in memory of Nichi D’Amico

The Astronomers Appeal Staff dedicates a minute of meditation to the INAF president Nichi D’Amico, who passed away a few days ago. We hope that his successor will continue in the Italian Institue for Astrophysics in the wake of the fight against the satellites’ constellations, reaping the fruits of the work of prof. D’Amico, togetherContinue reading “in memory of Nichi D’Amico”

LET’S PLAY WITH PHOTOSHOP!

ENGLISH: Starting from Real Today’s Picture (with 420satellites) of Zdenek Bardon with a Nikon D810a and Optics ZEISS Otus 1,4/100 6x120secs, we predict how we will admire the night sky when 12k satellites will be displaed in LEO at 550Km altitude and how the same picture would be when other 30k satellites at 340Km (totalContinue reading “LET’S PLAY WITH PHOTOSHOP!”

PRESS RELEASE: APPEAL BY ASTRONOMERS confirms the commitment given to the 2000 signatory colleagues to bring to completition our inhibition action on satellites’ constellations!

Climate Changes and Satellites’ Constellations

Why are climate changes and “Global Warming” so important for our Environment and Biosphere? Do Satellites’ Constellations represent a threat to our Environment? Simple because it represents an physical effect that is called positive feedback, that is, a chain reaction that once triggered feeds itself and necessarily leads to the breaking of some sort ofContinue reading “Climate Changes and Satellites’ Constellations”

Satellites’ Constellations … news!

One good news in times of Coronavirus! OneWeb is going to Bankrupt!!! Waiting for bankrupt of SpaceX. In the meantime IAU stated that DARKSAT was not so dark… As we alteady stated two months ago! Even in quarantine SpaceX continue to launch in orbit Starlink satellites. Now the total amount of Starlink fleet is composedContinue reading “Satellites’ Constellations … news!”

Concerns about ground based astronomical observations: QUANTIFYING SATELLITES’ CONSTELLATIONS DAMAGES

In pubblications on arXiv the second preprint on SATELLITES’ CONSTELLATIONS DAMAGES. HERE you can download the .pdf HERE you can download the .pdf ABSTRACT: This article is a second analysis step from the descriptive arXiv:2001.10952 preprint. This work is aimed to arise awareness to the scientific astronomical community about the negative impact of satellites’ mega-constellationsContinue reading “Concerns about ground based astronomical observations: QUANTIFYING SATELLITES’ CONSTELLATIONS DAMAGES”

NEW Article from ESO on the impact of Satellites

https://www.eso.org/public/news/eso2004/?lang At this link it is possible to find an article “from ESO” on the impact of satellites (here the paper on arXiv -> https://www.eso.org/public/archives/releases/sciencepapers/eso2004/eso2004a.pdf ) Unfortunately we MUST comment that this work is completely underestimated since the TOTAL NUMBER of satellites taken into account is 26,750 (just half of the SpaceX/Starlink fleet!!!). So theContinue reading “NEW Article from ESO on the impact of Satellites”

new preprint is coming…

The following table is extracted by the next article work in progress (at 75%). The updated list of all satellites’ constellations is greater than ever: all simulations performed since the current day underestimate the total number of satellite. We must stop them before it is too late! Or we will need to adapt us toContinue reading “new preprint is coming…”
