing we feel like we understand is the shapes of galaxies. But then sometimes something like NGC 474 comes along and crushes those dreams. Luckily we can use the weird mess around NGC 474 as a "whodunnit" to figure out the history of this weird and wonderful galaxy, one that seems to include "galactic cannibalism"... #spaceisweird #weirdisgood #astrophysics Arp (1966) - http://articles.adsabs.harvard.edu/pdf/1966ApJS...14....1A Interactive version of Arp (1966) - Atlas of Peculiar Galaxies - https://ned.ipac.caltech.edu/level5/Arp/paper.pdf Cooper et al.

It is 2.5 million light years away from Earth. It is the most distant naked eye object you can see in the night sky. Although several dozen minor galaxies lie closer to our Milky Way, the Andromeda galaxy is the closest large spiral galaxy to ours. It is the nearest major galaxy to the Milky Way and it gets its name from the area of the sky from which it appears the constellation of Andromeda, which was named after the Greek mythological princess Andromeda. Here are five fascinating facts about the Andromeda galaxy. 5. Andromeda Has One Trillion Suns. There are around one trillion suns in the Andromeda Galaxy, compared to between 100 and 400 billion stars for our own Milky Way galaxy. Not only does it have a lot more stars than the milky way, Andromeda is enormous with a diameter of around 220,000 light-years across, which is nearly one and a half times longer than the Milky Way. Despite that, the mass of the Andromeda Galaxy is only 400 billion times that of our own Sun. The Milky Way is imagined to be considerably heavier because it probably possesses more Dark Matter and Dark Energy than the Andromeda galaxy. 4. Andromeda Appears Six Times the Size of our Moon. 3. Andromeda is Full of Black Holes. 2. Andromeda and Milky Way will collide. 1. Andromeda Was Once Thought To Be A Nebula. Credit: NASA/ESA

This lecture is part of the free and open to the public lecture series for the Royal Astronomical Society's bicentenary celebrations in 2020. How did our Galaxy form? Is there only one way to form a spiral galaxy like ours, or can they form in different ways? And what role does the mysterious dark matter play in galaxy formation? One way to address these key questions is through the forensic, star-by-star analysis of nearby galaxies. By treating each star as a fossil of galactic evolution, we can piece together a road-map for how the beautiful spiral galaxies of the Universe are produced. In this talk, I’ll discuss what we know about the formation and evolution of the Milky Way and Andromeda, and how Galactic Archaeology can help us better understand the formation of all spiral galaxies.

Professor Mike Merrifield discusses a different way to look at galaxies.

Dr. Benne Holwerda, University of Louisville One of the largest spiral galaxies in the known local universe, UGC 2885, was recently nicknamed Rubin’s Galaxy in honor of Dr. Vera Rubin, who studied its rotation in the 1980s and found evidence for the existence of dark matter. A new, 74-megapixel, mosaic image of the galaxy from the Hubble Space Telescope was released in January. Dr. Benne Holwerda of the University of Louisville will present “Rubin's Galaxy: A Gentle Giant Spiral Galaxy” on Wednesday, June 3, 2020 at 3:30 pm EDT, to describe his observations and how the large galaxy provides an intriguing test of the observed scaling relationships between the characteristics of a galaxy and the characteristics of its globular star cluster population. Recorded live on Wednesday, June 3, 2020. More information: www.stsci.edu/public-lectures

Not every galaxy is a fully formed spiral or elliptical galaxy. Some are much smaller, and orbit larger galaxies as well as each other, like ghosts.

Most of the galaxies we observe are considered normal. We inhabit a normal galaxy called the Milky Way. When you observe a normal galaxy, most of the light comes from the stars in visible wavelengths and is evenly distributed throughout the galaxy. But if you look at some galaxies, you will see intense light coming from their nuclei. These are active galaxies.
