What telescope do I need to see IC1011?
Since IC 1011 is a galaxy, you'll need dark skies. No filter will fix this for you. It's listed as magnitude 14.7, which suggests a 10 inch (254 mm) telescope. My experience with galaxies is that you'll need more than that, or long exposure photography. Fortuneately, with clear skies, even an 80 mm scope could eventually bring in enough photons for long exposure photography to work. I belong to a club that has a 10 inch SCT with a first rate camera that could get an image. There are even people who could show you how to set it up. But it's doubtful that the skies at the observatory are up to this task. The equipment is portable, but by policy hasn't yet been moved. I belong to another club that has a 16 inch (400 mm) SCT in an observatory, but the skies are probably not up to imaging more than about the four or five brightest galaxies in the skies. There are certainly clubs that have equipment for something like this. Find one near you. http://www.skyandtelescope.com/community... http://en.wikipedia.org/wiki/IC_1011
What is the largest black hole known to mankind?
The largest black hole found so far is S5 0014+81, which has a mass of 40 billion M☉ (solar masses). It is thus relatively close to the theoretical upper bound for the mass that a black hole can acquire through the conventional accretion disc method.[1] At 40 billion M☉, S5 0014+81 has a Schwarzschild radius of 790 AU (a diameter of 1580 AU).In the image above you can see S5 0014+81 compared to three size estimates for the Solar System:The Solar System with a diameter of 80 AU (yellow) — A conservative estimate of 80 AU in diameter.The Solar System with a diameter of 150 AU (orange) — The termination shock (the point where the Sun’s solar wind collides with the interstellar medium) can be found at a distance of 75–90 AU.[2]The Solar System with a diameter of 180 AU (blue) — The termination shock (the point where the Sun’s solar wind collides with the interstellar medium) can be found at a distance of 75–90 AU.Footnotes[1] [1511.08502] How Big Can a Black Hole Grow?[2] Heliosphere - Wikipedia
How long would it take to reach the Andromeda using today's technology?
A Bugatti Veyron’s top speed is around 270mph. If you could somehow modify the Bugatti Veyron’s engine so it reached the speed of light instead of 270mph, it would take about 2.54 million years to get there.Andromeda is 2,538,000 light years away, and at the speed of light, at which none other than light can travel, it would take 2.54 million years to just get there.The average human lifespan is 71 years. Therefore, if NASA decided to send a probe to Andromeda in 2018 (HIGHLY impossible):35,774 generations of humans would have set foot on Earth before the probe even reached Andromeda, though due to time dilation it would be possible for a human to travel further than their 71 active years at a constant speed of c = 300,000 km/s.Likewise, is a NASA spacecraft travelling at 28,000 km/h was sent towards Andromeda, it would take about 844.7 trillion hours, or 7 x age of universe, or just about 94.5 billion Earth years.And here we are, complaining about the long hours of schools and offices.
