#TIL that fortunately someone has already invented a term that was on my mind but for which no word seemed to already exist.

Thank you, Urban Dictionary: https://www.urbandictionary.com/define.php?term=Spacewashing

A estas alturas ya sabemos todos que lo de que nos fumigan es falso. Pero, ¿Sabéis cuál es el origen del bulo?

Así hemos contado en Canal Sur el bólido impresionante que se ha visto esta pasada madrugada en España y Portugal. Gracias, @jmmadiedo

Six months after it suffered a serious brain injury and after months of mind-boggling ultra-long-distance surgery, the Voyager 1 spacecraft walked and talked at full data rate today!

After a full memory readout today at 40 bps, Voyager 1 switched to the science-mode 160 bps rate, which the DSN site at Goldstone was able to receive and decode.

Congrats and kudos to all who made it happen.

Bumper sticker: “Creationists shouldn’t be allowed to use fossil fuels.”

Sounds fair

In early 2023, a new comet took stargazers by surprise. Called Comet C/2023 A3 (Tsuchinan-Atlas), this icy visitor was discovered by two separate observatories in South Africa and China. Comet A3 had scientists and amateurs alike wondering if it would be the next naked-eye comet to light our skies. As 2024 unfolds, we eagerly anticipate whether Comet A3 will deliver the breathtaking celestial display we have all been hoping for!

Ouch.

If you were in orbit around Saturn today, you would see Mars transit across the Sun! From Saturn's orbit, the Sun is only 10% of its size as seen from Earth, and Mars would be only ~1/200th of _that_. You would need good equipment to see this transit...

Artificial light is good and beneficial to humanity. But it's also possible to have too much of a good thing.

Bad news for radio astronomy AND optical astronomy. Not only is 'Supplemental Coverage from Space' (aka direct-to-cell) transmission unregulated at this point, but the 2nd generation of #BlueBird satellites will be monstrously large reflectors of sunlight.

So, over in the astronomy world there is some considerable consternation about a tweet from eminent satellite tracker Jonathan McDowell.

Apparently "Starlink Precipitation" is now a thing. And yes, you got that right, Starlink precipitation is pieces of Elon Musk's fucking internet satellites raining down from space.

¡Una noche inolvidable!
Como todos sabemos, la noche del 10 y madrugada del 11 de mayo, la aurora llegó a ser visible desde latitudes tan bajas como las de las Islas Canarias. El punto desde donde la captamos, no llegaba aún a 28°N.

Jajajajaja https://www.elmundotoday.com/2024/05/hipocresia-un-video-muestra-a-greta-thunberg-respirando-oxigeno/

@KathyReid theres a meme for that

Em fa ràbia que tanta gent a #Olot vulgui fer fora companys de feina i mares de l'Escola Bressol de la meva filla, per no haver nascut aquí.
Son els nostres amics i ara són catalanes com vosaltres.

A #Olot el que sobre són #racistes #classistes

Hi posarem el cos, l'ànima i tota l'energia per combatre la vostra xenofòbia.

As usual XKCD hits the nail on the head.

Incoming! A severe G4 Geomagnetic Storm is expected to arrive around 02:00 UTC Friday night / Saturday morning.

At least 5 Coronal Mass Ejections took place over the past 24 hours, directed towards Earth. These originated from a large and magnetically complex sunspot cluster (NOAA region 3664).

There is potential for disruption of communications, the electric power grid, navigation, radio and satellite operations.

And bright auroras as far south as Alabama!
