Tag Archive: Black Hole

The latest on the happenings at the Center of the Galaxy!  This whole series started with the article stating that a gas cloud was heading toward the black hole known as Sag A* at the center of the Milky Way and what that might mean (The Event).

June 27, 2012

The latest video from  ESO with some interesting graphics and discussion and is an easy way to get an idea of what this series is about:

Video will show a graphic example of what they think is happening and some actual photos over time.

The important bit to remember! The ‘cloud’ is now travelling at 8 Mkph.  Almost twice as fast as what they said 6 months ago and it is accelerating (of course it is, it’s approaching a black hole).  And. they are back to saying it is just gas, not a solar system.  But also, they say that no one knows what will happen next, certainly true.

It is now 36 light hours from the center (40,000,000,000 km, or 5000 hours, or 208 days, or about 6-7 months, which will be January/February 2013 at its current speed) .  It’s reasonable to assume it will only accelerate from this point forward. IT IS SPEEDING UP, so it will be there SOONER than this.

See UNIVERSE TODAY for a description of the information in the above video.


  • This thing is happening. RIGHT NOW.
  • It will reach it’s peak (nearest approach, or perigee), in January 2013 OR SOONER.
  • It is MASSIVE and it will do something both visible and X-RAY spectrums. MINIMUM.
  • You will see it, and hear about it in the coming months.

Wait, what will happen again if this occurs?  Watch this for a ‘simple’ explanation.

A short video produced by NASA / Harvard  Chandra observatory explaining how we get X-Ray flares from SagA* when any asteroid greater than 6 miles wide gets sucked in.  They estimate that there are TRILLIONS of them circling the black hole.

How stuff falls into the black hole.

I would expect just a ‘few’ of these asteroids and comets will tag along for the ride, wouldn’t you?

First light image for NuStar space mission

“With the successful “first light” images, the mission will begin its exploration of the most elusive and energetic black holes — as well as other areas of extreme physics in our cosmos — to help in our understanding of the structure of the universe.

NuStar is a brand new satellite that was sent up to be an X-RAY telescope.  Since we know what it does and that SagA* will be putting out some serious X-RAYS (see video above), then we must assume that they will look for them.  They don’t say that in this article, but you can bet that they will.  I am sue our first updates on this event will be from this satellite.

March 16, 2009

A truly dark way to look at this information:  This youtube poster thought that the star 14 Sgr would be the catalyst of some material exchange at the black hole at the center of the Galaxy.  However, It is 2 light years from the galaxy core when it is at its perigee(closest) but that happens in 2017, not 2012 as he stated back in 2009.  So he is wrong about that.  This video was posted LONG before the information above was available and the video’s postulation that this star would be a catalyst was wrong, but, the idea is the same and the  observed data of the time is still correct.  The video shows many examples of galactic cores and how they behave (sometimes).

A short video done in 2009. There is more information here, but what we see is that the information (and/or worry) has been around a long time. This time, we actually KNOW something is approaching the black hole.


The scary stuff starts about 3:50 showing how energy bursts for black holes, the model for what happens when matter falls into a black hole.  Don’t think it can’t happen?, or for that matter, the effects even reach us?

Watch this video of the effects of a SINGLE STAR (right next to SgrA*) that created a super burst in 2004 and its effects on earth.

April 3, 2009 of an event that occurred December 17, 2004

The explosion that was halfway across the galaxy packed so much power it briefly altered Earth’s upper atmosphere. The event equaled the brightness of the full Moon’s reflected visible light,

This was a magnetar that created this burst. They are big, but no where near as big as a black hole!!!!!



Some history on the gas cloud;  Please see parts 1-7 on this blog history for more details!

First reported on December 14, 2011

This is the original article.  They have been watching this gas cloud since 2002, it is estimated be three times the size of Earth, and travelling at 5.2 mmph.  RIGHT AT SagA.  They expect it to be spectacular and arrive around Dec. 2012.

“However, since 2002, astronomers gazing through the Very Large Telescope have monitored a dusty gas cloud three times the mass of Earth zip at up to more than 5.2 million mph (8.4 million kph) in a straight line toward Sagittarius A*, putting out five times as much light as the sun as it speeds along. The cloud has now grown increasingly disrupted as it moves closer toward the black hole’s accretion zone — the region where matter begins its death spiral into the black hole.”

Milky Way’s Monster Black Hole Gets Colossal Meal



Then, a paper was published that describes this cloud as a ‘proto-solar system’, i.e. it contains a STAR and some rocky planets, surrounded by gas.  Many, many times more massive than Earth.

Updated paper December 20, 2011

For those so inclined:  Cornell University published the following PDF authored by Harvard/Smithsonian Institute for Astrophysics describing this new information in detail.  Don’t bother reading if you don’t like math.



This gas cloud was then reported on again with this update, moving the date to mid-2013 and leaving the possibility that it could either be a cloud or a solar system.  We will see.

Updated reporting on December 26, 2011

We should soon find out whose explanation for the gas cloud is correct. The cloud, whatever its origin, is on track to swing past Sagittarius A* in mid-2013. If it’s a simple gas cloud, it will get torn apart and partly consumed by the black hole, temporarily brightening the radiation from around Sagittarius A*. If the cloud instead comprises debris from a protoplanetary disk, the star itself should cruise past Sagittarius A* largely unscathed. But the cloud will grow denser as more and more mass from the disk is dragged away from the star. Either way, it ought to be quite a show.

So, be safe!  Watch SagA* for updates, and there will be updates!

Here is another variation on the whole ‘black hole’ thing.   This publication from NASA describes that an international team of astronomers has identified the moment when a black hole in our galaxy launched super-fast knots of gas into space

Unlike the Gamma ray emissions from SGR 1806-20 in December 26, 2004, this event was watched from start to finish!  This was a tiny PUFF from a small black hole that shows that actual event occurred 2 days (48 hours) before we got the radio waves.

Until now, astronomers had associated the onset of the radio outburst with the bullet ejection event. However, based on the VLBA data, the team calculated that the bullets were launched on June 3, about two days before the main radio flare. A paper on the findings will be published in the Monthly Notices of the Royal Astronomical Society

At least they mention the elephant in the room…

A super-sized version of the same phenomenon occurs at the center of an active galaxy, where a black hole weighing millions to billions of times our sun’s mass can drive outflows extending millions of light-years.
"Black hole jets in binary star systems act as fast-forwarded versions of their galactic-scale cousins, giving us insights into how they work and how their enormous energy output can influence the growth of galaxies and clusters of galaxies," said lead researcher James Miller-Jones at the International Center for Radio Astronomy Research at Curtin University in Perth, Australia.

The satellite  that was used for this survey, ended operation January 2012.
