NASA Keeping An Eye Out For Dangerous Asteroids

NASA has just received observations from its WISE (or Wide-field Infrared Survey Explorer) mission, giving them the best assessment thus far of how many PHAs (potentially hazardous asteroids) are floating around in our solar system. Now, the team at NASA can count these PHAs, discover their origins and predict what kind of harm they may pose to Earth. According to a report from NASA´s Jet Propulsion Laboratory in Pasadena, these PHAs are a subset of a larger group of near-Earth...

By University Of Arizona Communications The extraterrestrial rock is tumbling through space alongside thousands of similar objects in our solar system's main asteroid belt, roughly between the orbits of Mars and Jupiter. An asteroid discovered more than 100 years ago my not be an asteroid at all, but an extinct comet that is coming back to life, according to new observations. The night of Dec. 11, Steve Larson, senior staff scientist with the Catalina Sky Survey, was searching for potentially...

Scientists have discovered that a potentially hazardous asteroid might collide with Earth in 2182. The scientists used two mathematical models in order to determine the chance of impact. "The total impact probability of asteroid '(101955) 1999 RQ36' can be estimated in 0.00092 "“approximately one-in-a-thousand chance-, but what is most surprising is that over half of this chance (0.00054) corresponds to 2182," explains to SINC María Eugenia Sansaturio, co-author of...

Imagine you're a Brontosaurus with your face in a prehistoric tree top, munching on fresh leaves. Your relatives have ruled planet Earth for more than 150 million years. Huge and strong, you feel invincible. You're not. Fast forward about 65 million years. A creature much smaller and weaker dominates the Earth now, with brains instead of brawn. Its brain is a lot larger than yours relative to its body size "“ plenty big enough to conceive a way to scan the cosmos for objects like the...

You may want to thank David French in advance. Because, in the event that a comet or asteroid comes hurtling toward Earth, he may be the guy responsible for saving the entire planet. French, a doctoral candidate in aerospace engineering at North Carolina State University, has determined a way to effectively divert asteroids and other threatening objects from impacting Earth by attaching a long tether and ballast to the incoming object. By attaching the ballast, French explains, "you change...

Italian astronomer Andrea Boattini discovered six comets in 2008 while tracking cosmic debris throughout the solar system at Mount Lemmon Observatory in Arizona. And though it isn't a world record, the discovery of six comets in one year is the most found by an Italian astronomer since the mid-19th Century. The Catalina Sky Survey is part of a NASA project to find and track near-Earth objects (NEOs) using two telescopes in Arizona and one in Australia. In 1998, NASA started compiling an...

The University of Arizona's Catalina Sky Survey has been awarded a $3.16 million NASA grant to continue its search for near-Earth objects, or NEOs, through 2012.Under the direction of Stephen M. Larson of the UA's Lunar and Planetary Laboratory, the survey, known as CSS, has discovered about 70 percent of all NEOs found in past three years. CSS tallied 565 NEO discoveries in 2008, which broke its record-setting number of 460 NEO discoveries in 2007.Thanks to an additional $250,000 NASA grant,...
