My glasses say not to use them after 12 months

Perfect, you won't be using them in 12 months if you donate them now!

This seems like an incredibly poor idea as they are covered in labels saying not to use them if they are scratched, nicked or folded.

Is astronomers without borders a real thing? Is this just a troll? I feel like astronomers would know this.

Do you mean those one cent cheapass glasses that were probably manufactured in asia and SA to begin with? It seems like the cost of storing and transporting them would be more than simply printing new ones and shipping them in sheets. Virtue signaling feel good bullshit

Here's the high resolution image straight from NASA

I wish I could zoom in more but the pause button gets in the way. Thanks reddit.

This might be my favorite video of the eclipse. Space photos and videos that include an element of man-made technology in the shot are extremely intriguing. What a great shot.

Have you ever been to the cloud district? Ah.. nevermind.

I live very near to the Lake District! Definitely one of the most beautiful places in the uk, would recommend any tourists to take a visit!

Oh, what am I saying, of course you don't.

I'll have you know there is no PUSSSIEEEEEE

Passing clouds and the Milky Way

Do you have any more footage? That is beautiful!

Not sure if OP is actual OP or someone else but here is the imgur users page with plenty extra to look at.

What equipment was used and how was that done? It's so awesome.

Solar eclipse on Mars.

Its mass isn't large enough for gravity to push it into hydrostatic equilibrium.

What a stupid moon.

Considering how much smaller the sun would appear from Mars really puts how tiny Phobos must be into perspective. Also, what are the odds that the sun and moon would be almost a perfect size match from from our perspective?

They won't be the same size for ever. The moon is slowly moving away at a rate of around 3cm per year, and in around 600 million years the moon will be too small to cover the sun. The coincidence is that we're alive at the point when the moon is at this distance.

Edit: 3cm, not 1cm.

As the solar eclipse draws near, lets just take a moment and appreciate how far we've come in terms of observation technology by comparing the first image of the Sun (1845) and one of the most recent ones (2015)

I'm still more impressed by the picture on the left. How the hell did they do that in 1845?

Photoshopping skills have also increased (referring to the addition of color).

Many people don't even realize the color and added effects to space photos.

The sun's natural color in the visible spectrum IS white, and afaik that would also go for any star (though some may appear "tinted" a different color depending on the energy level).

However, it's not so boring as "give this a pretty color to dazzle the commoners." Typically the more interesting colors are displays in the visible spectrum of light outside the visible spectrum (like the photo of the sun on the right is likely infrared, but you can also have images reflecting a star's x-ray, UV, gamma, microwaves, etc.). So it's not what we'd see with our eyes, but the light does exist.

Please correct any of this if it's misinformation.

I tried to use my 105mm macro lens to shoot the Milky Way. It turned out pretty well!

Thanks for checking out my post! I took this a week or so ago during the perseids meteor shower before the moon rose and was amazed by the detail I could capture. I was inspired to try using my Sigma 105mm f/2.8 Macro Lens after my success shooting with a 50mm f/1.8 lens. However, the f/2.8 gave me a bit of a challenge. In combination with the lens being 105mm, I couldn't use a long exposure and my resulting photos were very dark and noisy, requiring me to use ISO-12800 (thanks D500!). In order to reduce noise a good amount, I experimented with stacking images in Photoshop. This result is a combination of 14 that I shot.

Each of the 14 frames was taken as a burst using a Nikon D500 and a Sigma 105mm f/2.8 macro lens at 3", f/2.8, and ISO-12800. In Photoshop, I stacked the images, did localized curve adjustments, saturated and desaturated to minimize color noise, dodged and burned, and color corrected. Here is what a single frame looked like prior to editing. In the future I would like to shoot more frames to bring out even more detail.

Also, I will be in rural Wyoming until late Monday afternoon and will not be able to answer any questions until then. Sorry about that.

its actually pretty easy once you understand the 3 main parameters. shutter speed, aperture and ISO

where he says f/2.8 that is the aperature, basically the round blades that open and close on the lens to let more light in.

where he says 3" that is how long the shutter was open for (3 seconds thanks /u/dtreth), also lets more light in, but at the cost of camera blur if not on a tripod. (for star photography you can also get star lines from the earth movement)

When he says ISO 12500. ISO is basically the sensitivity of the sensor in the camera, also for letting more light in, however the higher the ISO, the more risk of a grainy picture. So its better to get more light from the 2 mechanical options first.

As a noob, I still have no idea how you got from A to B

"Earth? That place? Oh man. It's just a bunch of apes beating each other with rocks. It's an unremarkable planet, really. They have come up with some interesting philosophies, but their technology is so outdated that it's a miracle we even saw that they were there. Radio waves. Can you believe it? Their politics revolve around two or more sides arguing as to whom is the most incorrect. Their economy is based on capital and trade, and they've got like one guy who even knows what an interdimensional portal gun even is. I'll bet you 300 flurbos that they will nuke themselves before they ever even notice us."

That looks like one of those golden age sci-fi novel covers come to life. Just needs like a big gas giant planet with rings in the sky.

"That rocket is landing itself, and I still struggle with parallel parking. Shit."

This photo is already in the most up to date history books.

Awesome stuff. Especially the pale butt crack.

NASA: "We're Going to Try and Make Oxygen From the Atmosphere on Mars"

NASA: "We're Going to Try and Make Oxygen From the Atmosphere on Mars"

NASA’s had plans for this since 2014, when it first revealed the Mars 2020 Rover. It involves bringing some microbial life to Mars, perhaps bacteria or algae, that would would use Martian soil as fuel and then pump out oxygen as a product. The oxygen could then be harnessed and made available for breathing and also to make rocket fuel for return flights to Earth.

That's basically the idea from the movie Red Planet. And that's in 2000.

That movie ended well...

Edit: what the hell reddit. This. This gets 1100 updoots? Really?

Finding alien bugs that produce oxygen and are the key to terraforming Mars?

Sounds like an ok ending to me.andafewpeoplediedbutwhoscounting

So in a couple hundred years or so, when mars has built up its Atmosphere and developed its own weather, would it basically be heavy snow storms?

From the edge of the Solar System, Voyager probes are still talking to Australia after 40 years

From the edge of the Solar System, Voyager probes are still talking to Australia after 40 years

I think it's unfair that Australia hold a monopoly on communicating with Voyager.

As an Australian it is my legal duty to go against you! We demand a monopoly... please.

That said it feel it is my duty to visit the site in Canberra in my life time. That and the parks observatory.

Alright to help answer your question, there's a NASA page for both Voyagers that tells you real time data of the distance, as well as how long it'll take to receive information from start to finish, which is roughly over 19 hours latency! Which is also 19 light hours away from us too! The more you know!

What kind of latencies does Voyager have coming in from the edge of the solar system?
