Brett Smith for redOrbit.com - Your Universe Online An investigation of Vesta, a massive asteroid that orbits the Sun between Mars and Jupiter, has revealed that the planet-like body has a thicker crust than previously thought, which calls into question the internal structures of other planets in the Solar System. The investigation, which is published in the journal Nature, is based on data from the Dawn spacecraft that NASA sent into Vesta's orbit between July 2011 and July 2012. Using...

Preston Dyches, NASA Jet Propulsion Laboratory Twenty years ago, human and robotic eyes observed the first recorded impact between cosmic bodies in the solar system, as fragments of comet Shoemaker-Levy 9 slammed into the atmosphere of Jupiter. Between July 16 and July 22, 1994, space- and Earth-based assets managed by NASA's Jet Propulsion Laboratory in Pasadena, California, joined an armada of other NASA and international telescopes, straining to get a glimpse of the historic event: -...

New Evidence Suggests Mercury Was Formed From A Stellar Collision
2014-07-08 10:50:50

Gerard LeBlond for redOrbit.com - Your Universe Online Planet Mercury has an unusual metal-rich composition which has baffled the scientific community. However, new evidence may have solved this mystery. According to a new study published online in Nature Geoscience on July 6, Mercury along with other space objects in the solar system with an unusual metal-rich composition, may be left over from stellar hit-and-run collisions in the early formation of the solar system. The...

Computing Asteroid Paths For Future Exploratory, Redirect Missions

Gerard LeBlond for redorbit.com - Your Universe Online Asteroids are chunks of debris left over from the solar system’s formation. They are a substantial interest to scientists, having possible resources embedded within them. Water, along with other resources found on these asteroids would be a benefit to astronauts traveling into deep space with missions to Mars and even deeper in our solar system. Currently, NASA is developing methods needed for a 2030s mission to Mars. In the...

Citizen Scientists Can Now Help Discover NEAs Using Asteroid Zoo
2014-06-25 09:09:37

Gerard LeBlond for redorbit.com - Your Universe Online Near-Earth Asteroids (NEAs) are space rocks that will pass close by our planet with a potential risk of impact. NASA, astronomers and scientists search the sky continually for these types of asteroids. Now, with the launch of Asteroid Zoo, the general public can assist in the search for undiscovered NEAs. Asteroid Zoo was launched on June 24, 2014 by Planetary Resources and Zooniverse allowing the general public, citizen scientists...

Asteroid Grand Challenge First Anniversary
2014-06-20 03:13:27

NASA It’s been a busy year around the sun for NASA’s Asteroid Grand Challenge. NASA has been active in learning new ways to find, track and characterize asteroids and thinking about ways to respond to asteroid threats to human population. If you want to help, there are lots of opportunities, including a virtual workshop in celebration of the first anniversary of the public announcement of NASA’s Asteroid Grand Challenge on June 19-20. On June 18, 2013, NASA announced the Asteroid...

WASHINGTON, June 19, 2014 /PRNewswire-USNewswire/ -- NASA is on the hunt for an asteroid to capture with a robotic spacecraft, redirect to a stable orbit around the moon, and send astronauts to study in the 2020s -- all on the agency's human Path to Mars. Agency officials announced on Thursday recent progress to identify candidate asteroids for its Asteroid Redirect Mission (ARM), increase public participation in the search for asteroids, and advance the mission's design....

Asteroid 2014 HQ124

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...

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
2012-10-22 06:09:41

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...

Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
