Thick dust and blinding starlight have long obscured our vision into the mysterious inner regions of the galactic center. And yet, the clues have been piling up, that something important, something strange is going on in there. Astronomers tracking stars in the center of the galaxy have found the best proof to date that black holes exist. Now, they are shooting for the first direct image of a black hole. From a distance, our galaxy would look something like this. A flat spiral, some 100,000 light years across, with pockets of gas, clouds of dust, and about 400 billion stars rotating around the galaxy's center. That center -- bulging up and out of the galactic disk -- is tightly packed with stars. Thick dust and blinding starlight have long obscured our vision into the mysterious inner regions of this so-called "bulge." And yet, the clues have been piling up, that something important...something strange... is going on in there. The first to take notice was the physicist Karl Jansky back in the 1930s. He was asked by his employer, Bell Telephone Labs, to investigate sources of static that might interfere with what it saw as the killer app of its time... radio voice transmissions. Using this ungainly radio receiver... Jansky methodically scanned the airwaves. He documented thunderstorms, near and far... and another signal he could not explain. It sounded like steam -- a hiss of radio noise. Jansky narrowed it to a spot in the constellation of Sagittarius, in the direction of the center of the galaxy. Located within a larger pattern of radio emissions... ... Jansky's sighting would become known as Sagittarius A. The word of Jansky's finding got out. He assured the public that it was not aliens seeking contact. But that's just about all anyone could say... for over three decades. Then Erik Becklin got on the case. Becklin is one of those rare researchers whose curiosity and determination push our understanding to a whole new level. It was the 1960's and astronomy, like society, was in a period of ferment. Startling new observations were being made... and new interpretations were in the air. Quasars had just been discovered... extremely bright beacons of light from deep space. Were they coming from the centers of distant galaxies? And what powerful objects were generating them? To study an event at the center of a galaxy, you have locate it. Young Becklin first took aim at our neighboring galaxy, Andromeda. In ultraviolet light, you can see a dense glow in the middle. Becklin found the point where the light reaches peak intensity... and marked it as the Center. From our orientation in space, all of the Andromeda galaxy is in full view. But our galaxy is a different story. We live inside it, of course. Becklin had to find a way to see through all the dust and gas that obscure our line of sight into the center. So he went to a military contractor... ...and obtained a device that reads infrared light... whose wavelengths are similar to the distances between particles in a dust cloud, allowing them to move right through. Becklin began measuring the brightness of the light as it rose to a peak... marking the location of the galactic center. Pinpointing this site would now allow astronomers to begin probing for details with a new generation of powerful telescopes... to peer into the bright lights... the forbidden zones... deep in the heart of the Milky Way. Becklin wasn't the only astronomer interested in the galactic center. Reinhardt Genzel, and a team based at the Max Planck Institute for Extraterrestrial Physics in Germany, began a similar campaign in 1990... from the New Technology Telescope in the mountains of Chile. A few years later, in 1993, high atop Hawaii's Mauna Kea volcano... Eric Becklin and colleagues, including Andrea Ghez, began using the newly christened Keck Telescope. The American and German groups shared the same goal... to pinpoint the precise location of Sagittarius A, and find out what it is. Because the object is too small to see... at 26,000 light years away... they would study it by tracking the orbits of stars around it. Even seeing them would take the sensitivity of Keck's wide aperture; an instrument powerful enough to detect a single candle flame at the distance of the moon... Meanwhile, using a similar technique, astronomers had focused the new Hubble Space Telescope on a different galaxy... a giant elliptical cloud of nearly a billion stars, lying some 50 million light years away called M87.

