I honestly don't think we make enough of this. We decided to reverse a trend of a century or more of birdlife dying out & with time and money and community we did it. There are *goddamn kiwi* in the back yards of my neighborhood. There are species we haven't seen in a century in & around Zealandia.

I will soon be interviewing candidates for this ~2-year role (22-23 months, actually, for reasons of grant arithmetic) if you are interested in studying auditory perception and music in adults with mild cognitive impairment or mild-to-moderate dementias, all over new zealand, please apply!

This is a photo of our home planet taken only a few hours ago! So what? We have photos of Earth taken from space every day. Ah, but *this* photo was taken by a spacecraft ON ITS WAY TO JUPITER.
From the source: "Mostly black space, most of Earth visible at the top right of the image. Part of a spacecraft visible on the left."

Unscheduled photo dump because I was treated on my walk to work today to two quite different "bird enjoys spring flowers" experiences. Tūī: "I shall delicately sip nectar yum yum" Kererū: "FEED ME FLOWER"
Tui reaches up to sip from a white blossomTui curls around a white and pink flower cluster, about to drink.kereru bends around a kowhai branch, about to snip a flower off with its beak.kereru attempts to stuff entire kowhai flower down its cavernous gob. It ate about another half dozen in the minute after I took this photo.

New Horizons is now *three days away* from shutting off its two heliophysics instruments, simply because NASA has not provided the $2M in funding it had promised to the mission last year or this year. There is no science basis for shutting these off. Our earlier coverage:

This is a quick workup of what the night sky might look like on a world close to the galactic core. The planet is a rendering by Martin Kornmesser, to which I added the JWST image. So this scene is suggestive more than scientifically accurate. But still... imagine growing up under a sky like this.
The fore- and middle ground shows a rendering of a rocky exoplanet surface. The JWST Sagittarius scene from the first post occupies the upper half of the image.

Sensors on a twin buoy out in the Atlantic Ocean send live satellite data to motors inside the museum. This makes the indoor buoy copy the exact, real-time movements of the ocean waves.

🧪⚒️ Interesting: modelling of length of day changes suggests that primary coupling between core and mantle is mainly a gravitational torque (dense bits of core and mantle attracting each other) rather than mechanical drag at core-mantle boundary or interaction with geomagnetic field.

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.🤩 🔭🧪

Happy 118th birthday, spacetime. 🧪 🔭 ⚛️ Hermann Minkowski addressed the 80th Assembly of German Natural Scientists and Physicians #OTD in 1908, offering a radical four-dimensional reformulation of Einstein's theory of special relativity. Here is how he opened his address.
"The views of space and time which I wish to lay before you have sprung from the soil of experimental physics, and therein lies their strength. They are radical. Henceforth space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality."

Extremely favorable dynamics have led to one of the largest (in area) ozone holes on record. However, thanks to gradual healing from the reduction of ozone-depleting substances, the actual amount of ozone loss is more typical of the long-term average. Would have been a really bad one 25 years ago!

In reporting this, I learned that Russia launched a big space mirror in the 90s. Retrospective pieces c. 2015 were like "what a crazy, supervillain-y idea!" Now the idea is back, being taken seriously, and shining light (sorry) on the shortcomings of space law. 🔭🧪 www.sciencenews.org/article/refl...
