Comparing the final two images of taken of earth in 1972 and 2026 respectively; does the 2026 (left) image look murkier and less crisp to anyone else?

Surely our camera gear is exponentially better now? Is the reason for the new image being ‘murkier’ due to light, pollution or something else?

> Surely our camera gear is exponentially better now

They are better, but not exponentially. You can't beat physics, film cameras can still compete in terms of dynamic range and resolution, the optical elements haven't changed that much. The 1972 photo was taken on medium format film, which is twice the size of the sensor area in the modern one, which means more photons and less noise. The recent image was take at a really high ISO, which adds to the noisiness.

1972 -> taken during daytime 2026 -> taken during nightime

Why is spectacular in quotations? I keep seeing this in headlines, is it because they're quoting a single word?

It’s a BBC journalistic standards thing; the BBC doesn’t want to express an opinion about the image, they are relaying that as a quote from someone about the image. The word “spectacular” is attributed to NASA in the article.

It's lazy "editorializing"

Quite the opposite.

Dear some very-rich person, please send a selfie-camera to the space! Yes, all that effort so we can keep looking at ourselves on a planet scale.

It sounds trivial, but perspective shots like this are part of why public support for space programs exists at all

Good news! We already have that! If you pay taxes to the US that's one of the thing you've helped pay for:

For reasons that are unexplainable if you're the NYTimes, polluting industries have been trying to kill these missions for decades.

I'm not a US resident but I'm immensely disappointed in myself because I didn't know this existed.

I guess the rich person who was just planning to respond to my request needs to find another thing to spend their money on :)

What is that bright star like object on the bottom right? Is it Venus? I’m guessing it’s Venus because it’s much brighter than a star would be.

NASA confirmed it is Venus, yeah.

Very cool. Along the same lines the EPIC::DSCOVR mission has been taking photos of the earth since, I believe, around 2015.

This picture wasn't taken from far away, but I thought about that quote from Carl Sagan -

Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every "superstar," every "supreme leader," every saint and sinner in the history of our species lived there-on a mote of dust suspended in a sunbeam.

The Earth is a very small stage in a vast cosmic arena. Think of the endless cruelties visited by the inhabitants of one corner of this pixel on the scarcely distinguishable inhabitants of some other corner, how frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds. Think of the rivers of blood spilled by all those generals and emperors so that, in glory and triumph, they could become the momentary masters of a fraction of a dot.

Our posturings, our imagined self-importance, the delusion that we have some privileged position in the Universe, are challenged by this point of pale light. Our planet is a lonely speck in the great enveloping cosmic dark. In our obscurity, in all this vastness, there is no hint that help will come from elsewhere to save us from ourselves.

The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand.

It has been said that astronomy is a humbling and character-building experience. There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known.

If you're confused what you're looking at, turn it upside down.

From the article:

> The Earth appears upside down

Which I find to be a rather interesting take.

The comparison pictures look like there is more dust in the air today. They don't explain this effect, so I assume it is related to time of day the photo was taken, or camera settings, not actual dust accumulation compared to 1972. However, the direct comparison gives the impression they want people to interpret like the air is getting dirtier?

Why is the old image so much more blue? Did pollution increase cause this change in color over time?
alex_duf 1 day ago|
One was taken during daylight on film, which needs to be processed and scanned, the other one was taken at high ISO during night time on a digital camera.

So much interpretation is done on colour on each step of the way that it's not surprising the colours are looking different.
