Pronell, (edited ) 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.

Thorry84, w The mathematically perfect exoplanet system — a great place to search for alien tech

Damn space.com, don’t forget to put some article in between the ads on your site

kat_angstrom, w The mathematically perfect exoplanet system — a great place to search for alien tech

Damn, the article never actually defined what they meant by “mathematically perfect” :(

The first link leads to an older article that does explain it. What they mean is that the planets’ orbits are in resonance, which means that their orbital periods are related by integer ratios. (For example one planet completing exactly three orbits in the time it takes another to complete two)

SpiceDealer, w Varda Capsule Reentry - Five Minutes from LEO to Earth
@SpiceDealer@lemmy.world avatar

Damn it! Misread Leo as Lego and got excited at the prospect of a fully functional Lego spacecraft.

That’s it? Doesn’t seem like much at all.

Nestlé is already building a rocket.

I call it a DPT, Digital to Physical Twin

This is astronomy?

I thought this was about an ISS Mimic. Like with teeth.

tunetardis, w Webb Discovers Methane, Carbon Dioxide in Atmosphere of K2-18 b - NASA

This is where it starts to get exciting. Up to this point in human history, we have had no firm evidence of life on another world even though speculation runs rife. It is always just beyond our reach to detect it, but we may soon collect enough bio-signatures to infer its existence with reasonable confidence.

Life on K2-18 b is still pretty unlikely. Or at least what we would call life… There have been signs of Dimethyl sulfide, which would be one of those bio markers.

Orbituary,
@Orbituary@lemmy.world avatar

I would say it’s neither likely or unlikely. It’d simply unconfirmed. We don’t have a solid baseline for establishing how widespread life is.

What we do know is that carbon and long-chain carbon molecules like methane are indicators. Nothing more.
