Spotted a line of Starlink satellites tonight. Super clear early evening

There were about 9 in a row whizzing across the night sky

Starship launch tomorrow, c.1300hrs our time.

They "appear to have lost it".

Finders Fee?

 

[Drago]

An astonishing spectacle.

 

[classic33]

A success!

Any other space geeks on here members of the Planetary Society?

"The Amaterasu particle has an energy exceeding 240 exa-electron volts (EeV), which is millions of times more than what particles achieve in the Large Hadron Collider, the most powerful accelerator ever built.

It comes only second to the Oh-My-God particle, another ultra-high-energy cosmic ray, which was detected in 1991 and possessed 320 EeV of energy."

Volts isn’t a unit of energy, be hey hoh.

Volts isn’t a unit of energy, be hey hoh.

...but electron-volts is.

 

[DCBassman]

"The electron-volt is a unit of energy or work. An electron-volt (eV) is the work required to move an electron through a potential difference of one volt. Alternatively, an electronvolt is equal to the kinetic energy acquired by an electron when it is accelerated through a potential difference of one volt."

...but electron-volts is.

I stand corrected 😁

The ISS has been passing over southern England the last couple of days. I’ve been sorting my camera gear, so took a big lens out to see what I could capture. It’s not exactly Hubble but at least it’s space station-shaped… 😊
