On a trip last week to estate park of castle Duivenvoorde and took the opportunity to pester some dragonflies. Single shot 1/640s EOS 400D in 300mm/f4.0 lens.
Frontal closeup of red dragonfly perched diagonally on what seems to be rough barren terrain but is actually just the top of a molehill. The front of the dragon fly is in focus showing details such as veins on the wings the abdomen behind is blurry to due to depth of field at large aperture.

I just feel like so much of how people talk about consequences for rapists just reveals the poverty of imagination and lack of understanding of how ill-equipped the criminal justice system is to handle something like rape

View of Saturn from last night 🔭🪐 #Astrophotography #Astronomy
Telescopic view of Saturn. Saturn centred, surrounded by featureless darkness. Saturn appearing as a large brown-ish disk, subtle banding is apparent on the planet, notably a dark band just below the equator. The rings can be made out crossing the disk, and with the Cassini Division on the left and right edges.

260 years ago, on the 2nd of October 1766, ‘Cheese Riots’ broke out at the Nottingham Goose Fair after Lincolnshire merchants had bought large quantities of cheese with the intent to sell it back home. The residents of Nottinghamshire did not want food to leave their county. #otd #history 🗃️

The two #Equinox are the only days when the Sun rises due East and sets due West, everywhere. At the Dec solstice the sun rises in the S-East. At the June solstice it rises in the N-East. As the days pass between the two, the sunrise position slowly changes passing due East each equinox.🤩 🔭🧪

Anyway TL;DR a "sex cult" is a cult that weaponizes sex and has sex at the core of its rituals and exploitative dynamics. A cult where people are sexually exploited is just... a cult. Sexual exploitation is everywhere.

I reconnected with and met some really great people in London and Paris. But there’s a reason I haven’t been to Europe in nearly a decade. The utterly ignorant, arrogant and racist things I heard and observed.. always hits different for me in Europe. Even with all of my “African American privilege”.

guys the UK gender clinics -𝕝𝕚𝕥𝕖𝕣𝕒𝕝𝕝𝕪- required trans people to use the facilities for their target sex, for two years, before they were given any access to healthcare. rationale is not where these people go looking for answers. it is solely about their bigoted priors. everything comes after that.

It's a popular astronomy cliche that there are more stars in the universe than there are grains of sand on all the beaches on Earth. Hard to visualise that, of course, but look at these two images with very different fields of view... Mind-blowing, right? And very beautiful too, I think...
