When it comes to the Universe, physicists say things like: it originated in a Big Bang, it’s isotropic (or the same in all directions), and it’s homogeneous (the same everywhere), save for the effects of cosmic evolution. In every direction we look, we see galaxies expanding away from us, with the expansion rate increasing the…

“Deep into that darkness peering, long I stood there, wondering, fearing, doubting, dreaming dreams no mortal ever dared to dream before.” –Edgar Allan Poe Thanks to the Hubble Space Telescope, we’ve learned for a certainty that the black abyss of empty space isn’t really so empty. Far beyond what we can perceive with our naked…

“People get cranky when you burst their bubble. Over time, advances in astronomy have relentlessly reinforced the utter insignificance of Earth on a celestial scale.” –Nathan Myhrvold When new stars form from a collapsing molecular cloud, the hottest, bluest, brightest stars emit high-energy ultraviolet radiation. This evaporates, ionizes and pushes the gas outwards, creating a bubble…

“No distance of place or lapse of time can lessen the friendship of those who are thoroughly persuaded of each other’s worth.” –Robert Southey You might think that, when it comes to finding the most distant objects in the Universe, all we need is a good telescope, to leave the shutter open, and wait. As…

“It is by going down into the abyss that we recover the treasures of life. Where you stumble, there lies your treasure.” –Joseph Campbell Imagine you just stared into darkness, collecting every photon of light that came by. What would you wind up seeing? The Hubble Space Telescope has done this many times, creating the…

“But I see it differently now. There has to be a middle. Without it, nothing can truly be whole. Because it is not just the space between, but also what holds everything together.” –Sarah Dessen Sure, the Hubble Space Telescope gives us unparalleled views of our Universe. We can even use it — with its…

“The voyage of discovery is not in seeking new landscapes but in having new eyes.” -Marcel Proust As another fine week comes to a close at Starts With A Bang, let’s take a look back at all the topics we’ve taken on: Where did light first come from? (for Ask Ethan), Zooming into a fractal (for our Weekend Diversion),…

“Silently, one by one, in the infinite meadows of heaven, Blossomed the lovely stars, the forget-me-nots of the angels.” –Longfellow The cosmic microwave background is a thing of beauty, as not only does its uniform, cold temperature reveal a hot, dense past that began with the hot Big Bang, but its fluctuations reveal a pattern…

Hubble’s Deepest Look (Synopsis)

When you think of the Hubble Space Telescope, perhaps you think of what’s touted as its most major feat of all: peering off into deep, dark space, collecting light, and discovering the plethora of distant galaxies laying billions of light years beyond our own. It’s a spectacular sight and a spectacular story, and it’s allowed…

“That I learned even as a three year-old that I see this world that is really a mess and I learned to say, ‘This is not me. I am not the one that is messed up. It is out there.’” –Story Musgrave It was 25 years ago this year that the Hubble Space Telescope first…
