First ever black hole image released

Astronomers have taken the first ever image of a black hole, which is located in a distant galaxy.

Astronomers have taken the first ever image of a black hole, which is located in a distant galaxy.

It measures 40 billion km across - three million times the size of the Earth - and has been described by scientists as “a monster”.

The black hole is 500 million trillion km away and was photographed by a network of eight telescopes across the world.

Details have been published today in Astrophysical Journal Letters.

Prof Heino Falcke, of Radboud University in the Netherlands, who proposed the experiment, told BBC News that the black hole was found in a galaxy called M87.

“What we see is larger than the size of our entire Solar System,” he said.

“It has a mass 6.5 billion times that of the Sun. And it is one of the heaviest black holes that we think exist. It is an absolute monster, the heavyweight champion of black holes in the Universe.”

The image shows a intensely bright “ring of fire”, as Prof Falcke describes it, surrounding a perfectly circular dark hole. The bright halo is caused by superheated gas falling into the hole. The light is brighter than all the billions of other stars in the galaxy combined - which is why it can be seen at such distance from Earth.

The edge of the dark circle at the centre is the point at which the gas enters the black hole, which is an object that has such a large gravitational pull, not even light can escape.

I'm a girl and I love science 😀

Science Side of Tumblr, I need your help!  Ladies of the Science Side of Tumblr, I especially need your help!

I had a conversation at my non-science day job that went like this:

A friend who shall be called Diane (not her real name) comes to my desk to chat.  Just one of the many topics we discuss is that her boyfriend is  taking a class in wildlife biology.  She has decided that she has grown tired of hearing about local wildlife and hearing him recite a plethora of scientific names. 

I responded positively to this subject, and told her that I too found the subject interesting.  A third person had heard our conversation.  We shall call her Claire (again, not her real name).  Claire immediately responded, “Girls don’t like that kind of thing.”

“Are you saying that girls don’t like science?” I asked.

“No, not normally they don’t,” she responded.

Before you all screech with anguish, bear with me for a moment.  We all know that this is not true.  As a man, I find this idea upsetting for countless reasons that have all been validly discussed before.  To try to debate the issue is rather moot.  Instead, I’d like a show of hands.

Ladies of the Science Side of Tumblr!  I call you to arms!  Will you rally around me in saying that women can and do indeed love science, of any variety?  Gentleman of the Science Side of Tumblr who know someone who is a girl who also happens to love science, will you stand with me too?  We all like and reblog the pro-women-in-science posts we see so often, let’s all stand and be counted in one place this time.

Reblog this if you are a woman who loves science.  Reblog this if you are a man who knows a woman who loves science.  Let us disprove her beyond all doubt!

Anxiety is like constantly hearing the battle or enemy music but never seeing the actual threat.
