Skip to comments.Astronomy Picture of the Day -- Planck Maps the Microwave Background
Posted on 03/25/2013 5:00:35 PM PDT by SunkenCiv
Explanation: What is our universe made of? To help find out, ESA launched the Planck satellite to map, in unprecedented detail, slight temperature differences on the oldest surface known -- the background sky left billions of years ago when our universe first became transparent to light. Visible in all directions, this cosmic microwave background is a complex tapestry that could only show the hot and cold patterns observed were the universe to be composed of specific types of energy that evolved in specific ways. The results, reported last week, confirm again that most of our universe is mostly composed of mysterious and unfamiliar dark energy, and that even most of the remaining matter energy is strangely dark. Additionally, Planck data impressively peg the age of the universe at about 13.81 billion years, slightly older than that estimated by various other means including NASA's WMAP satellite, and the expansion rate at 67.3 (+/- 1.2) km/sec/Mpc, slightly lower than previous estimates. Some features of the above sky map remain unknown, such as why the temperature fluctuations seem to be slightly greater on one half of the sky than the other.

So that’s the universe? The entire universe?
Well their energy has been removed....from the caregully constructed picture.
The universe is an Easter Egg. I knew it.
Kinda looks like earth
The observable universe.
I thought it looked kinda like one of those color blindness charts.
Is there a 3D version on the web?
Unless my speculative joke is correct and the reason for certain very large apparent structures in the cosmos is due to our already having entered the event horizon of a black hole.
Washington DC must be tip of the funnel of matter spiraling in first!
So we're only seeing a part of the void surrounding the "Big Bang"?? Is that a veil beyond which we can never see, or will we eventually find a way to view the whole of the unknown universe?
The more we learn, the more we realise we don't know. Amazing. Thanks, SunkenCiv.
Kinda makes you feel like Lou Costello, doesn’t it? - “I don’t even know what I’m talkin’ about!”
