Retrograde motion, typically observed in outer planets, is an apparent westward movement resulting from Earth's faster orbital speed overtaking those planets. This apparent reversal of direction is ...

There are a lot of moving parts to the Universe, as nothing exists in isolation. There are literally trillions of large masses in our Solar System, all orbiting around the galactic center on ...

Since 2004, I have worked on PCMag’s hardware team, covering at various times printers, scanners, projectors, storage, and monitors. I currently focus my testing efforts on 3D printers, pro and ...

From an early age, we are taught to understand that the planets of our solar system change in position while orbiting a central star, the sun. But does the sun itself move within the solar system?

They’re hot, they’re huge and they move the wrong way. In the rapidly growing catalog of planets found outside the solar system, about a dozen Jupiter-sized ones tightly circle their stars in the ...

ALMA observations of the spiral patterns in the disk around the young star IM Lup. The Atacama Large Millimeter/submillimeter Array (ALMA) has captured the motion of spirals of dust around a young ...

In this work, we extensively investigate the formation of near 4:2:1 mean motion resonances (MMRs) configuration by performing two sets of N-body simulations. We model the eccentricity damping, gas ...

The Atacama Large Millimeter/submillimeter Array (ALMA) has captured the motion of spirals of dust around a young star and shown that the winding motion of the spiral pattern is conducive to planet ...
