The subject of this image is a group of three galaxies, collectively known as NGC 7764A. They were imaged by the NASA/ESA Hubble Space Telescope, using both its Advanced Camera for Surveys (ACS) and Wide Field Camera 3 (WFC3). The two galaxies in the upper right of the image appear to be interacting with one another — indeed, the long trails of stars and gas extending from them both give the impression that they have both just been struck at great speed, thrown into disarray by the bowling-ball-shaped galaxy to the lower left of the image. In reality, however, interactions between galaxies happen over very long time periods, and galaxies rarely collide head-on with one another. It is also unclear whether the galaxy to the lower left is actually interacting with the other two, although they are so relatively close in space that it seems possible that they are. By happy coincidence, the collective interaction between these galaxies have caused the two on the upper right to form a shape, which from our Solar System's perspective, ressembles the starship known as the USS Enterprise from Star Trek!
NGC 7764A, which lies about 425 million light years from Earth in the constellation Phoenix, is a fascinating example of just how awkward astronomical nomenclature can be. The three galaxies are individually referred to as NGC 7764A1, NGC 7764A2 and NGC 7764A3, and just to be really difficult, an entirely separate galaxy, named NGC 7764, sits in the skies about a Moon’s distance (as seen from Earth) away. This rather haphazard naming makes more sense when we consider that many of the catalogues for keeping track of celestial bodies were compiled well over 100 years ago, long before modern technology made standardising scientific terminology much easier. As it is, many astronomical objects have several different names, or might have names that are so similar to other objects’ names that they cause confusion.

This is a shot from my descent down from the Matterhorn. From this high up, it truly is a birds eye view of the valley below. Again, it's another shot from a week or two ago. I'm back in California now.

Commonly known as bank catclaw, prostrate acacia, or desert carpet, it is a shrub introduced to Southern California from SW Australia. It is considered an invasive species in parts of California.
The star nicknamed Earendel (indicated here with an arrow) is positioned along a ripple in spacetime that gives it extreme magnification, allowing it to emerge into view from its host galaxy, which appears as a red smear across the sky. The whole scene is viewed through the distorted lens created by a massive galaxy cluster in the intervening space, which allows the galaxy's features to be seen, but also warps their appearance—an effect astronomers call gravitational lensing. The red dots on either side of Earendel are one star cluster that is mirrored on either side of the ripple, a result of the gravitational lensing distortion. The entire galaxy, called the Sunrise Arc, appears three times, and knots along its length are more mirrored star clusters. Earendel's unique position right along the line of most extreme magnification allows it to be detected, even though it is not a cluster.
With this observation, the NASA/ESA Hubble Space Telescope has established an extraordinary new benchmark: detecting the light of a star that existed within the first billion years after the Universe’s birth in the Big Bang (at a redshift of 6.2) — the most distant individual star ever seen. This sets up a major target for the NASA/ESA/CSA James Webb Space Telescope in its first year.

This was our neighbor's house, he lived here when I was growing up. Of course he's passed on now, and the house is abandoned. So many of the places that were once occupied are now empty, either repurposed as farm buildings or slowly decaying.
Another shot of the Lake Berryessa Glory Hole. My timing sucked, with the hole-side of the valley in shadow.
Other pic here, which gives a better sense of scale. Link. The drop is over 200 feet, over 60 meters straight down, the diameter is 72 feet or about 22 meters. Somebody has of course fallen in, and needless to say, perished.
Lake Berryessa is artificial, a flooded valley. Somewhere deep under there was once the town of Monticello. As well as forcibly moving the residents, they also moved a cemetery, which was relocated to the banks for the lake.

For Asteroid Day, the Copernicus Sentinel-2 mission takes us over the Shoemaker Impact Structure (formerly known as Teague Ring) in Western Australia.
Located around 100 km northeast of the small town Wiluna, the Shoemaker Impact Structure was renamed in honour of Eugene Shoemaker, a planetary geologist and pioneer in impact crater studies.
The almost circular shape of the Shoemaker impact site, visible in the bottom-right of the image, is approximately 30 km in diameter and is defined by concentric rings formed in sedimentary rocks (seen in dark brown). The precise age of the impact is unknown, but is estimated to be between 1000 and 600 million years ago – making it Australia’s oldest impact crater.
This false-colour image was processed by selecting spectral bands that can be used for classifying geological features, allowing us to clearly identify the concentric rings in the image. The light blue areas are saline and ephemeral lakes including Nabberu, Teague, Shoemaker and other smaller ponds.
Asteroid Day, the UN-endorsed global awareness campaign is back on 30 June with an exciting 5-hour live broadcast from 18:00 CET. With the help of leading experts, Asteroid Day Co-founder Dr. Brian May and the most engaging voices in science communications from around the world, the five hour programme will bring the solar system’s smallest worlds to vivid life for audiences of all ages and backgrounds. For more information, visit ESA joins Asteroid Day for rocky live broadcast.

