Kommende Nacht um 03:12 MEZ ist Vollmond. #astronomie #astrodon

This evening I learned the following bizarre things:
0/ Colliding massive objects create gravity waves (this I already knew).
1/ When spinning black holes collide, they experience an acceleration at right angles to the sum of the spins.
2/ The bigger the black holes, the greater the acceleration and resulting speed.
3/ When this happens with galactic core supermassive black holes, this can exceed the escape velocity of the galaxies.
4/ When one of these high-speed supermassive black holes encounters a dust or gas cloud, it creates a contrail of stars! And we can see these star-contrails - straight lines of stars, scattered across the cosmos!

Thank-you Professor David Blair!

Hubble Sees Possible Runaway Black Hole Creating a Trail of Stars

There's an invisible monster on the loose, barreling through intergalactic space so fast that if it were in our solar system, it could travel from Earth to

Heute Nacht um 00:24 Uhr (MESZ) sollen mit Artemis II nach 54 Jahren wieder Menschen Richtung Mond fliegen. Unser Autor Christoph Otto hat mit dem Piloten gesprochen, dem NASA-Astronauten Victor Glover:

Und er hat auch tolle Fotos in den Trainingshallen geschossen!

Artemis II startet: Victor Glover fliegt zum Mond, Interview mit dem NASA Piloten von Christoph …

Der US-Amerikaner ist einer von vier Raumfahrern, die die NASA nach 54 Jahren Pause wieder Richtung Mond schickt. Die Mission Artemis II gilt als Vorbereitung für spätere Landungen auf dem Mond und dem Mars. Der NASA-Astronaut ist Pilot des neuen Raumschiffs Orion. .

"Given that the predictive power of science fiction is well established, we suggest that these locations might be prioritised by searches for extrasolar biospheres."

What an excellent paper by Elizabeth R Stanway from Warwick, never thoughts I'd see such an amazing collaboration between astronomy and digital humanities!

Where to Search For Life: Evidence from narrative sources with established predictive efficacy

The search for habitable planets, and even for ``Earth 2.0'', is a major driver in contemporary astronomy. However selecting target fields to prioritise for such searches presents a challenge. Here we establish a statistical analysis of the appearance of constellation names in science fiction magazines of the pulp era, evaluating the most commonly mentioned constellations and thus those which the science fiction community collectively identify as the most likely locations to find life. Given that the predictive power of science fiction is well established, we suggest that these locations might be prioritised by searches for extrasolar biospheres.

Tomorrow morning, Australia will play a vital role in supporting #ArtemisII through the @canberradsn - the CDSCC (and as part of Australia's national science agency, CSIRO)

I spoke with folks at CDSCC, along with Associated Prof. Alice Gorman (Dr Space Junk), folks at NASA and more about this historical mission.

The CDSCC is not the only Aussie team that is working with the Artemis II mission - researchers from the Australian National University are also testing emerging technology that allows data to be transmitted via lasers, instead of radio waves at Mount Stromlo.

Importantly, Artemis II is going to set some new records that have not been attempted for 54 years.

And for the first time, the first woman, the first person of colour and the first non-American will travel to lunar space.

Godspeed, humans! Ad Astra!

Another shot from the early pre-dawn of March 16th. I was trying to capture the Milky Way core but it clouded up. The clouds were all moving the same direction and it made a neat streaking effect over ~5 minutes of exposure. The purple light is real (I was playing around with ambient lighting during the shot).

16mm f/1.8 lens on Nikon Z6 ii, captured in 13" subs.
