How awesome is this?! via Nasa.gov: Astronomers using data from NASA’s Hubble Space Telescope and ground observation have found an unlikely object in an improbable place — a monster black hole…
Reads like an extreme case of global warming … unlike what’s going to happen to Earth is around 5 billion years when the Sun expands enough to consume most of the inner Solar System (one theory), this planet is moving towards its star. The poor thing only has around 10 million years left.
Man, the Hubble keeps finding cool stuff.
So the clock’s ticking (in astronomical terms), it’s time for the one scientist over there who no one is listening to about this planet’s impending destruction to rocket his infant son off into the universe … not too far from Earth. Reports the Hubble Site News Center…

Amazing to consider what we didn’t know less than a hundred years ago. Via PBS:
On December 30, 1924, Hubble announced the discovery of a Cepheid, or variable star, in the Andromeda Nebulae. Since the work of Henrietta Leavitt had made it possible to calculate the distance to Cepheids, he calculated that this Cepheid was much further away than anyone had thought and that therefore the nebulae was not a gaseous cloud inside our galaxy, like so many nebulae, but in fact, a galaxy of stars just like the Milky Way. Only much further away. Until now, people believed that the only thing existing ouside the Milky Way were the Magellanic Clouds. The Universe was much bigger than had been previously presumed.

Here’s a video of Hubble’s work found on YouTube:
Phil Plait writes on Bad Astronomy:
Holy Haleakala! This picture is incredible. They pointed Hubble at a fairly empty region of space, one where very few stars are seen. Then they unleashed the new Wide Field Camera 3 (called WFC3 for short) on it, taking images in infrared wavelengths just outside what the human eye can see … and they let it stare at that spot for a solid 48 hours.
The result? This picture, showing galaxies flippin’ everywhere, some seen a mere 600 million years after the Big Bang itself. Because the Universe is expanding, distant galaxies appear to recede from us, and their light gets stretched out. This Doppler Effect — the same thing that makes the sound of a car engine drop in pitch when it passes you at high speed — changes the colors we see from these far-flung galaxies, so their ultraviolet light, for example, gets stretched into visible and even infrared wavelengths. What you are seeing here is actually more energetic light emitted by galaxies that’s lost energy traveling across the expanding Universe, so by the time it gets here it’s infrared.
So the colors are not “real” in this image; they’ve been translated into red, green, and blue so we can see them. The reddest objects in the image are most likely the farthest away, and may be as much as 13 billion light years away. Thirteen billion. With a B.
