Марсианские истории.

Sun, 30 Aug 2015 19:33:19 GMT

«Самки термитов в гнезде лежат так, что ось их тела совпадает по направлению с магнитным меридианом Земли, а если поместить рядом сильный магнит, то меняется и их положение».Из книги для учащихся, Минск 1984 г.Выживание биологических видов часто определяется не глобальными катастрофами, а комфортными условиями для жизни вида в данных экологических условиях. Очевидно ресурсы одной планеты, пригодные для для разумной цивилизации, насчитывающей миллиарды особей, склонны к быстрому исчерпанию, что приводит к появлению сначала некоторого дискомфорта, после – войн за ресурсы для выживания. Сама подготовка к длительному изолированному существованию в глубоком убежище подразумевает накопление самого необходимого для выживания – газов, необходимых для дыхания, жидкостей и самовоспроизводящейся биосферы, требуемой для питания. У большой планеты длительный квазистационарный период позволяет не задумываться о медленном изменении химического состава окружающей среды, но Марс в этом смысле оказался куда менее стабильным, чем полагал великий вождь светлой расы марсиан Мутин. Он сплотил вокруг себя преданных ему единомышленников, убеждённых в том, что только Единый Марс может выжить в ситуации энергетического кризиса и решил наращивать военный потенциал, накапливать ресурсы для выживания, закачивая марсианскую атмосферу в подповерхностные хранилища. Риск войны был высок, а победа над соседним государственным конгломератом, объединившим вторую половину населения Марса, была просто необходима. Резкий скачок технологий, позволивших обеспечить вещание СМИ на всю планету и каждому предоставить мобильный смартфон с массой полезных функций, давал возможность каждому марсианину выходить в глобальную сеть – экстернет. Это постепенно начало менять взгляды сторонников Единого Марса в сторону отказа от войны с серыми, поэтому правительство решило издать указ о запрещении чиновникам светлых выходить в рабочее время в экстернет, а нарушителей – штрафовать.Учёные, приглашённые Мутиным, рассматривали перспективную идею переселения на большую жаркую планету, третью от Солнца, где по данным автоматических спутников жизнь развивалась пока без признаков разумности – на планете царствовали огр[...]



Origin of Saturn's F-Ring and Satellites revealed!none

Wed, 26 Aug 2015 23:02:53 GMT

According to the latest theories regarding Saturn's satellite formation, Saturn's rings had many more satellites during its ancient accretion phase than it does today. During the final phase of formation, satellites tend to form further out.

Критиковать конечно легче…

Fri, 07 Aug 2015 16:09:53 GMT

«Согласно обшей теории относительности время замедляется в поле гравитации». Очевидно надежды обнаружить в классической теории ошибку и предложить свою собственную модель присуща даже школьникам, но в отличие от них я не пытаюсь доказать несостоятельность некоторых следствий из первого предложения, а ставлю под сомнение сам принцип – не только время замедляется в поле гравитации, а также гравитация возникает как следствие в результате неоднородности скалярного поля времени. Соответственно первая элементарная причина гравитации – возникновение неоднородности темпа хода времени в присутствии массы. Вероятно существование и некоторых других причин, в результате совместного действия которых появляются локальные области с иным темпом течения времени (что создаёт эффект тёмной энергии и тёмной материи). Из данного постулата есть множество следствий, которые необходимо проверить, соответственно ваше желание доказать или опровергнуть экспериментально вашу модель так же помогут найти ответ и на мои вопросы с намерением защитить свои авторские права на менее амбициозную (без телепортации и точек Z) но не менее значимую космологическую модель.Искать доказательства замедления или ускорения хода времени в «поле гравитации» с помощью атомных резонансов таким образом представляется бесполезным, как измерять резиновой линейкой длину метра при околосветовых скоростях. По теории ЭМП в некоторых случаях электричество порождает магнитное поле, в некоторых – магнитное создаёт электрическую разность потенциалов. Можно искать в электромагнетизме отдельно магнитную или электрическую компоненту, удивляясь их странному поведению по отдельности, как в проекте LIGO, занимающимся поисками гравитационных волн в виде искривления пространства, ищут чёрную кошку в тёмной комнате. На данный момент сообщений об обнаружении искривления пространства не поступало. Думаю в комнате просто надо включить свет: результата нет из-за того, что закралась методологическая ошибка – искать нужно волны времени. Математические законы, описывающие реальные процессы, всегда выполняются только в диапазоне значений, выходя за рамки которых невозможны «идеальные условия» или инерциальные систе[...]



