Sry if this seems like tinfoil but i just cant get it.
So we have sattelites with further orbit than moon right?
Please give link to an actual photo of earth not some composed bull shit.
Something is going on and this might be the best brain wash ever. Not saying flat earth but hidden land or we just cant get further of some point. Also alot of the other NASA images ...you know, are fakes , there is documentation on this do your research. So a simple request , a photo of earth please :)

Have a nice day :) !

I first became interested in space exploration because of this website nearly eight years ago. Over that time space has piqued my curiosity enough that my dream is to work in a large observatory, or in a lab constructing instruments for spacecraft. I've spent a lot of time learning about the universe, and have simultaneously become interested in philosophy. I'm just really interested to learn new things about reality. It's such a marvelous and incredibly complex place, teeming with things to be discovered.

I want to know whatever is possible to know. Some things we might never be able to know, but I'm most certain that curiosity, as well as necessity, will drive our species towards distant planets in search of answers and new ways to survive as we go out. I really do hope that's how it plays out. Out of all of the possibilities, I think we'll always have a desire to travel into the next greatest frontier. We might travel inwards with digital worlds and biosynthetic machinery, but I believe the physical domain will continue to hold some deeper allure.

Study astronomy, which is basically physics and astrophysics.
If you wanna build shit then you need to study engineering.
Or you could study all of that + philosophy without a formal education and never accomplish anything in your life.
A man who chases two hares will catch neither, in your case you are chasing three.

Be prepared for inferior job security in your desired field even if you do get a doctorate in astronomy or engineering. You were born in the wrong time.
Space won't be hyped until long in the future. You would have loved the Cold War space race if you were around though.

But Venus is toted as the prime example of what could happen to our world if it got choked completely. Seems more likely a good idea to learn to live indefinitely in artificial environments like stations or Moon bases. In the long run that will be the most common living space moving forward into the cosmos.Terraforming is in the distant future and by the time we could do that we would already be able to live in orbit of every major body in this system if not leave it already.

Wait what? Did we see the same Inception? Inception didn't have any emotional scenes. It only had scenes where people were being emotional.

I just wondered, I have never heard of a microscopic telescope. By this I mean a device along the lines of a large nature-style camera lens or traditional telecope that is able to zoom in to the target area of a physical item and produce a 3d environment of that area through the lens? Surely theres an infinite amount of detail from a physical item We have all this advanced astronomical technology these days to look at things that lie in the distance. What would happen if technology was put into microscopic telecopes thanks everyone

The resolution of a telescope can be limited by a few things, diffraction, the atmosphere, the quality of the optics and the sampling of the camera. You suggest adding a microscope, in optics that concept already exists as focal extenders which increase the effective focal length of the telescope increasing the magnification. The problem is more magnification will only improve the resolution of a telescope if it's resolution is sampling limited, that means the pixels are too big to capture the full resolution. The vast majority of telescopes are not sampling limited, generally they are limited by the atmosphere or by diffraction if they are in space or use adaptive optics. No matter how much you increase the magnification you will never beat those limits. There is not an infinite about of detail you can achieve, there are physical limits such as diffraction. A telescope like Hubble is diffraction limited what you suggest would not improve it's resolution. You can only improve on diffraction buy building a bigger telescope or using shorter wavelengths.

You can't use this to make a 3D map either.

I know it's been a few months, but maybe you'll see it if you haven't bought one yet. I have a Celestron NexStar 102GT and it is awesome. It has the capability to track objects and it has decent magnification. It was right in the $200 range iirc, but I bought it years ago. I'm able to see the rings of Saturn(though it just looks like one ring). A couple of nights ago i realized Jupiter was in the sky and I was able to actually see some of the differing colors of the cloud bands. That was really cool. Pic is a snapshot from a video I took using a mount for my phone.

I have deduced that all living organisms are White Holes. I call this the Living Organisms as White Holes Theory.

Evidence :
  1. when the cells of a living organism divide, it emits minute levels of light.
  2. living organisms create and excrete their own matter.

Please help me compound on this theory I want to talk to a real scientist. I have more to add but I need to go do chores. More later, like being four dimensions opposite of zero. (thought. The final frontier)

I used to think that maybe a life form is like a bubble of negative entropy. All around the universe matter is getting less organized as systems disperse their energy, but in life matter harnesses energy to organize itself temporarily. But I was wrong. It doesn't make any sense to think of life as a closed system. We radiate so much heat and excrete so much shit that there isn't any logical boundary to call a bubble. There is temporary organization, but it is constantly part of the greater universe. Everything is causally linked. Especially EM waves. Photons are being absorbed and radiated by your cells. In a trippy way, doesn't that make you a physical part of your surroundings?

But long term, this would be cheaper than combustion. This would also work for manned missions.

You'd have to start decelerating 50% of the way there, if they're doing both with lasers. But they'd probably just use combustion to decelerate, which would significantly reduce weight too. Since it's for stopping and not the initial thrust. So I think that might work.

I realize it works great if you're just sending things out, but why develop this huge and incredibly useful ability and just use it to send out a dozen more voyagers?

>The biggest hint is that one of five speakers at the news briefing will be Lujendra Ojha from the Georgia Institute of Technology in Atlanta. Ojha made headlines in 2011 when he co-authored a study suggesting that liquid water flowed during the warmer months on Mars.

>He said at the time that, by accident, he noticed irregular features in images taken for another study of gullies in Mars craters. Using a computer algorithm to monitor changes over time, he began to see "finger-like" features and streaks that strongly resembled water. They would appear during warmer seasons and die away during cooler seasons. He has conducted research ever since, to determine if it is definitely water.
