New- Star Chart For Cayman

A new feature as of June 2015 has been added - look at the bottom of this web page and there is a new Star Chart exclusively for Grand Cayman

Sunday 14th October 7.00 p.m. Pedros Castle



Directly overhead as darkness falls can be seen the distinctive shape known as the Summer Triangle, which consists of the stars Vega, Deneb and Altair. This noticeable pattern is known as an astronomical asterism, a group of stars seen in Earth's sky which is not an official constellation. The triangle connects the constellations of Aquila, Cygnus, and Lyra.
The largest of these three constellations is Cygnus, the Swan, also known as the Northern Cross. Cygnus contains several bright stars.
Deneb, α Cygni, is an extremely brilliant star, very prominent despite its distance (3230 light years). The blue supergiant forms the swan's tail, the upper end of the Northern Cross. It’s also the 18th brightest star in the sky.
Albireo, β Cygni, is at the swan's beak. It is one of the most beautiful double stars of the sky, a golden star easily distinguishable in a small telescope from its blue companion.
Lyra, dominated by its bright star Vega, is a much smaller constellation than Cygnus.
Vega is the second brightest star of the northern hemisphere (after Arcturus) and the fifth brightest star in all. It lies at a distance of only 25.3 ly. It was the first star to be photographed.
Aquila is a much harder pattern to distinguish, although Altair is easy to spot. Altair is located 17 light years away from Earth (about 159 trillion kilometers) and is one of the closest stars visible to the naked eye.
Behind the Summer Triangle lies some of the vast star fields of our Milky Way Galaxy, containing literally billions of stars. The dark band across the middle that seems to divide the stars is actually interstellar dust, which absorbs more visible light than it emits and so appears dark.
Jupiter is the only visible planet in the evening sky this month, shining bright in the south west.
Autumnal equinox falls on the 23rd, when the Sun can be observed to be directly above the Earth's equator. Night and day are nearly of the same length, and this signals the end of the summer months and the beginning of winter.

...interstellar travel (thousands G of constant acceleration)... gravitation, dimensions and inertia: the Matter... The electromagnetic radiation: quanta (pieces) of energy in discrete amounts (minimum and independents), photons, which move in waves... Why energy quanta (photons) are attracted by gravitational fields of "stellar lenses" curving their trajectories and move on?...go ahead because they have inertia...and are attracted because the Energy also has Gravitation, but does not manifest because it no emits Gravitons, or emits in imperceptible degree, because it has to be condensed enough like in matter for that, but it is sensitive to Gravitation from Matter emits... Energy and Gravitation "associated"...and...the Gravitational Force is another manifestation, unknown yet, from Energy...(no "curvature" of that called "space-time" relativistic)... When was finished contraction, F=G((m1*m2)/d²), the pre-early Universe; (no relativistic "singularity", but it was a Sphere with dimensions and outside the Infinite Empty Space); was need have as its starting point towards the expansion, one first action: when all Universe´s Matter was almost infinitely compressed and hot with all subatomic particles in direct contact without empty space among them, then →Gravity← becomes ←Antigravity→, those hyper-dense Matter becomes Energy ("infinites": Temperature + Energy + suddenly Antigravity = Big-Bang)...already again how a New Universe in expansion cooling, appears again the Matter from Energy...and again antigravity becomes normal Gravity... Its particle exchange, the theoretical Graviton yet...maybe "quanta of gravitational energy"... The Energy (e=mc²) is sensitive to Gravitation but hardly emits Gravitons... The Matter, which is condensed Energy (m=e/c²), emits now Gravitons proportionally to its density... The Matter with normal density, naturally, emits few Gravitons (weak intensity of gravitational force). But...if someday could transform some of matter, not in Energy by annihilation with antimatter but entirely in Gravitational Force with an exponential Gravitons (or antigravitons) emission...would have a way to amplify the Gravitational Force a certain amount of mass... Light (photons) can be directed with a mirror... Gravity (gravitophotons) perhaps also can be directed someday the same such as light in a car´s headlight placed in ceiling looking downwards... This would be necessary for having artificial gravitational attraction only toward the ceiling in all the floors of the ship, each down´s floor must have less own gravity-power because receives gravitational attraction from all up´s floors. This can be difficult to observe in Universe because, although with unequal intensity, there are Gravitational Forces actuating from all directions. But in...gravitational transformers...for spacecraft to thousands G of constant acceleration...

(2)...interstellar travel (thousands G of constant acceleration)... The Electromagnetic and Gravitational Forces have some obvious similarities (fulfill the Law of Inverse of the Square) as both are "inversely proportional to the square of the distance that separate"...distance between the poles of two magnets the Electromagnetic...and distance between the centers of two masses the Gravitational... Just as now can using the Electromagnetic Force for obtain different voltages, currents and electrical powers...electrical transformers...perhaps someday when that mysterious Gravitational Force reveal its secrets, can also using it and amplify its emission (converting the mass exponentially in Gravitons) somehow for obtain different intensities and gravitational powers...gravitational transformers... Spacecrafts with indestructible structures and the distribution of a building of housing flats (where are the foundations would the nozzles)... Antigravitational fields directed forward would go shoving and accelerating the space´s dust until reaching (the dust) almost ship-speed the dust´s cloud matter-feeder ("fuel") always placed at ship´s front, leading dust with Gravitational peripheral fields; already the dust with slow differential-speed between dust and ship (each dust´s particle already does not is a bullet); towards the ship converters matter/antimatter, where at half of matter would transform in antimatter to feed the insatiable demand for the voracious annihilation rocket engines ejecting the appreciable mass of the Pions, produced in large quantities, through the nozzles to the speed of light...a rocket´s thrust = ejection by nozzle (mass*speed) in each second...and maintaining indefinitely to the ship at thousands G of constant acceleration... Powerful gravitational fields inside the living areas would counteract the HUGE CONSTANT ACCELERATION of the ship, keeping them to 1 G...

