Jane’s stomach lurched — not to be sick, no. It was the anxious flutter of freefall she’d become intimately familiar with.

Falling up, really, but falling nonetheless. Floating was too nice a word for the terrible grip playing hockey with her viscera.

This time, though, there was no coffin of steel and glass to cage her in, just an endless expanse of darkness. That was far worse, she decided. At least in the car, she knew where she was. Where she was going. If she’d been spaced and left behind — would anyone find her? Would anyone come looking?

Thunk.

i tried to find armoured skeptic's really old flat earth debunking video, it came out in a time where it might've taken me into the anti-sjw cloud, but it doesn't seem to exist anymore. i remember it being really really unconvincing, like i think he claimed that the horizon would look flat from ANY elevation? somehow? and when the flat earther said there should be stellar parallax from earth's orbit mr skeptic basically said "no, there shouldn't be, because stars are billions of light years away" even though they are much closer than that and there is stellar parallax as a result. how do u fumble debunking flat earth

HOW DO WE KNOW HOW THE MILKY WAY LOOKS LIKE??

Blog#362

Saturday, December 30th, 2023

Welcome back,

This is the spiral galaxy NGC 2835, imaged by the impeccable, seemingly timeless Hubble Space Telescope.

And this is NGC 1132, an elliptical galaxy captured through the tandem efforts of Hubble and NASA's Chandra X-ray Observatory.

We know what both of these breathtakingly beautiful galaxies look like because we can see them from afar. How then do we know what our own Milky Way galaxy looks like, seeing as how we are inside it?

While we've never been able to zoom out and take a true galactic selfie, there are numerous observations that clue us in to the structure of our home galaxy. The greatest hint comes from looking at other galaxies. While there are perhaps two trillion in our observable universe, surprisingly, they only seem to come in three discernable varieties: spiral, elliptical, and irregular.

Spiral galaxies have a mostly flat disk with a bright central bulge and arms that swirl out from the middle. Elliptical galaxies tend to be round or oval with a uniform distribution of stars. Irregular galaxies are like stellar splotches in space, with little structure at all.

Gazing skyward from our vantage point on and around Earth, there are clear signs that the Milky Way is a spiral galaxy. You can see one sign with the naked eye! The Milky Way appears in our sky as a relatively flat disk.

Using more sophisticated methods, astrophysicists and astronomers have provided two more clues to the structure of the Milky Way.

"When we measure velocities of stars and gas in our galaxy, we see an overall rotational motion that differs from random motions," Sarah Slater, a graduate student in cosmology at Harvard University, wrote. "This is another characteristic of a spiral galaxy."

Moreover the gas proportions, colors, and dust content are similar to other spiral galaxies, she added.

Aside from these lines of evidence, astronomers are also using their tools in ingenious ways to map the structure of the Milky Way. Just this year, scientists used two radio astronomy projects from different parts of the globe to measure the parallaxes – differences in the apparent positions of objects viewed along two different lines of sight – from masers shooting off electromagnetic radiation in numerous massive star forming regions in our galaxy.

"These parallaxes allow us to directly measure the forms of spiral arms across roughly one-third of the Milky Way, and we have extended the spiral arm traces into the portion of the Milky Way seen from the Southern Hemisphere using tangencies along some arms based on carbon monoxide emission," the researchers explained. They coupled these observations with other gathered data points to construct a new image of the Milky Way. This is our home galaxy, in all its resplendant glory.

"WHAT IS QUARK MATTER??"

[klimkovsky]

Open star cluster Messier 6

Messier 6, also known as the Butterfly Cluster, is an open star cluster located in the constellation Scorpius. Here's what astronomers know about it:

Basic Information:

Catalog Designations: M6, NGC 6405

Location: Constellation Scorpius, near the stinger of the scorpion

Coordinates: Right Ascension 17h 40m 20s, Declination -32° 15' 00"

Distance: Approximately 1,500 to 2,000 light-years from Earth

Physical Characteristics:

Age: Estimated to be around 100 million years old, making it relatively young for an open cluster.

Number of Stars: Contains about 80 to 100 stars, with some sources suggesting up to 300 when including fainter members.

Brightest Stars: The brightest star is a class B8 giant, which gives the cluster its distinctive V-shape, reminiscent of butterfly wings.

Apparent Magnitude: The integrated visual magnitude of the cluster is about 4.2, making it visible to the naked eye under good conditions.

Morphology and Structure:

Shape: Its distinctive butterfly shape is what most observers note, especially through binoculars or a small telescope.

Size: The cluster spans about 25 arcminutes across the sky, but its actual physical size corresponds to roughly 12 to 15 light-years in diameter.

