Saturn: One week after opposition

My first image of Saturn this year. Saturn's opposition was last week on October 4th, so we are one week further. Seeing was moderate and transparancy fair. 

300 Days to go for Total Solar Eclipse Aug 2, 2027

The next total solar eclipse will happen in 300 days.
If all goes according the plan, I will be @ Djerba in Tunisia. 

Software for Photometry

I'm preparing a lecture on Photometry and as part of this I completed a comparison between different software packages. Personaly I only have experience with ASTAP but with some upcoming and upgraded software the landscape is changing. The below tabel is made using AI.

Lecture on Infinity by philosopher Victor Gijsbers

Attending a philosopher's lecture at Studium Generale @ Maastricht.

Humanity is caught between longing for eternity and the reality of our fragile, fleeting existence. In his acclaimed book "Oneindigheid: een filosofische gids", Leiden philosopher Victor Gijsbers explores if the universe is infinite and how we should live within it. He questions whether endless space holds copies of us and if immortality would truly improve our lives—or prove far more agonizing than our finite mortality. Gijsbers suggests endless time might strip our choices of consequence and become a psychological burden. 

Pushing this further, 19th-century thinker Louis-Auguste Blanqui argued in L'éternité par les astres that finite elements in an infinite cosmos mean every life, and every form of immortality, repeats itself identically across the stars. Does this infinite loop rob us of unique meaning, or does it give our finite moments ultimate weight? 

At the end of the lecture, reference was made to mathematics and infinitity and what this tells us about reality. 

True to tradition, I naturally had to snap a selfie at the lecture to document my own tiny, fleeting moment against this vast cosmic backdrop! Some thinking...would I want to live forever, or does my mortality define my value?

My interview of Total Solar Eclipse published in Magazine Zenit of October 2026

 

For any eclipse chaser, seeing totality is a breathtaking experience, but having your observation featured in a renowned astronomy publication makes it all the more special. In the October edition of the well-known Dutch astronomy magazine Zenit, written by Mat Drummen, my interview about the Total Solar Eclipse of August 12, 2026, was officially published. The article captures the firsthand experiences of observers who traveled to Spain to witness this spectacular celestial event, and I was thrilled to share my own story alongside other passionate stargazers—including the famous Dutch science journalist Govert Schilling.

My vantage point for the eclipse was the tranquil municipality of Carrión de los Condes in the province of Palencia, Spain. To capture the event from a unique perspective, I piloted a drone to an altitude of 24 meters, recording beautiful aerial film footage as the Moon gradually blocked out the Sun. Because the eclipse occurred low on the horizon, the atmosphere during totality was truly idyllic, painting the Spanish sky with dramatic, warm tones. Just as totality began and the Sun’s corona burst into view, a wave of applause and cheers echoed from observers in the distance, capturing the shared awe of everyone gathered under the Moon's shadow. Being featured in Zenit is a wonderful reminder of an unforgettable trip, and it is an honor to have these memories preserved in print for the broader astronomy community.

Supernova SN 2026aaiv in NGC7331 - ASTAP

Supernova SN 2026aaiv is located in NGC7331. NGC7331 is a Herschel 400 object and located in constellation Pegasus. According Stephen James O'Meara's Herschel 400 Observing Guide (p 283), the spiral galaxy is mag 9,5 and a fairly easy object to observe. It's distance is 46 million ly (The complete guide to the Herschel Objects). 

I used ASTAP software to analyse the pictures. Format is fit and the best image out of 14 was selected using APP. After solving, analysing and selecting the Green channel, the DSO annotation and magnitude was completed.

The magnitude of the SN is 12,6 according ASTAP. For comparison, rochesterastronomy shows in the same green channel a value between 12,1 and 12,2 on september 20 and 22.

Carlo Rovelli and the Quantum Cosmos

Reimagining Space, Time, and Reality: Carlo Rovelli and the Quantum Cosmos

Italian theoretical physicist Carlo Rovelli (1956) is one of the most compelling voices in modern physics, bridging general relativity and quantum mechanics through Loop Quantum Gravity (LQG). He introduces a fundamental shift in our understanding of nature: space is not a continuous, empty backdrop, but a granular network composed of discrete "atoms of space" at the Planck scale.

At this fundamental quantum level, physical time as a universal, flowing stream completely disappears. Instead, time emerges merely from thermal entropy and relational interactions between systems, challenging our deepest intuitions about cause and temporal progression in astrophysics.

His work on astrophysics and black hole thermodynamics explores the ultimate fate of collapsing stars. Rather than ending in infinite gravitational singularities where physics breaks down, quantum pressure causes black holes to reach a minimum threshold and rebound into short-lived, emitting "white holes"—a theoretical phenomenon offering key insights into early universe dynamics.

Finally, Rovelli unifies his mathematical physics with a profound philosophical framework. He argues that all cosmic phenomena—from subatomic particles to human thought and distant galaxies—exist on an equal, relational plane. Reality is not a static hierarchy of distinct objects, but an interconnected web of physical interactions shaping our quantum universe.

My Carlo Rovelli collection .... so far :)

Unbounded Universe: An Unforgettable Evening with Govert Schilling on the James Webb Space Telescope.

The James Webb Space Telescope is undeniably astronomy's newest darling. Launched in late 2021 as the successor to the iconic Hubble Space Telescope, this ultra-sensitive space observatory has been churning out fascinating results and spectacular deep-space photos almost continuously.

I recently had the pleasure of attending a lecture in Maastricht about this marvel of engineering, presented by renowned science journalist Govert Schilling. Titled Unbounded Universe: A Journey Through the Cosmos with the James Webb Space Telescope, the presentation took us through the rich history, complex construction, and ingenious design of JWST. Govert showcased a stunning array of impressive images, offering a breathtaking introduction to the mysterious cosmos we all call home.

I was joined by my Helios colleague Walter for the evening. The atmosphere was buzzing because the auditorium was completely packed to capacity, and there was even a waiting list to get in. It is always inspiring to see such a massive turnout of people eager to learn about the wonders of our universe.

At the end of the lecture, I managed to catch up with Govert and take a quick selfie to add to my collection from previous talks, keeping the tradition alive.

It was a fantastic evening filled with awe-inspiring science, incredible visual art from the depths of space, and great camaraderie. A huge thank you to Govert Schilling for another wonderful presentation!