...space-elevator (orbital station bike wheel-1g)... geostationary orbit, a huge "bike-wheel" is gyrating around its own axis for have 1g-centrifugal. Wheel held in place with 4 CABLES (each cable with a track for Train, for both trains crossing ↓↑) FORMING THE STRUCTURE OF A RHOMBUS♦ (minor diagonal of rhombus is the gyration-axis of the Station-Wheel)...rhombus´s below, the carbon nanotubes Track towards Earth...rhombus´s above, the Cable towards a higher counterweight...if...WHEEL´s RADIUS = 250 mts... Wheel gyration´s Axis length = rhombus´s minor diagonal = ½ Wheel´s radius = 125 mts (axis could be a resistant hollow tube with for example 20 mts in diameter with an adequate wall´s thickness, hollow which could serving how tank of anything, e.g. air, or tank of frozen water storage no totally full, for volume expansion from liquid to ice without tank, Axis, breaking, thawing using solar-heat)... Cable´s length of the rhombus´s side = Wheel diameter = 500 mts ((also how Wheel´s supporting, instead of a rhombus, can be a narrow Rectangular structure ▄▄▄▄▄▄ of rigid girder with dimension sides slightly majors than Wheel´s diameter and wide, e.g. Wheel´s diameter 500 mts and wide 50 mts...rectangle´s sides: 510 mts length, 60 mts wide. Rectangle with a cable/track (length=Wheel´s diameter) in each vertex, forming a long isosceles triangle ──────◄at both rectangle´s minor sides►──────)). Wheel´s ZONE-1g: habitable length = 1571 mts*50 mts wide (separation at both sides between Cable and Circumference of the gyratory Wheel, approx.= 5 mts, adjusting this separation installing an Axis with major or minor length, as much as shorter Axis...stronger and, for easy train´s passing, an angle nearer to 180º value in both rhombus´s vertex, minor diagonal, where are the Big Soundless-♫-Bearings of Axis´s insertion...a few Electrical Motors fed with Solar-Energy maintain automatically the gyration-speed counteracting the slow braking by friction from the Bearings...besides of Bearings: main Maglev system also for the gyration and Axis´s supporting, leaving the Bearings only how secondary security system...with a slight roominess between each Bearing and its exterior subjection, into the roominess all around...little solid Pistons radial extensible and retractable...

With a sufficient cables tension coming from the counterweight, if Axis resists: the rhombus structure is undeformable)*10 Floors with 25 mts in height each one, gyrating 360º each 31 seconds, angular-speed = 11.61º/sec, linear-speed (tangential) = 182 kms/h... Station-Wheel´s GYRATION: AXIS IN PERPENDICULAR (90º) ORIENTATION TO THE ORBITAL TRAJECTORY...and so, while Station-Wheel follows its geostationary orbit, the Wheel does Not changes the spatial-orientation of its axis, and thus there are Not Precession forces actuating (and thus there is Not torsion´s force against Track)...

(2)...space-elevator (orbital station bike wheel-1g)... Wheel with maneuver´s tangential-rockets for gyration´s start, or...gyration emergency stop...and maneuver´s axial-rockets for reorientation of Wheel´s axis, if it is necessary: because the Earth´s axis slightly and very slowly goes oscillating cyclically due to nutation and precession...that oscillation evidently produces transversal traction pulling of the Track towards aside from its anchoring on equator, thus would have an also slight pendular movement side to side and it would produce precession´s movements of the Wheel´s axis and thus a not wished torsion of the Track...but the system must supporting lateral charges, in the same orbital plane and thus without precession´s problems on the Wheel´s axis, of acceleration against W→Track←E produced by the Coriolis effect when movement´s direction is perpendicular to the gyration´s axis, that lateral charge is maximum on equator (there, a vertical movement is perpendicular tø Earth´s axis) and zero on Poles (there, a vertical movement is parallel tø Earth´s axis); upwards charge to West, downwards charge to East; the gyroscopic-rigidity contributes for maintaining the gyration-axis perpendicular to the orbital trajectory... When the Maglev Train slowly arrives (Train with one opened ╚╝ side in its technical maglev-zone train´s all along over Track for can passing for both tracks: main-Track/rhombus-track/again main-Track), using now cogwheels on Zipper-Track (zippers installed on the same Maglev-Track), Train stops in Geo 0g-Station placed over one Extreme of the Gyration-Axis, next to «Port for Spacecrafts»... Passengers disembark and entering into gyratory circular corridor, they take now the interior-elevator of one of the Wheel´s hollow-radius (also could be an exterior-elevator running for a simple zipper-radius), and tunnel "descending" till Hotel into the final Zone-1g...where while Station-Wheel goes turning, the immense O2 producer Hydroponics Garden receives a filtered Sun light...and there are Earth´s awesome views.
