As long as Earth has spun on its axis in orbit around the sun, the planet has known night. Each day, half the world slips into shadow, creating the natural rhythm of light and dark under which life on Earth has evolved.

Each day, half the world slips into shadow, creating the natural rhythm of light and dark under which life on Earth has evolved.

Now, a private California-based startup is proposing a different future, one in which thousands of in-space mirrors mounted on satellites direct light down to targeted areas on Earth, threatening natural darkness. The company describes this concept as “sunlight on demand,” an idea that would fundamentally alter the nighttime environment as we know it.

A look back at our very busy and successful year.

It is very gratifying that our TIVOLI location has a worldwide reputation as an excellent site for remote observatories. Last year alone, five new remote observatories of varying sizes were established, for both companies and private individuals. As part of this development, a self-catering unit was created to meet the needs of remote observatory owners. Our TIVOLI guesthouse continues to be very popular, making it necessary to create flexible accommodation. We can now offer four self-catering rooms on short notice. You will soon find all the details about this addition on our website: tivoli-astrofarm.de.

To all our loyal customers, friends, and family, we wish you a peaceful holiday season, a Merry Christmas, and a Happy New Year 2026!

Astrophotographers capture interstellar comet in Namibia as NASA confirms ancient, natural origin

ASTROPHOTOGRAPHERS Gerald Rhemann and Michael Jäger have recently captured a striking image of interstellar comet 3I/ATLAS from Namibia — a rare visitor that NASA now confirms is both ancient and entirely natural in origin. New findings from an unprecedented multi-mission observation campaign reveal the comet’s unusual chemistry, its long journey through interstellar space, and its origins in a planetary system far older than our own.

NASA announced that 3I/ATLAS — only the third confirmed object to enter our solar system from beyond it — shows no signs of artificial or technological origins, dispelling viral speculation. Instead, the comet behaves like a classic icy body, with data from more than 20 spacecraft and ground-based observatories offering the most comprehensive scientific profile of any interstellar comet to date.

Missions including the Mars Reconnaissance Orbiter, MAVEN, Lucy, SOHO, and Psyche tracked the comet from multiple vantage points across the solar system. This network allowed researchers to monitor its dust, gas, and coma structure even when Earth-based telescopes could no longer see it. MAVEN detected hydrogen from vaporising water, Lucy helped reconstruct the comet’s dust tail in three dimensions, and SOHO recorded an unexpected bright pass in its field of view.

Further analysis from the Hubble Space Telescope and the James Webb Space Telescope revealed that 3I/ATLAS contains unusually high carbon dioxide relative to water, as well as distinct dust grain characteristics not observed in local solar-system comets. These chemical signatures indicate that the object formed in a radiation-rich environment around a star system that predates our own.

Scientists say the comet’s velocity and trajectory confirm an interstellar origin and pose no risk to Earth; it will pass at a safe distance of roughly 273.6 million kilometres (170 million miles).

NASA said that the combined dataset not only confirms the comet’s natural makeup but also offers a rare look into the early building blocks of ancient planetary systems elsewhere in the galaxy.
