Hypervelocity Stars Escape Galaxy
2014-01-10 08:44:12

April Flowers for redOrbit.com - Your Universe Online A surprising new class of hypervelocity stars has been discovered by an international team of astronomers. These solitary stars are moving fast enough to escape the gravitational grasp of the Milky Way galaxy, according to a study presented at the annual meeting of the American Astronomical Society. The findings were also published in the Astrophysical Journal. "These new hypervelocity stars are very different from the ones that...

Protecting Spacecraft From Space Junk

Lee Rannals for redOrbit.com - Your Universe Online Researchers developed a numerical algorithm that simulates the shock of orbital debris striking materials that make up a space vehicle's outer defense. Scientists commonly use supercomputers to investigate physical phenomenon that cannot be duplicated in a laboratory environment. By running simulations on these such computers, University of Texas researchers have assisted NASA in the development of ballistic limit curves that predict...

Targeting An Asteroid

NASA's Jet Propulsion Laboratory Like many of his colleagues at NASA's Jet Propulsion Laboratory, Pasadena, Calif., Shyam Bhaskaran is working a lot with asteroids these days. And also like many of his colleagues, the deep space navigator devotes a great deal of time to crafting, and contemplating, computer-generated 3-D models of these intriguing nomads of the solar system. But while many of his coworkers are calculating asteroids' past, present and future locations in the cosmos,...

How To Remove Orbital Debris With Less Risk
2013-03-22 20:53:40

Lee Rannals for redOrbit.com — Your Universe Online An article coming out in the Journal of Spacecraft and Rockets pitches ideas to attempt to remove orbital debris with less risk. The article, authored by Kerry Nock and Dr. Kim Aaron, of Global Aerospace Corporation (GAC), and Dr. Darren McKnight, of Integrity Applications Incorporated, Chantilly, VA, compared in-orbit debris removal options regarding their potential risk of creating new orbital debris or disabling working...

Asteroid Mission Targets Didymos In 2022
2013-02-23 05:53:38

redOrbit Staff & Wire Reports - Your Universe Online In the wake of the recent meteor explosion above Russia, the European Space Agency (ESA) has announced the selection of a target for their proposed Asteroid Impact and Deflection Assessment (AIDA). The AIDA mission, which is a joint project headed up by European and American astronomers, will attempt to intercept asteroid Didymos, which the ESA says is a “binary,” featuring two asteroids — one approximately 800...

Idan Ginsburg, a graduate student in Dartmouth's Department of Physics and Astronomy, studies some of the fastest moving objects in the cosmos. When stars and their orbiting plants wander too close to the supermassive black hole at the center of the Milky Way, their encounter with the black hole's gravitational force can either capture them or eject them from the galaxy, like a slingshot, at millions of miles per hour. Although their origin remains a mystery and although they are...

Runaway Planets At 30 Million Miles Per Hour Possible
2012-03-22 13:27:20

Harvard-Smithsonian Center for Astrophysics researchers have determined that some planets are flying around in space at 30 million miles per hour. These hypervelocity planets are produced in the same way as the hypervelocity star that was found seven years ago traveling around the Milky Way Galaxy at 1.5 million miles per hour. "These warp-speed planets would be some of the fastest objects in our Galaxy," astrophysicist Avi Loeb of the Harvard-Smithsonian Center for Astrophysics said in...

Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
