The term "astronomical" is used to describe longshots for a reason.

 :D :D :D

Anyway, I was just reporting interesting things.  We've all been watching the 'geuse for a few years now, waiting to see what may have already happened but we won't see for 300 or 400 more years.  (that's off the top of my head.  I'm not sure of its distance, I just know it's not exactly close.  It's just luminous.  Google at will, captains lol)

Interesting... but how big was said asteroid?  It must have been pretty small not to have been noted otherwise...

Really small, 2m, disintegrated above Arctic Ocean north east of Iceland.

Yes, it's our galaxy.

Imaged in neutrinos.

Darned wonderful! We live in an age of horrors and wonders.

That's pretty neat. I had no idea neutrino observations were precise enough to use for a map. But is there any way to get the "depth" of the picture with neutrinos?

VLBIB - Very Long Baseline Iceblocks ;) The size of the ice detector gives it the resolution tanks of dry-cleaning fluid can't match. Now if Arctic ice, or even Greenland, was remotely stable, you  could do it there. But ...

Bad news about Trappist;

So, the Trappist-system was very promising in that it has several Earth-like (in mass) worlds in the habitiable-zone. But, after studying the first two worlds, Trappist 1b & 1c, it's concluded that they have a very thin atmosphere, if any at all.

https://www.nature.com/articles/s41586-023-06232-z

So, red-dwarfs, because for planets to be in their habitable-zone, they have to orbit close, but, so close, that,  stellar-winds can interact with their atmospheres and with them being tidally-locked, they may lack a magnetic-field. In most cases, the host-star would have blown the atmosphere off of the planet.  Trappist 1b has virtually no atmosphere and Trappist 1c, has, well, an atmosphere probably thinner than Mars, whereas, we expected a Venus-like atmosphere;  now, granted, both these worlds are super-close to the star, and the system is, in fact, 5.4 to 9.8 Billion years-old; even that much time, stellar-winds could reduce an atmosphere.

What this means for Battletech: M-Class stars might just be recharging stars for jumpships; pirate-points in which there are not habitable worlds in the system. This is also really, really great news for the xenophobes out there, in that, red-dwarfs, being the most numerous-stars, are hostile to life as we know it, which, reduces that chances of running into an intelligent E.T.  The only known planet orbiting a red-dwarf with life on it is Proxima-Centuari B (home-world of the Grays). 

They still haven't analyzed all the worlds in the HZ yet, so, at least the closest worlds may lack an atmosphere for red-dwarfs. 

Here's an obligatory image thereof:

That's true in the solar system, much less the Universe!  8)

Some (who have digging tools) might argue it's true on Terra...  ^-^

To be fair under current system generation rules the chances of an M-Class star hosting a habitable planet - without lots of Fiat - are already ... fairly low. As in one in a couple thousand or so. Too lazy to run the numbers.

It should be noted for Trappist-1b that the atmosphere observation only has a 1-sigma reliability for 0.01 bar, i.e. under evaluation of the observation there's a 32% chance that it is denser than 10 millibar. Mars' atmosphere for comparison has about 6 millibar.

And Chandrayaan-3 is on it's way to the moon with a clean takeoff from Satish Dawhan Spaceport ...

https://www.bbc.com/news/live/world-asia-india-66199759

I like the look of the GLSV-3 launch vehicle, and that's a very nice clean liftoff. Let's hope the software deficiencies which caused Chandrayaan-2 to lithobrake last time are fixed!

NASA's Juno spaceprobe has seen its orbit adjusted in order to perform more science regarding the Galilean Moons.

Today I have brought a link to an article about Jupiter's moon Io, with brand new images and observations.

A relatively new theory known as Modified Newtonian Dynamics (MOND) attempts to explain the motion of low velocity binary star systems, something that neither traditional Newtonian physics nor Einstein's theory of General Relativity have been able to explain without resorting to Dark Matter.  And as we know, Dark Matter leaves unsightly stains as well as a nasty aftertaste, so this is a good bit of scientific reporting.

As I understand it MOND struggles with observations of dark matter not being co-located with regular matter. So while I'd love to see some new physics I doubt we'll see it. :(

It's a theory, it can be proven wrong easily.  But it's better than using something we have no evidence for in place of actual measurable substance - as is the case when we plug so-called "dark matter" into the equation.  When asked about what dark matter is, most reputable astrophysicists will give a fairly long answer that ultimately boils down to "not sure".

But it’s not a good theory if it gives the wrong answers...  Which is - as I understand it - what it looks like at this time.
