A collaboration between CalTech, Jet Propulsion Laboratory (JPL), University of Surrey, and the Indian Institute of Space Science and Technology (IIST) is developing the AAReST (Autonomous Assembly of a Reconfi
they can interact as the pull of their gravity potentially tips a world out of its originally upright position. Collisions can also change a planet's obliquity; scientists suspect that crashing objects may have turnedVenusandUranuson their axes. ...
Comets also influence planetary motion today. As Jupiter continues to fling comets outward, it moves inward ever so slightly because of the gravitational dance with the icy bodies. Neptune, meanwhile, throws comets inward and in turn gets a tiny outward push. Uranus and Saturn are also moving o...
NASA’sHubble Space Telescopehas allowed astronomers to view galaxies of all shapes and sizes from nearly every angle. When a galaxy is seen edge-on, the mesmerizing perspective reveals a dazzling slice of the universe. The “Little Sombrero,” also known as NGC 7814 or Caldwell 43, is one...
Small bodies are rocky and/or icy objects, usually ranging in size from a few meters to a few hundreds of kilometers. They comprise near-Earth and main belt asteroids, Jupiter Trojans, trans-Neptunian objects, Centaurs, comets, and a recently discovered category called the transitional objects....
“classical planets,”together with a number of dwarf planet.The classical planets are:Mercury; Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune.The debate over Plates status started in 1992.After an advanced telescope was sent into space, astronomers started to find a belt of objects,...
“We’ve confirmed three planets so far, and there are so many more that are just waiting for telescope and people time to be confirmed,” Dragomir says. “So it’s going really well, and TESS is already helping us to learn about the diversity of these small planets.” ...
