Vela PulsarThe Vela Pulsar (PSR B0833-45 or PSR J0835-4510) is a
radio, optical, X-ray and gamma-emitting pulsar associated with Vela Supernova Remnant, in the constellation of Vela.
Note that this object has often been called Vela X,
for reasons that appear historically unclear.
In early 1970, Curtis
proposed the presence of a planetary companion to explain certain variations observed in pulsar timing.
Such putative object would have a mass of 0.01 Solar masses (i.e 10 times the mass of Jupiter) and be located at 0.3 Astronomical Units from the pulsar. Accounting the age of such article, it's likely
this candidate might turn out spurious or at least unconfirmed.

Vela X is a strong radio pulsar source, that is also associated with a very strong 100 MeV gamma-ray source, and the rather weak Uhuru X-ray source 4U 0833-45. It is isolated, and should not be confused with the very different strong accreting, pulsing, eclipsing binary X-ray source Vela X-1, also known as 4U 0900-40, and which is associated with the supergiant star HD 77581.
Both objects are of high intrinsic interest, and extensively studied.G.Michanovsky (1980) wrote about
the probable significance of Vela X in prehistory.

The theory of G. Michanovsky Michanovsky
The researcher George Michanovsky instead takes the moves from a legend (presumably Indo-European) common to the Mediterranean countries and those of the North Sea.
According to this legend a star (Vela X) would move beyond the southern end of the horizon, becoming visible in the northern hemisphere and from this position would dominate the entire sky: it was called the "Star of Atlantis" or "Cross South. " And it also speaks of Amerigo Vespucci as a great desire to be fulfilled: the official iconography of the browser displays it in the act of gazing at a starry sky in which stands the Southern Cross
Michanovsky reminds us that the navigator had explored the mouth of the Amazon used the name of 'river of fire hidden.
Sabatino Moscati, in turn, makes us reflect that:
"If Plato's story, as it is formulated as a whole and must be regarded as a legend,
the fact remains that the legend might have historical foundations and concrete that has contributed to its creation that the memory of actual events, even if those events may have been multiple, differing in time and space produced by the imagination. "

Crux - Southern CrossCrux is sometimes confused with the nearby False Cross by stargazers. Crux is somewhat kite-shaped, and it has a fifth star (ε Crucis). The False Cross is diamond-shaped, somewhat dimmer on average, does not have a fifth star and lacks the two prominent "Pointer Stars."

False Cross - Constellation VelaThe False Cross is an asterism formed of the stars δ Velorum and κ Velorum and ι Carinae and ε Carinae.
It is so called because it is sometimes mistaken for the Southern Cross, causing errors in astronavigation.
