Black holes are some of the most elusive objects in the Universe. They can form when a massive star collapses under its own weight. Because they are very dense, the gravitational pull of black holes is so strong that nothing can escape, not even light. Thus they have long remained black and mysterious.

But now, thanks to ESA's and NASA's X-ray observatories, XMM-Newton and Chandra, astronomers have a much clearer picture of where black holes are and what they can actually do. And that can be quite dramatic!

Observations of RXJ 12 42 11 have provided evidence of how a giant black hole can tear apart and swallow a star, as explained by Dr Stefanie Komossa of Max Planck Institute in Munich.

Every other Wednesday we present a new video, so join us to see the truth laid bare...

Somewhere in our galaxy, at some time in the future, a spacecraft from Earth will encounter the most dangerous object in the Universe. A stunning visual journey into black holes, their structure and their creation.

A black hole is a geometrically defined region of spacetime exhibiting such strong gravitational effects that nothing, including particles and electromagnetic radiation such as light, can escape from inside it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

Supermassive Black Holes or Their Galaxies? Which Came First?

Every time astronomers look farther out in the Universe, they discover new mysteries. These mysteries require all new tools and techniques to understand. These mysteries lead to more mysteries. What I’m saying is that it’s mystery turtles all the way down.

One of the most fascinating is the discovery of quasars, understanding what they are, and the unveiling of an even deeper mystery, where do they come from?

As always, I’m getting ahead of myself, so first, let’s go back and talk about the discovery of quasars.

Back in the 1950s, astronomers scanned the skies using radio telescopes, and found a class of bizarre objects in the distant Universe. They were very bright, and incredibly far away; hundreds of millions or even billion of light-years away. The first ones were discovered in the radio spectrum, but over time, astronomers found even more blazing in the visible spectrum.

The astronomer Hong-Yee Chiu coined the term “quasar”, which stood for quasi-stellar object. They were like stars, shining from a single point source, but they clearly weren’t stars, blazing with more radiation than an entire galaxy.

Over the decades, astronomers puzzled out the nature of quasars, learning that they were actually black holes, actively feeding and blasting out radiation, visible billions of light-years away.

But they weren’t the stellar mass black holes, which were known to be from the death of giant stars. These were supermassive black holes, with millions or even billions of times the mass of the Sun.

As far back as the 1970s, astronomers considered the possibility that there might be these supermassive black holes at the heart of many other galaxies, even the Milky Way.

In 1974, astronomers discovered a radio source at the center of the Milky Way emitting radiation. It was titled Sagittarius A*, with an asterisk that stands for “exciting”, well, in the “excited atoms” perspective.

This would match the emissions of a supermassive black hole that wasn’t actively feeding on material. Our own galaxy could have been a quasar in the past, or in the future, but right now, the black hole was mostly silent, apart from this subtle radiation.

Astronomers needed to be certain, so they performed a detailed survey of the very center of the Milky Way in the infrared spectrum, which allowed them to see through the gas and dust that obscures the core in visible light.

They discovered a group of stars orbiting Sagittarius A-star, like comets orbiting the Sun. Only a black hole with millions of times the mass of the Sun could provide the kind of gravitational anchor to whip these stars around in such bizarre orbits.

Further surveys found a supermassive black hole at the heart of the Andromeda Galaxy, in fact, it appears as if these monsters are at the center of almost every galaxy in the Universe.

But how did they form? Where did they come from? Did the galaxy form first, and cause the black hole to form at the middle, or did the black hole form, and build up a galaxy around them?

All objects exert an attractive gravitational force which depends on their mass. Now, imagine an object with a very large mass which is concentrated into such a small volume that the gravitational field generated is powerful enough to prevent anything from escaping its clutches – even light. This bizarre concept intrigues everyone, in particular physicists who theorise about the nature of matter, space and time, and astrophysicists who look for real black holes out in space. Their study brings together the big ideas in fundamental science: Einstein’s theory of gravity – general relativity; the theory of the very small – quantum mechanics; and the origin and evolution of the universe – cosmology. In recent years scientists have sought the answers to questions such as does a black hole have a temperature? What exactly happens when an object falls into a black hole? How many black holes are there in our galaxy? What is the role of black holes in galaxy evolution?

