Comet_Borisov_-_GIF_3.gifFrom far away: the Comet Borisov through the Solar System (GIF-Movie)279 visiteGuardate bene! EccoVi la differenza (REALE ed IN FATTO) tra un Fly-By and uno Swing-By...E senza dimenticare "Oumuamua"!
As the first known object of its type, Oumuamua presented a unique case for the International Astronomical Union (IAU, for short), which assigns designations for astronomical objects. Originally classified as comet C/2017 U1, it was later reclassified as Asteroid A/2017 U1, due to the absence of a coma (--> "Chioma", in Italian).
Once it was unambiguously identified as coming from outside the Solar System, a new designation was created.
The name comes from the Hawaiian word "oumuamua", meaning 'scout' (from ou, meaning 'reach out for', and mua, reduplicated for emphasis, meaning 'first, in advance of', and reflects the way this object is like a scout or messenger sent from the distant past to reach out to Humanity.
It roughly translates to 'first distant messenger' (or "The First Messenger from the distance").
Before the official name was decided upon, the name "Rama" was suggested by the name given to an Alien Spacecraft discovered under similar circumstances in the 1973 science fiction novel "Rendezvous with Rama", by Sir Arthur C. Clarke.MareKromium%29/%01/%21, %09.%GenAnakin: In effetti molto acuto. Ha fatto quasi un'inve...

Asteroid_DD-45-a.gifAsteroid 2009 DD-45 (GIF-Movie)72 visiteUn bellissimo GIF-Movie; da notare ed apprezzare il movimento irregolare dell'asteroide il quale, pi che "ruotare" su se stesso, sembra "rotolare" (come fa la Luna Saturniana Iperione).
Il movimento (se non altro apparentemente) caotico dell'asteroide DD-45 attorno al proprio asse di rotazione pu essere spiegato non solo dalla forma irregolare ("a tubero") posseduta da questo minuscolo Corpo Celeste, ma anche dalla marcata influenza mareale (---> gravitazionale) su di esso esercitata dalla "vicina" Terra (distante circa 70.000 Km).MareKromium%21/%01/%21, %18.%GenMareKromium: Sacrosante Parole!!!

Comet_Oumuamua-2.jpgOumuamua (large)150 visiteQuesto l'ingrandimento dell'immagine profonda di prima. Sempre al centro, l'asteroide interstellare "Oumuamua", circondato dalle tracce di stelle deboli prodotte poich il telescopio insegue l'asteroide in movimento (rispetto alla stelle cosiddette "fisse"). L'immagine ottenuta combinando numerose immagini del VLT (Very Large Telescope) dell'ESO e del telescopio Gemini South. L'oggetto indicato con un cerchio blu e appare come una sorgente puntiforme, senza polvere diffusa.MareKromium%21/%01/%21, %16.%GenMareKromium: ...senza parole...
