The thermal effect of the Enceladus moon and the Taurid meteorite shower.

Researchers found a new heat source in Saturn’s icy moon Enceladus. That heat can form in water flows on that icy moon. Low gravity and a quite close distance to the giant planet Saturn can cause whirls in that moon’s water layers. That means tidal forces can keep the ocean under Enceladus’ icy shell in liquid form. On that moon, tidal forces have a much stronger effect than on Earth. 

The moon’s low gravity means that water can stay liquid at much lower temperatures than on Earth.  The low gravity on Enceladus keeps water molecules at a greater distance. From each other. There are models that suggest Enceladus could be a harbour. For some kind of lifeforms. There could be living organisms in that water. The heat source on that distant moon can be friction in that icy water.

Meteorite showers are one of the things that should worry people. 

Meteorite showers form when large groups of small meteorites fall into the Earth's atmosphere. If those meteorites involve lots of iron, they travel to the poles. And that forms a beautiful sight. But the problem is that. Those meteorites or meteoroids can hit satellites. That thing can cause a situation. Where a large number of satellites will be broken. When a meteoroid hits the satellite, it has the same effect as bullets.

The difference between a meteoroid and a meteorite is that a meteoroid is a small meteorite that burns in the atmosphere. The stone that hits the ground is called a meteorite. Meteorite showers can cover the space from the ground-based observations. That causes a situation. Where meteorite showers can harm deep-sky surveillance. But. Their biggest problem is that those meteoroids can form an ionized gas layer, which causes problems for radar-based surveillance. And if those meteoroids impact many satellites, that can knock out systems like GPS and Starlink.
