A new dwarf planet lurking beyond Neptune and Pluto has just been declared a part of our solar system. The dwarf planet called 2014 UZ224, is about 330 miles across and is located some 8.5 billion miles from the Sun. The planet is so small that scientists are currently unsure whether it could retain the status as a dwarf planet in future, but for now, it falls in the same category as Makemake, Sedna, Eris and, of course, Pluto like dwarf planets.
It takes more than 1000 years to complete an orbit around Sun and is believed to be the third most-distant object in the solar system.
Moon, our closest neighbor in outer space, is more violent and active place than we previously thought. Using cameras onboard NASA’s Lunar Reconnaissance Orbiter, researchers have identified more than 200 new craters on moon's surface, meaning they are formed relatively recently.
The craters vary in size ranging from small to 140 feet large. Scientists believe that these craters on the moon’s surface are caused by the falling space rocks, which creates splotches every time they hit the surface of the moon. Based on these observations, the researchers estimate that the moon’s uppermost surface material gets a full makeover every 81,000 years or so, which is more than 100 times faster than previous estimates.
A new analysis of the data from Hubble Space Telescope reveals that universe contains 2 trillion galaxies – 10 times more than was previously thought.
Counting all the galaxies in the universe is extremely difficult and there is only one way we have so far: direct a telescope at a small patch of sky, tally up the number of galaxies you see and then take it as a standard across the whole sky. But now researchers suggest that the universe looks a lot more crowded, thanks to the data provided by Hubble Space Telescope and other observatories. Universe has many galaxies that are too faint and too far away to be observed even with the most powerful telescopes in the world.
Researchers working in African country Tanzania have found a treasure of ancient human footprints. The footprints were left by ancient people between 5,000 and 19,000 years ago while they were walking across the muddy terrain along the southern shore of Tanzania’s Lake Natron. These footprints give researchers a unique opportunity to understand the story of earliest humans. However, they are not the oldest to be discovered.
A group of researchers has recently revealed the plans of what they call the first nation in outer space. The proposed space nation has been named Asgardia after the mythological city ruled by the Norse god Odin and is introduced by a Russian scientist named Dr. Igor Ashurbeyli, who is also the founder of Vienna's Aerospace International Research Center.

Asgardia will be a permanent space station where human will live, work and socialize as they do on Earth. The initial satellite is expected to be launched next year coincided with the 60th anniversary of the launch of Russia’s Sputnik satellite.
