Ice Without Gravity

Astronaut Don Pettit is back in space, and that means lots of awesome microgravity experiments. Here, he grew thin wafers of ice in microgravity in a -95 degree Celsius freezer.  (Image credit: D. Pettit/NASA; via Ars Technica; submitted by J. Shoer) Read the full article

Sag A* and it's Magnetic Properties

Sat at the centre of our Milky Way galaxy, lies a supermassive black hole over 4.5 times the mass of our sun. On 12 May 2022 Event Horizon having already taken the very first image of a supermassive black hole in M87, turned it's attempts to peer through 25,000 light years of dust and gas to grab the first image of our very own galactic monster, and since has continued it's work to produce the above image showing the magnetic lines coming from it.

The same work had been undertaken with M87 previously, and what Scientists have found is, essentially both show very similar structures.

Why is this important ? It's the first indication that the physics at work in these black holes are almost the same, despite the difference in size between them, with M87 being 5 billion times the mass of our sun.

But how can they know about this ?

It's all down to polarized light, the magnetic fields change the way the light reaches us, and so, we can map this and create these detailed images of how the fields flow within the light.

The light itself is not directly from the black hole, that's at the centre, but it's an accretion disk of material that flows around it, and is distorted by gravity to look as above.

Woitschikowski works only when he’s relaxed. “When you’re stressed,” he says, “you cannot see pictures,” such as this one of ascorbic acid, or vitamin C.

Polage is a unique artform that combines polarizing sheets and cellulose to create a shifting color pallet when viewed via polarized light with a rotating filter. The light changes orientation as it passes through the various layers of plastic, a process that occurs on a molecular level. Polarization allows for the refraction of a specific spectrum of light frequencies (ie, colors).
