"The truth may be puzzling. It may take some work to grapple with. It may be counterintuitive. It may contradict deeply held prejudices. It may not be consonant with what we desperately want to be true. But our preferences do not determine what's true.
We have a method, and that method helps us to reach not absolute truth, only asymptotic approaches to the truth - never there, just closer and closer, always finding vast new oceans of undiscovered possibilities. Cleverly designed experiments are the key."

It's the Milky Way as you've never seen it before! Two and a half billion infrared pixels are exposing our own Galaxy in this new image from NASA's Spitzer Space Telescope! Science is all about getting the big picture, but some pictures are definitely bigger than others.
You may have used your computer to make a large panorama yourself by stitching together a few shots from your camera. Depending on the camera the final picture may contain ten or twenty million pixels. Now can you imagine taking over 800,000 images and combining them into a single two-and-a-half billion pixel image?
Two teams of astronomers have not only imagined it... they've used NASA's Spitzer Space Telescope to make one. And it's online for everyone to explore. Over 50 astronomers have worked on this massive project since the Spitzer mission began. This image combines data from two different legacy projects known as GLIMPSE, headed up by Dr Ed Churchwell and MIPSGAL, led by Dr. Sean Carey.
The picture covers an area of sky as wide as your finger held out at arm's length, and as long as your open arms. That's about 2 by 130 degrees. Though it sounds like a pretty small slice of the sky, it actually captures half of our entire galaxy! Our sun sits a ways out from the Galactic center, so a 130-degree arc takes in most of its area.
And our Milky Way is very thin compared to its diameter, a lot like a CD. So even a 2° wide scan includes most of its disk. The rest of the stars that fill the sky are actually very close to us, filling just a tiny fraction of the disk right around our sun.
A space image this big takes a lot of space to show off. Spitzer unveiled this giant banner, 4 feet tall and 180 feet long, at the 2008 summer meeting of the American Astronomical Society in St. Louis! Since then it's been on display at the Adler Planetarium in Chicago, and at the Griffith Observatory in Los Angeles.
The GLIMPSE part of the survey includes the shorter infrared wavelengths. At 3.6 and 4.5 microns we see blue stars that, in visible light, are completely hidden by dust. Carbon-based dust molecules show up at 8 microns, represented as green. MIPSGAL contributes the 24-micron component, rendered as red. This is the warm thermal glow from dust clouds heated by nearby stars.
Together these observations give us a pretty complete view of stellar evolution, beginning to end, across our Galaxy. These ubiquitous dark filaments are dust clouds so dense they're opaque even in the infrared. They're dense enough to trigger gravitational collapse and form new stars.
The red dots seen along these filaments are embedded protostars only barely seen at the longest, most transparent infrared wavelengths. Once the stars are fully formed and glowing from the heat of nuclear fusion, they illuminate, warm, and disrupt the surrounding dust, creating these dramatic structures near and far.
The stars eventually drift beyond their birthplaces mixing among their older cousins. This diffuse blue glow shows us the overall distribution of stars throughout the galaxy. Eventually the most massive stars die in supernova explosions. We can see their expanding shock waves rich in newly forged heavy elements that will help form the next generation of dust and stars.
The GLIMPSE-MIPSGAL image is truly a pictorial guide to the past, present, and future of stars throughout our home galaxy. Astronomers will study the data for many years to come, and the observations will be a roadmap to guide future infrared observatories.
If you'd like to explore Spitzer's Milky Way yourself, all 2.5 gigapixels are available on our website. You can download the whole thing in segments, or use one of several web viewers that let you pan and zoom through the image interactively. Take a look; you might find something that no one else has seen!

Total Solar Eclipse across America today! (April 8th, 2024)
Bullshit, "in the Universe".
Truly the heavens declare the glory of God and the earth shows his handiwork. It says God weighs the oceans in the palm of His hands. When he spoke forth light in Genesis 1, he was creating the bubble of time in which our universe exists. Since He exists outside of time, eventually, that's where we are all going to end up. Jesus came to open the door to eternity for us. Don't consider yourself too good for his gift, or not good enough. It cost his life but He did it for me and for you. Open your heart and receive it. John 3:3-16🫶
Actually sun in a few more billion years the sun will KELT_9b as not in our solar system but 670 light years away from earth. KELT_9b is a hot planet which is very big and the chance of you surviving is 0 percent since the heat is about 7,800 degrees Fahrenheit or 4,300 degrees Celsius. And since im in 4th grade in 3rd I learned that nasa is going to get everyone of us to mars in 2030 their doing research right now. Edit: sun is going to destroy earth in a few more billion years😢 Earth was the best planet to us or to me in my opinion.😢 Search this in safari or anymore like that if you don’t believe me or if you don’t know what KELT_9b is..😢
Where is Pluto??
This is a testament to the unfathomable might of God❤
And God created all of it, keeps everything in balance, and powers it all. God is so great and powerful!
Actually Gods (Elohim) is plural in the bible. Hebrew and plural the suffix im........
@@fernandoluiznewcastle772 You are right. Elohim is plural. God is made up of three persons (one being). The Bible says that God is one in many places. _Deuteronomy 6:4 “Hear, O Israel: The Lord our God, the Lord is one._
Yeah prove your myths This is a science channel, not religious bullshit

No
Give all glory to God. Give all glory Jesus Christ God in the flesh. Glory to the holy Spirit. One God three different persons. #1 Psalms 8:3-4 when I look at your heavens the work of your fingers the moon and the Stars would you have set in place what is man that your mind full of him and his son of man that you care for him.

Ok please genuinely i want to know how the fuck these things take pictures of shit that far away without something getting in the way…
This makes me realize how small we are, yet so loved by the Creator of it all ❤️
Was the expansion spontaneous or was there a trigger? Prior to the expansion was space a perfect vacuum?
I remember watching this when I was first getting into astronomy. It’s been roughly six years since I first watched this video (I think). Dang, time flies.
Wow... that is the only word to describe this.
the biggest stars are V838. HD 143183. UY Scuti. WOH G64. VV Cephei. V354 Cephei. Stephenson 2-18. KW Sagittarii. VX Sagittarii. Westerlund 1-26. RW Cephei. Betelgeuse.
Stephenson 2-18
Yeah it's the biggest but I think at this time when this video was released I think Stephenson 2-18 wasn't discovered
Give a WAYE
So big
God the vast cosmos is just. Breath taking..
