homesweethomeMrL, in Spiral galaxies like the Milky Way are surprisingly rare. Astronomers may finally know why.

A computer simulation says spiral galaxies on a plane bang into each other and result in more elliptical galaxies. Ours hasn’t banged into anyone else yet, that the computer simulation knows about.

bdx2023,

… So that infamous impending collision with Andromeda will take our spirals away?!

(Impending in a cosmological sense, so several million years at least IIRC)

Trabic,

Thousands of millions of years I think, and continuing for at least hundreds of millions before the bouncing stops

Actually our galaxy has had at least 1 other collision according to our current understanding.

But our spiral likely formed after.

Downvoted for click-bait title.

… I think more importantly mars needs oxygen

So desert plant life plus desert bugs equals terraforming capable species?

Because humans introducing species to new environments always goes well 😩

That’s neat!

“It’s amazing. It’s like a little treasure trove that takes us back to the start of the solar system,” said Dr Ashley King, a planetary scientist who will work on the grains at the museum. “I can’t wait to get my hands on them and see what we can learn about the early solar system.”

well, nothing yet.

notfromhere, in SpaceX rockets keep tearing blood-red 'atmospheric holes' in the sky, and scientists are concerned

This article is a big nothing burger.

Player2, in SpaceX rockets keep tearing blood-red 'atmospheric holes' in the sky, and scientists are concerned

‘scientists are concerned’ and ‘atmospheric holes’ implies something a bit scarier than a short light phenomenon to me, bad headline

Cethin,

Bad headline for the consumer, good headline for the increasingly shitty fear-based media that is trying to get you to click.

Rozz, in SpaceX rockets keep tearing blood-red 'atmospheric holes' in the sky, and scientists are concerned

…not a threat to humanity

Well that’s good at least

JohnDClay, in Moon’s scientifically important sites could be ‘lost forever’ in mining rush

Here’s a great video by Cody’s Lab on the subject. Namely, there could be frozen microbes from Earth’s distant past in the permanately shadowed craters since the moon is so much more stable than earth.

JackGreenEarth, in Astronomers discover six planets orbiting a nearby sun-like star

‘nearby’

100ly away.

Pons_Aelius, (edited )

In space that is nearby.

If we scaled the milky way to the size of earth, that would be about 15km away.

If we scaled the observable universe to the size of earth that would be about 4mm away.

“Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.”
― Douglas Adams, The Hitchhiker's Guide to the Galaxy

btaf45,

100 ly years is actually kind of far. It is farther than most of our named stars. I wouldn’t consider it ‘nearby’.

Pons_Aelius,

In space that is nearby.

That was my point, Human scale vs astrophysical scale.

btaf45,

100 ly is not in our local intersteller neighborhood. It is 3x farther than even Arcturus.

Good thing I never said it was.
