This is part of a featured story in Live Science abouf 30 days ago. Perseverance's view of the sun's far side will actually improve in the coming months as Mars becomes even more aligned with the side of the sun hidden from Earth, which will help the robot to track increasingly powerful storms...

Thirteen and a half days sure, as an approximation though this varies with latitude. I was wondering whether it was possible to know through the camera position if it was possible to accurately determine the sunspot location in the pics. That is whether the view of the sun is the same that we...

Maybe a little off topic but it was recently reported the Mastcams on the Mars rover Perseverance have detected a large sunspot on the far side of the sun. The story went it could impact Earth if it remained active once it turned past the East limb of the sun and faced Earth. Helioseismology at...

It began with the Big Bang and.... nature abhors a vacuum :blush:

https://www.forbes.com/sites/startswithabang/2018/02/10/ask-ethan-how-do-we-know-space-is-expanding/?sh=6633248649e6 The fabric of space-time is expanding at a constant rate, but the universe is expanding at the speed of light plus 67m/MegaParsec/s. So the bigger the universe gets, the more...

IMHO the Universe is expanding outwards at an increasing rate as evidenced by galaxies moving away from each other. Some researchers suggest this expansion may end in just 100 million years and a big crunch will take place where the universe will start contracting on itself. I keep an open mind...

Hello Harry Costas IMHO the Universe is expanding. T.A,

It does indeed :)

Southern Land from my reckoning. Do you have a different take on it? TA

Copy that :) Have a good day. Terra Australis :)

I didn't copy that! Say again. T.A.

Harry can you explain chiral supersymmetry please. I looked at this a little last year what is latest thinking? TIA, T.A.

Hello Helio, I picture photons shooting off in all directions, electrons whizzing around all over the place and soundwaves bouncing off the walls. Energy flows out of the system causing temperature drop, pressure drop and fusion to slow. What do you think? There is still so much more to...

Hi Pogo ... interesting! I also considered slicing the Sun into rings, like you might slice a pineapple. For every slice the rate of rotation at the core would be the same, however each slice would have a different rotational speed at the surface, Equator -> N & S Poles Is there is a...

To All,.. ... thanks for this discussion. I have read that the Sun rings like a bell. How much mechanical kinetic energy is transferred via soundwaves I wonder? T.A.
