Observing The Beautiful 💫 ANDROMEDA CONSTELLATION in Space

#shorts #andromeda #constellation #space

To Watch The Video of Observing The Andromeda Constellation visit my Youtube Channel @InfinityASTRONOMERICA

About the Video :

The Andromeda constellation consists of 16 stars visible in the northern sky. Named by ancient Greeks after the mythological Andromeda princess, the constellation contains the Andromeda Galaxy, the nearest full-fledged galaxy to our own Milky Way.

It is a barred spiral galaxy and is the nearest major galaxy to the Milky Way. It was originally named the Andromeda Nebula and is cataloged as Messier 31, M31, and NGC 224. Andromeda has a diameter of about 46.56 kiloparsecs (152,000 light-years) and is approximately 765 kpc (2.5 million light-years) from Earth. The galaxy's name stems from the area of Earth's sky in which it appears, the constellation of Andromeda, which itself is named after the princess who was the wife of Perseus in Greek mythology.

Biblically Accurate Astronomers (pt. 1). They tolerate each other.

If you’re curious, Al-Zarqali is an astrolabe, and Ptolemy is an armillary sphere.

Do you think Ichika has a crush on Kazui?

who knows!

#personally....i don't care since they're both still so little #and as objective as i am about bleach's strengths and flaws i have always loved ichihime and renruki lol i think it's going to take a lot #for kubo to get people (or at least me) to care about them as much as i did with their parents #they're not fully 'characters' yet so any guess i make would just be me taking a shot in the dark #boring answer as always but my standard reply for anything post-canon is: we don't have information #check back with me for a solid answer in maybe 30 years if he ever gets around to finishing the arc and i'm still around somehow #but until then i'm going to go with a cop-out answer🤷🏽‍♀️ in my head they probably grow up to be mlm/wlw besties anyway so...#if he IS building something there it's got to be astronomical for me to care #especially after we got orihime's confession and renji's narration of his backstory with rukia like that was PEAK to me idk #and if there is a post-canon arc in the works i would still like it to focus on their parents. not sure if i'm ready to pass the baton yet #sorry i know this did not answer your question at all but i didn't want to lie with a yes/no answer😅#asks

earth is actually a binary planetary system (luna is not exactly a typical moon)

also pluto and charon are a binary dwarf planet system

our solar system is so fucking weird actually and this may or may not have anything to do with life developing here! could be a coincidence! could be the deciding factor! who knows!

#sometimes lifelong special interests roar back to life after years of dormancy #and suddenly i'm confused that people around me don't have the gravitation constants of various astronomical bodies memorized #when science fiction writers assume the audience is roughly familiar with the size and gravity of various planetary objects?#that's for me. i'm the audience that goes oh so it's like mercury #i see #and is actually enlightened

Capturing the "Beauty of the Universe" Astrophotography with Small Telescopes

Astrophotography with small telescopes is an excellent way for amateur astronomers to capture stunning and detailed images of the universe. This form of photography involves taking images of celestial objects such as planets, stars, galaxies, and other deep-sky objects using a small telescope.

The process of astrophotography with small telescopes involves attaching a camera to the telescope and then using the telescope to track the object being photographed. This allows for long exposure times which are essential for capturing the faint light emitted by celestial objects.

Benefits of Astrophotography

One of the benefits of astrophotography with small telescopes is that it is accessible to a wide range of amateur astronomers. Small telescopes are affordable and easy to use, making them a popular choice for those who are just starting with astrophotography. When it comes to astrophotography with small telescopes, there are several different techniques that you can use to capture stunning images of the universe.

For example, planetary photography involves capturing detailed images of planets such as Jupiter, Saturn, and Mars. Deep-sky astrophotography, on the other hand, involves taking images of galaxies, nebulae, and other deep-sky objects.

Good Quality Telescope

To get started with astrophotography with small telescopes, you will need a few essential pieces of equipment. A good quality telescope, mount, and camera are all essential for capturing high-quality images. Additionally, you may want to invest in filters, which can help to enhance the details of your images.

Explore the Universe

Overall, astrophotography with small telescopes is a fantastic way for amateur astronomers to explore the universe and capture stunning images of celestial objects.

Whether you are interested in planetary photography or deep-sky astrophotography,there are many different techniques that you can use to capture the beauty of the universe. So, if you are passionate about astronomy and are interested in exploring the universe, astrophotography with small telescopes is an excellent hobby to pursue.

Astronomers used three of NASA's Great Observatories to capture this multiwavelength image showing galaxy cluster IDCS J1426.5+3508. It includes X-rays recorded by the Chandra X-ray Observatory in blue, visible light observed by the Hubble Space Telescope in green, and infrared light from the Spitzer Space Telescope in red. This rare galaxy cluster has important implications for understanding how these megastructures formed and evolved early in the universe.

