Kenapa Akhir - akhir ini Jakarta Panas?

Jakarta Bagi Anda yang tinggal ataupun beraktivitas di Ibu Kota tentu mengalami cuaca yang sangat panas dalam beberapa hari terakhir ini. Kondisi seperti ini pun diperkirakan masih akan terjadi dalam beberapa hari ke depan. Ada apa sebenarnya?


Cuaca panas yang melanda Jakarta beberapa hari terakhir ini ternyata disebabkan sulitnya pembentukkan awan. Kasubid Informasi Meteorologi Publik Badan Meteorologi Klimatologi dan Geofisika Hari Tirtodjatmiko mengatakan hal ini karena kekeringan yang terjadi di ketinggian 10 ribu kaki di atas permukaan tanah atau di lapisan 700 milibar seluas 40%.

Hal tersebut terjadi karena adanya bibit badai di belahan bumi utara sekitar laut China Selatan dan di Samudera Pasifik atau sebelah timur Filipina. Hal ini menarik massa udara yang sedianya terbentuk di Jakarta. Ini biasa terjadi pada bulan September," jelas Hari di Jakarta, Rabu (9/9).

Penyebab kemarau, kata dia, adalah akibat angin yang berhembus cukup kencang dengan kecepatan di atas 10-15 knot atau sekitar 8 km per jam. Sehingga awan lembab sulit terbentuk. Kondisi ini, kata Hari, diperkirakan akan berlangsung hingga beberapa hari ke depan. "Cuaca jadi sangat terik dan kering, apalagi sekarang sedang kemarau," katanya.

BMKG memprediksi, cuaca kemarau untuk Jakarta bagian Selatan seperti Depok, Bogor, dan Jakarta Selatan akan berakhir pada Oktober-November 2009. sedangkan untuk Jakarta bagian Utara, kemarau diprediksikan berakhir pada November-Desember.

Meski masih musim kemarau, namun panas yang terjadi di Jakarta masih terbilang normal antara 32-34 derajat celcius. Dia menyarankan masyarakat Jakarta banyak mengonsumsi air putih agar terhindar dari gejala dehidrasi. "Untuk nelayan dengan cuaca seperti ini tidak ada masalah,"

THE SUN
The sun is the center of our solar system. The solar system consists of the Sun, nine planets (one of which is the Earth), and all other objects that are running circle around the sun. The sun is a ball of hot gas. The disk of the sun is blinding, where light and heat radiate asala, called the photosphere. Surrounding photosphere is a layer of gas called the chromosphere is a brilliant red. Untain red hydrogen light was thrown as far as hundreds of thousands of kilometers into space from the chromosphere. This thread disebuah Prominensa. There is a layer of gases surrounding chromosphere another called Korona. Surface of the sun marked the spots called sunspots bleak. It can be seen with special telescopes.

Understanding / Definition Meteors, Meteorites, Comets, Satellites, Stars & Planets - Solar System Astronomy Basic Education Physics 
Here below is a simple basic meaning of the heavenly bodies are frequently encountered in daily life, the meteors, meteorites, comets and satellites:
A. Meteor
Meteor is the celestial bodies that enter into the realm of Earth's atmosphere, which caused friction with the air metor surface at high speed. Due to the friction that is causing rapid heating and light a fire in the distance we see as shooting stars.
B. Meteorites
Meteorites are objects in space at a rapid pace. The number of meteorites through the sky does not count because it is very much with different shapes, types, ingredients, color, nature, and so forth.
C. Comet
Comets are celestial bodies that orbit the sun. Comets have orbits own orbit is oval shaped. Comets are commonly referred to as shooting stars because of its bright glowing gas and dust have the tail very long.
D. Satellite
Satellites are objects that orbit around the planet that has its own circulation. That surrounds the planet with satellites together around a star. The Moon is a natural satellite owned by the earth along the earth around the sun, while satellite palapa, satellite b1, and so is man-made satellites are used for specific purposes such as for communications, spies, research, and so forth.
E. Star
Stars are celestial space which has a large size and emit light as a light source. The nearest star to Earth is the sun. The sun surrounded by planets in the solar system as planets Earth, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune and Jupiter.
F. Planet
Planets are celestial bodies that surround the star as the center of the solar system. The planet can not produce its own light but can reflect light. Planets close to Earth every day we can see with the naked eye as the planet Venus is called the morning star.

Goodbye Pluto!
 

Starting on Thursday (24/8) Do not ever say the Planet Pluto slip. Because ever since that day, Pluto was no longer entitled to the title as the planet.

General Assembly of the International Astronomical Society (International Astronomical Union / IAU) to-26 in Prague, Czech Republic, which ended August 25, resulting in a world of astronomy's historic decision to remove Pluto from the list of planets in our Solar System. From now on, members of the Solar System consists of only eight planets, namely Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

 
Issued a decision that Pluto is a planet of the Solar System Family member for 76 years is a consequence of the enactment of a new definition of planet. General Assembly of the IAU Resolution 5A-26 to contain the new definition.

