showmeyourkizinti, w Astronomers find massive supernova remnant closer than previously thought

Ok so from what I can understand it blew off approximately a million years ago, and now it’s about 8.8k ly away. But where was it in relation to earth when it exploded?

BaroqueInMind, w Astronomers discover an ultra-massive grand-design spiral galaxy

Putting on my sci-fi hat; a distant galaxy that is likely a billion years older than ours, very likely has had enough time to develop life somewhere in the trillions of stars that formed within it, by the time the photons of that galaxy finally reached us and hit that very specific telescope sensor at that very specific moment the JWT engineers were observing.

Using the James Webb Space Telescope (JWST), an international team of astronomers has detected a new grand-design spiral galaxy as part of the PANORAMIC survey. The newfound galaxy, named Zhúlóng, is extremely massive and appears to be the most distant spiral galaxy identified so far. The finding was detailed in a paper published December 17 on the pre-print server arXiv.

Grand-design spiral galaxies are characterized by their prominent, well-defined arms, which circle outwards from a clear core. It is assumed that the arms in such galaxies are actually overdense regions of the disk which trigger star formation as incoming material is compressed in that region.

“We found aliens! Wait no, it’s actually just us again…”

SynopsisTantilize,

We should just bio-seed a planet just to see what happens. Like really …what’s the worst thing that could happen? (Genuinely asking)

Cause the way I see it, we could very well create a new planet or asteroid or moon with micro life on it. It would be nifty.

XeroxCool,

The worst that could happen in our lifetimes, I would say, is be a total waste of money and resources since no other reachable bodies have atmospheres suitable for Earth-based life. Beyond our lifetimes, and possibly beyond humanity’s existence, that life may be able to survive somewhere but any kind of evolution likely takes millions of years and long-term survivability may not let it see that day

Mbourgon,

Odds are we already have: Mars, Venus both have had landers, and given that the protections from bringing bacteria are similar or worse than this lander, the only reason bacteria would not have survived is due to heating of the landers in atmosphere. IANARocketScientist.

Fortunately, we found this out now, before we drop a red hot lander through the ocean surface of one of the moons of (I can’t remember) which they suspect could have life

I was just out enjoying Jup & Mars … couple hours too late for Ven … maybe it’ll be clear tomaro nite!

It’s not where I am sadly, cloudy all night looks like but on the 24th my next clear day but if it’s clear where you are Venus should be visible with the naked eye from about 16:00

it would be interesting to unlocking why this cycle happens and if its somehow linked to the dyanmo of the sun

NuraShiny, w Atmospheric analysis shows Venus never had Earth-like life, scientists say

Well duh. It’s a hell of acid storms and sulfur, how would it have had life?

HubertManne,

I mean sulfur is an important component of life and extremeophiles can handle many conditions. When I heard things about possible life at venus it was generally the idea of microorganisms floating in the atmosphere.

TheWolfOfSouthEnd,

I’m not meaning to sound sarcastic or like I’m taking the piss, but how do we know there are no life forms that like acid storms and sulphur?

NuraShiny,

This headline says earth-like life. I just didn’t repeat the word.

huf,

there’s a bunch of life around the deep sea volcanoes that lives off sulphur and stuff, so technically it’d still be earth-like life :)

NuraShiny,

Fair point there!

acockworkorange,

Even if it doesn’t have now, it’s quite a leap to say it never had.

NuraShiny,

Is it? Why?

acockworkorange, (edited )

Earth was very inhospitable for life for quite some time. In the future, it could become barren again. What’s to say that Venus wasn’t once harboring life? We don’t know anywhere near enough of its geology to even guess that.

Bronzebeard, w Heliophysicists call for fresh missions to study the Sun—and a new name for the field

Who wrote this shit? You can’t make an article that’s half about wanting a new name for your field and end it with “there’s a lot of ideas” without giving a single one. Garbage.
