How does a space probe maintain its trajectory while passing through the extreme gravitational field of the gas giants of our solar system?

The trajectory was not only "unhindered" - it was enhanced! Knowing mass of the planet you can calculate very precisely how the trajectory of a probe flying by will be affected. You modify the ...

Why is Jupiter called a "Gas Giant"?

Jupiter being a gas giant is not about its appearance, as another answer stated. It's only about the mass distribution of a planet. Jupiter's mass is 320 Earth masses, while we know from the Juno ...

They did not ! This is the trajectory of Voyager 1 at Jupiter. credits wikipedia

Why is Jupiter called a "Gas Giant"?

One reason they are called gas giants is because they are mostly composed of elements that are gaseous at Earth like temperatures and pressures. Jupiter is primarily composed of hydrogen with a ...

How deep could a gas giant communications network penetrate?

At JPL I participated in several studies concerned with telecommunication from depth at Jupiter (and other giant planets). In general, with radio telecom from within Jupiter's atmosphere, the lower ...

What would happen if we ignited one of the gas giants?

Combustion requires a fuel (hydrogen), an ignition source (your enormous explosive), and an oxidizer. There's a very small amount of oxygen in the atmospheres of the gas giants, almost all of it ...

How does gravity vary in a gas giant's interior?

I'll make a simplifying assumptions that the giant planets are very close to spherical and that the density inside these planets depends only on radial distance from the center of the planet. (This is ...

Why are the Rings of Saturn so much brighter than the other planets?

There are two factors at work here: The rings of Saturn are made of much more reflective material (water ice) than those of Jupiter, Uranus or Neptune. They simply have much more matter in them. This ...

How does gravity vary in a gas giant's interior?

That's a tricky question, if you want to go into enough detail. Generally, the gas giants consist mostly of gas, and you can derive the density and thus gravity if you know the equation of state of ...

How do we determine the internal composition of gas giants?

@SteveLinton gave the primary investigations for determining a giant planet's internal structure: gravity field structure and magnetic field structure. One minor correction: while the round-trip ...

What will be the effect if we stand on Jupiter?

If we ignore the atmospheric effects for a moment, let's see what gravity does as you descend into a planet (and this goes for all planets, rocky or gaseous). According to Newton's Shell theorem, ...

How do we determine the internal composition of gas giants?

Just about any data concerning a planet can contribute to our understanding of its internal structure one way or another. That said, probably the most powerful techniques at the moment are ...

Could a rogue planet's moons harbor life?

If the right chemical bath spews from hydrothermal vents on the floor of an ocean on this moon, then perhaps it could host creatures like the ones found around such vents on Earth. Here is a quote ...

Where do ice giants contain ice?

We can probe this matter a little more in-depth. This introductory reference describes all the giant or Jovian planets, noting that only the two more massive ones, Jupiter and Saturn, are made ...

Are there any experiments in progress designed to explore the interiors of gas giants like Jupiter or Saturn?

A good example is the Fourier imaging asteroseismology technique used by SYMPA: SYMPA, a dedicated instrument for Jovian seismology I. Principle and performance SYMPA, a dedicated instrument for ...
