NASA APOD 25/06/28 - Lunar Farside

far side of the moon

Explanation: Tidally locked in synchronous rotation, the Moon always presents its familiar nearside to denizens of planet Earth. From lunar orbit, the Moon's farside can become familiar, though. In fact this sharp picture, a mosaic from the Lunar Reconnaissance Orbiter's wide angle camera, is centered on the lunar farside. Part of a global mosaic of over 15,000 images acquired between November 2009 and February 2011, the highest resolution version shows features at a scale of 100 meters per pixel. Surprisingly, the rough and battered surface of the farside looks very different from the nearside covered with smooth dark lunar maria. A likely explanation is that the farside crust is thicker, making it harder for molten material from the interior to flow to the surface and form dark, smooth maria.

galaxy

Explanation: Big beautiful barred spiral galaxy Messier 109 is the 109th entry in Charles Messier's famous catalog of bright Nebulae and Star Clusters. You can find it just below the Big Dipper's bowl in the northern constellation Ursa Major. In fact, bright dipper star Phecda, Gamma Ursa Majoris, produces the glare at the upper right corner of this telescopic frame. M109's prominent central bar gives the galaxy the appearance of the Greek letter "theta", θ, a common mathematical symbol representing an angle. M109 spans a very small angle in planet Earth's sky though, about 7 arcminutes or 0.12 degrees. But that small angle corresponds to an enormous 120,000 light-year diameter at the galaxy's estimated 60 million light-year distance. The brightest member of the now recognized Ursa Major galaxy cluster, M109 (aka NGC 3992) is joined by spiky foreground stars. Three small, fuzzy bluish galaxies also on the scene, identified (top to bottom) as UGC 6969, UGC 6940 and UGC 6923, are possibly satellite galaxies of the larger barred spiral galaxy Messier 109.

Wyoming’s Grand Tetons and Jackson Lake

Photographer: Ray Boren
Summary Author: Ray Boren

Under a big blue sky, the morning sun illuminates a central portion of Wyoming’s majestic Teton Range, which is mirrored via specular reflection in a calm and equally blue bay of Jackson Lake in Grand Teton National Park. In this photograph, taken on May 23, 2025, the park’s namesake Grand Teton peak, topping out at 13,775 feet (4,199 meters) above sea level, is on the far-left side of the image, to the south. Blocky Mount Moran (12,610 feet; 3,840 m) rises prominently just left of center. 

The snow still covering the Tetons on this spring day makes it easy to envision the Pleistocene ice-age glaciers that helped carve the mountains’ jagged summits, cirques, and U-shaped drainages. The Park Service explains that the Teton Fault began tilting the range’s primarily granite mountain block upward about 10 million years ago while also dropping the valley of Jackson Hole. Although masked by snow in the photograph, almost a dozen glaciers remain in the park today, some moving and some mere remnants. They, and erosion from water, wind and gravity, continue to shape the dramatic terrain.

small building with a tower beside it, stars are visible
same as the other but with multiple space objects labeled


Photographer: Rui Santos
Summary Author: Rui Santos

The night sky and planetary alignment featured above was captured from Pinhal de Leiria, Portugal on February 28, 2025. I decided to view the alignment from here because I knew I'd have a clear view of the horizon. Since the planets were stretched out across the sky, I had to do a panorama and try to avoid light pollution (lower left and lower right) from surrounding cities and towns. Venus, Jupiter, Mars and Uranus are included above, but because I wasn't able to arrive as the Sun was setting, Saturn, Neptune and Mercury aren't in the frame.

At bottom center is the Crastinha Lookout Point, one of several watchtowers in the Forest of Leiria. The building to its right is the reconstruction of what used to be the guard's house, dating from 1883. This tower is still in use today.

Photo Details: Panorama of 4 panels x 10 photos on each panel; Sony A6000 camera; Samyang 12mm F2; 40 x 20 seconds exposure; 6400 ISO; F2.8; 8:16 pm local time. Tripod: Geekoto AT24Pro Dreamer + Andoer Q08S Rotating Head. Processing: PTGUI, Lightroom, Photoshop, RCplugins, Luminar.

closeup of a crystal

Kunzite is the pink to light purple gem variety of the mineral Spodumene. Spodumene is a common mineral, but only in several localities does it occur in transparent gem form. The main gem form of Spodumene is Kunzite, the other is the rarer Hiddenite. Yellow and colorless gem forms of Spodumene also exist, but are not commonly faceted as gemstones. Kunzite has a lovely pink color and is becoming increasingly popular in the gemstone market.