The resolution stated, an object can be called a planet where the sky meets the three conditions, namely orbiting the Sun, is large enough so as to maintain a round shape, and have orbital paths are clear and "clean" (no other celestial bodies in orbit is).

The definition is the first universal definition of the term planet since the planet is known among astronomers, even before the era of Nicolaus Copernicus in 1543 proved that Earth is one planet that rotates around the Sun.

With the new definition, Pluto is not entitled to the name of the planet because it does not meet the third requirement. Pluto's orbit of Neptune's orbit so that the cut in his travels around the Sun, Pluto is sometimes closer to the Sun than Neptune.

TYPE SPACE ROCK BAND

If you’ve heard some of the Harmonix-associated bands who’ve made it into Rock Band, you might assume that we spend all our time playing guitars, pumping our fists. And of course, you‘re right…up to a point. But this place is a hotbed of musicians, and our taste can get pretty far-ranging. Lots of us are into hip-hop, electronica, and other sounds that wouldn’t  fit so easily into the game.

Presenting Oxytocin, a fresh compilation of some of the more exotic music to come out of Harmonix. You’ll hear a few guitars, but there’s lots more: Socially conscious hip-hop, adventurous loop-and-sample tracks, soaring electronic pop, and then some. Most of all, you’ll hear what happened when a few of our creative types looked around, bonded over their left-of-center tastes, and let the creativity flow.  The title, by the way, refers to a chemical that music triggers in the human brain—nothing to do with that stuff they’re stealing down the street.

Milky Way Galaxy
There is nothing more mysterious and fascinating look at the sky apart from the galaxy,which stretches like a strand of jewels from one end of heaven to the other end of the sky.In the olden times, when people look at this great show, they were filled with awe of its beauty just like us. But because it does not really know what it is, they make all sorts ofweird and wonderful explanation of the galaxy.

Our galaxy is roughly shaped like a watch, round and flat. If we can rise above it andlooking down, the galaxy looks like a great watch. But we are now in this galaxy, and if we look to the means we look toward the edge of the "watch" it. Thus, we see that the edgethat surrounds us. And because there are millions of stars in it, we see that as the Milky Way galaxy.

Note that there are at least three billion stars in the galaxy. And here's an idea of ​​its size.It takes eight minutes for light from the sun to reach earth. The galaxy rotates on its headlike a wheel. From our position in the galaxy, would require approximately 200 millionyears only to make one revolution. Galactic year is defined as the time it takes the sun to circle the galaxy is about 240 x 10 ^ 6 years. The calculation of the mass of the galaxy, can also be done by Kepler's formula.

Name of the Planet's Largest

 

Planets are celestial bodies that orbit around a star. The planet has enough mass to have its own gravity to overcome rigid body so that the pressure of the celestial body has a shape of hydrostatic equilibrium (nearly round shape).

Planet in the solar system at this time there are nine known planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto. From the ninth planet Jupiter is the largest planet.

HOW DID EARTH GET HERE ?


Of all the questions that humans face, the question of how the Earth formed is one of the most challenging, and different theories that human beings have been formed over the years on creation of the planet is often generated much controversy.
While scientists today believe that they finally found the answers to the most basic question, it is important to remember that the previous generations, people and culture they assumed that the answer to this question is correct in their day as well. Here is some basic information about the most popular theory of how the Earth formed.
Development of our planet began about 4.6 billion years ago, and the Earth has undergone a startling change in geology since then. Earth has existed in some form for about a third of the history of the universe itself. Our home planet formation starts with the early Hadean era, in which a  
variety of solar debris accumulates into a world that is increasingly crowded.
Very little of it exists in its original form today, but scientists have concluded that the main ingredient is the bedrock and the crystal. At some point during this era, the young Earth to form the first coat just before colliding with another large protoplanet, and many of the problems on our planet was formed by this event. In the chaos that followed, the Earth is setting the violence that is constantly bombarded by meteorites and volcanoes was rocked by a great and constant.
As the planet cooled, and things began to settle, the Earth entered the Archaean era. It was during this period that our atmosphere was created, but the total absence of the ozone layer and the scarcity of oxygen means that it will be a difficult place to survive. However, the first fossils began to emerge during this time, and with it the story of life on Earth began. At this time, the Earth is big enough to pull the building blocks of life to the field of gravity, and accumulation of water started to create a big ocean and sea.
In these waters, life is slowly growing, and the possibility that the early days of evolution, including the world's lifeforms are even more diverse than the world today. Some lifeforms found a way to build and store energy through the use of sunlight and the abundant carbon dioxide, and oxygen created by the basic form of photosynthesis is allowed to continue down the path of evolution for the curious.
