Eyes on Hong Kong. A huge fire broke out in a set of high-density residential flats in Tai Po, with fire still spreading through the bamboo scaffolding.

🌲The town of Kōya is surrounded by mountains covered in forests. Small shrines can be found in the woods
The area is also full of insects and other invertebrates, here a small sample

🪦In Mount Kōya one can find Okunoin, the largest cemetery of Japan, where giant conifers stand next to thousands of tombs and a mausoleum. The place is also infamous for its revisionism in memorials to Japanese soldiers and officials during WW2

☸️Kōya is a small town in the mountains south of Osaka. Full of temples and monasteries, it serves as the headquarters of Shingon Buddhism and a pilgrimage destination. Many temples here are specialised in hosting visitors

Yesterday we had a special #MonkeyCruise stream in honor of Jane Goodall! Her contributions to primatology and our understanding of animal intelligence changed the worldview of whole generations and her caring and critical voice will be missed.

Chandra's Fall Collection 🍂

A quartet of images that invoke themes associated with autumn

1. NGC 6334 nebula: Cosmic leaves blowing
2. SNR G272.2-03.2: The Space Pumpkin
3. R Aquarii: A cosmic sweater
4. NGC 2207 and IC 2163: A pair of galactic cornucucopia

chandra.harvard.edu/photo/2025/f... 🔭🧪
For many, nothing evokes fall more than fallen leaves. In this view of NGC 6334, glowing pockets of dust and gas in the nebula resemble leaves that have been picked up by a wind gust. This region is actually home to strong winds blowing from the young stars that have formed there. This image contains X-ray data from Chandra (blue, green, and yellow) that shows the effects of these winds, which have been combined with infrared data from the now-retired Spitzer Space Telescope (red, brown), which shows the dust and gas that fuels the growing stars. Credit: X-ray: NASA/SAO/CXC; Infrared: NASA/JPL/CalTech/Spitzer; Image Processing: NASA/CXC/SAO/J. Schmidt Born after a violent explosion of a star, this cosmic gourd is the supernova remnant G272.2-03.2. X-ray observations (orange and magenta) from Chandra provide evidence that G272 is the result of a Type Ia supernova explosion, where a white dwarf star pulls material from a companion star until it triggers a thermonuclear explosion and obliterates the star. The inside of the “pumpkin” is superheated gas that is filling the space cleared out by the explosion as it moves outward. Credit: X-ray: NASA/CXC/SA0; Optical: NOIRLab/DECaPS2; Image Processing: NASA/CXC/SAO/L. Frattare Multiple telescopes teamed up to capture an image that looks like a cozy sweater with fuzzy arms. X-rays from Chandra and ESA’s XMM-Newton (purple), optical light data from Hubble and the Very Large Telescope in Chile (orange, red, and violet), and an optical image from astrophotographer Bob Fera (deep blue) combine to reveal R Aquarii. Nestled within the cozy ‘body’ of R Aquarii is a pair of stars where a white dwarf is pulling material from a much larger red giant companion. When enough material accumulates on the surface of the white dwarf, it triggers an outburst that sends a jet out into space. Over time, these jets twist and loop around each other weaving the structure seen today.

Frattare A cornucopia is a horn-shaped basket that traditionally carries fruits and vegetables. There is nothing edible in this pair of galactic cornucopias but there are a bounty of stars, dust, and other ingredients than make up these two spiral galaxies, known as NGC 2207 (right) and IC 2163 (left), that we see face-on. This view of NGC 2207 and IC 2163 takes a James Webb infrared image (white, gray, and red) and adds the X-ray view from Chandra (blue). Together, it is quite an eye-catching result.

The night sky is not the only marvel of the Atacama Desert.

One example? The Licancabur volcano, one of the great gatekeepers of ALMA. 5920 m high, it‘s part of a chain of mountains that separate Chile and Bolivia 🌋

A night skyscape is shown over snowcapped mountains. On the left is the band of the Milky Way Galaxy, while on the right is a bright comet with two tails -- a white tail going up and trailing to the right and a longer blue tail going up and trailing off to the left. Please see the explanation for more detailed information.

1/ A telescope fist bump in the sky 🤜 🤛

Our Unit Telescopes combine their light with interferometry to obtain the level of detail of a huge 130 m virtual telescope. But this requires correcting the effects of Earth’s atmosphere. This is where the lasers come in. 

🔭 🧪
Four massive cylindrical like structures are visible on the bottom. Out of all of these metal structures, a laser is shooting up into the sky to a spot where all four lasers meet

I just love painting bird of prey. Their power, intensity and sleek beauty are too hard to resist. Here are some watercolor paintings of a few species I made, the goshawk, the gyrfalcon and the peregrine falcon.

A Fuego sunrise. #photography
A sunrise view of Guatemala's Fuego volcano, shot from camp at 12,000 ft atop Acatenango. Fuego is seen erupting, with an ash cloud being emitted from the summit. Being well above the clouds, there are vibrant blue skies overhead and the cloud/haze layer is seen below.

Tension rises between the neighboring erectus family and a court of Gigantopithecus. Two weeks ago the cunning fleet-footed hunters managed to kill one of the young ponginae. This particularly huge dominant male won’t let it happen again. Illustration for Ben G Thomas.

The first of a paleoart series I'm calling "Perspectives," which aims to highlight the evolution of life on Earth with a variety of different creatures and styles.

This one is "Pale First Dot," depicting good ol' LUCA, the last universal common ancestor.
