Does that mean this blog is now over 400,000 miles long?!? That’s got to be the biggest comments page I have ever seen….

@ Soqueesh (54) -
“Embiggened” is a perfectly cromulent word. What’s your beef?

In case you are new here, you should know that the BA is a master of neologisms. Although some of the neologisms are evil.

“Embiggened?” Really? How does a fake word, a joke from an animated TV series, find it’s way into a science article? Don’t you have an editor?

There was something possibly relevant here that I read ages ago about Tau Bootis and its Hot Jupiter interacting – I’ll have to do search & see.

Okay, a quick vist to Wikipedia :

http://en.wikipedia.org/wiki/Tau_Bo%C3%B6tis

& from there onwards reveals that Tau Bootis and its HotJove seem to be in an interesting relationship :

http://www.space.com/scienceastronomy/050523_star_tide.html

Where the exoplanet wags the star!

Tau Bootis~wise, this excellent page gives lots more too :

http://www.extrasolar.net/planettour.asp?StarCatID=normal&PlanetID=19

Including illustrations and finderchart – it’s across from Arcturus and next to Muphrid (otherwise known as Eta Bootis – a metal-rich G0 yellow sub-giant just 37 ly off) in the sky.

Bodes well for aurorae (australis & borealis alike) too methinks!

@39. Anon Says:

The whole solar system is warming up…gee I wonder why

Actually, that’s a popular misconception that it turns out is NOT really the case – see :

& also here :

http://www.skepticalscience.com/global-warming-other-planets-solar-system.htm

plus check out this page :

http://blogs.discovermagazine.com/badastronomy/2010/10/26/climate-change-the-evidence/

from this blog which has plenty of other links incl. one to NASA’s climate change page providing the evidence for climate change and esp. Human Caused Global Overheating.

@23. Evan :

Off topic: What do you think of the claim that solar cycles are causing climate change?

I think the BA has it right here :

http://blogs.discovermagazine.com/badastronomy/2007/04/29/is-global-warming-solar-induced/

& there’s more resources incl. links and a NASA Earth science YouTube videoclip here :

http://blogs.discovermagazine.com/badastronomy/2010/02/24/nasa-talks-global-warming/

Again via this (Bad Astronomy) blog.

Its also worth checking out this :

http://www.youtube.com/watch?v=_Sf_UIQYc20&p=029130BFDC78FA33

great entertaining & informative Youtube video presentation overview of that idea.

Hope this helps.

Awesome image.

Can we take it that the latest Solar cycle is advancing nicely then?

@18. Ari Says:

Just curious but what happens when a planet passes through or near something like this. I can get a handle on size (and there are certainly planets that orbit host stars at these distances) but what kind of energy (or energy density) are we talking about? Bacon?

Good question. The stellar and planetary magnetosphere’s (magnetic fields) would interact and, yes, I suspect the planet would likely have even more energy and heat dumped on it than usual but to be honest I’m not sure.

There was something possibly relevant here that I read ages ago about Tau Bootis and its Hot Jupiter interacting – I’ll have to do search & see.

It is amazing that Hot Jupiters can survive being so close to stellar flares, CME’s etc .. although I think they are slowly getting evapourated away and their outer layers get boiled off them streaming away like cometary tails and possibly eventually reducing the planet’s to stripped down molten (plasma?) cores over aeons of time.

Actually, robsol (44), it *is* UV. It was from the 304 nm filter on SDO. If you click the pic you’ll see the caption.

The red photo is actually a Hydrogen Alpha composition, with filters tuned to allow only visible light at the frequency 656.28 nm. This is characteristic of all HA shots – It is not a composite false color or an ultraviolet picture as erroneously reported in the column. You can actually see this filament with a basic solar telescope for about $500.

To put it another way, the diameter of the Sun is about 110 times the diameter of the Earth. The reduced-size image at the top of Phil’s post is 620 by 620 pixels. Given it does not go right up to the edges, the Sun covers somewhat less than 320,000 of the image’s 384,440 pixels. Earth would have a diameter of about 5 pixels at that scale, and cover an area of about 20 pixels. You can click through to the full 2048 by 2048 image. The earth would be about 18 pixels across, and its disc would cover about 270 pixels.

Here is a (rather rough) image – http://www.nasa.gov/images/content/105298main_sun-comparison_lg.jpg

It was very cool, the info about the UV was interesting. But what shot this past cool into amazingly fabulous was the use of “Embiggen.”

Mahvelous. Thanks for sharing!
