What does space smell of?

Thanks to an orbiting astronaut, we now know the answer, and it is even stranger than you might expect
.Astronauts say the unique smell aboard the International Space Station is reminiscent of two things - meat and metal.

It has been described as like 'seared steak', 'hot metal' and welding fumes'.

Astronaut's have largely agreed on the scent.

Three-time spacewalker Thomas Jones said returning to the ISS, 'carries a distinct odor of ozone, a faint acrid smell.' and is 'sulfurous'.
                             


                                 The March 11,2011  magnitude 9.0 earthquake in Japan may have shortened the length of each Earth day and shifted its axis. But don't worry—you won't notice the difference.

                                 The calculations also show the Japan quake should have shifted the position of Earth's figure axis (the axis about which Earth's mass is balanced) by about 17 centimeters (6.5 inches), towards 133 degrees east longitude. Earth's figure axis should not be confused with its north-south axis; they are offset by about 10 meters (about 33 feet). This shift in Earth's figure axis will cause Earth to wobble a bit differently as it rotates, but it will not cause a shift of Earth's axis in space—only external forces such as the gravitational attraction of the sun, moon and planets can do that.

Do you know Jupiter is a gas planet?

Jupiter has no surface for a spacecraft to land on because it is made mostly from helium gas and hydrogen. The massive pull of Jupiter’s gravity squeezes the hydrogen so hard that it is liquid.

          Jupiter is about 90% hydrogen and 10% helium  with traces of methane, water, ammonia and "rock". This is very close to the composition of the primordial Solar Nebula from which the entire solar system was formed


This hypothetical cosmic body acts in the exact opposite manner of a black hole. Instead of pulling in matter, a white hole expels it like a sort of cosmic exhaust valve, giving off serious amounts of energy. Some cosmologists theorize that a black hole in one universe might empty out through a white hole in another universe. In these theories, the black hole acts as a kind of tunnel -- instead of pulling in matter that collapses into a single point, the black hole shuttles the matter right through the tunnel and out the white hole on the other end . In other words, the matter that comes out of a white hole is the matter that fell into a black hole.

The Sun provides our planet with 126,000,000,000,000 horsepower of energy every day. This means that 54,000 horsepower is delivered to every man, woman and child on earth in each twenty four hour period. This amount of energy equals only about two billionths of the total energy broadcast into our solar system by the Sun each day.

Neutron Stars Are Very, Very Heavy

Neutron stars are only about 10-13 miles in diameter, they are heavier than many stars. A thimbleful (very small amount) or sugar cube, amount of a neutron star weighs around 100 million tons. That’s more than a large mountain.

Now researchers from NASA have discovered evidence that the planet may harbor pockets of water ice, along with organic material, in several permanently shadowed craters near its north pole.
New data from NASA’s MESSENGER spacecraft reveal bright spots (shown in yellow) on Mercury that are almost certainly ice.
