Maybe for you but I’m built different.

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

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.

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

There goes the real estate market.

Pronell, (edited ) do astronomy w A NASA mission that collided with an asteroid didn't just leave a dent. It reshaped the space rock

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.

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.

I dunno about giant. Looks pretty small from here.

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 wish they had links to the full res in the article. Annoying to have a “stunning image” but it’s only a 1080x1080 jpg

Tiltinyall, do astronomy w Huge star explosion to appear in sky in once-in-a-lifetime event

The last reoccurrence was after 80 years in 1946, I wonder why they are expecting it 2 years early?

Annoyed_Crabby,

They did said “80 years or so” and “around 80 years”, maybe they did their calculation and predicted that this year is likely the time that it happen. They did give a huge margin of when it will happen though.

0v0,

According to Wikipedia:

In March or April 2023, it dimmed to magnitude 12.3. A similar dimming occurred in the year before the 1946 outburst, indicating that it will likely erupt between April and September 2024.

I love that “recurrent nova” is a phrase.
