A real shooting star - Mira leaves a 13 light-year tail

deathcow says...

Astronomers are not totally sure about the ultraviolet fluoresence of the Mira trail. They think the bow shock of this star (the star is travelling at almost 300,000 miles per hour relative to the matter the star is colliding with) is producing enough heat to cause the gas to fluoresce. Think HUGE amounts of REALLY hot matter spread out in a gigantic tail in an environment with little conductive or convective heat loss. This thing would glow for a long time. (Like nebula surrounding the remains of a supernova where only the released energy of the event long ago has the shells of gas still glowing.)

Ultraviolet Ultimate Action

supersaiyan93 says...

I saw Aeon Flux first because the Liquid TV cartoon from back in the day was da bomb. But the movie sucked so hard, that when Ultraviolet came out (basically looking like EXACTLY the same caliber of film), I just couldn't force myself to ever watch it. Glad I didn't, judging by this clip.

Ultraviolet Ultimate Action

Isn't your comment the sorta thing more for the YouTube crowd? I get it. Not everyone likes the same things. But no one is twisting your arm. It says right in the title that the clip is Ultraviolet. If you think it was such a bad movie then don't watch it.

Resident Evil: Extinction (Cinema Talk Post)

If Milla Jovovich wants to leave try not to get in her way

Ultraviolet had a lot of potential, except Screen Gems kept cutting away at it. First they insisted that the story be half as long, cutting out a lot of the character development behind Violet, Garth, Six, and Daxus from the original script. Then they cut the funding for the movie, so Wimmer was forced to spread special-effects use thin, even though heavy effects use had been planned. And then finally, in order to appeal to wider audiences, they cut the movie down from 120 minutes to 84 minutes, focusing primarily on action. They also sanitized it, getting rid of the blood and various sound effects. (Crunching bone, screams of pain.) For example, during the finale of the movie, Violet loses 2 fingers in a fight, though this isn't shown and only lightly implied. There was an extended DVD released, but this didn't contain anything of great significance.

A novelization of a previous script (closer to the `120 minute long version) was released, and in this you can see a lot more of the character dynamic, especially focusing on Violet's past (her husband and child). It also points out her suicidal tendencies (she very nearly kills herself at one point) and the relationship she has with Garth is a lot closer. Also of note, the ending is a bit more ambiguous as to her survival. (I assume Screen Gems didn't want an unhappy ending, so they made her survival a lot more likely.)

Still, the movie did have some great moments. (The Blood Chinois fight being one of my favorites.) I'd have liked to have seen some of the planned final battles, such as Violet fighting against a bunch of soldiers who had their own gravity levelers and a more visible fight with Daxus (both were cut due to lack of funding.)

Anyway, forgive my long-windedness. I just thought it had to be said.

Lunar Eclipse From the View of STEREO-B Spacecraft

silvercord says...

A million miles from planet Earth, last weekend the STEREO B spacecraft found itself in the shadow of the Moon. So, looking toward the Sun, extreme ultraviolet cameras onboard STEREO B were able to record a stunning movie of a lunar transit (aka solar eclipse), as the Moon tracked across the solar disk. Each frame of the movie is a false-color composite of images made through four different filters that highlight temperature regimes and structures in the upper solar atmosphere. In this frame, large bright active regions, seen as dark sunspots in visible light, flank the Moon's silhouetted disk. The Moon appears small, less than 1/4th the size seen from Earth, because the spacecraft-Moon separation is over four times the Earth-Moon distance. Tonight, the Moon will find itself in planet Earth's shadow in a total lunar eclipse.

nice subwoofer!

"So is that damaging to your ears? Or do only high pitched sounds do significant damage?"

Damage to your (inner) ear occurs when enough energy is transferred to your hair cells, causing them to break.

A loud low sound like in this video has a low frequency (pitch) and a high amplitude (volume). As sound is just a displacement of air, at low enough frequencies with high amplitude it would basically just be a gust of wind (as you can clearly see).
The energy in a wave depends on its frequency and amplitude, imagine the hairs just swaying about 1 time per second..no big deal.
  15000 times per second however, all the while swaying just as far, the stress would cause them to break.
High-energetic waves have the potential to do more damage, just think of visible light ("low" frequency) and x-rays (high frequency). Even ultraviolet light, which is just beyond the visible light in frequency, can cause skin cancer.

A low sound that blows your hair about won't damage your inner ear.
Lower sounds could theoretically kill the hairs but your eardrum would sooner rupture..ouch?
The basic rule probably should be, if it hurts turn down your volume down to about 30% of that volume : S long term higher frequency exposure is a bitch.


Pathetic dude only looking for RED HEADS posts personal ad online

Okay, let me just throw this out there... if an albino breeds with a redhead, would their children be invisible? Would they spontaneously combust if exposed to bright sunlight? Would they fluoresce under ultraviolet? I'm just asking...
