Interesting Facts About Space And Exploration Of The Universe
The most far known objects in our universe are quasars which are matter breaking apart as it spirals into a black hole the nearest one is billions of light-years away quasars are one of the most ancient powerful luminous and energetic objects tone in the universe emitting up to 1,000 times the energy.
The output of the Milky Way which contains 200 to 400 billion stars in 2015 astronauts ate food that had been grown in space for the first time as part of NASA's experiment they sampled red romaine lettuce that has been growing in a specially designed chamber the astronauts only got to eat half the lettuce.
The other half was sent back to earth for scientific analysis if the experiment is successful it could be a relatively easy way of adding some freshness and variety to the space fare while early spacesuits were built entirely of mushy fabrics today's emu has a combination of soft and hard components to provide support mobility and comfort the suit itself has 13 layers of material including an inner cooling garment pressure garment thermal micrometeoroid garment and outer cover.
The production of the entire suit costs about twelve million dollars, and seventy percent of that cost is for the backpack and control module Great Red Spot is an atmospheric storm that has been angry in Jupiter's southern hemisphere for at least four hundred years about a hundred years ago the storm covered over 40 thousand kilometers of the surface and was big enough to engulf 3 Earth's currently.
It's about half of that size and seems to be shrinking winds at the very edge of the storm gusts to 432 kilometers an hour but inside the storm seems to be somewhat stagnant with no inflow nor outflow Galileo Galilei is often incorrectly credited with the invention of the telescope instead historians now believe that the Dutch eyeglass maker Johannes Lippershey is its creator Galileo was however probably the first to use the device to study the heavens Jupiter's moon Ganymede is the largest satellite in the solar system
Larger than Mercury and Pluto and only slightly smaller than Mars it would easily be classified as a planet if it were orbiting the Sun Ganymede was discovered by Galileo Galilei in 1610 the discovery along with three other javea moons was the first time a moon was discovered orbiting a planet other than Earth nobody knows how many stars there are in the Milky Way estimates range from 100 billion to 400 billion, and the Milky Way is just one of a hundred and forty billion galaxies.
Many of them are larger than ours the largest galaxy, I see one 1:01 has over a hundred trillion stars similar galaxies like the large melon Janet cloud have about 10 billion stars the most stars a person can see from any point at earth are about 2500.
The International Space Station is the most expensive object ever built with a price tag of 160 billion dollars this impressive build is 171 feet long 240 feet wide and 90 feet high there's a total of 15,000 cubic feet of space inside and it weighs a whopping four hundred and twelve thousand pounds, fortunately, the ISS is production costs.
This share among the many participating countries which includes Canada the European Union Japan Russia and the US light speeds along at 186,000 miles per second, so everything you see took place a short time ago you see the moon as it was one and a quarter seconds ago and the light left most stars tens or even hundreds of years ago.
For example, when you look at the dramaturg galaxy which is 2.3 million light-years away from the light you are seeing took 2.3 million years to reach you the largest known star is called the pistil star it is believed to be a hundred times as massive as our Sun and 10 million times as bright in 1990, a star named the pistil star was known to lie at the center of the pistil nebula in the Milky Way galaxy in 1995.
It was proposed that the pistil star was so huge it was throwing off a mass that created a pistol nebula observations from the Hubble telescope in 1997 confirmed the relationship between the star and the nebula astronomers are currently unsure how a star this huge could have formed or how it will act in the future.
A spectral nebula shining about five thousand light-years from Earth is also the coldest known object in the cosmos the dead star creating the boomerang nebula is sloughing off-gas from its shell which is producing the strangely shaped cosmic object astronomers have discovered the gas is cooling as it flows away from the white dwarf star in a process similar to how refrigerators stakeholding gas.
