Ante todo, tranquilidad: de aquí a finales de julio pueden salir dos o tres partidos de izquierdas más. Tiempo hay. No se me atolondren.

AAVSO finder chart for the field of #supernova #2023ixf in #M101, plotted with a 1º field of view and a limiting magnitude of 14. Comparison star magnitudes are shown without decimal points, so, e.g., "119" = magnitude +11.9.

Welcome to this month's look at #Starlink conjunction risk mitigation manoeuvres. Through 30 April 2023, I estimate that Starlink satellites have made a total of > 45,000 manoeuvres to mitigate the risk of colliding with other space objects. The number of manoeuvres is growing exponentially (see later in the thread) because the number of Starlink satellites in orbit is increasing and the number of other objects in orbit is increasing [1/n]

For my chemistry friends out there - today's #t-shirt.

This morning I presented our concept for a future nighttime lights satellite called #EULE as a candidate for the European Space Agency's "Earth Explorer 12" call.

Hoy @pampa habla de que las gentes de ciencia son personas, aunque se las suela endiosar... "No son seres de luz, solo hacen ciencia". Cuánta razón llevas, Pampa, el periodismo científico es necesariamente crítico, especialmente cuando hay materia para ello (guiño guiño)

En #Alemania han sacado un abono de transporte mensual por 49€ que puedes usar en trenes, metros, autobuses...De todo el país.
Han vendido 3 millones de abonos.
Con esto sí acabas con el coche particular, no subvencionando coches eléctricos a gente que puede pagar 50.000 por un #Tesla.

Para sorpresa de nadie:

"The model produces a simple expression for the maximum quantity of #satellites to prevent the #KesslerSyndrome, depending on a combination of parameters. Given the baseline calibration of the model, the estimated aggregate threshold value for the quantity of satellites is about 72,000."

Still remember this time I was looking out the window at the place I worked and was watching someone use a traffic cone to try and scrape the ice off their windshield.

My coworker just mumbled "that's not how you install VLC on windows" to himself as he walked by looking and nobody will ever tell a better joke than that.