Chemical Formula: LiAlSi2O6
Color: Pink, Purple
Hardness: 6.5 - 7
Crystal System: Monoclinic
Refractive Index: 1.66 - 1.68
SG: 3.1 - 3.2
Transparency: Transparent
Double Refraction: .015
Luster: Vitreous
Cleavage: 1,2 - prismatic
Mineral Class: Spodumene

All About:
Kunzite is a relatively recent gemstone, having been first discovered in the 20th century. It was first found in the pegmatites of Pala, California, in 1902, and is named after the famous mineralogist George F. Kunz who first identified it. Though it wasn't until the 1990's that this gemstone became a more mainstream gemstone, having been used only as a collectors gemstone prior to that time.

Kunzite is a very attractive pink gem, but is notorious for its habit of color fading in prolonged exposure to strong light. Although the color-fading effect is very slow, most people still prefer to wear Kunzite jewelery in the evening to avoid sunlight exposure. Kunzite is regarded as an evening stone for this reason.

Kunzite deposits are quite extensive and yield large amounts of this gemstone, thus making it very affordable. Extremely large and flawless crystals of Kunzite have been found, and these can yield very large and flawless faceted gemstones.

The perfect cleavage and splintery fracture of Kunzite makes it a difficult gemstone to facet. It is very sensitive to knocks and will chip if hit too hard. Kunzite is known for its strong pleochroism, showing lighter and more intense coloring when viewed at different angles. For this reason, it is always cut to show the deepest pink color through the top of the gem. The deeper pink the Kunzite, the more valuable it generally is.


Uses:
Although Kunzite is a relatively soft and delicate gem, and can fade after prolonged exposure to light, its appealing color makes it a popular gem. Small gems are not commonly cut from Kunzite because of its cleavage and strong pleochroism. It is most often used as a pendant stone and as a large decorating stone on ornamental objects. It is less commonly used in rings, necklaces, or other jewelry items where small stones are required. Less transparent stones are sometimes cut into cabochons and beads.

Varieties:
Blue Kunzite - Light blue to bluish green transparent form of Spodumene.
Yellow Kunzite - Yellow transparent form of Spodumene.



History and Introduction:
Kunzite is the pale pink to light-violet gem-quality variety of the pyroxene mineral spodumene, a lithium aluminum inosilicate. Kunzite was first discovered in Connecticut, USA, and was named after George Frederick Kunz (1856 - 1932), an American mineralogist and the former vice president and buyer for Tiffany & Company. Kunz was a legendary New York jeweler and colored stone specialist, and he was the first to comprehensively describe the stone in 1902.

Although it was first discovered in the USA, most of the current supply of kunzite is found in Afghanistan and Pakistan. Kunzite is closely related to hiddenite, the yellow-green member of the spodumene gemstone family which was also discovered and named after an American mineralogist, W. E. Hidden; as well as the classic golden to yellow color gem-quality spodumene. Kunzite is known to produce gemstones of great size. In fact, it's not uncommon to find fine quality stones weighing 20 carats or more. Kunzite and the entire spodumene group are important industrial sources of lithium, which is used for the making of medicines, ceramics, mobile phones and automotive batteries.

TFW in the course of an archaeological dig on LiveJournal you seem to have found yourself, except Norwegian, and wonder whyyyy you never crossed paths back in the day. Other than that I am not into The Mighty Boosh and not really into Red Dwarf slash (just the show in general)... bah! just look at that fannish interests list! even "purple hair" and about my same age!

([personal profile] kahvi here is an RP journal and not the same person. Well, I assume not the same person.)

eta: [archiveofourown.org profile] kahvi seems to be the same person, though, judging by the list of fandoms their works belong to, and is even likely to be still active (last posted December 2024).

I was going through old LiveJournal memories links, as I'm thinking of finally deleting one of my LJ accounts... I had a whole category for posts in the community [livejournal.com profile] glamourbombs. This is just a selection. (Some, I was kinda "meh" on reading them just now; and a couple were like... yeah, in 2005 you maybe could have done that without getting shot, but you'd be taking your life in your hands, now.) Some are more about general philosophy/technique than specific prompt ideas.
