“We want our sound to go into the soul of the audience, and see if it can awaken some little thing in their minds… ‘Cause there are so many sleeping people.”
One of the greatest challenges in music is to take a great original song and cover it, adding your own twist or flavor, and produce something that’s even better. Most of you have heard the Four Tops’ song It’s the Same Old Song, which has its own interesting story.
Hubble is great for looking at nearby objects in the Universe in visible light, while Chandra looks in X-ray light. Separately, they each give us beautiful, informative images.
For example, here’s Hubble’s view deep inside the Eagle Nebula, looking at a feature that’s now known as the Pillars of Creation. (Although, interestingly enough, a nearby supernova may have already destroyed them.)
In a galaxy, when large regions of gas start to collapse, they form new stars! But it’s very difficult to see these new stars, because the light is blocked by, well, the large amounts of gas surrounding these new stars!
At least, the visible light is.
But young, big, hot stars also emit X-ray light. And that’s the sort of thing that Chandra eats for breakfast.
Lo and behold, there are a bunch of hot, young stars in this region. This means that these pillars are signposts that new stars form here.
But this is about covers, so what happens when we overlay these images atop one another?
We learn that most of the stars have already formed, and have done so outside of the pillars! Not something we would have necessarily expected, but something that we learned from the original visible image and the X-ray cover, together!
So have a great weekend, and I’ll see you all next week!
