Viewed close up, a tiny frog sits on a dirt road road. Illuminated by an out-of-frame headlight, the frog’s green markings are quite vibrant.
Nocturnal Frogger 🐸
We’ve heard a chorus of these Pacific tree frogs almost every night since we moved, but they are surprisingly hard to see most of the time. An apparent exception to that rule is when they’re all hopping across the road to congregate in our seasonal ponds and puddles to lay eggs.

Also constantly blown away by how these cockroaches operate.

Bernhard Riemann's 1854 habilitation lecture introduced the idea of a manifold with a smoothly varying positive-definite metric tensor—well before the formal definition of tensors existed.

A high‑resolution overhead view of a rocky, desert‑like landscape on Mars. The surface is mostly reddish‑brown with patches of darker blue‑grey tones. Many circular impact craters of different sizes are scattered across the scene, some with raised rims and shadowed interiors. Subtle ridges, eroded valleys, and textured terrain patterns run diagonally through the image, giving a sense of ancient geological activity. The overall impression is of a dry, rugged, and heavily cratered Martian surface.
Craters, craters, and yet more craters! Our latest snapshot from Mars Express is packed full of them.

Two images of a planetary nebula in space. The image to the left, labelled “Euclid & Hubble”, shows the whole nebula and its surroundings. A star in the very centre is surrounded by white bubbles and loops of gas, all shining with a powerful blue light. Farther away a broken ring of red and blue gas clouds surrounds the nebula. The background shows many stars and distant galaxies. A white box indicates the centre of the nebula and this region is the image to the right, labelled “Hubble”. It shows the multi-layered bubbles, pointed jets and circular shells of gas that make up the nebula, as well as the central star, in greater detail.

WOH G64 is one of the biggest #stars in the universe, with a radius 1,500 times larger than that of our sun. And scientists think it might be getting ready to #explode. If we're lucky, we could see this star go out in a massive #supernova within our lifetimes. 💥🌌🔭

A tiny portion of the Rosette Nebula. Very dark gray material shaped like a shark’s fin extends from just below top left all the way down to the lower right corner and back up toward the top right. It looks like thick smoke that has billowed out irregularly, thicker along the line from top left to bottom right. Behind the dark gray on the left side, from the bottom left to top center, there are streaks that appear light orange and yellow. The background at top left is hazier and some blues are covered in semi-transparent orange wisps, which makes sections take on green hues. In the bottom right, the background is bluer. There are a few bright red and purple stars scattered along the right half, mostly toward the bottom. The largest star is at right-center, just at the edge. It is red and has four diffraction spikes.
In 2024, #Hubble observed a portion of the Rosette Nebula—a vast star-forming region located 5,200 light-years away. Hydrogen, oxygen, nitrogen, and dark clouds of dust contribute to this mesmerizing scene, which is four light-years long: https://bit.ly/4rndjuB

A white, glowing egg-shaped object lies in the centre of the black-and-white image, on a dark, starry background. Glowing streaks spread upwards from the object. In the top left, a yellow arrow marked ‘Sun’ points straight down, and a blue arrow marked ‘Velocity’ points towards the 7 o’clock direction. In the bottom left, an inset shows the same object on a lighter grey starry background, filled with ragged-edged, concentric egg shapes gradiented black-to-white.

There is a paradox at the heart of Solar Orbiter.
On one hand, we wanted to take the closest ever images of the Sun. On the other, the closer we'd go, the more damaging the light we sought to collect would become.
