GIANT PINK PLANET!!

Using infrared data from the Subaru Telescope in Hawaii, an international team of astronomers has imaged a giant planet around the bright star GJ 504. Several times the mass of the Jupiter and similar in size, the new world, dubbed GJ 504b, is the lowest- mass planet ever detected around a star like Sun using direct imaging techniques...

Glowing a dark magenta, the newly discovered exoplanet GJ 504b.

.......................AMAZING!!!!!!........................

• MERCURY is the fastest planet. Mercury zooms around the Sun in just 88 days, at an incredible 173,000kph. That makes it faster than any space rocket ever invented.
• OLYMPUS MONS situated in Mars is the largest volcano in Solar System which is about 600km across and towers over 25 km high.
• You could fit two EARTHS inside THE GREAT READ SPOT, which is about 40,000 km across.
• GANYMEDE is the largest moon in the SOLAR SYSTEM.
• CALLISTO is the most cratered world in the SOLAR SYSTEM.
• Summer at South Pole of URANUS lasts for 42 years.
• TRITON is one of the coldest place ever recorded!!! The temperature is -236 degrees Celsius.
• PLUTO  is smaller than a country. At 2,360 km across, it is smaller than US or RUSSIA.The first living creature in space was a Russian dog, called Laika. She made a 7 day journey in the space capsule SPUNTIK 2 in November 1957.
• NEUTRON STARS are super-heavy!!! They may be 20 km across, but they weigh 50 times more than planet EARTH!!!

How long is a day on each planet? How long is a year??

A day is the time it takes a planet to rotate once. Earth takes 24 hours. Since each planets rotates at different speed, the length of the day differs. A year is the time a planet takes to rotate around the sun in Solar System. Earth takes 365 days to revolve around the Sun. Each planets revolve around the sun at different speeds.
Here is the time taken by each planet to rotate and revolve. The time is given in Earth days, Earth years and Earth hours.

What do you think the density of a Black Hole would be???????

******FORMATION OF SOLAR SYSTEM******

SOLAR SYSTEM

Our universe was born from the BIG BANG about 13.5 million years ago. The first stars lived out their lives and eventually exploded, sending "STAR STUFF" out into cosmos. Our SUN is thought to be a third-generation star and our entire solar system is made of the recycled star stuff of previous star generations.
 Our SOLAR SYSTEM began forming about 4.6 billion years ago within a concentration f interstellar dust and hydrogen gas called Molecular Cloud. The cloud contracted under its own gravity and our pro to-Sun formed in the hot dense center.
The remainder of the cloud formed a swirling disk called the SOLAR NEBULA where the planets were formed including planets Eris and Pluto.
