The Most Well Preserved Dinosaur Fossil Ever Unveiled in Canada

The world’s best preserved dinosaur fossil which was discovered in Canada six years ago finally went on display at Royal Tyrrell Museum of Palaeontology on Friday.

The dinosaur fossil is 18 foot long and weighs around 3,000 pound. It is a new species of nodosaur, an armored, plant-eating dinosaur that lived in western Canada some 110 million years ago. Considering the dinosaur fossil is millions of years old, it is in a remarkably great condition. Its skin is still intact and is covering armor plates of the animal’s body. The fossil is so well preserved that it does not look real. It could be easily mistaken by a life-size sculpture of a dinosaur.

NASA Satellite Spots Unusual Flashes of Light on Earth

A NASA camera has caught hundreds of strange flashes of light in Earth’s atmosphere over the span of a year. These flashes were recently noticed by a NASA scientist as he was looking through the images taken by the camera.

When NASA researchers started probe into the issue, they found that similar reflections were also observed back in 1993. But researchers could not explain the phenomenon at that time. Now they believe that these flashes are reflected by sunlight and are coming from ice crystals located high in the Earth atmosphere. The flashes are limited to certain locations on Earth and observable at specific angle from space.

Indian Teen Built World’s Lightest Satellite in NASA Competition

An 18-year old Indian student has developed what is believed to be the smallest and lightest satellite in the world. The satellite weighs just 64 grams and will be sent into space by NASA next month.

Named KalamSat, the satellite was selected through a competition called “Cubes in Space.” As its name suggests, the competition is based on design structures that must fit into a 40 mm cube. Indian teen Rifath Sharook’s structure is made of 3D printed carbon fiber and is even lighter than a smartphone. The satellite will be launched from a NASA facility on June 21 and will be tested for few minutes under microgravity conditions in space.

Dinosaurs may have Survived if Asteroid Hit Minutes Later

The asteroid that killed dinosaur would have caused less damage if it had struck Earth 30 seconds later or 30 seconds sooner, researchers claim.

The asteroid was estimated to be nine miles across and it was travelling at 40,000mph. If it had arrived a few seconds sooner or later, it could have landed in the waters off Atlantic or Pacific ocean and vaporized instantly. Instead, the asteroid hit the worst possible place, the Earth. The impact of the asteroid threw enough dust into the air that it blocked the sunlight across the globe for many years. As a result, the planet turned dark and cold and the event led to the extinction of many species.

A New Moon Discovered around Third Largest Dwarf Planet

The third largest dwarf planet in our solar system has its own moon. Using the combined power of three space observatories, including archival images from the Hubble Space Telescope, astronomers have uncovered a moon orbiting dwarf planet 2007 OR10. The dwarf planet is about 950 miles across and lies in Kuiper Belt beyond the orbit of Neptune. The discovery can provide insight into how moons formed in the young solar system billions of years ago.
