Star colours are an extremely important aspect of #Indigenous #Astronomy. Luritja #Aboriginal people of Central #Australia developed a stellar classification system based on #star colour, primarily focusing on red and white stars.

#thefirstastronomers #astrophysics #science
A majority of stars you see in the sky appear white (F/A class, such as #Sirius & #Canopus).

Some appear blue (O/B-class, such as #Rigel), orange (K-class, such as #Arcturus), red (M-class, such as #Betelgeuse).

Red stars have special importance due to their relative rarity
Red stars often reflect the colour of their terrestrial counterpart in Indigenous Knowledge Systems as a memory marker.

One example is the red-tailed black #cockatoo, which is linked to the star #Antares and planet #Mars in Aboriginal traditions across the Great Victoria Desert.

#EpigraphyTuesday – The Foss Dyke Mars: a statuette of Mars, nude apart from his rather flamboyant helmet: found on the course of the Foss Dyke in 1774, though the original find-spot is not specified. #Roman #Mars

Image: British Museum (OA.248). Link - britishmuseum.org/collection/obj…
This ca. Late 2nd – Early 3rd Century copper-alloy figure is well executed, highlighting once again the popularity of Mars as a Romano-British cult focus, as shown in other artefacts such as the Barkway Plaque.

The inscription runs across two of the panels on the base:

Deo Mar(ti) et
Nu(mini)b(us) Aug(ustorum) Col-

#Saturn and #Venus is a natural pair. Saturn is the fixed expression of Libra as its middle decan, and also the mutable expression of Taurus as it's third decan, transforming into Gemini. Venus exalts Saturn in Libra, masculine cardinal air sign.
Furthermore, Venus is the cardinal expression of Aquarius, and represents the force the transforms Capricorn into the active + airy Aquarius. These two play a balancing game that highlights important planetary transitions across the zodiac.
Saturn's exaltation in Libra further affirms this connection and importance to finding structure and foundation even in a high-movement sign like cardinal air libra. Saturn is the force that tames Venus, just like Mars is the force that tames Jupiter. Mercury relates the lights.

A mapping effort led by @NASAGoddard's chief scientist shows how the explosive volcanic eruption at #Tonga's #HungaTongaHungaHaapai obliterated the island. go.nasa.gov/3rE8jo4
“This is a preliminary estimate, but we think the amount of energy released by the eruption was equivalent to somewhere between 4 to 18 megatons of TNT,” said Jim Garvin. 🌋
For comparison, scientists estimate Mount St. Helens exploded in 1980 with 24 megatons and Krakatoa burst in 1883 with 200 megatons of energy. go.nasa.gov/3tRKk7t

Avec la pandémie du Covid-19, j'ai plus trop envie de parler de génétique parce qu'a chaque fois, on me parle des variants et on me demande ce que j'en pense...
Or je ne suis ni virologue ni infectiologue et je fais confiance à mes confrères... Genre @nathanpsmad

CEPENDANT, la génétique du SRAS-Cov2 (c'est le nom du virus de la maladie Covid19) permet de mettre en lumière la "derive génétique" et les "pressions de sélection".
Et vous savez quoi, ces deux phénomène existe en génétique humaine !

Ce sont des phénomènes étudiés dans la genetique des populations.

Nevíme kdy a jak, ale je jisté, že i na Marsu, až tam jednou pošleme lidi, bude #smrťák úřadovat.

Dříve či později na povrchu rudé planety někdo umře.

A ač si říkáte, co jako, smrt patří k životu, pojďme si ukázat, že smrt bude trochu divná.

Proč? Protože... #vesmírníček #Mars
Zaprvé se nedá moc počítat s tím, že by někdo nebožtíka naložil do rakety a poslal zpátky na Zem. Ptáte se proč?

Protože by to bylo moc drahé a náročné.

Tělo tak téměř jistě* zůstane na Marsu

* snad jen nesmírná touha vědců prozkoumat mrtvolu v pozemských labech by to změnila
A to představuje problém. Zatímco když máte tělo na Zemi, řešení je poměrně snadné - vezmete lopatu, tělo zakopete a necháte přírodu udělat své čáry a máry - na Marsu máme problém.

Tam se příroda rozhodla "stávkovat"...

