Not done but getting there.
Not done but getting there.
He’s actually telling this story to his 2 kids? Holy hell.
I don’t have a telescope that I can hook a camera up to.. and if I did have one, my camera is not good enough. So anyone can do this and many of these things look similar to what you’d see through binoculars. I would say a fair chunk of these can be visible in good enough sky condition.. or with the averted eye trick. Some things pop out better when you aren’t staring directly at them. Hopefully me bringing them out makes it so one wouldn’t have to go to all this trouble though. Hopefully whoever looks at this enjoys it and appreciates how large and far these things are. Maybe photos of us are being taken from one of these points? Most these nebulas are several times larger than the farthest reaches of our own, puny solar system.
For example, at the bottom, M7 (Ptolemy’s cluster) is about 25 light years in diameter. The Lagoon Nebula, M8, is about 25 by 55 light years, but appears smaller since it’s over 4,000 light years from us. Ptolemy’s Cluster is less than 1,000 light years from us. By comparison, our solar system is nothing. Even if you extend out past the Oort Cloud on both sides, we are 1-2 light years wide at the absolute maximum. In all actuality, we are smaller than a light year. The orbits of our planets and dwarf planets extend out maybe a couple light DAYS. Earth is around 9 light minutes from the Sun. MINUTES.
In this photo I brought out and marked all the visible points of interest near and around the direction of the Milky Way’s center.
Star clusters and nebulas galore (for the most part).
Space.com is amazing and I highly recommend daily visits.
I’ll try to sum the article up fairly quickly here. There is a lot of really compelling evidence that life didn’t start here. Now, a new study basically gives data to support that life HAD to come from Mars. At least, life as we know it.
I will try to keep this short, but at the time of our genesis (not the Bible kind) we were a ‘young’ planet covered in water, desperately lacking in the oxygen needed (for several things). This means we lacked a vital gas needed the sustain the long lineage that leads to our species.. it also means we don’t get the oxidized minerals which played an absolutely vital role in making the organic soup of which we rose. Not to mention that the water covering our planet was corrosive to RNA, one of the big fundamentals in life.
Okay, so we had very little oxygen, water is corrosive to RNA, and we lack oxidized minerals which would allow life to even begin. Where would we get such things?
What? The entire Mars surface is/was oxidized? And.. what? There was water there, along with oxygen (yep, it had it at this point) and dry stretches of land where oxidized minerals lie for the taking? Oh, and our placements of both of our orbits practically promote exchange of minerals from Mars to Earth (not the other way around)?
Well, gee whiz.
Also, NASA scientists explain that it may not just be the needed materials that were Mars-born, but there are several microbes that are hardy and could survive an impact and subsequent interplanetary journey from Mars to Earth.