About Pluto...question.Depeche Mode: Violator

Wed, 08 Jul 2015 17:15:02 GMT

I hate to sound rather dumb-but anyhow. Is Pluto still considered a proto-planet or is it now considered a dwarf planet? I may sound a bit behind the times but last I heard was that Pluto is a proto-planet.

P. S. Does anyone know when the next Pleiades meteor shower will occur? I want to be able to watch it.



Next Solar Eclipsenone

Fri, 29 May 2015 18:40:13 GMT

How many of you in North America will be watching the heavens for or during the next Solar Eclipse on Monday, August 21, 2017? I myself will have to keep my eyes glued to the television as that will be my safest bet because I do not have the equipment necessary to safely view this spectacular event. I hope you are as excited as I am about it!

Earth at Night

Sat, 18 May 2013 06:43:05 GMT

I'm not sure if this community is active anymore, but does anyone know where I can get a large number of maps over a long period of time (years and years) of the Earth at night? All I can find are the latest pictures with a scattering of a few older ones because everyone is agog over the NASA/Google partnership using the Suomi satellite.

Annular Eclipse on May 20 2012

Sun, 17 Jun 2012 04:35:20 GMT

 May Sunday 20-  I arrived at the Joshua Tree National Park Visitor’s Center in Twentynine Palms a little after 3PM. There were around twenty folks and a few Park Rangers setting up and preparing for the eclipse that wouldn’t begin until 5:24PM.One Ranger was using a paper hole-punch to make viewing devices out of thin cardboard stock. The lady Ranger told me she had 200 special eyeglasses for viewing the eclipse and she was hoping it would be enough for those who came to the event.Two Astronomy volunteers were in the last stages of setting up their telescopes and people began to lineup to observe the Sun and its sunspots; the eclipse was still hours away.There were folks from all over the world here to see the annular eclipse. I got into a conversation with a visitor from New York State. He came all the way out here to take pictures of the eclipse with his Cannon 7D and this humongous zoom lens stuck to the front. Around 4:15PM folks started showing up. The Rangers were showing the kids how to work the pinhole cardboard device, which we discovered later, had too big of hole from the punch and had to be redone by poking a new hole with a nail the Rangers supplied. By 4:45PM there were, by my best guess, upwards towards 400 parents with their kids standing in line to get those 200 special viewing glasses. Clearly there wouldn’t be enough. The Ranger asked that only one pair be handed out per family. I decided to wait so those who never seen an eclipse before would get a pair.One Astronomer volunteers had connected his scope to a projector for viewing the eclipse on a large movie screen. And at 5:24PM the eclipse was beginning and by 5:30 could clearly be seen on that screen. There upon the table by the projector were a few pairs of glasses left and I made off with one. I held it up to the lens of my camera and started taking pictures of the eclipse. I don’t know if I was the first to try this, I didn’t see anyone doing this before I tried it, but now everyone was taking pictures through them using their cell phones and whatever that could go click.I went here and there taking pictures and videos, listening to folks laughing, oohing and aahing, wearing those funny looking glasses that made it look like they were watching a 3D movie. It was mighty fine to see all these folks interested in astronomy. I listened in on one father explaining to his young son about the eclipse; this touched my heart.At 6:38PM came totality or as close to it as we were going to get from where we were and it being an annular eclipse. You could really notice the dimming of the Sun. I lent my glasses to a young couple from Belgian. They were traveling America and were really excited to be here in our beautiful desert viewing this marvelous feat of nature. I took some fair pictures, but none as good as the ones I took as the Sun and Moon started to set together into the western horizon. I didn’t even need those glasses covering my lens. I just clicked away until the last little speck of light vanished; ending what was a wonderful day. The Park had a night program that started at 8PM. The Rangers setup two telescopes to view the night sky. Now I was in my element![...]



