I have a few watches, kinda collect them. Not being familiar with this particular watch I asked my jeweller if he knew of them and he said he’d never heard of them.🤔

The Betelgeuse watch tells you when it’s SHOWTIME!

they started looking for tachyon particles (faster than c) and they're *still* looking for them.
I personally think the theory is daft.

But if there's a boundary between sub-light and faster-than-light activity, it makes sense that we wouldn't be able to detect tachyons, at least not directly -- perhaps indirectly by inference?

Perhaps, indirectly. That's *if* they exist

It could have already gone nova or supernova. 600 ish light years from Earth it could have already gone nova a hundred years ago and we still won't find out for 500 years.
Have there been any indications of life-supporting planets in the system?

Or is that a planet-less system?

I think it is a wee hot, some 1000 degrees C.

"While no single planet is definitively the "most likely" to support life, promising candidates include K2-18b, which has shown atmospheric evidence of molecules linked to life, and the rocky, Earth-sized planets in the TRAPPIST-1 system, such as TRAPPIST-1e, that orbit within their star's habitable zone. Other strong contenders include Kepler-186f, which is similar in size to Earth and was one of the first discovered in a star's habitable zone, and Proxima Centauri b, a rocky planet orbiting in its star's habitable zone.
Promising candidates for supporting life
K2-18b:
A sub-Neptune planet that is about nine times the mass of Earth and is located in its star's habitable zone.
The discovery of molecules in its atmosphere, such as dimethyl sulfide, has led to reports of the "strongest evidence yet" for life on a distant planet, according to CBS News and CBS News.
TRAPPIST-1 system:
A system of seven Earth-sized, rocky planets orbiting a cool dwarf star.
TRAPPIST-1e is considered one of the most promising, as it is similar in size to Earth and orbits within the habitable zone, the region where liquid water could exist on the surface.
Kepler-186f:
The first Earth-sized planet discovered in the habitable zone of another star.
It orbits a red dwarf star and receives about one-third the sunlight that Earth does, placing it on the outer edge of its habitable zone.
Proxima Centauri b:
A rocky planet orbiting the star Proxima Centauri within its habitable zone, meaning it has the potential for liquid water if it has an atmosphere.
It is the closest-known exoplanet to Earth, located just over four light-years away.
Kepler-452b:
Discovered in the habitable zone of a star similar to our Sun.
It is about 60% wider than Earth and is considered the most "Earth-like" exoplanet found to date, based on its star and location.
Factors to consider
Habitable Zone: A planet must be in this zone to potentially have liquid water, a key ingredient for life as we know it.
Atmosphere: An atmosphere is crucial for maintaining liquid water and protecting the surface from radiation.
Rocky composition: Rocky planets, like Earth, are considered more likely to support life than gas giants.

Thank you for taking the time to compile and post that. I figured you might know something about the topic.

Sorry that I forgot to include "life as we know it" 😉 -- but yeah, even from a Terran layman's perspective in 2025, I can understand that there must be a complex of relevant limits involved when it comes to the possibility of other lifeforms.

Of course in my previous post I was wondering: wouldn't it be horrible (and perhaps chastening) for the people of Earth to obtain clear evidence of sentient species existing in that system just before it went "Blammo!" ? 😉

(c.f. also a certain story by Sir Clarke)

On Mars I would not be a bit surprised if they find something like mold or mushrooms or some such, of course after humans are there and can go all around the planet to collect specimens.
The latest Mars discovery was found by one of the orbiters, a small hill not much bigger than a tennis court shows signs of recent water flow, of course any liquid water flowing on mars with 1% of our atmosphere would have to be very briny to remain liquid but now they have recent evidence, by recent I mean in the past few years not millions of years ago.



I would love to see a flyby of Europa flying through one of those water jets shooting off the moon combined with a sample return. They think there might be life under the surface in an ocean some 20 miles deep and the tidal heating heats up the interior to allow liquid water.
So maybe we won't need to fly 20 light years away or even 4.3 LY to Alpha Centauri, which would be MY choice for a first visit, kind of like our first shot outside low Earth orbit was the moon because it was a bit noticeable for the entire time of humanity and protohumans so it was a natural first choice for a visit to another planet.
So maybe the same thing will affect our solar travel.
AC would be my first choice simply because besides being 'only' 4 LY away, you get a nice 3 for 1 shot, since it is a triple system, maximum 0.1 Ly apart and one planet has just been nominated to be possible Earth like, sitting in the goldilocks zone. News at 11🙂

@Paul-Martin The issue, according to special relativity anyway, is that as an object with mass approaches the speed of light it's mass will become infinite. It would therefore take an infinite amount of energy to accelerate beyond the speed of light, which is impossible.

For first time, scientists see the very early stages of a supernova

The researchers used the European Southern Observatory's Chile-based Very Large Telescope, or VLT, to observe the supernova, which involved a star roughly 15 times the mass of our sun residing in a galaxy called NGC 3621 about 22 million light-years from Earth in the direction of the constellation Hydra. A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km).

FIRST CONFIRMED SIGHTING OF EXPLOSIVE BURST ON NEARBY STAR

https://www.esa.int/Science_Exploration/Space_Science/XMM-Newton/First_confirmed_sighting_of_explosive_burst_on_nearby_star

Astronomers using the European Space Agency’s XMM-Newton space observatory and the LOFAR telescope have definitively spotted an explosive burst of material thrown out into space by another star – a burst powerful enough to strip away the atmosphere of any unlucky planet in its path.


so long,
and thanks for all the fish

This promoted me to see if any of the bookies are offering odds, but can’t find anything.

If anyone can, it would be fun to see what odds you could get for a tenner on it going supernova in the next year.


(Edit: nod to @sonhouse comment that it is 640 light years from earth so it’s already historical in that respect)
So how much money on which date?