Scientific Interest:

Star Formation Studies: Open clusters like M6 are crucial for understanding star formation processes since all stars in the cluster are roughly the same age and distance from us, providing a snapshot of how stars evolve over time.

Chemical Composition: Observations of the stars in M6 help in understanding the chemical composition and evolution of stars within open clusters, particularly how metallicity varies.

Distance Calibration: It serves as a benchmark for calibrating distances in the Milky Way due to its well-studied parameters.

Observation:

Visibility: Best observed from the Southern Hemisphere due to its declination, but it's visible from the Northern Hemisphere in summer months when Scorpius is high in the sky.

Equipment Needed: Visible to the naked eye in dark skies, but binoculars or a small telescope will reveal its butterfly shape more distinctly.

Cultural Significance:

While not as culturally famous as some other clusters, M6 is part of the lore of sky watching, especially among amateur astronomers for its distinctive appearance.

Messier 6 was cataloged by Charles Messier in 1764, who included it in his list to help comet hunters distinguish between deep-sky objects and comets. This cluster, along with its neighbor Messier 7, offers a beautiful sight for anyone exploring the night sky in the direction of Scorpius.

Source: Grok AI

First, let's correct a few inaccuracies

Modern (and already quite accurate) estimates of the distance to the Messier 6 cluster are inclined to the value of 1600 light years (or a little less). Accordingly, the linear dimensions are limited to 12 light years.

The brightest star of the cluster BM Scorpii is a red-orange giant of the spectral class K3. Before the time when stellar parallaxes began to be measured directly from spacecraft outside the atmosphere, these measurements were made with a high error. Therefore, it was believed that this star did not belong to the cluster and was located twice as close to us - in the middle between the cluster and the Solar System. You can understand why everyone liked this idea: Most of the stars in the cluster are blue and hot, and this one is red and cold — as if from another stellar family.

But now everything has become clear

BM Scorpii is indeed a very massive star, exceeding the Sun in mass by about 17-20 times. And in the 120 million years that the cluster has existed, it has lived almost its entire stellar life. Now it has already entered the final stage of its evolutionary path, and in some future (in a few million years) it will flare up as a supernova, scattering the matter of its outer layers around itself, and will give the cluster a nebula of an unpredictable shape. And in place of the core of this star, most likely, only a neutron star, or even a black hole, will remain.

The open cluster Messier 6 can be visible to the naked eye. It is better to observe it in the southern hemisphere, since its declination is below -30 degrees — in the middle northern latitudes it either does not rise, or even during the upper culmination literally lies on the horizon. And to see it without optics, it needs to rise high in the sky (and, of course, the observer needs to be further away from city lights).

It is interesting to compare this cluster with the Pleiades — the brightest and most beautiful open cluster in the northern sky. The M6 "Butterfly Cluster" is four times further than the Pleiades. But if it were in their place, it could look no less impressive. In any case, its brightest stars would be 16 times brighter - this is approximately 3 stellar magnitudes brighter than the magnitude they have now, and this would be quite comparable to the brightness of the Pleiades stars.

It is quite possible that this cluster was seen in ancient times by Ptolemy — in the second century AD (although this is only an assumption). And the first documented observation of the Messier 6 cluster dates back to 1654 and belongs to Giovanni Battista Hodierna.

John never invited her anywhere nice, Jane thought, watching the lava rivers gurgle and burp across the landscape as they landed. Well… that wasn’t entirely fair, was it? Maybe he’d invited her somewhere pleasant once or twice in the many emails she’d sent straight to digital hell. The last place she’d actually accepted had been to an iceball masquerading as a ski resort where she’d almost frozen her toes off and all their friends had died. All the furniture she and Palaven’s newest Primarch desecrated and-or broke in his private suite afterwards couldn’t quite salvage that one.

Just once, it would be nice if he invited her somewhere with white sand and clear water and banger margaritas and no potential loss of life or limb.

PERCIVAL "PERCY" FELIGUIRE

Age: 19 He/Him Bisexual

After studying a forbidden evolution of Chi in his world, he eagerly went to show it off to the others in his village. Horrified, his village cast him out, ashamed of the darkness he was researching, regardless of how revolutionary it could be if it was utilized.

Lost, frightened, and without a home, Percy continued to hone his skills until he was able to open a rift to another world. With nothing left to look back upon, he stepped through into a new dimension.

After awhile, he settled down in a new village- until the Parallax Plaguebringers came a long and blew a hole in the side of the mountain it was in. It was then that Charles, Firefly, and Stellar swooped in to put a stop to them, where Percy decided it might prove entertaining to join them in their journey...
