All you have to do to build a road is to flatten out the area and pave. Bridges involve huge work crews, engineers, and way more heavy machinery. It’s almost never cheaper to build a bridge over something unless the alternate route is way
It’s both a breathtaking and slightly depressing photo, because it emphasizes how very close to Earth most manned space travels have stayed in the last decades: not much more than 340 km / 211 mi, the distance at which the ISS orbits our planet.
>or by the expansion/contraction of the space between us and the star? Firstly, the space between us is expanding only. See [cosmic inflation](http://en.wikipedia.org/wiki/Cosmic_inflation). Secondly, the redshift is a result of both inflation and sidereal motion but mostly the latter as its effect is far
>This view shows several of the ALMA antennas and the central regions of the Milky Way above. In this wide field view, the zodiacal light is seen upper right and at lower left Mars is seen. Saturn is a bit higher in the sky
No I’m saying actual pixelation in the mountains at the bottom, not the orange glowy thing. It’s cool though!
there’s a lot of gravitational evidence for the existence of dark matter (dating back to the 1930s), ranging from rotational velocity curves to gravitational lensing of galaxy clusters, as well as indications from numerical simulations. it’s not just far away galaxies, there’s evidence from
According to [this](http://www.bbc.com/news/science-environment-29932609) HL Tau is 450 light years from Earth. This means that the image we are seeing right now is 450 years old. On the cosmic scale that isn’t a lot of time so more than likely the HL Tau system currently
Delta-v is the total energy in the MMU described in terms of how fast you would go if you used it all in one direction. Acceleration describes how quickly that energy is expended. For example, if he started out not moving and used all
Thanks for the feedback, both clarity and sharpening are only on +7 but vibrance is much higher, will tone it down for the portfolio. Appreciated.
Many long-exposure aurora pictures are brighter than the real thing appears to the eye. I can tell this is one of those, so you wouldn’t be able to see as much glowing in the dim areas with the naked eye. However, these long exposures
Fantastic! For those who don’t know these are mammatus clouds formed in the ash cloud downwind of the mountain. It’s the same thing that can happen on the underside of the anvil of a large thunderstorm. It’s technically debatable what specifically causes them from
Yeah, I didn’t recognize the place name but when I saw the pic, I thought “Ohhhh, Gulfoss!” I have this exact pic … minus the stars … and the Milky Way … and the aurora … and the snow. But I have a lot
Thanks! My camera is pointed roughly south. It was shot on a Nikon d600 with a samyang 24mm 2.8 and a ioptron star tracker to prevent star trails. It took two images, one with the star tracker enabled and one with it turned off
I know what you mean, I’m always concerned for an astronaut when I seem them vulnerable like this. And when you really think about it, spacewalks for humans make very little sense. Especially if it’s a scenario like the ISS where you have a
A flare is caused when the magnetic fields in the area reach a critical tension. This tension is caused by the positive and negative sides pulling on each other and when they give they release a flare. The one that happened right after this
As someone who used to (I don’t really know what it is… Ghetto fishing?), I can more than sympathize with the water feeling. Basically, we lived on a decent sized lake. Every night we would drop fishing lines off the side of the pier
From my understanding, it’s shifted, either upward or downward. It’s certainly not true color, but in some tones it is. Color is merely the particular bandwidth of absorption or refraction of white light caused by how different elements and particles hit different wavelengths of
Well, honestly, who cares about what religion has to say about it. The fact that this kind of vastness exist just further reveals how petty and irrelevant man made religions are. I would also argue that science would suggest that, under the right conditions,
Yeah! I know, it seems most of my friends have been unaffected, but even out in Lubbock it’s flooding like crazy! like, whahaaaat! Flooding aside, that’s such a great representation of the texas sky, I wanna go back there. Texas pride is so real,
I was trying to get some of this tonight too but nothing anywhere near this. Spectacular! What were your settings?

I love pictures line these. Gives you a sense of scale of objects in the sky. Makes you realize you’re just on a spinning rock among millions of similar spinning rocks in a huge whirlwind among billions of other whirlwinds in a huge cloud
