NASA has detected a strange orbital movement of two Neptune moons

Life is not always easy for astrophysicists: just when they've discovered another aspect of the movement patterns in our solar system, two of the moons of Neptune come to mess things up. The two eligible moons are Naiad and Thalassa, both about 100 kilometers or 62 miles wide, and running around their planet in a race called "Dance of Avoidance" …

Planet Hunt Satellite Spots Rare hot Neptune

An artistic impression of a hot gas giant and its host star. SciNews.com Astronomers have used NASA's TESS data for planetary hunting to make an unusual discovery: a planet the size of Neptune, orbiting extremely close to its star. The planet TOI-132b has a orbital period of only 2.11 days and its surface temperature is estimated to be 1111 degrees …

Space Ballet: 2 Neptune Moons Perform an unusual Pas de Deux

The two innermost moons of Neptune are in an unusual "dance of avoidance", their perfect choreography ensuring that the moons never get too close. This is a difficult task since their orbits are only 1,850 kilometers apart. But the moons themselves never get closer than within 2,200 miles (3,450 kilometers) – a few hundred miles shorter than the width of …

Exomoon candidate in Neptune size may be the trapped core of a giant planet

The first serious Exomoon candidate is probably the captured core of a baby giant planet, when the exotic world actually exists, according to a new study. In October 2018, the Columbia University astronomers Alex Teachey and David Kipping announced that I had discovered evidence for a neptune-sized world orbiting Kepler-1625b a huge alien planet that had about 8,000 light-years is …

Neptune is a windy, cool and confusing planet. Let's go!

It was just after midnight at the mission control center of NASA's Jet Propulsion Laboratory, and Carl Sagan was left out. The Voyager 2 spacecraft had just completed its ten-year mission by coming closest to Neptune before setting off into interstellar space. It was the first – and so far only – spaceship to visit the mysterious blue giant ice …
