Rescuers are still digging through the rubble and debris after a monster tornado roared through Moore, Oklahoma yesterday. Spectacular video is surfacing of the tornado that leveled neighborhoods, schools and more.
How Does a Tornado Form?
Tornadoes need two things to form – a thunderstorm and wind shear. Wind shear is created from winds blowing in different directions and increasing with height. The winds are at two different altitudes and blow at two different speeds. For example, a wind at 1,000 feet above the surface blows at 10 mph and one at 5,000 feet blows at 25 mph. This creates an invisible column of horizontal air that is rotating. The rotating air will be drawn into the thunderstorm cloud by the updraft which tilts the air. If the column gets caught in the supercell updraft, the spin
On Sunday, May 26th, a very special sunset will take place. Three planets – Venus, Jupiter and Mercury will form a triangle in the night sky. They will all be visible to the naked eye or seen together in a binocular field.
This is a fairly rare celestial event. The last time it happened was in May 2011 and the next time the planets will form a geometric shape will be in October 2015.
The three planets are the brightest in the sky. Venus is #1, followed by Jupiter #2 and Mercury #3. Their triangle will be visible even in urban areas with lots of lights.
To find the trio, look about 30 to 60 minutes after sunset at the western horizon. Venus will be the brightest and lowest with Mercury to the right

A video of Duncanville High School student Jeff Bliss has gone viral after a classmate recorded his rant in the classroom last week. Bliss is an 18-year-old sophomore who returned to 10th grade after dropping out. He says he realized the importance of an education for his future. He now takes his education and the learning of others very seriously.
Bliss had questioned why the teacher didn’t give the students more time to prepare for a test. She asked him to leave the classroom and he began sharing his opinions of why students were not reaching their true potential. He claimed the teacher only passed out worksheets and packets instead of creating lively and engaging discussions.
In Bliss’ opinion, the classroom time was a waste and challenged the teacher to get the students excited about learning. He also felt teachers must reach out and touch the hearts of their students to truly engage them.
“Just as much as the students need to give an effort, the teachers need to give an effort too.” said Jeff Bliss.
