MeanEYE, w A Nearby Star Is Expected to Go Nova This Year. Here's How You Can See It.
@MeanEYE@lemmy.world avatar

So, there’s nothing in universe that is longer than “soon”. This prediction of going nova this year, only means it already happened but you can’t see it yet. And since it’s going super nova, that means entire even will be boring anyway. You’ll see a white dot that will increase in intensity during this year and then fade away equally slowly.

For people wondering about dates, there are none. Just like Beetlejuice is expected to explode soon™, that actually means 3000-10000+ years of waiting. So don’t get your hopes up. Out lives are but a blink in universe. All you can do is be diligent and watch it constantly. Doesn’t mean you’ll see much either since at peak magnitude of 2.5 it will be dim enough that you’ll need telescope to see it.

XeroxCool,

Nova, not supernova. Novas happen multiple times. Supernova do not but it doesn’t say supernova. Soon, as in within the next 6 months since its following a cycle that happened about 80 and 160 years ago.

nulluser,

Visible with unaided eyes for several days (but still dimmer than about 120 stars in the sky), and with binoculars for about a week, according to NASA.

stockRot,

Did you read the article? Or do you just like talking?

That is fascinating, I want to know, is there any way to prevent this during assembly? Even with extreme clean room protocols! Does it happen with other telescopes?! Down the rabbit hole, I must go.

Too much blood in their head because of zero g?

1024_Kibibytes,

The article suggests something similar:

“As gravity loosens its grip, blood, lymph and cerebrospinal fluid drift from their usual locations and begin to exert pressure elsewhere.”

I rarely get headaches. Haven’t really ever gotten any headaches throughout my life.

EddoWagt,

Same, maybe 1 or 2 really mild ones, that were just kind of annoying for a minute or so

Leg,

Here I am getting migraines so bad I contemplate self- terminating on a monthly basis. Life can be cruel.

EddoWagt,

My mom gets that as well, seems awful

aStonedSanta,

I get migraines or just started too. But never get head aches. Migraines for me just make light too overwhelming to look at but it isn’t pain. It’s almost confusion it causes me.

exocrinous,

I’ve never gotten a headache in space.

Bro, I don’t even need to go anywhere. In fact, I’d rather be in a dark room lmao.

Sekrayray, w Most Astronauts Get ‘Space Headaches.’ Scientists Want to Know Why

They mention this in the article, but the physiology would suggest this is related to CSF/blood pooling in low G.

Taking it a step further, I bet this has a similar mechanism to IIH or the high pressure headaches you get with obstructive hydrocephalus. CSF is supposed to drain down via a relatively passive system. Without G to regulate this I can envision that you’d essentially develop the same physiology as someone with IIH (too much CSF).

Really interesting. A good example of how we have no idea what insane health things we are going to experience with space travel, but also how space travel may shed insight on treatments for other conditions with similar mechanisms we experience in a gravity well.

ieatpwns,

Haven’t this is interesting because I’ve always wondered how evolution would happen when we finally colonize in low g environs. Maybe char was on to something when he said our souls are weighed down by gravity.

First symptom of space madness

ringwraithfish, w Most Astronauts Get ‘Space Headaches.’ Scientists Want to Know Why

If Constellation on Apple TV is right, then it’s an indication that the person has become quantum entangled with their alternative self in another universe.

Good show btw if you are looking for something more psychological with a sci-fi background.

A minor accident had forced me down in the Rio de Oro region, in Spanish Africa. Landing on one of those table-lands of the Sahara which fall away steeply at the sides, I found myself on the flat top of the frustum of a cone, an isolated vestige of a plateau that had crumbled round the edges. In this part of the Sahara such truncated cones are visible from the air every hundred miles or so, their smooth surfaces always at about the same altitude above the desert and their geologic substance always identical. The surface sand is composed of minute and distinct shells; but progressively as you dig along a vertical section, the shells become more fragmentary, tend to cohere, and at the base of the cone form a pure calcareous deposit.

Without question, I was the first human being ever to wander over this . . . this iceberg: its sides were remarkably steep, no Arab could have climbed them, and no European had as yet ventured into this wild region.

I was thrilled by the virginity of a soil which no step of man or beast had sullied. I lingered there, startled by this silence that never had been broken. The first star began to shine, and I said to myself that this pure surface had lain here thousands of years in sight only of the stars.

