Idontevenknowanymore, w James Webb Space Telescope Finds Stunning Evidence for Alternate Theory of Gravity - The Debrief

I understood about 8% of that article but it’s still fascinating.

Deconceptualist,

I follow this stuff (as a non-physicist) so I understood it. It’s a pretty shallow article and mentions there there’s still evidence for the widely-accepted Lambda-CDM model. But like most coverage of MOND it declines to give good alternate explanations for specific key observations like the Bullet Cluster, gravitational lensing, and galactic outer rotational speeds.

So yeah a new observation that fits better with MOND than LCDM is certainly interesting, but it doesn’t flip the tables unless it does a better job explaining the prior phenomena too.

Idontevenknowanymore,

I understand the two theories and the difference between them, but when my brain tries to comprehend how gravity actually works I experience a comprehension failure.

Deconceptualist,

Haha, well if it’s any consolation, nobody fully understands it. That’s why we’re still looking at various theories of quantum gravity or even random gravity.

vzq, w Roman Space Telescope reaches assembly milestone

When your space program delays are so massive that your empire hasn’t existed for 1500 years, but your payload is still in the assembly stage.

Nancy Grace Roman

She may be elderly, but she’s not quite that ancient :)

kemsat, w Nearly three years since launch, Webb is a hit among astronomers

Oh damn, I thought it’d be tennis players that were gonna be into the space telescope.

FooBarrington,

That doesn’t even make sense. If anything it would obviously be Baseball players.

NigelFrobisher, w Telescope with world’s largest digital camera will be a ‘game-changer’ for astronomy

This will be able to take the most detailed pictures of Uranus yet.

I wish it said more about the camera sensor; guess I’ll have to look that up separately

slazer2au, w Telescope with world’s largest digital camera will be a ‘game-changer’ for astronomy

Here’s hoping starlink and similar Space junk doesn’t mess it up.

dudinax, w NASA Reveals Prototype Telescope for Gravitational Wave Observatory

Wow it’s tiny

Telescope is almost a misnomer here. It will be “looking” at other satellites, not astronomically distant objects.

The influence of gravitational waves will be seen in changes in the relative distance to each of the six satellites.

threelonmusketeers,

Yes, but also no.

Each side of the triangular array will measure nearly 1.6 million miles, or 2.5 million kilometers.

The satellites themselves may be small, but the interferometer antenna they’ll collectively form will be huge.

sinkingship, w Brought my Celestron NexStar 6SE out on a camping trip last weekend and pointed it at the moon

Ah, this is probably the right community to ask.

What are those stripes leading to the crater, here in the upper left?

I’ve noticed them before, but when I try looking it up, I usually only find results for Saturn’s moon.

Beautiful picture, op!

ns1,

Not an expert but I’d guess that is Tycho crater, and the stripes are called its ray system en.wikipedia.org/wiki/Ray_system

sinkingship,

Interesting, thank you for the reply! Learned something new today. The lines I see span over a quarter or so of the moon, so I’m not fully convinced yet. Absolute massive.

that celestron sure is a powerful flashlight!

acockworkorange,

Daaaaaad

Imhotep,

oh shit, it already started

Nice photo!

Looking at the moon is always fun.

Somewhen in there are creatures we’d really get along with were it not for the 58.71M light years between our galaxies, and the unlikelihood we both exist as simultaneous civilizations.

Gloomy, w Event horizon: After photographing black holes, scientists are now making a movie
@Gloomy@mander.xyz avatar

They have quite big plans, but almost 14. Million € on hand. I hope they manage to achieve their goal.

We produce for the first time high-resolution multi-colour movies with the EHT combined with new telescopes probing the variable extremes of the electromagnetic spectrum (e.g. CTA, MeerKAT/SKA1). The data are analysed and interpreted with innovative models finally combining micro- and macrophysics. The PIs bring together complementary expertise over the entire black hole mass scale in radio imaging and multi-wavelength monitoring, astroparticle physics, and theoretical modelling to bear on the problem. This is accompanied by four major investments: construction of a new mm-wave telescope in Africa enabling full dynamical imaging of black holes with the EHT, new model development, supercomputing hardware, and a vibrant team of young scientists to help develop a new, truly universal black hole paradigm.

I find it fascinating that so much of astronomy is having data and trying to make educated guesses about what that data could maybe indicate. It shows just how much more there is to find out, realy.
