Earth- Dude, what do you think of those cosplays?
Sun- They rock!
Kepler-452b (just discovered rocky planet)Dude, what do you think of those cosplays?
Kepler-452 (star)- They rock!

 In the meanwhile

Bernard- Thanks Kepler, finally my estates over there will be worth some money!
Kepler (NASA space probe)-You're welcome Berny... I want the 50%
Bernard- Damn...


Kepler did it again!

Pluto- Oh great, first I'm diminished to "dwarf", and now -thanks to you, damn snoop- I'm gonna end up on some cheesy Valentine's Day card!
NH- See ya dwarfy... Buahahahaha...

Congrats New Horizons!

LA TERRA, LA MATERIA OSCURA E IL VIAGGIO GALATTICO VERSO L’ESTINZIONE DI MASSA


Via Lattea e Sole
Via Lattea img adatt. da SM
È possibile che esista una relazione diretta tra le estinzioni di massa, la caduta di comete e gli sconvolgimenti geologici che si sono verificati sulla Terra nel corso del tempo e il passaggio ciclico, ogni 30-40 milioni di anni, del Sistema Solare attraverso il piano della Via Lattea e lo strato di materia oscura che esso contiene. A suggerirlo è il biologo statunitense Michael Rampino in un articolo pubblicato sul giornale scientifico Monthly Notices of The Royal Astronomical Society.

Mi si consenta di sottolineare che la "Materia Oscura" di cui tanto si blabbleggia in questo podcast a dir poco ridicolo per quanto è superficale nella trattazione dell'argomento, ecco, dicevo, mi si consenta almeno di precisare che la suddetta "Materia Oscura" di cui si parla nel suddetto podcast (e quindi nell'articolo di riferimento) è ritenuta essere fatta di WIMPs, e non di MACHOs. Per una trattazione finalmente professionale della faccenda "Materia Oscura" e delle sue declinazioni WIMPs e MACHOs si veda qui e qui

THE EARTH, THE DARK MATTER AND THE GALACTIC TRIP TOWARD MASS EXTINCTION


Milky Way and Sun

A direct link can exist among catastrophic geologic events, comet impacts, mass extinctions and the Earth crossing, every 30-40 million years, the Milky Way’s mid-plane and its clumps of dark matter. The hypothesis is discussed by the American biologist Michael Rampino in a paper published in the journal Monthly Notices of The Royal Astronomical Society.

The following text is that of the podcast
in Eng?ish


O-oooooh hallo dear English-hearing-speaking-thinking listener welcome to the second of my podcast in Engmark, that is "English-question mark" (i.e. Eng?ish), a language that is to proper English what a three tons mean black rhino is to a fluffy puffy little puppy. Well, or vice versa.
 

The voice you’re hearing is that of my avatar, a dumb human controlled via a wireless-voodoo trick by me, “sciencemug”, the blog which tells you about science, distracts the monster under your bed luring it with a box of donuts inside a box of tacos inside a box of bacon inside a box of pizza aaand which dances the steps of light and breeze with the demons in your head so you can have a full night of good solid sleep (unlike the monster under your bed that, in the meanwhile, given all the stuff it gulped down, will be spending the whole night painfully barfing in its bathroom, which, by the way, is right under your bathroom).
 

Sooo, where were we at? Ah, yeah, right, podcast in Engmark, black rhino, avatar, I am sciencemug the blog… What else? Oh right! The topic of today’s podcast! Well, dear listener, here it comes!
 

Today I’ll tell you a story about Earth, dark matter, and a cosmic travel toward mass extinction… Uuuuuh, spooky!
 

A direct link can exist among catastrophic geologic events, comet impacts, mass extinctions and the Earth crossing, every 30-40 million years, the Milky Way’s mid-plane and its clumps of dark matter. Professor Michael Rampino, a biologist of the NY University who collaborates with NASA, finds this possible link after analyzing data from studies of the last 30 years in the fields of astronomy, geology and biology. Professor Rampino’s findings are published in the journal “Monthly Notices of The Royal Astronomical Society”.
 

Ok, done, that’s it dear listener. Now let’s switch to chat about mushrooms and how to mix ‘em with French fries and vanilla ice-cream to create a very original wedding dress/combat suit for red ants of Papua New Guinea, ok? No? Are you sure? Still into this professor Rampino’s story? Oh well, you are the listener, so you decide.
 

So let’s start with some preliminary information before digging any further into Rampino’s paper, alright? Ok.
 

Our galaxy, the Milky Way, is a flattened spiral, so from a side view, well, it looks like a disk, or a funny pizza in case you look it when you’re particularly hungry, at least that’s what Silver Surfer said at the custom agents who interviewed him the first time he came by, and you got to believe a bald dude made of precious metal riding a space surf-table, right? I mean, who can be more reliable than a folk like that? Right?
 

Anyway, galaxy-flattened spiral-disk.

So, this means our galaxy has a mid-plane. Besides,