But suddenly my musings on this white sheet and these shining stars were endowed with a singular significance. I had kicked against a hard, black stone, the size of a man's fist, a sort of moulded rock of lava incredibly present on the surface of a bed of shells a thousand feet deep. A sheet spread beneath an apple-tree can receive only apples; a sheet spread beneath the stars can receive only star-dust. Never had a stone fallen from the skies made known its origin so unmistakably.

And very naturally, raising my eyes, I said to myself that from the height of this celestial apple-tree there must have dropped other fruits, and that I should find them exactly where they fell, since never from the beginning of time had anything been present to displace them.

Excited by my adventure, I picked up one and then a second and then a third of these stones, finding them at about the rate of one stone to the acre. And here is where my adventure became magical, for in a striking foreshortening of time that embraced thousands of years, I had become the witness of this miserly rain from the stars. The marvel of marvels was that there on the rounded back of the planet, between this magnetic sheet and those stars, a human consciousness was present in which as in a mirror that rain could be reflected.

-Antoine de St. Exupery

Just so you know, you’ve got me reading Wind, Sand and Stars now. Thanks!

It’s so good

niktemadur,

Well that is some spectacular prose, I am truly transported to a place where spirituality and science meet at a single point of grand mystery and realization that I have felt a few times in real life, alone in nature at surprising places and odd hours, but Saint-Exupéry has taken this all one further level up the rung.
To a level that my father actually lived, as an airplane pilot in Baja California back when the peninsula didn’t have a paved road, an isolated, remote place as yet mostly untouched by man.

One minor caveat, however:

a sheet spread beneath the stars can receive only star-dust

While I understand such a thoughtful writer was going for a feeling, surely with his talent he could have found a way to include windstorms, all the dust and sands they can sweep horizontally across the lands and over hills. The Rio De Oro region is in northern Morocco, surely it often gets blasted by powerful Saharan winds.
A sheet spread beneath the Moroccan sky most often receives desert-dust.

I suspect it receives relatively few big rocks from anywhere else though

Glowstick, (edited ) w Northern lights predicted in US and UK on Monday night in wake of solar storms

Anyone got a map? Saying “as far south as the midwest” is a pretty useless descriptor of where this might be seen

EDIT

Krrygon,

Thanks for posting the map! Looks like here in central washington, I am out of luck haha. Better luck next time, I s’pose!

Glowstick,

The red line is the “view line” so you might see a glimpse way off on the horizon

stoy,

I have the Aurora Pro app on my iPhone, it sends me alerts when the forecast predicts northern lights in my area (around stockholm)

Shdwdrgn, w Northern lights predicted in US and UK on Monday night in wake of solar storms

But the solar flare was yesterday, if there was going to be any good viewing of auroras it would have been last night, or more likely a couple nights ago (from US time zones). The peak of it occurred shortly after lunch yesterday and it’s calmed down back to normal today.

mihnt,

I mean, these are highly funded government agencies reporting this from both sides of the planet. You know something they don’t?

Shdwdrgn,

The agencies were correct about the information, however unlike OP apparently I know how to adjust for time zone differences. Monday morning in Australia is still Sunday in the US, so yes that would have been the correct time for the warning. But this article was posted here a day after the event occurred, all of the warnings expired, and the Kp index had dropped back down to more moderate levels. At the peak of the event the Kp index reached around 8.0. When I posted my comment yesterday it was sitting at 1.66, well below the threshold for seeing auroras anywhere in the continental US. If you had any chance of seeing auroras here it would have had to be Sunday night, not Monday night.

Complete cloud coverage predicted in UK, as per usual, until perhaps June.

It feels like this has happened a fair few times this year. Is the sun entering a period of heightened activity?

xantoxis, w A Mysterious Impact Left 2 Billion Craters On The Surface of Mars

~ Mysterious ~

I guess it’s true that we don’t know exactly what kind of rock hit the planet and created 2 billion craters from ejecta.

On the other hand, that makes every impact on every planet ~ mysterious ~

clickbaity.

Thorry84,

In true clickbait fashion the article then goes on to describe in detail said mysterious thing. Almost like it isn’t mysterious at all.
