Stars go missing.

[DBT]

It seems that we have stars missing in action;

''There’s something odd happening in our skies. Almost 100 stars seem to be missing.

They haven’t gone nova. Nor have they become black holes. With no natural explanation available, some astronomers are seeing aliens.

In 2015, a group of citizen astronomers brought the world’s attention to KIC 8462852, which quickly became known as Tabby’s Star. It was flickering. Erratically. Dramatically.

It’s no longer alone.

Some 21 other stars have been found behaving in the same seemingly unnatural way.

But, in 2016, Swedish astronomers noticed nothing.

It was nothing where something was supposed to be.

A star had vanished.

Without a trace.

Three years later, they’ve discovered at least 100 more are missing.

“Unless a star collapses directly into a black hole, there is no known physical process by which it could physically vanish,” the study reads.

“If such examples exist, this makes it interesting for searches for new exotic phenomena or even signs of technologically advanced civilisations.”

WHO TURNED OUT THE LIGHTS?

The Stockholm University and the Institute of Astrophysics of Canarias have been following-up their 2016 nothingness in space.

Back then they were comparing a 1950s photo of the constellation Lupus the Wolf to a more contemporary image. The 1950s image showed a star. The new one did not.

But there was no plume of a supernova. No sign of a collapsing, cooling husk.

This wasn’t supposed to be possible.

But this particular impossible is becoming increasingly common.''

Wow, very interesting. It seems like a dyson sphere is very unlikely due to how much gravity assist it would take to keep the structure around the sun. Could be alien ships moving about. I'm sure that more research is coming on this.

In a universe which is 13.772 billion years old, it is not valid to declare the disappearance of stars "is becoming increasingly common" because of observations over a period of four years. This may be a regular occurrence, which we just noticed, or it maybe a cycle and these star will reappear some time in the future.

The Constellation known as the Pleiades is familiar to any stargazer. One of the first astronomy lessons anyone hears is about how the ancient Greeks called this star cluster the "Seven sisters" and the Native Americans called it the "Seven lost children". Yet, only six stars are visible to the naked eye. This mystery has fascinated humans since the first person looked up at night and said, "Wait a minute, there's only six."

The French artist William-Adolphe Bouguereau used this as the theme of his work, "The Lost Pleiades", although anyone familiar with Bouguereau's work will know he didn't really need a theme to produce his softcore oil on canvas paintings. For those interested in this intersection of science and fine art, a print of this painting is available on a tote bag.

They have not excluded Novas. I mean they say it does not appear to be Novas but that's clearly not enough.

There is a bit more informative article on these 'missing' stars here:
https://www.sciencealert.com/a-look-through-past-star-catalogues-finds-scores-of-stars-that-have-mysteriously-vanished
It offers several ideas that need to be examined before concluding that this is something extraordinary. A couple possibilities are that they could have been closer and dimmer than first assumed so moving faster with respect to the background stars than assumed... this would mean that they have just moved out of the image frame. Another is that the first image could have been made during a flaring stage and the star has since calmed down to a much lower magnitude so dropped below detection limits.

I did recently finish a computer programming task to print the hypothetical nine billion names of God, but it seems unlikely that this could be the cause.

When you find that most of your data points are bad data that generally means the rest are also. I doubt stars are going out.

 

[thebeave]

Maybe the telescope lens had a bunch of little shiny flecks on it that looked like stars, and then the janitor came along with his Windex and cleaned them off. It could happen.

It's not likely that stars are going out. The question is, what is happening?

They're probably in a pocket universe, while Davros makes his reality bomb. Someone should call the Doctor.

Spoiled like something is passing in front of the star. Is it across the spectrum or just in the visible?

Just heard this on a science segment, there is a star that periodical dims.

It would have to be something large and dark to block out a star for considable period of time. If it was something relatively closer to us than the star you would not expect it to hold position for long, or perhaps block out a larger area of light than a single star, yet there no dark patch in the starfield to suggest dark matter or gas.

The Sherlock Holmes approach. Delineate the possibilities and eliminate the least likely.

ET draining energy from another universe, possible but not likely. An unknown stellar process, a lot more probable. Something blocking radiation, also more likely.

The question is completely dark across the spectrum or just visible. IR?

No, it can't happen because these specks would be out of focus.

Presumably if the star was still visible in a different spectrum it would be a different issue, the star would not have disappeared like they say. I haven't had time to dig further, but surely they must have checked.

Nova can change brightness by a factor of million.

This may be an example of a failed supernova, a red giant collapsing relatively quietly into a black hole;

Failed Supernova
'''N6946-BH1 is a disappearing red supergiant star in another galaxy, NGC 6946, on the northern border of the constellation of Cygnus. The star was 25 times the mass of the sun, and was 20 million light years distant from Earth. In March through to May 2009 its bolometric luminosity increased to at least a million solar luminosities, but by 2015 it had disappeared from optical view. In the mid and near infrared an object is still visible, however, it is fading away with a brightness proportional to t−4/3. The brightening was insufficient to be a supernova, and is called a failed supernova.''

''After the idea that a black holes are usually formed after a supernova, N6946-BH1 has given evidence that, instead of following this process, the star may automatically collapse into a black hole.''

 

[steve_bank]

The news segment I saw said the stars initially were beginning to like a nova.

 

[steve_bank]

Could it be a Dyson Sphere?

Visible light goes away but the sphere would be an IR hot spot.

I can't imagine anyone actually building a Dysons sphere.
