	In the photograph, we see optical technician Claudio Araya testing the laser on the telescope responsible for propagating the laser, which is located above the secondary mirror of the Gemini South telescope in Chile, several meters above the observation floor. This small telescope projects the laser about 80 kilometers high, where the beam excites sodium particles present in the atmosphere, creating a constellation of five artificial guide stars. These false stars are detected on Earth by a wavefront sensor that calculates the distortion of their light and sends that information to a set of deformable mirrors. These mirrors, located on the optical bench, adjust in real time to correct these distortions and generate a well-defined image of the false stars. And when those five stars appear well-defined—as if a hole had opened in that portion of the atmosphere—it's time to aim at the real ones. Manuelivanparedes

	During the early mornings of June 10 and 11, 2025, a rare astronomical event took place: the Supertropical Full Moon set at its southernmost latitude just as the Sun appeared at its northernmost point on the horizon. This crossing of celestial extremes occurs only once every 18.6 years, as part of the major winter lunar standstill. The term Supertropical refers to a full Moon that rises and sets farther south than the Tropic of Capricorn, due to the tilt of the Moon’s orbit. The convergence of these solar and lunar extremes created a unique scene: the Moon descending in the southern sky while the Sun rose in the opposite direction. Beyond its visual impact, this event was tied to the Metonic Cycle, a 19-year period in which lunar phases return to the same dates in the solar calendar. The synchronization of both celestial bodies once again highlighted the elegance and precision of the cycles that govern our sky. Kinosmosis

Milky Way over Glaciar Juncal norte, Chile. Astrophotography taken from the viewpoint at the beginning of the glacier at midnight. At -10°C, this 5-photo panorama captures our galaxy's majesty above a frozen glacier and lagoon in Los Andes. A testament to planning and perseverance, fusing dark sky with the untamed beauty of a Chilean landscape. Angellogonz	By achieving a good composition with guiding lines thanks to the planting, a centered subject with the tree, and a Galactic Center with more detail and color than I've ever taken before, I achieved this incredible photograph. Taken from 9 Raw photos for the sky and 3 Raw photos for the ground, both at 30s f/3.5 and ISO-1600 with a Nikon D3300 and Nikkor 18-55mm lens. Tomás Andonie	Also called the “War and Peace Nebula,” it lies about 5,900 light‑years away, near the tail of the constellation Scorpius. This is a hydrogen‑alpha emission nebula (red in color) that can be seen for longer hours during Southern‑Hemisphere winter, appearing in the northeastern sky as soon as darkness falls and drifting toward the southwest through the night. At its center—the “lobster’s head,” the brightest region—sits the Pismis 24 open cluster, which hosts at least 20 stars, each roughly ten times larger than our Sun.

Located approximately 6,000 light-years away in the constellation Sagittarius, in a region of ionized hydrogen, lies a central structure known as the Hourglass Nebula. This area contains “young” nebulosity with stars that have formed just a few thousand years ago. It includes a region that emits its own light (red), where stars are born — the famous star nurseries. Photographed in Ha+OIII palette. . The first time I captured this object was from El Tránsito, Atacama Region, during a 5-hour session in March, under Bortle 2 skies and without filters. I later discovered that the “hand” extending from the Lagoon wasn't visible in my framing, which motivated me to revisit this target. I attempted to recover the data I acquired in Atacama and blend it with the images taken in the Biobío Region. . Data: 345 total images 26 exposures of 600 seconds under Bortle 4 skies (Cerro Alto, Hualqui) 319 exposures of 300 seconds under Bortle 7 skies (Talcahuano) Total integration time: 30 hours 55 minutes 7 acquisition nights between May 9 and May 30, with varied moon phases, from Full Moon to New Moon Telescope: WO Zenithstar 73, 430mm f/5.6 Guide scope: WO Uniguide 50mm Mount: SkyWatcher EQ6-R Pro Camera: Nikon Z6II Guide camera: Touptek Processing: PixInsight, Lightroom E.arayage96	Eta Carinae Nebula thorough Santiago City telescope Simiestroi	Photograph of the Great Orion Nebula and an attempt to reveal the interstellar dust surrounding it.

	The Villarrica Volcano in Pucón gave me a wonderful nighttime spectacle. A lenticular cloud illuminated by volcanic incandescence reminds me of the imposing power of this giant. Remember to exercise caution and respect, as this is the most active volcano in Chile and has the longest historical record of eruptions in South America. Rolyvidaura

These captivating images, taken on September 28, 2023, unveil a rare phenomenon atop the Andean mountain, Nevado de Juncal, standing at 5795 meters. This intriguing crossover reveals a unique synchronization of the Sun and the Moon rising over the same mountain peak, occurring every 19 years, precisely a week after the Spring Equinox. This alignment coincides with the emergence of the Spring Full Moon in the southern hemisphere, allowing both celestial bodies to grace opposite horizons, casting an intense amber glow upon the snow-clad mountain during moonrise. This cyclical event holds profound significance for archaeoastronomy, shedding light on the Incan worldview and the strategic observation infrastructure. The Andean mountains serve as exceptional guides, aiding in the determination of Lunar and Solar Standstills. The mesmerizing display epitomizes celestial harmony, governed by the Metonic Cycle, complementing the Saros Cycle's predictions of solar eclipses every 18.6 years. Additionally, the elliptical coincidence aligns with the lunar nodal precession, defining the time for the ascending node's 360° rotation relative to the vernal equinox. This influences the duration of a draconic month, shorter than the sidereal month. After one nodal precession period, draconic months exceed sidereal months by exactly one. This period spans about 6,793 days or 18.6 years. Beyond its archaeological significance, the novelty of this spectacle lies in the precise alignment of the Spring Full Moon and the Sun atop the same mountain peak. Capturing this precise alignment is unprecedented. This rare event, documented without relocating the camera tripod from its position at Las Antenas de Caleu in central Chile, signifies an astro-landscape synchrony that will not grace this location until the year 2460, spanning 23 Metonic Cycles" Kinosmosis	With different exposures, the solar corona was visible in one shot, and the chromosphere in the other.
