I lost Gill to a particularly aggressive form of ovarian cancer and the symptoms were mistaken for dietary issues combined with more exercise than normal (she was doing a lot of walks and yoga so overlooked the weight loss). For any of my female followers looking in do note the symptoms below πŸ‘‡

Two tawny frogmouths perched on a palm tree branch. Both have large, bright orange eyes and fluffy facial feathers, and they stare directly toward the camera while sitting side-by-side.

Presented here is an animation of the supernova remnant SNR J0509.5-6731 expanding over time. It appears to be moving at close to 2% of the speed of light. It is around 163000 light years distant, so it has to move quite speedily for us to be able to witness its movement on a human timescale. The first frame is from 2006, and the second is from 2016. The video shows the two frames blinking back and forth to make the motion easy to see.

Note that only the narrowband (seen here as the red, smooth outline of the nebula) was available to show the nebula's expansion. The star field is essentially a static image, though the narrowband data did also capture some star movement, particularly the bright star to the left of the frame. The Chandra data was simply scaled up to match with the expansion of the shell in the Hubble data.

a dalmatian with small brown spots all over sits up and smiles up at you with a goofy open-mouthed grin and sparkling light brown eyes. he is wearing a white plush unicorn horn, and he’s balancing beautifully on one front paw. both his ears are inside-out, but he doesn’t have a care in the world.

I wonder if you’ve had a chance to view the Mission Impossible episode β€œEncore” (S6E2)? As i recall, lots of #TOS tie-ins, and a rare role as a badguy by M. Shatner.

You know what makes me sad?

Future generations growing up accustomed to AI-generated images will absolutely doubt all the amazing and weird animals that I find delightful: precisely because they look so unreal.

New study about how that shithole Twitter skews your thinking because it feeds your brain conservative views (this is a feature that has been fine tuned, this is not a bug).

It not only takes your brain to the bad place, it’s harder to come back from it.

Go show your comms teams still using it.

The two middle adults are in an aggressive stance facing up to each other red beaks open the right one leaning in with his flippers flung back. The adults on either side of which only heads and a small amount of bodies showing appear to be  joining in 2 with their beaks o0pen as well as if shouting The chick is looking at the two aggressors and is standing on one leg with its fluffy down covered flippers outstretched at each side

I’m sharing this in recognition of Gladys Mae West’s work on GPS because it’s been a transformational technology for archaeology and that lady deserves to be lauded.

Per other coverage, the method was used to try to circumvent a ruling pertaining to a previous attempt at cheating in, uh, well… the same general area.

I’ve asked this before in all seriousness: How do we nominate the Internet Archive as a UNESCO World Heritage Site? How do we protect it as a cultural resource of global importance, especially now?