Partial Lunar Eclipse June 04

Sun, 17 Jun 2012 04:23:38 GMT

(image)

At 1:30AM I went outside and got everything setup for the Partial Lunar Eclipse that would be starting in about half an hour. I had every camera I own sitting on the table ready to shoot the Moon! About 2am it started and I was clicking away, trying different settings on different cameras, to get a good shot of the Moon. At 4:03AM it was at as eclipsed as it was going to get. That’s when my neighbor’s rooster started crowing- stupid rooster. I stayed out a little longer and then started putting everything away. I didn’t get to bed until way after 5AM.



Venus Transit

Sun, 17 Jun 2012 04:14:20 GMT


(image)
My only good shot of the Transit- but I did it and won't have to wait 120 something years :)
The Transit of Venus started at 3pm and I went to Kelly’s house to watch it. Yes and Venus is 60 some million miles from the Sun and 30 million something miles from us on Earth! We live on a wee teeny tiny little speck of dust; the flotsam and jetsam which obit the huge Sun. We got a few picture of the transit with my camera. We quickly went down to Staters Bros. and got some hamburger meat. We got back and continued to view the transit and take pics until sunset. Then we watched it on NASA TV using my iPad. I had to make a special run back to Staters because the butcher put way too much seasoning in the hamburger meat which made it unfit to eat. Kelly made some mighty fine cheeseburgers, she's a fantastic cook! This day was among one of the best days of my life!

Venus Transit - 2012

Wed, 06 Jun 2012 08:53:45 GMT

I knew when the transit was supposed to occur, so I was set up and ready to go. There was about a 15 second break/thinness in the clouds, and I took 6 photos.

I really didn't think I had gotten anything.

Oh me of little faith.

(image)


This is cropped down and the itty bitty dot that is Venus is a bit difficult to discern, but it's on the bottom left curve of the sun.

Also, the reason the photo is bluish in color, is stack of filters to prevent my retina from being burned out. That's why I thought I hadn't gotten anything, the images on the screen looked like a bright spot on a dark background, with no details. Should have known to check on the big screens first.

2CA vs Stellarium

Tue, 06 Mar 2012 00:48:05 GMT

Does anyone know if 2CA is compatible with Linux? I have Stellarium, but it doesn't seem to work in the same way...maybe I'm just not use to it...? Any insights?! Thank you!



WOW this community is quiet

Thu, 05 Jan 2012 23:42:08 GMT

Can´t believe no one posted THIS yet!

Also, I´m particulary interested in this part of the article, but I´m not following what it´s saying about how the method of detecting planets works:

Confirmation of a planet, however, requires additional observations, usually of its star’s wobbles as it gets tugged by the planet going around. The gravitational pull of planets as small as the Earth on their parent star is too small to measure with the current spectrographs. And so the astronomers resorted to a statistical method called Blender, developed by Dr. Fressin and Guillermo Torres of the Harvard-Smithsonian Center, in which millions of computer simulations of background stars try to mimic the Kepler signal. They concluded that Kepler 20e was 3,400 times more likely to be a planet than background noise, while the odds in favor Kepler 20f being real were 1,370 to 1.

Someone can clarify this for me? Please and thank you!

An odd question of sorts

Thu, 13 Oct 2011 20:49:22 GMT

Kind of an odd question/request here...but I'm interested in adding some friends who are either students or teachers of astronomy or who work in the field of astronomy (cosmology and astrophysics will work too), and write about your experiences involved with astronomy (cosmology or astrophysics) in your journal. I've been working on my second novel over the past year, and several of my characters are either students or teachers of astronomy or work in the field of astronomy. I'm not looking to use your likeness in any way, shape, or form! I'd just like to get into the head of someone who works closely in the field or academic setting so I can fine tune some details :) Anyone involved with SETI would be ideal as well! Thank You!

Here are links to my profile and journal intro so you get an idea of who I am before you decide to let me read your journal (and, of course, I will add you back as a friend so you can have full access to my entries as well :)
