Blackholes are the silent and massive monsters amongst us in the universe, but why can't we see them?
Firstly let's recap, blackholes are indeed black... very black. Not even light, traveling at the fastest speeds in the universe, can escape their gravity.
They are created when a star comes to its violent death, imploding and pulling all of the close matter into its centre. The mass within the centre becomes so great, the fabric of Space Time it's self begins to bend under its pressure, contorting it's self into a (currently theoretical) single point deep inside the hole.
But here's a fun fact, They aren't actually holes, but spheres just like anyother star.
So with no light escaping their spherical surface, we physically can't see them though any forms of electromagnetic light!
But what we can see is the stuff around them. This stuff is usually massive dusty donuts of matter surrounding them, being gradually drawn into their gravitational field. However this galactic dust is very dense, which makes seeing anything more then the blackness of the dust walls incredibly difficult.
But there is hope!
Today the NuStar survey has penetrated and began examining the dusty donut around NCG 1068. Not a catchy name, but in months to come exciting research will begin, hopefully uncovering the secrets held by blackholes.
