Heartbreaking

This is what astronomers like @sundogplanets now have to contend with and it is only going to get worse...

Astronomy Picture of the Day

Comet R3 PanSTARRS Behind Satellite Trails
Image Credit & Copyright: Uli Fehr

Explanation: Can you find the comet? Somewhere through this web of satellite trails is Comet C/2025 R3 (PanSTARRS), a bright visitor passing through the inner Solar System. Now, the orbiting satellites themselves only appear as streaks...

@mastodonmigration That's really something else seeing it like this, and not in a good way.

@PamelaBarroway @sundogplanets

Yes. It is really stunning. We are blinding ourselves.

@mastodonmigration @PamelaBarroway One (Nazi) billionaire, ruining an entire planet's view so he can have more money than God. What a awful shitlord.

@mastodonmigration @sundogplanets it's deeply cynical that one of the major culprits calls itself "Space Exploration Technologies Corporation"

[corpsmoderne@mamot.fr]

@mastodonmigration @sundogplanets ok don't get me wrong: satellites pollution is a big problem and people should be made aware of it.

But as an astrophotographer I know that the software we use are very good at removing them, usually without rejecting the whole frame.
This picture has been processed specifically to emphasize the problem, which is a tidy bit misleading even if for a good cause.

Amateur astronomy is not the problem with swarms of satellites.

Will still share it.

@corpsmoderne @mastodonmigration @sundogplanets

As a scientist who did process data from various professional telescopes, I know that you can hide these trails and still make "nice" pictures. But I also know that by doing so you degrade the signal, and when what you are looking for is at the detection limit (it usually is, otherwise you would not waste precious telescope time on it), it can introduce artifacts or hide valuable info.

@deneb @mastodonmigration @sundogplanets oh 100% . I was strictly speaking about amateur astronomy, I'm sure it's a very different problem in professional astronomy. But the picture above belong to the amateur kind of photography.

@mastodonmigration I can find the comet, but that doesn't ameliorate the fact that these bastards have filled our near orbit with shit. @sundogplanets

[leonardof@bertha.social]

@mastodonmigration @sundogplanets for an instant, I thought the post would be about mansplaining

[viennawriter@literatur.social]

@mastodonmigration @sundogplanets @Susticle That's what I meant the other day ...

[juergen@fedifreu.de]

@mastodonmigration @ichwillechtnurlesen @sundogplanets Looks like a sewing pattern. But I found the comet.

[steveclough@metalhead.club]

@mastodonmigration @sundogplanets I can find the comet. But that is not the point - this is major level pollution of our skies.

Something that is more and more of a problem, because there are so few places left where you can get a decent view of the sky because of ground pollution, and are accessible, so that amateurs and kids and families can actually see the sky as it really is, and get excited about astronomy.

But even these places are now being polluted by LEO satellites.

[cattail@mastodon.social]

@mastodonmigration @sundogplanets that has to be a sunset/sunrise phenomenon. If it was the middle of the night the sun would be behind the Earth and the satellites would be in shadow unless they're really low on the horizon

[flaubau@gay-pirate-assassins.de]

@mastodonmigration
@sundogplanets

not doubting at all, just curious, why do the stars not turn into stripes as well? does it take longer than 10 minutes for this to happen?

i know very little about astronomy

@mastodonmigration @sundogplanets@mastodon.social

And this is how it looks like after psychopath musk lift up 1 mio of his satellites.
