Top 10 Facts about Mysterious Object Oumuamua that We Force to Know

NASA scientists have conducted top 10 facts about the strange and mysterious object known as Oumuamua that we need knowing. This strange visitor is the first object ever seen in the solar system that is known to have originated elsewhere.  And NASA team has prepared 10 facts about Oumuamua that maybe we know or maybe we do not know which passes through our solar system.

Astronomers discovered Galaxy Rotate Once Every Billion Years

Astronomers Discovered Galaxies Rotate Once Every Billion Years

Astronomers have found out that all galaxies rotate once every billion years, there is no difference how big they are. For thousands of decades, people have measured the time by the movement of space. We know that a spin of the Earth is a day, an orbit of the moon is about a month and an orbit of the Earth around the Sun is a year. And according to this discovery we maybe change our calendars, because astronomers have discovered that all galaxies, no matter their size, rotate once every billion years. “It’s not Swiss watch precision,” Professor Gerhardt Meurer from the International center said in a statement.

Small Asteroid to shave Safely by Earth

The US space agency said “The space rock will shave safely by Earth at around 5:30 pm”. It will remain about 39,000 miles (64,000 kilometers) from Earth, which is less than one-fifth the distance to the Moon.“Asteroids of this size do not often approach this close to our planet — maybe only once or twice a year” : said Paul Chodas, manager of the Center for Near-Earth Object Studies at NASA’s Jet Propulsion Laboratory. According to the NASA an asteroid bigger than a city bus is on track to zoom by Earth Friday at a safe but close distance, less than one-fifth as far away as the Moon.  The asteroid is estimated to be between 50 and 130 feet (15 and 40 meters) in size.

Astronomical objects conjunction

Astronomical objects conjunction calendar for 2013

A conjunction occurs when two astronomical objects have either the same right ascension or the same ecliptical longitude, normally when observed from the Earth. In the case of two objects that always appear close to the ecliptic – such as two planets, or the Moon and a planet, or the Sun and a planet – this implies an apparent close approach between the objects as seen on the sky. In contrast, the term appulse is defined as the minimum apparent separation on the sky of two astronomical bodies.
Conjunctions therefore involve two Solar System bodies, or one Solar System body and one more distant object such as a star. A conjunction is an apparent phenomenon caused by perspective only: there is no close physical approach in space between the two objects involved. Conjunctions between two bright objects close to the ecliptic, such as two bright planets, can be easily seen with the naked eye and can attract some public interest.
