Centaurus As Warped Magnetic Fields via NASA https://ift.tt/3tEgws2
When galaxies collide -- what happens to their magnetic fields? To help find out, NASA pointed SOFIA, its flying 747, at galactic neighbor Centaurus A to observe the emission of polarized dust -- which traces magnetic fields. Cen A's unusual shape results from the clash of two galaxies with jets powered by gas accreting onto a central supermassive black hole. In the resulting featured image, SOFIA-derived magnetic streamlines are superposed on ESO (visible: white), APEX (submillimeter: orange), Chandra (X-rays: blue), and Spitzer (infrared: red) images. The magnetic fields were found to be parallel to the dust lanes on the outskirts of the galaxy but distorted near the center. Gravitational forces near the black hole accelerate ions and enhance the magnetic field. In sum, the collision not only combined the galaxies’ masses -- but amplified their magnetic fields. These results provide new insights into how magnetic fields evolved in the early universe when mergers were more common.

I took this on March 20th, 2021 in Ontario, Canada. It’s my first go at any kind of astrophotography!

Let’s blow it up! An inflatable space station concept which actually made it to production, is inspected, May, 1961. This model, which never launched, was 30 feet & expandable & meant to be taken into outer space in a small package & inflated once in orbit. It was intended to house 1-2 people. It certainly doesn’t look too comfortable; I hope there’d be portals for viewing & sunlight but I can’t spot any in this photo. It looks like a giant inner tube.

HOW DOES TIME WORK IN SPACE??
Blog#81 Wednesday, April 21st,2021
Welcome back,
We customarily consider time something straightforward and crucial. It streams consistently, free of all the other things, from the past to the future, estimated by clocks and watches. Throughout time, the occasions of the universe succeed each other in a methodical manner: pasts, presents, future. The past is fixed, the future open ... but the entirety of this has ended up being bogus. What we call "time" is a perplexing assortment of constructions, of layers. Under expanding examination, in ever-more prominent profundity, the time has lost layers in a steady progression, piece by piece.
Let’s begin with a simple fact: Time passes faster in the mountains than it does at sea level.
Tumblr media
The difference is small, but it can be measured with precision timepieces that you can buy on the internet for a few thousand dollars. With practice, anyone can witness the slowing down of time. With the timepieces of specialized laboratories, researchers can detect this slowing down of time between levels just a few centimeters apart: A clock on the floor runs a little more slowly than one on a table. It is not just the clocks that slow down: Lower down, all processes are slower. Two friends separate, with one of them living in the plains and the other going to live in the mountains. They meet up again years later. The one who has stayed down has lived less, aged less, the mechanism of his cuckoo clock has oscillated fewer times. He has had less time to do things, his plants have grown less, his thoughts have had less time to unfold. Lower down, there is simply less time than at an altitude.
Tumblr media
Is this surprising? Perhaps it is. But this is how the world works. Time passes more slowly in some places, more rapidly in others. The surprising thing, perhaps, is that someone understood this slowing down of time a century before we had clocks precise enough to measure it. His name, of course, was Albert Einstein. The ability to understand something before it’s observed is at the heart of scientific thinking. In antiquity, the Greek philosopher Anaximander understood that the sky continues beneath our feet long before ships had circumnavigated the Earth. At the beginning of the modern era, the Polish mathematician and astronomer Copernicus understood the Earth's turns long before astronauts had seen it do so from the moon.
Tumblr media
In the course of making such strides, we learn the things that seemed self-evident to us were really no more than prejudices. It seemed obvious the sky was above us and not below; otherwise, the Earth would fall down. It seemed self-evident the Earth did not move; otherwise, it would cause everything to crash. That time passed at the same speed everywhere seemed equally obvious to us. But just as children grow up and discover the world is not as it seemed from within the four walls of their homes, humankind as a whole does the same. What's going on now in a far-off place? Envision, for instance, your sister has gone to Proxima b, the as of late found planet that circles a star around 4 light-years from us. What is your sister doing now on Proxima b?
Tumblr media
The lone right answer is that the inquiry has neither rhyme nor reason. It resembles asking, "What is here, in Peking?" when we are in Venice. It has neither rhyme nor reason, since, supposing that I utilize "here" in Venice, I'm alluding to a spot in Venice, not in Peking.
On the off chance that you ask what your sister, who is in the room with you, is doing now, the appropriate response is generally a simple one: You take a gander at her, and you can tell. On the off chance that she's distant, you telephone her and ask what she's doing. Yet, be careful: In the event that you take a gander at your sister, you're accepting light that ventures out from her to your eyes. That light sets aside some effort to contact you — suppose a couple of nanoseconds, a minuscule part of a second. Thusly, you're not exactly seeing what she's doing now yet the thing she was doing a couple of nanoseconds prior.
Tumblr media
On the off chance that she's in New York and you telephone her from Liverpool, her voice takes a couple of milliseconds to contact you, so the most you can profess to know is the thing that your sister was up to a couple of milliseconds prior. Not a huge distinction, maybe.
What's the significance here, this "alteration of the design of time"? Definitely, the easing back of time portrayed previously. A mass hinders time around itself. The Earth is a huge mass and hinders time in its area. It does so more in the fields and less in the mountains, on the grounds that the fields are nearer to it. This is the reason the companion who stays adrift level ages all the more gradually.
Subsequently, if things fall, it is because of this easing back of time. Where time passes consistently, in interplanetary space, things don't fall — they drift. Here on the outside of our planet, then again, things fall descending on the grounds that, down there, time is eased back by the Earth.
Tumblr media
Thus, despite the fact that we can only with significant effort notice it, the easing back of time by and by has vital impacts: Things fall as a result of it, and it permits us to keep our feet immovably on the ground. In the event that our feet cling to the asphalt, it is on the grounds that our entire body slants normally to where time runs all the more gradually — and time passes more gradually for your feet than it accomplishes for your head.
Does this appear to be unusual? It resembles when watching the sunset, vanishing gradually behind removed mists, we abruptly recollect that it's not the sun that is moving but rather the Earth that is turning. Also, we imagine our whole planet — and ourselves with it — turning in reverse, away from the sun.
COMING UP!!

12 Cosmic Baby Concept Patterns
12 Cosmic Baby Concept Patterns
Cosmic Baby Ideas That statement of giving your child the moons and stars can never be truer for this round-up. Cosmic Baby Patterns. A handful of ideas such as non-scary alien stuffy to a UFO to a rocket ship hat to name a few. Maybe a rocket ship blanket in C2C or a simplistic solar system mobile. The baby sweater with the UFO is really awesome. Truly. I’m a fan of Star Trek and so some of my…
