If it's not seen as much, that probably means the green material is heavier than iron. It's less common, but large enough stars can fuse even heavier elements. That's where all those elements on Earth came from in the first place.

I dunno about giant. Looks pretty small from here.

wtf is a “dark energy camera?” smh

This thing is just a mosaic of ordinary CCDs. I’m sure the name has something to do with it’s specific scientific goals, but that’s not explained at all in this article. They didn’t even attempt to make any kind of connection between the veil and dark energy. Or even between supernovae and dark energy.

Neat. Makes sense. An asteroid isn’t usually one chunk of rock but several chunks conglomerated.

You think you might break it up but you rearrange it instead.

At least that’s how my dumb ass read it.

Well, there goes that idea. I will have to look for other places to retire.

Did anyone ever think it was inhabitable?

The news is really interesting exobiology science, but the headline is terrible.

wintermute_oregon,

Yes. That’s been a theory even since I was a child in the 70’s. They don’t mean humans but life in general

Zaktor, do astronomy w Saturn's largest moon most likely uninhabitable

It feels like the title should be “uninhabited”. Life on earth doesn’t survive because we continue to be bombarded with nutrient carrying asteroids, it just needed them to kick it off. That few nutrients are likely to make it from the surface to the ocean means the genesis is unlikely to occur, but it doesn’t seem to make a decision about whether an unlikely genesis could survive, even if only in a small pocket of the ocean.

Wondering if Tancredi is related to this somehow.

Balthazar, do astronomy w An astronomer's lament: Satellite megaconstellations are ruining space exploration

Starlink is causing problems, but it seems to me that this image was made in bad faith to oversell the case. The caption says it’s a combination of 29 separate exposures, but if those exposures were combined properly, you wouldn’t see the satellites (median combination does wonders, and there are more sophisticated techniques which do even better). Some streaks start at one chip edge and extend to another chip edge, without continuity across the focal plane. So it’s not at all clear just how this image was created. And why on earth is it not flat-fielded? Maybe this is just really sloppy image processing, but even amateurs can do far better than this, leaving the final combination with no satellites at all.

You can just say Starlink, it’s the only one
