"Some of the more than 200 pits leading to the tunnels are apparently collapsed lava tubes," said the lead researcher. In a study in the journal Geophysical Research Letters. According to him, a stable temperature of about 17 degrees Celsius will allow protection against the extreme changes between day and night. The caves will also provide partial protection from radiation

Jupiter was discovered to be inhomogeneous - the metallicity reveals new clues about the origin of the planet

  • 4 תגובות
An international team of astronomers found that the gaseous mantle of Jupiter does not have a homogeneous distribution. The inner part has more metals than the outer parts, and they amount to 11 to 30 Earth masses and constitute 3-9% of the total mass of Jupiter. It is likely that these are Jupiter's planets and moons. Bela" at the time of its formation

Astronomers rarely use their telescopes just to take pictures. The images in astrophysics are usually created by a process of scientific inference and imagination, the visual expression of which is sometimes an artist's impression of what emerges from the data but there are also some gems that are photographed directly
