I like this quote:

“The problem is that electric cars are popular with politicians precisely because they provide an excuse to avoid doing harder things, like rebuilding our cities, or changing the habits of lifetimes. Persuading people to switch from their old gasoline car to a shiny Tesla is much easier than persuading them that they can live without a car. Hence governments are pushing electric cars, often with incentives that make no sense.” - Daniel Knowles, author of Carmageddon

This will hopefully be visible - An ancient comet that hasn’t been visible from Earth for over 50,000 years will become visible in Australia from 2 February spaceconnectonline.com.au/disc

A #Mastodon #Space #Quiz! #Mars robotic exploration is how many years old?

(Brought to you by a talk I just attended by Jim Green!)

Sometime ago I became interested in the history and philosophy of the positron and its antimatter siblings - a second Phd didn't go the distance. However here is part of that thesis that got squelched by academic publishing, I am still proud of the effort: almostlucidthoughts.blogspot.c

Computer science pioneer and United States Navy rear admiral Grace Hopper was born #OTD in 1906.

As far as I’m aware, she is the only person who has both a supercomputer and a US Navy destroyer named after her.

The Sun, our star, this morning in the light of excited calcium ions. Highlighting the active regions and large scale plasma convection cells, the magnetic fields on the Sun are spectacular

The Sun is up on a beautiful Saturday morning and I am nearly ready to start observations 🌞🔭

My favorite solar image of the day

A spectacular image from today - it has it all (OK not really spectacular sunspots) AR 3152 in the upper RH (north eastern quadrant of the solar disk), great filaments in the southern hemisphere, gigantic prominence visible off the south western limb, flares off the south eastern limb - zoom in this image has amazing detail! More images from today to follow but this was just a beautiful example of why we observe the Sun.

Images taken from a cloud free Albert Park in inner Melbourne. Lunt130MT scope on an iOptron CEM70G mount and ZWO ASI174MM camera. H alpha images (656.5nm) Lunt double-stacked 130mm etalons. Images captured using Firecapture, and processed in AutoStakkert!3, RegiStax6 and Photoshop.

Rather pleased with my image of the Sun taken in Ca II K light (393.4nm). It gives a fascinating view of the active regions (AR3147 clearly visible near the Sun's eastern limb) and plasma convection cells

Taken with a 130MT scope and ASI174MM camera, at 20221118 _001621 UT. Images processed using !3 and coloured in

Almost there! The #Orion spacecraft captured these selfies while flying through space on the way to the #Moon. During the #ArtemisI flight, the Orion capsule will fly past the Moon, and return to #Earth up to 42 days later.

Getting a nearly 100 year old telescope at the Melbourne Observatory ready for viewing the Sun. The reflector has it's aperture stopped down and a Baader film cap attached