How Astronomers Time Travel

Let’s add another item to your travel bucket list: the early universe! You don’t need the type of time machine you see in sci-fi movies, and you don’t have to worry about getting trapped in the past. You don’t even need to leave the comfort of your home! All you need is a powerful space-based telescope.

But let’s start small and work our way up to the farthest reaches of space. We’ll explain how it all works along the way.

This animation illustrates how fast light travels between Earth and the Moon. The farther light has to travel, the more noticeable its speed limit becomes.

The speed of light is superfast, but it isn’t infinite. It travels at about 186,000 miles (300 million meters) per second. That means that it takes time for the light from any object to reach our eyes. The farther it is, the more time it takes.

You can see nearby things basically in real time because the light travel time isn’t long enough to make a difference. Even if an object is 100 miles (161 kilometers) away, it takes just 0.0005 seconds for light to travel that far. But on astronomical scales, the effects become noticeable.

This infographic shows how long it takes light to travel to different planets in our solar system.

Within our solar system, light’s speed limit means it can take a while to communicate back and forth between spacecraft and ground stations on Earth. We see the Moon, Sun, and planets as they were slightly in the past, but it's not usually far enough back to be scientifically interesting.

As we peer farther out into our galaxy, we use light-years to talk about distances. Smaller units like miles or kilometers would be too overwhelming and we’d lose a sense of their meaning. One light-year – the distance light travels in a year – is nearly 6 trillion miles (9.5 trillion kilometers). And that’s just a tiny baby step into the cosmos.

youtube

The Sun’s closest neighboring star, Proxima Centauri, is 4.2 light-years away. That means we see it as it was about four years ago. Betelgeuse, a more distant (and more volatile) stellar neighbor, is around 700 light-years away. Because of light’s lag time, astronomers don’t know for sure whether this supergiant star is still there! It may have already blasted itself apart in a supernova explosion – but it probably has another 10,000 years or more to go.

What looks much like craggy mountains on a moonlit evening is actually the edge of a nearby, young, star-forming region NGC 3324 in the Carina Nebula. Captured in infrared light by the Near-Infrared Camera (NIRCam) on NASA’s James Webb Space Telescope, this image reveals previously obscured areas of star birth.

The Carina Nebula clocks in at 7,500 light-years away, which means the light we receive from it today began its journey about 3,000 years before the pyramids of Giza in Egypt were built! Many new stars there have undoubtedly been born by now, but their light may not reach Earth for thousands of years.

An artist’s concept of our Milky Way galaxy, with rough locations for the Sun and Carina nebula marked.

If we zoom way out, you can see that 7,500 light-years away is still pretty much within our neighborhood. Let’s look further back in time…

This stunning image by the NASA/ESA Hubble Space Telescope features the spiral galaxy NGC 5643. Looking this good isn’t easy; 30 different exposures, for a total of nine hours of observation time, together with Hubble’s high resolution and clarity, were needed to produce an image of such exquisite detail and beauty.

Peering outside our Milky Way galaxy transports us much further into the past. The Andromeda galaxy, our nearest large galactic neighbor, is about 2.5 million light-years away. And that’s still pretty close, as far as the universe goes. The image above shows the spiral galaxy NGC 5643, which is about 60 million light-years away! That means we see it as it was about 60 million years ago.

As telescopes look deeper into the universe, they capture snapshots in time from different cosmic eras. Astronomers can stitch those snapshots together to unravel things like galaxy evolution. The closest ones are more mature; we see them nearly as they truly are in the present day because their light doesn’t have to travel as far to reach us. We can’t rewind those galaxies (or our own), but we can get clues about how they likely developed. Looking at galaxies that are farther and farther away means seeing these star cities in ever earlier stages of development.

youtube

The farthest galaxies we can see are both old and young. They’re billions of years old now, and the light we receive from them is ancient since it took so long to traverse the cosmos. But since their light was emitted when the galaxies were young, it gives us a view of their infancy.

This animation is an artist’s concept of the big bang, with representations of the early universe and its expansion.

Comparing how fast objects at different distances are moving away opened up the biggest mystery in modern astronomy: cosmic acceleration. The universe was already expanding as a result of the big bang, but astronomers expected it to slow down over time. Instead, it’s speeding up!

The universe’s expansion makes it tricky to talk about the distances of the farthest objects. We often use lookback time, which is the amount of time it took for an object’s light to reach us. That’s simpler than using a literal distance, because an object that was 10 billion light-years away when it emitted the light we received from it would actually be more than 16 billion light-years away right now, due to the expansion of space. We can even see objects that are presently over 30 billion light-years from Earth, even though the universe is only about 14 billion years old.