Cosmology, the study of the universe as a whole, has been turned on its head by a stunning discovery that the universe is flying apart in all directions at an ever-increasing rate. Is the universe bursting at the seams? Or is nature somehow fooling us? The astronomers whose data revealed this accelerating universe have been awarded the Nobel Prize for Physics. And yet, since 1998, when the discovery was first announced, scientists have struggled to come to grips with a mysterious presence that now appears to control the future of the cosmos: dark energy. On remote mountaintops around the world, major astronomical centers hum along, with state of the art digital sensors, computers, air conditioning, infrastructure, and motors to turn the giant telescopes. Deep in Chile's Atacama desert, the Paranal Observatory is an astronomical Mecca. This facility draws two megawatts of power, enough for around two thousand homes. What astronomers get for all this is photons, tiny mass-less particles of light. They stream in from across time and space by the trillions from nearby sources, down to one or two per second from objects at the edge of the visible universe. In this age of precision astronomy, observers have been studying the properties of these particles, to find clues to how stars live and die, how galaxies form, how black holes grow, and more. But for all we've learned, we are finding out just how much still eludes our grasp, how short our efforts to understand the workings of the universe still fall. A hundred years ago, most astronomers believed the universe consisted of a grand disk, the Milky Way. They saw stars, like our own sun, moving around it amid giant regions of dust and luminous gas. The overall size and shape of this "island universe" appeared static and unchanging. That view posed a challenge to Albert Einstein, who sought to explore the role that gravity, a dynamic force, plays in the universe as a whole. There is a now legendary story in which Einstein tried to show why the gravity of all the stars and gas out there didn't simply cause the universe to collapse into a heap. He reasoned that there must be some repulsive force that countered gravity and held the Universe up. He called this force the "cosmological constant." Represented in his equations by the Greek letter Lambda, it's often referred to as a fudge factor. In 1916, the idea seemed reasonable. The Dutch physicist Willem de Sitter solved Einstein's equations with a cosmological constant, lending support to the idea of a static universe. Now enter the American astronomer, Vesto Slipher. Working at the Lowell Observatory in Arizona, he examined a series of fuzzy patches in the sky called spiral nebulae, what we know as galaxies. He found that their light was slightly shifted in color. It's similar to the way a siren distorts, as an ambulance races past us. If an object is moving toward Earth, the wavelength of its light is compressed, making it bluer. If it's moving away, the light gets stretched out, making it redder. 12 of the 15 nebulae that Slipher examined were red-shifted, a sign they are racing away from us. Edwin Hubble, a young astronomer, went in for a closer look. Using the giant new Hooker telescope in Southern California, he scoured the nebulae for a type of pulsating star, called a Cepheid. The rate at which their light rises and falls is an indicator of their intrinsic brightness. By measuring their apparent brightness, Hubble could calculate the distance to their host galaxies. Combining distances with redshifts, he found that the farther away these spirals are, the faster they are moving away from us. This relationship, called the Hubble Constant, showed that the universe is not static, but expanding. Einstein acknowledged the breakthrough, and admitted that his famous fudge factor was the greatest blunder of his career.

[View \| Download]	The Largest Black Holes in the Universe How big can they get? What's the largest so far detected? Where does an 18 billion solar mass black hole hide? We've never seen them directly... yet we know they are there... Lurking within dense star clusters... Or wandering the dust lanes of the galaxy.... Where they prey on stars... Or swallow planets whole. Our Milky Way may harbor millions of these black holes... the ultra dense remnants of dead stars. But now, in the universe far beyond our galaxy, there's evidence of something even more ominous... A breed of black holes that have reached incomprehensible size and destructive power. It has taken a new era in astronomy to find them... High-tech instruments in space tuned to sense high-energy forms of light -- x-rays and gamma rays -- that are invisible to our eyes. New precision telescopes equipped with technologies that allow them to cancel out the blurring effects of the atmosphere... and see to the far reaches of the universe. Peering into distant galaxies, astronomers are now finding evidence that space and time can be shattered by eruptions so vast they boggle the mind. We are just beginning to understand the impact these outbursts have had on the universe around us. That understanding recently took a leap forward. A team operating at the Subaru Observatory atop Hawaii's Mauna Kea volcano looked out to one of the deepest reaches of the universe... And captured a beam of light that had taken nearly 13 billion years to reach us. It was a messenger from a time not long after the universe was born. They focused on an object known as a quasar... short for "quasi-stellar radio source." It offered a stunning surprise... A tiny region in its center is so bright that astronomers believe it's light is coming from a single object at least a billion times the mass of our sun... Inside this brilliant beacon, space suddenly turns dark... as it's literally swallowed by a giant black hole. As strange as they may seem, even huge black holes like these are thought to be products of the familiar universe of stars and gravity. They get their start in rare types of large stars... at least ten times the mass of our sun. These giants burn hot and fast... and die young. The star is a cosmic pressure-cooker. In its core, the crush of gravity produces such intense heat that atoms are stripped and rearranged. Lighter elements like hydrogen and helium fuse together to form heavier ones like calcium, oxygen, silicon, and finally iron. When enough iron accumulates in the core of the star, it begins to collapse under its own weight. That can send a shock wave racing outward... Literally blowing the star apart:... a supernova. At the moment the star dies, if enough matter falls into its core, it collapses to a point, forming a black hole. Intense gravitational forces surround that point with a dark sphere... the event horizon... beyond which nothing, not even light, can escape. That's how an average-size black hole forms. What about a monster the size of the Subaru quasar? Recent discoveries about the rapid rise of these giant black holes have led theorists to rethink their view of cosmic history.