Fifty years ago, the discovery of quasars transformed astronomy. Studies of quasars and other active galactic nuclei still are a major, vibrant, and developing part of astronomy, astrophysics, and cosmology. This year we celebrate the 50th anniversary of this discovery, and honor Maarten Schmidt, whose insight into the nature of quasar spectra was a decisive milestone in the rise of this new field of research, in addition to his continued contributions ever since.

The meeting consisted of invited talks only, covering various aspects of the history and the current state of quasar research.

Hubble Black Hole Probe

From HubbleCast. For centuries, scientists imagined objects so heavy and dense that their gravity might be strong enough to pull anything in, including light. They would be, quite literally, a black hole in space. But it's only in the past few decades that astronomers have conclusively proved their existence. Today, Hubble lets scientists measure the effects of black holes, make images of their surroundings and glean fascinating insights into the evolution of our cosmos.

In science fiction, black holes are often portrayed as some kind of menacing threat to the safety of the whole Universe, like giant vacuum cleaners that somehow suck up all of existence. Now, in this episode, we're going to separate the fiction from the facts and we're going to look at the real science behind black holes and how Hubble has contributed to it.

Black holes come in different sizes. We've had solid evidence for the smaller ones since the 1970s. These form when a huge star explodes at the end of its life. As the outer layers are blown away, the star's core collapses in on itself forming an incredibly dense ball. For instance, a black hole with the same mass as the Sun would have a radius of only a few kilometers.

Before Hubble was launched, astronomers had noticed that the centers of many galaxies were somehow much denser and brighter than they were expected to be. And so they speculated that there must be some kind of huge, massive objects lurking in the centers of these galaxies in order to provide the additional gravitational attraction.

Now, could these objects be supermassive black holes, that is, black holes which are millions or even billions of times more massive than the stellar ones? Or was there perhaps a simpler, less exotic explanation, like giant star clusters?

Fortunately, Hubble was on its way, along with a range of other high-tech telescopes. When the space telescope was being planned, the search for supermassive black holes was in fact one of its main objectives.

Some of Hubble's early observations in the 1990s were dedicated to these dense, bright galactic centers. Where ground-based telescopes were just seeing a sea of stars, Hubble was able to resolve the details.

In fact, around the very centers of these galaxies, Hubble discovered rotating discs of gas and dust.

When Hubble observed the disc at the center of a nearby galaxy, Messier 87, the astronomers saw that its color was not quite the same on both sides. One side was shifted towards blue and the other towards red, and this told the scientists that it must have been rotating very quickly.

This is because the wavelength of light is changed by the motion of an object emitting it. Think about how the pitch of an ambulance siren drops as it drives past you, because the sound waves are more spaced out as the vehicle moves away.

Similarly, if an object is moving towards you, the light's wavelength is squashed, making it bluer; if it's moving away, it's stretched, making it redder. This is also known as the Doppler effect.

So, by measuring how much the colours had shifted on either side of the disk, astronomers were able to determine its speed of rotation. And it turned out that this disk was spinning at a rate of hundreds of kilometers per second. This in turn allowed astronomers to deduce that, hidden at the very center, there must be some kind of object which was two to three billion times the mass of the Sun - and this was very likely a supermassive black hole.

Now, along with a lot of other observations, this was a key piece of evidence that led to the notion that there is a supermassive black hole lurking at the center of most, if not all, giant galaxies, including our own Milky Way.

Well, the science of black holes has moved along a lot since then. The mystery now isn't whether they exist, but why they behave in the strange ways they do.

For example, Hubble observations have helped to show that the mass of a supermassive black hole is closely related to the mass of its surrounding host galaxy. The bigger the black hole, the bigger the galaxy.

A supermassive black hole is pretty big, and it packs a lot of punch, but you've got to remember that compared to its host galaxy it's actually tiny. The region of space that is most obviously and most immediately influenced by a supermassive black hole is in fact about a million times smaller than its surrounding galaxy. That's about the same size difference as between this coin and a whole city. So it's pretty hard to think of any processes that would link the two in a long-lasting way.

So a big area in science just now is trying to find out what's going on here, and why the two are linked. Do black holes regulate the size of galaxies, or do galaxies regulate the size of black holes? Or is something altogether different happening?

Black Holes and Quasars - Documentary

Today most scientists believe that super massive black holes at the galactic centres are the engines that power the quasars. This films studies the size of quasars, super massive black holes, formation of quasars, radio waves from space objects, super novas, stars,
galaxies and more. Nice documentary on Black holes and quasars!
