April Flowers for redOrbit.com - Your Universe Online When it came to jump-starting life, the early Earth was not a very hospitable place. New research from the Lawrence Livermore National Laboratory (LLNL) and the University of Ontario Institute of Technology (UOIT) reveals that life on Earth may indeed have come from outer space. LLNL scientist Nir Goldman and UOIT´s Isaac Tamblyn — a former LLNL postdoctoral researcher — found that billions of years ago icy comets...

Astronomers Discover Asteroid Has Much Longer Tail Than Thought
2013-06-03 10:06:31

Brett Smith for redOrbit.com - Your Universe Online Using the new wide-field camera at the WIYN Observatory´s 3.5-meter telescope, astronomers at the facility have discovered that asteroid P/2010 A2's recently-formed tail is much longer than previously believed. The astronomers said the tail is about 620,000 miles long, or about triple the distance from the Earth to the Moon. The scientists were able to see the complete tail using the new One Degree Imager (ODI) -- a wide-field...

Asteroid Makes Safe Fly-By Of Earth
2013-06-01 06:44:29

redOrbit Staff & Wire Reports - Your Universe Online Asteroid 1998 QE2 and its recently discovered moon sailed safely past the Earth on Friday, passing within 3.6 million miles of our planet at approximately 5pm Eastern time, according to various media reports. During its fly-by, QE2 was 200 times further away from the Earth than an asteroid “near-miss” which took place back in February, according to BBC News. However, it was over 50,000 times larger than that object,...

Comet ISON On Uncertain Course Towards The Sun
2013-05-31 04:32:24

April Flowers for redOrbit.com - Your Universe Online Comet C/2012 S1 (ISON) is racing toward an uncomfortably close rendezvous with the Sun, according to a new series of images from the Gemini Earth Observatory. Comet ISON might present a stunning sight in the twilight sky of late November that will remain easily visible, even brilliant, into early December. Gemini´s time-sequence images span from early February through May 2013, showing the comet´s remarkable activity...

NASA Traces Evolution Of Asteroid Families
2013-05-30 11:54:27

Brett Smith for redOrbit.com - Your Universe Online Using the orbiting Wide-field Infrared Survey Explorer (WISE), NASA scientists have been able to identify and categorize 28 new asteroid families found in the main belt between Mars and Jupiter, the space agency announced. Infrared snapshots from the asteroid-hunting section of the survey, called NEOWISE, allowed scientists to spot and sort thousands of previously hidden and uncategorized asteroids into families. "NEOWISE has given...

Planetary Resources To Announce Unprecedented Project On May 29th
2013-05-29 12:40:36

UPDATED : 12:30 CDT Lee Rannals for redOrbit.com - Your Universe Online The company best known for its ambitious goal to mine asteroids announced an “unprecedented project” on Wednesday. Planetary Resources said it would be launching the world's first crowdfunded space telescope to provide "unprecedented public access to space." It added that this telescope will allow students and scientists access to the most advanced exploration technology. The company will be using...

John P. Millis, Ph.D. for redOrbit.com — Your Universe Online The potential of a human mission to Mars has captured the imagination of many recently. However, before astronauts set foot on the Red Planet, NASA first plans to visit Near-Earth asteroids and potentially to the moons of Mars. With this vision in mind, a team of researchers from the SETI Institute, the Mars Institute, NASA Ames Research Center, and the space robotics company Honeybee Robotics successfully completed a...

NASA Moving Forward With Plans To Sample Asteroids
2013-05-17 05:49:00

[WATCH VIDEO: OSIRIS-REx To Investigate Asteroid Bennu] Lee Rannals for redOrbit.com — Your Universe Online NASA said it is moving forward with its plan to send a spacecraft to an asteroid to bring back a sample to Earth. The space agency's Origins-Spectral Interpretation Resource Identification Security Regolith Explorer (OSIRIS-REx) mission to sample asteroid Bennu is moving ahead in preparation for its launch in 2016. After launch, OSIRIS-REx will rendezvous with the...

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...
