To shreds spaghetti you say?

onlinepersona, do astronomy w Researchers identify effective materials for protecting astronauts from harmful cosmic radiation on Mars

Not sure if this belongs here, a physics, or a tech community 😅

This works here but maybe also in shitjustworks/c/spaceflight too. Or lemmy.world/c/space. Those are both pretty active space communities.

threelonmusketeers,

Instance agnostic links: !space and !spaceflight.

ekZepp, do astronomy w Scientist performs the first nonlinear study of black hole mimickers
@ekZepp@lemmy.world avatar

A nonlinear study refers to an approach that does not follow a straight, sequential path in analyzing or modeling phenomena. Instead, it allows for complex relationships where changes in one variable do not directly correspond to changes in another, often leading to unpredictable outcomes. In the article, a Princeton scientist explored the nonlinear dynamics of boson stars, a type of black hole mimicker. His research revealed unique gravitational wave signals during mergers, distinct from those of traditional black holes, which could aid in identifying these mimickers in future gravitational wave observation

And we found the MVP. Cheers to you, mate, and your explanation, thanks!

Lookorex,

I would also like to thank you for that

crawancon, do astronomy w Using small black holes to detect big black holes

Internet has me so jaded I did NOT think this was science related…

onlinepersona,

What did you think it was about? 😅

MindTraveller, do astronomy w Astronomers discover two new Milky Way satellite galaxy candidates

Is dark matter just dwarf galaxies?

btaf45, do astronomy w Astronomers discover two new Milky Way satellite galaxy candidates

If the distribution of those nine satellite galaxies across the entire Milky Way is similar to what was found in the footprint captured by the HSC-SSP, the research team calculates that there actually may be closer to 500 satellite galaxies

WTF? I was thinking there were around a dozen or so.

They solved one conundrum just to find another. Too few dwarfs then too many.

Drunemeton, do astronomy w New Type Ia supernova discovered
@Drunemeton@lemmy.world avatar

Does that exactly the same sentence in the first two paragraphs indicate an AI writer?

I stopped reading at that point.

maculata, do astronomy w How NASA's Roman mission will hunt for primordial black holes

I don’t think there are many black holes in Rome. But I suppose they really want to make sure.

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

I wonder if there’s a way to get an alert or something so I don’t miss it. I tried searching for one but so far no luck.

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

I love that “recurrent nova” is a phrase.

XeroxCool,

Novas can recur. Supernovas cannot

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.

WWJD, do astronomy w Stunning James Webb images show birth and death of massive stars

Janus coming for us

huginn, do astronomy w Stunning James Webb images show birth and death of massive stars

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
