Amateur Astronomer Finds New Moon Orbiting Jupiter—10 Things You Need To Know

In addition to the four large Galilean moons, Jupiter has many smaller moons, up to a kilometer in size. Today, 79 of them are known, but there is no doubt that the giant planet has other small satellites that we have not yet noticed. One such was recently discovered by amateur astronomer Kai Ly, bringing the total to exactly eighty.

The Event Horizon Telescope has obtained the most detailed image of relativistic jets erupting from the core of the Centaurus A radio galaxy. It turned out that the structure of the jets closely resembles the jet in the active galaxy M87 on a scale of up to five hundred gravitational radii of a black hole.

Will GPS Work On The Moon? 10 Things You Need To Know

The American company Masten Space Systems will develop a lunar navigation system based on surface radio beacons. The device in lunar orbit will drop beacons to the surface that will be adapted for a hard landing and will be able to provide positioning for other satellites and spacecraft in lunar orbit, without the use of terrestrial navigation systems.

Jupiter’s Striking X-Ray Aurora Mystery Cracked By Experts—10 Things You Should Know

A team of researchers from University College London and the Chinese Academy of Sciences has tracked down the source of the bright X-rays that flash on Jupiter every few minutes. Thus, they unraveled the mystery of this phenomenon, the reasons for which remained unknown for the last 40 years. We finally understand Jupiter’s auroras.
