Eventos para Março!!
On March 4 the first quarter moon passes between Earth and the star Aldebaran, temporarily blocking our view of the star. This is called an occultation.
The occultation begins and concludes at different times, depending on where you are when you view it.
The event should be easy to see from most of the U.S., Mexico, most of Central America, the Western Caribbean and Bermuda.
Observers along a narrow path from Vancouver, British Columbia, to Hartford, Connecticut, will see the moon “graze” the star. The star will disappear and reappear repeatedly as hills and valleys on the moon alternately obscure and reveal it.
As seen from Earth, both Mercury and Venus have phases like our moon. That’s because they circle the sun inside Earth’s orbit.
Planets that orbit between Earth and the sun are known as inner or inferior planets.
Inferior planets can never be at “opposition,” which is when the planet and the sun are on opposite sides of Earth.
But inferior planets can be at “conjunction,” which is when a planet, the sun and Earth are all in a straight line.
Conjunction can happen once when the planet is on the opposite side of the sun from Earth and again when it’s on the same side of the sun as Earth.
When a planet is on the opposite side of the sun from Earth, we say it is at “superior conjunction.” As the planet moves out from behind the sun and gets closer to Earth, we see less and less of the lit side. We see phases, similar to our moon’s phases.
Mercury is at superior conjunction on March 6.
A few weeks later, the planet emerges from behind the sun and we can once again observe it. By the end of March we’ll see a last-quarter Mercury.
On April 20 Mercury reaches “inferior conjunction.”
Brilliant Venus is also racing toward its own inferior conjunction on March 25. Watch its crescent get thinner and thinner as the planet’s size appears larger and larger, because it is getting closer to Earth.
Finally, look for Jupiter to rise in the East. It will be visible all month long from late evening until dawn.

Al poseerse, los amantes dudan. No saben ordenar sus deseos. Se estrechan con violencia, se hacen sufrir, se muerden con los dientes los labios, se martirizan con caricias y besos. Y ello porque no es puro su placer, porque secretos aguijones los impulsan a herir al ser amado, a destruir la causa de su dolorosa pasión. Y es que el amor espera siempre que el mismo objeto que encendió la llama que lo devora, sea capaz de sofocarla. Pero no es así. No. Cuanto más poseemos, más arde nuestro pecho y más se consume. (…) No basta la visión del cuerpo deseado para satisfacerlos, ni siquiera la posesión, pues nunca logran desprender ni un ápice de esas graciosas formas sobre las que discurren, vagabundas y erráticas, sus caricias.
Al fin, cuando, los miembros pegados saborean la flor de su placer, piensan que su pasión será colmada, y estrechan codiciosamente el cuerpo de su amante, mezclando aliento y saliva, con los dientes contra su boca, con los ojos inundando sus ojos, y se abrazan una y mil veces hasta hacerse daño. Pero todo es inútil, vano esfuerzo, porque no pueden robar nada de ese cuerpo que abrazan, ni penetrarse y confundirse enteramente cuerpo con cuerpo, que es lo único que verdaderamente desean: tanta pasión inútil ponen en adherirse a los lazos de Venus, mientras sus miembros parecen confundirse, rendidos por el placer.
Y después, cuando ya el deseo, condensado en sus venas, ha desaparecido, su fuego interrumpe su llama por un instante, y luego vuelve un nuevo acceso de furor y renace la hoguera con más vigor que antes. Y es que ellos mismos saben que no saben lo que desean y, al mismo tiempo, buscan cómo saciar ese deseo que los consume, sin que puedan hallar remedio para su enfermedad mortal: hasta tal punto ignoran dónde se oculta la secreta herida que los corroe.

Have you noticed two bright objects in the sky getting closer together with each passing night? It’s Jupiter and Saturn doing a planetary dance that will result in the Great Conjunction on Dec. 21. On that day, Jupiter and Saturn will be right next to each other in the sky – the closest they have appeared in nearly 400 years!

For those who would like to see this phenomenon for themselves, here’s what to do:
Find a spot with an unobstructed view of the sky, such as a field or park. Jupiter and Saturn are bright, so they can be seen even from most cities.
An hour after sunset, look to the southwestern sky. Jupiter will look like a bright star and be easily visible. Saturn will be slightly fainter and will appear slightly above and to the left of Jupiter until December 21, when Jupiter will overtake it and they will reverse positions in the sky.
The planets can be seen with the unaided eye, but if you have binoculars or a small telescope, you may be able to see Jupiter’s four large moons orbiting the giant planet.

Saturn and Jupiter are easy to see without special equipment, and can be photographed easily on DSLR cameras and many cell phone cameras. Here are a few tips and tricks:
These planets are visible in the early evening, and you’ll have about 1-2 hours from when they are visible, to when they set. A photo from the same location can look completely different just an hour later!
Using a tripod will help you hold your camera steady while taking longer exposures. If you don’t have a tripod, brace your camera against something – a tree, a fence, or a car can all serve as a tripod for a several-second exposure.
The crescent Moon will pass near Jupiter and Saturn a few days before the conjunction. Take advantage of it in your composition!

Muito ☺️ fofo!! Lindo trabalho.

Sutil Sedosa Sensual
Our solar system is huge, so let us break it down for you. Here are 5 things to know this week:
1. It’s Lunacy, Whether by Day or Night
What’s Up in the night sky during November? See all the phases of the moon by day and by night, and learn how to look for the Apollo landing sites. Just after sunset on November 13 and 14, look near the setting sun in the western sky to see the moon as a slender crescent. For more, catch the latest edition of the monthly “What’s Up” Tumblr breakdown.
2. Answer to Longstanding Mars Mystery is Blowin’ in the Wind
What transformed Mars from a warm and wet environment, one that might have supported surface life, to the cold, arid planet it is today? Data from our Mars Atmosphere and Volatile Evolution (MAVEN) mission pins much of the blame on the sun. Streams of charged solar particles crash against the Martian atmosphere, and without much of a magnetic field there to deflect the onslaught, over time the solar wind has stripped the air away.
3. Orbital Maneuvers in the Dark
The New Horizons mission team has set a new record. They recently performed the last in a series of trajectory changes that set the spacecraft on a course for an encounter with a Kuiper Belt object in January 2019. The Kuiper Belt consists of small bodies that orbit the sun a billion miles or more beyond Pluto. These latest course maneuvers were the most distant trajectory corrections ever performed by any spacecraft.
4. Visit Venus (But Not Really — You’d Fry)
Mars isn’t the only available destination. You can visit all the planets, moons and small worlds of the solar system anytime, right from your computer or handheld device. Just peruse our planets page, where you’ll find everything from basic facts about each body to the latest pictures and discoveries. Visit Venus HERE.
5. Titan Then and Now
Nov. 12 marks the 35th anniversary of Voyager 1’s Saturn flyby in 1980. Voyager saw Saturn’s enshrouded, planet-sized moon Titan as a featureless ball. In recent years, the Cassini mission haas revealed Titan in detail as a complex world. The spacecraft has peered beneath its clouds, and even delivered a probe to its encounter, which will include infrared scans, as well as using visible light cameras to look for methane clouds in the atmosphere.
