2002 AJ129 is an intermediate-sized near-Earth asteroid, somewhere between 0.3 miles (0.5 kilometers) and 0.75 miles (1.2 kilometers) across. It was discovered on January 15th, 2002, by the former NASA-sponsored Near Earth Asteroid Tracking project at the Maui Space Surveillance Site on Haleakala, Hawaii. ![]() Asteroid 2002 AJ129 will make a close approach to Earth on Feb. 4, 2018, at 1:30pm PST (3:30pm CST). At the time of closest approach, the asteroid will be at a distance of 2.6 million miles, or 4.2 million kilometers — about 10 times the distance between Earth and the moon. «Read the rest of this article» Sections: News | No Comments
NASA tracks Asteroid/Comet that recently appeared in our Solar SystemWritten by DC Agle
This unusual object – for now designated A/2017 U1 – is less than a quarter-mile (400 meters) in diameter and is moving remarkably fast. Astronomers are urgently working to point telescopes around the world and in space at this notable object. Once these data are obtained and analyzed, astronomers may know more about the origin and possibly composition of the object. ![]() This photon shows the path of A/2017 U1, which is an asteroid — or perhaps a comet — as it passed through our inner solar system in September and October 2017. From analysis of its motion, scientists calculate that it probably originated from outside of our solar system. (NASA/JPL-Caltech) «Read the rest of this article» Sections: Technology | No Comments
NASA reports small Asteroid to pass close but safely past EarthWritten by DC Agle
This encounter with TC4 is being used by asteroid trackers around the world to test their ability to operate as a coordinated international asteroid warning network. 2012 TC4 is estimated to be 50 to 100 feet (15 to 30 meters) in size. Orbit prediction experts say the asteroid poses no risk of impact with Earth. ![]() This image depicts the safe flyby of small asteroid 2012 TC4 as it passes under Earth on Oct. 12, 2017. While scientists cannot yet predict exactly how close the 50 to 100 foot (15 to 30 meter) wide space rock will approach, they are certain it will come no closer than 4,200 miles (6,800 kilometers) from Earth’s surface.

NASA’s Juno mission observes Jupiter’s Auroras acting differently than expectedWritten by DC Agle
Examining data collected by the ultraviolet spectrograph and energetic-particle detector instruments aboard the Jupiter-orbiting Juno spacecraft, a team led by Barry Mauk of the Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland, observed signatures of powerful electric potentials, aligned with Jupiter’s magnetic field, that accelerate electrons toward the Jovian atmosphere at energies up to 400,000 electron volts. ![]() This is a reconstructed view of Jupiter’s northern lights through the filters of the Juno Ultraviolet Imaging Spectrograph instrument on Dec. 11, 2016, as the Juno spacecraft approached Jupiter, passed over its poles, and plunged towards the equator.

NASA’s Juno Spacecraft to make Seventh Pass over JupiterWritten by DC Agle
At the time of perijove (defined as the point in Juno’s orbit when it is closest to the planet’s center), the spacecraft will be about 2,200 miles (3,500 kilometers) above the planet’s cloud tops. Juno launched on August 5th, 2011, from Cape Canaveral, Florida, and arrived in orbit around Jupiter on July 4th, 2016. During its mission of exploration, Juno soars low over the planet’s cloud tops — as close as about 2,100 miles (3,400 kilometers). ![]() Citizen scientist David Englund created this avant-garde Jovian artwork using data from the JunoCam imager on NASA’s Juno spacecraft.

NASA’s Juno Spacecraft gets close up look at Jupiter’s Great Red SpotWritten by DC Agle
The images of the Great Red Spot were downlinked from the spacecraft’s memory on Tuesday and placed on the mission’s JunoCam website Wednesday morning. ![]() This enhanced-color image of Jupiter’s Great Red Spot was created by citizen scientist Jason Major using data from the JunoCam imager on NASA’s Juno spacecraft.

NASA’s Juno Spacecraft Completes Flyby over Jupiter’s Great Red SpotWritten by DC Agle
All of Juno’s science instruments and the spacecraft’s JunoCam were operating during the flyby, collecting data that are now being returned to Earth. Juno’s next close flyby of Jupiter will occur on September 1st, 2017. Raw images from the spacecraft’s latest flyby will be posted in coming days. ![]() This illustration depicts NASA’s Juno spacecraft in orbit above Jupiter’s Great Red Spot.

NASA’s Juno Spacecraft to take close up look at Jupiter’s Great Red SpotWritten by DC Agle / Guy Webster
“Jupiter’s mysterious Great Red Spot is probably the best-known feature of Jupiter,” said Scott Bolton, principal investigator of Juno from the Southwest Research Institute in San Antonio. “This monumental storm has raged on the solar system’s biggest planet for centuries. Now, Juno and her cloud-penetrating science instruments will dive in to see how deep the roots of this storm go, and help us understand how this giant storm works and what makes it so special.” ![]() This true color mosaic of Jupiter was constructed from images taken by the narrow angle camera onboard NASA’s Cassini spacecraft on December 29, 2000, during its closest approach to the giant planet at a distance of approximately 10 million kilometers (6.2 million miles).

NASA’s Near-Earth Object Wide-field Infrared Survey Explorer continues finding unknown objectsWritten by DC Agle
The spacecraft has now characterized a total of 693 near-Earth objects since the mission was re-started in December 2013. Of these, 114 are new. The NEOWISE team has released an animation depicting this solar system survey’s discoveries and characterizations for its third year of operations. ![]() This image shows the progression of NASA’s Near-Earth Object Wide-field Survey Explorer (NEOWISE) investigation for the mission’s first three years following its restart in December 2013.

NASA’s Juno Spacecraft provides fascinating discoveries about JupiterWritten by DC Agle
“We are excited to share these early discoveries, which help us better understand what makes Jupiter so fascinating,” said Diane Brown, Juno program executive at NASA Headquarters in Washington. “It was a long trip to get to Jupiter, but these first results already demonstrate it was well worth the journey.” ![]() NASA’s Juno spacecraft carries an instrument called the Microwave Radiometer, which examines Jupiter’s atmosphere beneath the planet’s cloud tops.
