Stunning time-lapse video of the Sun: "NASA | SDO: Year 5" What word(s) would you use to describe the time-lapse imagery of the Sun from NASA's Solar Dynamics Observatory spacecraft? From part of the YouTube description: February 11, 2015 marks five years in space for NASA's Solar Dynamics...

Not sure if this has already been posted but I stumbled onto this pic at the Discover Magazine website. It was taken in the hydrogen alpha part of the spectrum. Click on the pic for a bigger version. Pic of sun Steve S

Hi I haven't posted here for a long time. There's a lot of videos on youtube showing two suns. People think it's a planet called Niburu and apparently it's just come in to our solar system. If it just came in to our solar system does it hide when I look out my window? I haven't seen another...

First Ever STEREO Images of the Entire Sun This was all cool. Or hot. This part especially:

Just read this at discovery.com Some researchers from Stanford and Purdue claim to have measured a variation in radioactive decay constants over time. Moreover, the variation apparently correlates with season and solar activity. Could this be possible? Why has no one seen this before?

There is a large CME inbound, resulting from a flare and coronal eruption that occurred at 0300EST this morning. It is expected to reach Earth on Tuesday, Aug 3. http://news.discovery.com/space/incoming-the-sun-unleashes-cme-at-earth.html#mkcpgn=rssnws1

http://beta.thehindu.com/sci-tech/energy-and-environment/article458070.ece Sounded worryingly catasrophic until I saw the source of that last line :rolleyes: Sure the 2012 conpiracy nuts are going to absolutely jump on this. NASA...

A new episode of the History channel's Universe series: What would happen if the moon disappeared? Seems ironic, given the recent thread on what would happen if the moon doubled in size. According to the show, two things mainly: The tides held by the moon would run off, causing "powerful...

I have been reading over the past few years about the integration of nanotechnologies and solar power. Also, there is a company, NanoSolar, claiming they can produce energy at a cheaper cost than that of coal. Is it true? How soon before all warm-weather states' roofs are covered with this stuff?

Gravity or Electromagnetism(EM)? Which is stronger? Which matters most? In another topic, which is about Plasma Cosmology, whatever that may be, the statement came up again, about Gravity being "stronger" than Electromagnetism. The first time I saw that I simply checked, and EM is 1039...

The motivation for this thread comes from a post by Zeuzzz, in a lengthy Science, Mathematics, Medicine, and Technology thread, here is the post. Here is the relevant part of that post: I am curious: Since Alfvén first proposed this heliospheric current circuit, many decades ago now, the...

Whilst it's widely known that it's dangerous to look directly at the Sun, is it dangerous to look at it through a deep haze? I live in the Middle East, and in the late afternoon, when the Sun's low, the Sun's brightness is often diminished significantly because of haze. It's difficult to know...

Ok, so this is not new news, but I find it interesting. I did a brief search on the forums and did not see a mention of it, at least not for awhile. However, I find it quite interesting that there is some evidence, mostly statistical, that our Sun might be part of a binary star with another...

There is a theory that the sun is not powered by internal fusion but by electric currents that exist in the galaxy. This started is a plasma cosmology thread but it seems to warrant it's own thread. http://www.electric-cosmos.org/sun.htm Gives an overview of the model, if I understand the...

I ventured to JRE, because I found out from my 'referrence' stats from my website that people were accessing http://www.geocities.com/davidjayjordan/432KeyofStarofDavid.html from HERE.... In case, it was being discussed without me being present, I figured I might as well join...as there...

My question is simple: What are the major differences between the photons emmited by the sun and those emmited by say a lamp? I know that if you go outside and place a magnifying lens over say a small stack of dried leaves, you can set them on fire by focusing the rays into one point on the...

So, I'm getting my daily dose of infotainment this morning watching "Today". They're talking about the heatwave hitting the northeast and the nitwit commentator shows a construction site in Boston where some guys are climbing a tower/crane and says something along the lines of how terribly it...

I'm just listening to Randi's latest appearance on "The Skeptics Guide to the Universe." Excellent interview. Update on his bypass. Some Benny Hinn debunking. Cars with water-only engines. Fox News reports on the water car. Oh-Oh... Randi: The announcer actually says, "He generates from...

In his artice from last year Seth Shostak mentions about means to rejuvenate the Sun: What is he talking about? This is something I haven't heard before, although I'm familiar with the term terraforming, for example.

I was discussing the death of our Sun with a friend and we were unsure of some details. We generally agreed that this is the possible order: From HERE. Q's: How far into the planetary orbits will the Red Giant expand? Are the outer gas giants safe? Is the black dwarf stable or will...

I'm not sure if it was just a claim I saw, or if Randi actually discussed it and it was up here, but remember that guy who said he didn't need to eat and he got his nourishment from the sun? (run on sentence, anyone?) I've searched around but I can never get the fields right and I'm not...

http://news.bbc.co.uk/1/hi/sci/tech/4726733.stm Does this mean that there are really 11 planets in the solar system rather than 9? As an interesting side note, how would this new "object" be affecting all those sensitive charts astrologers spend ages on ;)

Alright, I was just sitting around thinking about things, and these questions just popped into my head. After all I've learned here, all I thought I knew but really didn't, and how decieved I was before, I'm going to ask this seriously. Is the big risk of skin cancer and the absolute need for...

http://www.catholicintl.com/epologetics/articles/science/cole4-1.htm The above link is an account of someone trying to prove the Earth revolves around the Sun, and the subsequent "debunking". Count how many times you slap your forehead while reading. 3 for me. Particularly after reading:"Is...

The Sun newspaper has been carrying out a survey of beliefs. It has found that the majority of people still believe in a God in the UK. Fair enough. What is slightly more offensive is the tone in today's paper which firstly implies that it is basically one in the eye for "Intellectuals and...

Debunk powers needed: http://www.worthynews.com/icr-sun.htm This link was given in a discussion I have with a person who says that Lithium in the Sun proves that God exists. I'd like some debunking of the link, but I'd also like some specification about how much Lithium there is in the Sun...

Did anyone else catch the "Climate Conflict" program on The Science Channel last night? I thought it did a pretty good job of explaining conflicting theories on global warming, in particular Henrik Svensmark's data showing that changes in the Sun's magnetic field correlates to Earth...

OK, a question: I was having a discussion about JK's lil comment about gravity/marbles on the highway (from a past thread) with a physics doctorate the other day, and he posed this question: If the sun suddenly disappeared *poof*, we would only notice it gone after 4 minutes in terms of light...

Sun's Output Increasing. Now how will the anti-environmentalists who have denied global warming is taking place use this? Because to use it is to admit there is global warming taking place. Since this article takes some of the solar wind out of the environmentalists' sails, will both sides...
