Kuiper belt: generalplanet-disk interactionszodiacal dustcircumstellar matterThe debris disk closest to Earth is the one around the star ϵ Eridani at a distance of 3.2 pc. It is the prime target for detailed studies of a belt of planetesimals left from the early phase of planet formation ...
In 2014, mission engineers tested its systems, nudged the small spacecraft into a better trajectory, and announced that it is on track to fly by Pluto one year from now, with the closest approach expected in mid-July 2015. Pluto is part of the Kuiper Belt, the outer ring of the solar...
Because Triton orbits the wrong way around Neptune, it is believed to have once been an object from the nearby Kuiper belt which was captured in the planet's orbit. "So it's a pretty cool to go and have a look at," said McCaughrean. As astronomers sweep the universe searching for ot...
These two images of Lake Superior and surrounding area show the first data downlinked from the CubeSat Multispectral Observation System (CUMULOS) cameras. The image on the left, taken by a short-wavelength infrared camera, captures a larger area of the lake and shows strong contrast between land...
Afterwards, the ordinary and extraordinary image in each exposure was cut out and all images of each filter (i.e., all dither po- sitions, all ... Sascha,P.,Quanz,... - 《Astrophysical Journal》 被引量: 74发表: 2011年 Herschel images of Fomalhaut. An extrasolar Kuiper Belt at the ...
The planets are 24, 37 and 67 times the Earth-sun separation from the host star. The furthest planet in the new system orbits just inside a disk of dusty debris, similar to that produced by the comets of the Kuiper belt of our solar system (just beyond the orbit of Neptune at 30 tim...
The placid appearance of the Sun's surface belies a hot fireball of plasma in constant turmoil. A granular network invisible to the naked eye pervades the solar disc, with cells of hotter and colder plasma popping up, merging and disappearing within only
NASA and the European Space Agency's (ESA) Solar Orbiter spacecraft ismaking a beeline for the sun. On the way there, it's managed to snap some incredible photos. Today, the space agencies have announced that Solar Orbiter has taken the closest ever-image of the sun. The stunning photo...
NASA's historic Parker Solar Probe mission will revolutionize our understanding of the Sun, where changing conditions can propagate out into the solar system, affecting Earth and other worlds. Parker Solar Probe will travel through the sun's atmosphere, closer to the surface than any spacecraft be...
