QuoteAstronomers writing in Monthly Notices of the Royal Astronomical Society say they have discovered the darkest known exoplanet, a Jupiter-sized gas giant called TrES-2b. Their measurements show that TrES-2b reflects less than one percent of the sunlight falling on it, making it blacker than coal or any planet or moon in our solar system...
Quote... The star's intense light heats TrES-2b to a temperature of more than 1000 degrees Celsius, much too hot for ammonia clouds. Instead, its exotic atmosphere contains light-absorbing chemicals like vaporized sodium and potassium, or gaseous titanium oxide. Yet none of these chemicals fully explain the 'extreme' blackness of TrES-2b.
The capabilities of the Keplar spacecraft are pretty impressive, if was able to detect this planet. Plus, this discovery is sort of huge, considering we've never previously detected anything like it. I'm curious what a few hundered thousand of these guys floating around the galaxy does to the calculations determining the amount of dark matter in the galaxy. Probably not much, but either way, it's definitelty something to keep in mind every time you start to think about the over-all weirdness of the universe.
Villager and I were actually discussing this planet over the weekend. It's pretty damn cool. It's really a pity that we can't physically go there and check it out. It's shit like this that would actually get me to leave Earth, provided the technology was available/possible to go take a peek at it. I imagine it would be very easy to crash into though, against the backdrop of space.

I appreciate your zeal, however, I must say that it seems a little weird to me that a planet 750ly away with a surface temp of over 1000 degrees celcius is what would motivate you to leave earth, when the possibility of exploring and colonizing worlds and moons within your own solar system doesn't?
I mean, yeah. To see this up close and personal would be fantastic, but we need to do something within our own solar system long before we ever get semi-close to TrES-2b.
So, change your motivation around a bit: You want to see TrES-2b? Well, we're going to need to explore/colonize the moon, Mars, Titan, etc. first. SO LET'S DOO EET!

I guess my motivation is a little more tied to the "getting back to earth" capability. If I could feasibly travell 750 light years, I'd totally hit up everywhere else here on the way. Exploring is what I would be interested in, and implies that I'd come home at some point.
This of course, is presuming that we develop some sort of method of deep space travel in a timely fashion that does not create time dilation. I'd want to come home to approximately the same era. Tall order, I know. I should put in my application for godhood.

Need a fast car for that. Though I imagine with your mad science, it's not too much of a problem. Just be sure to bequeath your schematics to me and dimo, so we can go look at stuff. 8)

And a REALLY wide elliptical orbit. At that point, if you're covering the distance anyhow, you may as well check out some other stuff. Primate free? I'm sure there are many planets out there that can accommodate you in that regard.

Heh. Well, that's sort of my goal. I've always been interested in space (astronomy, cosmology, etc.), but until recently I've been using the excuse "I can't do math, let alone the math needed for this feild" which was a horse-shit claim I made to avoid having to work towards knowledge. I'm happier now, for having expanded my view of reality to include the language of numbers, and my understanding of the cosmos (Earth included) has expanded due to this.

You can't mix Irish and Italian.
The result puts a hit out on itself.
It's a tough nut to crack, though. Automatically included in the study of space are things like geology, quantum physics, meteorology, chemistry, etc.
Not to mention the area in which I'd like to study the most, the potential of life in space (other forms of life, as well as human life in space) relies heavily on other things, such as organic chemistry and the such.
It's a long row to hoe, but, for me, the pay off is worth it.

Ahahaha. +Tuscan, so I get the crazy hair ++tuscan.afro(after 4 weeks). :argh!:
On the subject, very cool find.
I have to agree on the math, as well. Definitely have a different appreciation for art now that I can pin rough values on all the, say, bounced light in painting vs whitepoint vs shadow if I wanted to. Recognition of techniques (and use of...) gets easier too.

I'm curious what a few hundered thousand of these guys floating around the galaxy does to the calculations determining the amount of dark matter in the galaxy. Probably not much, but either way, it's definitelty something to keep in mind every time you start to think about the over-all weirdness of the universe.
Yeah, I would doubt it would do much, not only because it is small, but being at about 1300K and a very good absorber, it probably would emit some black-body radiation in the IR region.
Still, very cool. My favourite things about exo-planets is finding ones that are completely different to those in our solar system.
Perhaps the entire surface is covered in a highly efficient solar energy collecting system for use by its inhabitants.
:)
also, i find it interesting that this article mentions one of the light absorbing constituents of its atmosphere to be gaseous titanium oxide, considering that the titanium oxide i am familiar with is such a bright white...

Yeah, I think it said in the article that it did give off some faint light "like an ember in a fireplace." I guess what I meant to say was, if the materials that compose the surface of the planet are blacker than any known black, that opens up the possibility of other objects having the same or similar composition that aren't orbiting a star, that would be practically invisible to our methods of detection. Even still, it probably wouldn't account for a sliver of all the dark matter in the galaxy. I probably shouldn't have even mentioned it, TBH.
So, this planet is blacker than black, and has an atmosphere made of burning hot vaporized metals?
I do feel that it is appropriate to dub this THE MOST FUCKING METAL PLACE IN THE KNOWN UNIVERSE.
Lol yup. Honestly its hard to think of metals existing in gas form. Technically thought they are compounds formed by metals and therefore may have different properties.
mercury vapor is just straight up mercury, isn't it?
Yeah but it has titanium oxide
yeppa. i was just thinking of gaseous metal, and mercury vapor lamps immediately pooped to mind.
now i'm thinking about what titanium oxide that is just at the threshold of vaporization might look like going from bright white to dark black and back...
