Asteroid passing close to Earth soon!

Asteroid passing close to Earth soon!

Nov 17

Space rock, 2001 AV43, will pass within 650,000 miles of Earth on Monday.  This is only 2.7 times the distance from Earth to the moon.  A cosmic eyelash.  It is between 100-230 feet in diameter and has a velocity of 8,000 mph.  This is the same size as the meteor crater in Arizona created 50,000 years ago.  That meteor was 165 feet in diameter and had the force of 10 megatons of TNT! Asteroids are large rock in outer space. Some can be very large, while others are as tiny as a grain of sand. With their smaller size, asteroids do not have enough gravity to pull themselves into the shape of a ball.  Asteroids are left over materials from the formation of the Solar System.  26 very large asteroids have been discovered, which are probably the bigger ones. There are millions of smaller ones that we have yet to discover since they are too tiny, only a mile or so across. Scientists are also tracking two other near Earth asteroids.  2013 UD4 was spotted from Arizona when it was 230 million miles from Earth.  2013 UP8, discovered by scientists on the Big Island of Hawaii on Haleakala,  is 3.4 million miles from Earth. Scientist don’t see any of these asteroids as foreseeable hazards to Earth.  Of these asteroids, only 2013 UP8 is considered “potentially hazardous” to Earth.  Don’t worry, comets and asteroids only hit the Earth every 100 million years or so!...

Earth’s Twin from Hell!

Earth’s Twin from Hell!

Oct 31

Kepler-78b is a planet 400 light years away.  However it is Earth’s hellish twin!  Astronomers describe it as the first Earth sized planet made of the same rock and iron as Earth.  It also orbits a star similar to our sun. But we won’t want to be visiting Kepler-78b anytime soon!  Kepler-78b whirls around its parent star in 8 1/2 hours!  Remember Earth orbits the sun in 365 days!  At that proximity, it’s a hellishly hot place to be.  Scientists estimate that its 3,500-5,000 degrees F.  At that temperature, rock will melt! Kepler-78b’s mass is estimated at 1.69 times that of Earth. Astronomers feel that this discover is an “encouraging sign” in the search for new  habitable worlds beyond our Solar System. Astronomers using the Kepler telescope said the Milky Way contained at least 17 billion planets the size of Earth, and likely many...

Sun’s Magnetic Flip Coming!

Sun’s Magnetic Flip Coming!

Aug 08

Scientists say that the sun will undergo a magnetic flip in the next couple of months.  This happens once every eleven years and will have effects throughout the solar system.  The sun’s polar magnetic field weakens and will reverse.  The sun’s north pole will go from negative to positive and the sun’s south pole will switch from positive to negative. NASA observatories indicate that the flip will happen in the next 3-4 months.  In fact, the north pole has already flipped!  What happens when it flips?  The sun’s sheet which is a massive surface 10,000 km thick and billions wide will become wavy.  This wavy sheet will create cosmic stormy weather throughout the solar system.  It will also deflect cosmic rays and protect astronauts and shuttles from space particles.
