Asteroid 2014 HQ124
2014-06-13 11:15:52

Gerard LeBlond for redOrbit.com - Your Universe Online An asteroid, designated “2014 HQ124” at least 1,200 feet wide on its long axis, passed by Earth on June 8, 2014. It came within 776,000 miles, or approximately three times the distance to the moon. Images captured of the asteroid are some of the most detailed in NASA’s history. The asteroid was first spotted on April 23, 2014 by NASA’s NEOWISE mission. NEOWISE was adapted for capturing infrared light emitted from comets and...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Despite being the nearest astronomical object to Earth, and the only extraterrestrial site of human visitors, the Moon still contains mysteries that have puzzled scientists for the better part of a century. Perhaps the greatest question surrounding lunar history is its two-faced nature. Due to the mutual gravitational interaction of the Earth-Moon system, the giant satellite is tidally locked with our planet, so we always see...

Brett Smith for redOrbit.com - Your Universe Online Last year, a massive asteroid that had gone undetected exploded over Chelyabinsk, Russia in a huge fireball and another, much bigger asteroid spotted in April is expected to buzz past Earth this weekend. While the incoming HQ124 asteroid, aka “the Beast,” is not expected to make contact with the Earth’s atmosphere, professional skywatchers will be keeping close tabs on the massive space rock nonetheless. “What’s...

Sentinel Telescope May Help Save Us From Earth-Killing Asteroids

Lawrence LeBlond for redOrbit.com - Your Universe Online Asteroid impacts on Earth – those on the scale of the one that wiped out the dinosaurs 65 million years ago – have been big hits in Hollywood. But in the modern world, are the impacts portrayed in movies like Deep Impact and Armageddon only the stuff of science fiction? The answer is likely no. Scientists continue to warn us of the dangers that lurk in the skies above us and in the past dozen or so years, no less than 26...

asteroid impact

Brett Smith for redOrbit.com - Your Universe Online Earth was irrevocably changed when the dinosaurs were wiped out about 65 million years ago by a massive asteroid, but a much bigger asteroid that struck the Earth nearly 3.3 billion years ago is thought to have shaped parts of Africa. Now, a new study published in the journal Geochemistry, Geophysics, Geosystems has outlined the details surrounding that massive impact, such as the creation of a crater about 300 miles across and...

Small Asteroid Regolith Formed By Thermal Fatigue
2014-04-04 06:21:44

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Small asteroids contain a layer of loose, unconsolidated rock and dust known as a regolith composed of centimeter-sized fragments and smaller particles. New research from researchers at the Observatoire de la Côte d'Azur, Hopkins Extreme Materials Institute at Johns Hopkins University, Institut Supérieur de l'Aéronautique et de l'Espace and Southwest Research Institute (SwRI), have now determined that this layer is formed by...

Citizen Scientists Wanted To Observe Asteroid Blot Out A Star
2014-03-17 08:49:55

Lawrence LeBlond for redOrbit.com - Your Universe Online Millions of Americans may be able to catch a space rock darkening the night sky this Thursday as the brightest visible star vanishes before our very eyes. If you live in the Northeast and the skies are clear, you may want to go out and look up at around 2 a.m (EDT) on March 20. If by chance the skies are clear, then you will want to look to the western skies toward the constellation Leo and hunt down the bright star known as...

Asteroid Hunting Contest Offers $35,000 To Citizen Scientists

WASHINGTON, March 6, 2014 /PRNewswire-USNewswire/ -- NASA's Hubble Space Telescope has recorded the never-before-seen break-up of an asteroid into as many as 10 smaller pieces. http://photos.prnewswire.com/prnvar/20081007/38461LOGO Fragile comets, comprised of ice and dust, have been seen falling apart as they near the sun, but nothing like this has ever before been observed in the asteroid belt. "This is a rock, and seeing it fall apart before our eyes is pretty amazing," said...

Johann Daniel Titius was born on January 2, 1729 in Konitz, Royal Prussia. He was a professor at Wittenberg. He is most famous for the Titius-Bode law, which helped him find the existence of a minor planet at 2.8 AU from the sun in 1766. The planet was later named Ceres. Titius died in Wittenberg on December 11, 1796. To his honor, the Titius asteroid in 1998 and the Titius lunar crater are named after him.

Lagrangian Point -- In Lagrangian mechanics, a Lagrangian point (or L-point) is one of five positions in space where the gravitational fields of two bodies of substantial but differing mass combine to form a point at which a third body of negligible mass would be stationary relative to the two bodies. Bodies at the L-point will not move relative to the parent bodies if they are not perturbed by other gravitational forces. They are sometimes also referred to as libration points. The...

Planet -- A planet is a body of considerable mass that orbits a star and that doesn't produce energy through nuclear fusion. Until recently, only nine were known (all of them in our own Solar system). As of the end of 2002 over 100 are known, with all of the new discoveries being extrasolar planets. Astronomers often call asteroids minor planets, and call the larger planetary bodies (those which are commonly called planets) major planets. Planets within the solar system can be...

Asteroid -- An asteroid, also called a minor planet or planetoid, is a member of a group of small, planet-like bodies that are part of our solar system. They are believed to be remnants of the interstellar clouds, nebula, that were not incorporated into planets during the formation of the solar system. The largest asteroid in the inner solar system is Ceres with a diameter of 1003 km. It also was the first to be discovered, by Giuseppe Piazzi on January 1, 1801. Nowadays, over 9000...

Solar System

The Solar System refers to the area in space that is dominated by our own Sun. It is comprised of the Sun and its associated astronomical objects that are held in its gravitational orbit. The Solar System was formed as a result of the collapse of a giant molecular cloud approximately 4.6 billion years ago. The mass of this system is located almost entirely in the Sun. Apart from the Sun, a high percentage of the remainder of the system’s mass is located in the eight solitary planets that...