La terre est bleue comme une orange...
La terre est bleue comme une orange
Jamais une erreur les mots ne mentent pas
Ils ne vous donnent plus à chanter
Au tour des baisers de s’entendre
Les fous et les amours
Elle sa bouche d’alliance
Tous les secrets tous les sourires
Et quels vêtements d’indulgence
À la croire toute nue.
Les guêpes fleurissent vert
L’aube se passe autour du cou
Un collier de fenêtres
Des ailes couvrent les feuilles
Tu as toutes les joies solaires
Tout le soleil sur la terre
Sur les chemins de ta beauté.
[Paul ELUARD] - L'Amour la poésie - (1929)

This NASA/ESA Hubble Space Telescope image of the asteroid Dimorphos was taken on 19 December 2022, nearly four months after the asteroid was impacted by NASA’s DART (Double Asteroid Redirection Test) mission. Hubble’s sensitivity reveals a few dozen boulders knocked off the asteroid by the force of the collision. These are among the faintest objects Hubble has ever photographed inside the Solar System. The ejected boulders range in size from 1 m to 6.7 m across, based on Hubble photometry. They are drifting away from the asteroid at around 1 km per hour. The discovery yields invaluable insights into the behaviour of a small asteroid when it is hit by a projectile for the purpose of altering its trajectory.
[Image Description: The bright white object at lower left is the asteroid Dimorphos. It has a blue dust tail extending diagonally to the upper right. A cluster of blue dots surrounds the asteroid. These are boulders that were knocked off the asteroid when, on 26 September 2022, NASA deliberately slammed the half-tonne DART impactor spacecraft into the asteroid as a test of what it would take to deflect some future asteroid from hitting Earth. Hubble photographed the slow-moving boulders in December 2022.]

A quick drive down to the Grand Canyon (3 days) before returning to work tomorrow. Spectacular as always, with lots of snow on the rim, and a dusting on the walls.
These charming birds are not only known for their love of fruit, but they also have a unique social behavior during mating. During courtship, Cedar Waxwings perform a special dance and exchange small gifts like flower petals or insects. If the female is interested, she’ll dance back, and they may even rub their beaks together affectionately.
Toyon is rich in flavonoids and phenolic compounds, which have antioxidant effects. These compounds help combat oxidative stress and may protect cells from damage.
The species is from the southern hemisphere and was first discovered in Britain in 1914. The devil’s fingers fungus hatches from a slimy, gelatinous ‘egg’. As it grows, the tentacle-like arms start to protrude. The bright red colour of this fungus makes it easy to spot. Related to the stinkhorns it has a strong and unpleasant smell.
A Western Bluebird dropped by yesterday afternoon. Although they're around, I think this is the first time, I've ever had one at my house.
Zermatt, it's a pleasant town, but seriously they need to sort out all the traffic!!! This was base camp to getting up closer to the Matterhorn. I warned you all that I would be posting more gratuitous Matterhorn images!!! This is from a couple of weeks ago in Switzerland.
The whole traffic thing is a joke of course. Zermatt is actually combustion engine free, only electric and "grass-powered" vehicles up here. Which means you can't actually drive here, you need to take the spectacular cogwheel train to get to the village. Steep sections of the railway have cogs to stop the train from slipping backward or going down too quickly.
The horseman's outfit matches the Valais flag, which is the canton that Zermatt is in.
I am a bit short of current fly pictures these days ...must try to correct that this weekend.
Happy FlyDay Friday!
... because chives blossoms are very special - they taste juicy, sweet flavor of chives with a little nectar. Simply delicious!

Not original. This is a extreme closeup of a painting in the lobby of a building somewhere in the Chicago loop.
This is the vibrant liquid light from the stained glass windows of the Sagrada Familia. The color comes from 100% filtered sunlight. Astonishing genius from Gaudi, the light changed continuously while I was there.

A big harvest this year, this group of woodpeckers have been harvesting for over 6 weeks, and have created two new granaries to store their acorns, this one on the roofs of several houses, and another on a palm tree. Normally they just use an old oak tree. It's so crazy now that they have to hop from tile to tile trying to find room for just one more acorn.
Loved this redhead's shadow too, with its big acorn revealed, and how clearly you can see how they use their tails to steady themselves.
Fascinating, innovative, super social creatures.