Check out our new paper in @nature. We show that at least 25% of the total martian valley network volume formed from catastrophic lake breach floods (1/10): nature.com/articles/s4158…
Valley networks on #Mars are somewhat analogous to river valleys on Earth but differ morphologically. Maybe this is a sign that instead of forming from precipitation, #martian valleys are a result of groundwater or glacial erosion, or even lava. (2/10)
Alternatively, my co-authors (Goudge et al., 2019) previously showed some valleys formed catastrophically from lake breach flooding. How do we know they were catastrophic? The downstream valley volume closely correlates with the inferred volume of water in the #paleolake (3/10)

Pushing the Frontiers of Space: Difference Between Private Space Flights of @virgingalactic and @blueorigin

weather.com/en-IN/india/sp…

- By Arunita Banerjee (@Arunita_13)

(📸: Twitter/IANS) Image
On Tuesday, July 20, 2021, the founder of Amazon, @JeffBezos, is all set to fly to the edge of space along with three others, aboard his company @blueorigin's New Shepard rocket.
Surpassing the #troposphere and #stratosphere, the space flights of @blueorigin will fly to the edge of space, about 100 km above the Earth’s mean sea level—the Karman line, also called the ‘edge of space’. Image

1⃣Remember #DishaRavi's arrest?
It happened during #Saturn & #Uranus square + mercury retrograde on #Feb 17th.
SAME astrological event will recur on #June 14th & Dec 24th.
Bt with a TWIST. Will explain in thread.

2⃣ #Mars (planet of W@R)-#Pluto opposition on JUNE 5th.
2/n
SATURN-URANUS square:
This is a v.imp transition of yr. It'll happen on
~June 14th
~Dec 24th
~Feb 17th (already took place)
Common factor btwn Feb 17th & June 14th transition is that it's happening during Mercury retro-- when it's easy to spread #FAKE NEWS. Remember T00LKIT?
3/n
Only diff is--Saturn, planet of #Karma, will be retrograde too on June 14th.
#Uranus is a planet of REBELLION, #Technology, and everything that's weird.
SATURN is associated with OLD values, system, people and also is a strict teacher.
So in FEBRUARY-- OLD clashed with NEW!

Ihr denkt, die #Grunen sind die Anti-Lobbyismus-Partei in #Deutschland? Leider falsch gedacht. Die Partei, die sich sonst gerne kritisch gegenüber #Lobbyismus zeigt, war und ist selbst auf vielen Ebenen mit ihm verstrickt, wie die folgenden Beispiele zeigen. /PN
Eveline #Lemke war Umweltministerin in #RLP. Nach nur einem Jahr wechselte sie in den #Aufsichtsrat einer Windkraftfirma. Als Ministerin förderte sie massiv den Bau von Windkraftanlagen. Hat der spätere Beruf die politischen Entscheidungen beeinflusst? /PN de.wikipedia.org/wiki/Eveline_L…
Die #Grünen zählen zu den härtesten Nichtraucherschützern. Das hinderte Marianne #Tritz, Mitarbeiterin im Büro von Fritz #Kuhn im Jahr 2008nicht, direkt von den Grünen als Lobbyistin an die Spitze der Tabakindustrie zu wechseln. #GruenerLobbyismus welt.de/wirtschaft/art…

#PlanetaryProtection has an enormous impact on interplanetary #astrobiology mission design and execution. Check out the rest of this thread for a few case studies on how it has been implemented over the years!

During the #Apollo era, it was unknown whether life existed on the Moon. To prevent contamination of the Earth’s biosphere by lunar microbes, both astronauts and the samples they collected were subject to quarantine following return to Earth.

Following splashdown in the Pacific Ocean, Armstrong, Aldrin, and Collins were transferred to a camper-like mobile quarantine facility. From there, they were transported to Johnson Space Center, where they spent 3 weeks in quarantine.

Kutálí se ze z vesmírného dvora, tááááááákle velká brambora,

Kam koukáš ty závoro?? Na tebe ty bramboro.
Kdyby tudy proletěl #Mars-ák, byl by z tebe bramborák.

How planets are connected to our senses?

I have iterated many times in past that the Vedic knowledge is very much connected to our body system and parts. Through this article, I will show you the inter-connection between our senses and planets.

This knowledge treasure can be used for solving many complex life issues & changing the whole direction of our life. Let’s have a look:
1.Sight- Your eyesight is ruled by planet #Mars (Agni tatwa). When mars is under affliction or weakly placed, it gives problems with sight.

Our eyesight is Jyoti i.e., divine light of Diya or lamp. Therefore, lightning a Diya/lamp gives a positive boost to our eyes. It also brings clarity of vision.

2.Hearing- Our hearing power is influenced by Jupiter (Akash tatwa). The weak position of Jupiter results in

Took longer than expected this. Full res sequence of @NASAPersevere descent stage departing the surface of #Mars.

So my final thread on this last full day of tweeting - and my God what a day for anyone who is interested in .... checks notes.... Mars. What I wanted to do is make a few points about journalism .... and in particular, people who write about space #Mars #JournalismIsNotACrime
To set some context, then, what exactly is a “space journalist”? It is an interesting question and one which is fairly easy to answer. As a journalist, your function is to report what happened and also why.
In that last photo, the bearded fellow at far right was one of the most extraordinary space reporters I ever met - and I was just out of shot when that picture was taken btw. Jonathan Eberhardt was an award-winning reporter -- washingtonpost.com/archive/local/…