This James Webb Space Telescope image shines with the light from galaxies that are more than 13.4 billion years old, dating back to less than 400 million years after the big bang.

Our James Webb Space Telescope has helped us time travel back more than 13.4 billion years, to when the universe was less than 400 million years old. When our Nancy Grace Roman Space Telescope launches in a few years, astronomers will pair its vast view of space with Webb’s zooming capabilities to study the early universe in better ways than ever before. And don’t worry – these telescopes will make plenty of pit stops along the way at other exciting cosmic destinations across space and time.

Learn more about the exciting science Roman will investigate on X and Facebook.

The Red Planet MARS 🔴|| Reddish Colour Surface|| The Brightest Object in Earth's Sky

Want to Watch the video of The Red Planet MARS 🔴

Go to my youtube channel @InfinityASTRONOMERICA

It's a New Youtube Channel so, Please Subscribe my channel.

About the Video:

Mars is the fourth planet and the furthest terrestrial planet from the Sun. The reddish color of its surface is due to finely grained iron(III) oxide dust in the soil, giving it the nickname "the Red Planet". Mars's radius is second smallest among the planets in the Solar System at 3,389.5 km (2,106 mi). The Martian dichotomy is visible on the surface: on average, the terrain on Mars's northern hemisphere is flatter and lower than its southern hemisphere. Mars has a thin atmosphere made primarily of carbon dioxide and two irregularly shaped natural satellites: Phobos and Deimos.

Have a gold star...

I swear, I started this as a wholesome innocent comment on how when Crowley has to think of a prize, after 6000+ years, his sweet head still goes to stars as the ultimate symbol of something beautiful and cherished.

But then I was struck by something: sarcasm.

Both times, when he tells someone to "have a gold star," he doesn't say it with a tone of affectionate irony, like the cool-but-sweet uncle with a rough personality but a soft heart. He says it with a tone of bitter sarcasm, of painful disenchantment.

Because it's not a prize that he is offering; it's a sop, a cruel joke-gift, something that will get you excited at first just because you have a stupid, naive, innocent soul, and you will later realize that it means nothing to the one who assigned it to you, and that they are ready to take it away whenever they want, while the rest of the world laughs at your ridiculous gullibility.

Because this is what stars were for him.

They were his beloved, exciting creation. The star-factory nebula was his cherished task, assigned to him by God, and he believed that it was meant to be a thing of beauty and splendor, and hold value in the grand scheme of the universe... only to discover, immediately after he created it, that it was never intended to have any value at all. It meant nothing to God. It wasn't even planned to last enough to fullfill its purpose. It was a joke, a cruel prank.

The stars were God's bad pun of giving angel!Crowley something to do, and love, and have hope and expectations for, and then taking it away. Revealing that it was just a shiny piece of gold cardstock that only a simpleton could consider valuable. Of course he can only say "have a gold star" as a dry snarky sarcastic comment on someone who thinks they have achieved something meaningful when it's actually nothing. Be it the Them defeating the Four Horsemen. Be it Muriel being noticed by the Metatron.

Great, sure, have a gold star, be all excited and squealing with happiness, it will turn into ashes before you even know it.

I am not sure that Crowley's snake eyes were ever intended to signal that he cannot see the stars because snakes have bad vision (even ignoring the zoological fact that they are sensitive to UV light though, so they should still see astronomical objects, in the book it says that demons must be able to see at night, and that's why Crowley doesn't need to turn on the lights on the Bentley), but for sure the Fall and Heaven's cruelty has ruined the stars for him, in a way.

Now, in his mind, they are the ultimate symbol of delusion, of naivety, of foolishly investing your love and passion and hopes in something, of stupidly ignoring that the things you cherish will be ruined or taken away from you or leave you on their own accord.

That's also why Aziraphale's "nothing lasts forever" cuts him so deep. That's why his "no... no, I dont' suppose it does" sounds so much like a truth that he is remembering instead of one that he has jsut discovered.

Here you go, you did it again, you thought you had something significant and instead it was just like your stars, you should have known that whenever you find something beautiful it's just a matter of time before you lose it, you shouldn't get too attached.

In s1e6 he says it to the Them, in s2e6 he says it to Muriel. I do hope that in s3e6 he will get the chance to say it again, but this time it will be honest and out of joy, because whatever is going to happen will make him able again to believe that you can be happy, and can hold onto the good things that you love. You can have all the gold stars, for real. They don't always have to disappear and leave you in pain. They can stay with you.

#he's still the starmaker deep down #have a gold star #good omens #good omens 2 #go2 #crowley #aziraphale #good omens thoughts #go2 spoilers #go 2 speculation #good omens 2 spoilers
