DIY Potion and Spell Book Tutorial from Better After.This is a really good tutorial using plastic toys, glue gun, cardstock and paper towels. This FIY is based on a tutorial by SEEING THINGS - my favorite Halloween Blog that had great printables and tutorials and is now DEAD & GONE. This is why if I see a printable I like, I don’t wait unitl later to download it.
~This would also be a nice tutorial for an actual spell book instead of just a decoration.
The effect shown in the gif is called gravitational lensing.
What is gravitational lensing?
Gravitational lensing is the effect seen when an object behind a massive object is in the line of sight with the earth. For example:
Earth ————>Massive Object—————->Far away object
When we try looking at the far away object, the massive object bends space-time around it, causing the light rays from the far away object to travel in a curved path around into our line of sight.
As a result of this, we can often see the far away object magnified which helps astronomers understand the early universe. The gif shows a far away galaxy being gravitationally lensed by a closer black hole.
Mysterious hot spots observed in a cool red supergiant
Astronomers have released a new image of the outer atmosphere of Betelgeuse – one of the nearest red supergiants to Earth – revealing the detailed structure of the matter being thrown off the star.
The new image, taken by the e-MERLIN radio telescope array operated from the Jodrell Bank Observatory in Cheshire, also shows regions of surprisingly hot gas in the star’s outer atmosphere and a cooler arc of gas weighing almost as much as the Earth.
