What planet has the most visible rings

Saturn is the planet with the most visible rings. Saturn's rings are one of the most iconic symbols of astronomy.
Saturn is the planet in our solar system that is famous for the rings.

Which function is performed by the ozone layer

Ultraviolet rays from the sun are prevented from reaching Earth.

What about Earth allows it to maintain bodies of water

moderate temperatures and strong gravity (APEX)

Gas giants have many more moons than terrestrial planets due to having higher

gravity

An explosion of a star

When a star explodes, it is referred to as a nova. If the star is large enough, it will create a super nova. And if the star is dense enough, it does not explode, but instead collapses on itself and forms a black hole

What Is the terrestrial planet that has no atmosphere

what is the terrestrial planet that has no atmosphere

What is the smallest of the terrestrial planets

Mercury is the smallest of the terrestrial planets.

Contains mostly older stars with a red color

elliptical galaxy....

Which best describes stellar equilibrium

For most of the life of a star, there is a balance between pressure caused by heat in the core and weight of gravity the star's mass.

There is an equilibrium, or very close to it, all throughout the star. At each point in the star, the mass above is pressing down due to gravity, but because the matter in the star is so hot, there is a balancing pressure holding up the mass above. At the core, the temperature is highest and the pressure is greatest and both decrease towards the surface.

Once the fuel at the center of a star become exhausted, the stellar equilibrium is lost and the life of the star begins to fade. Depending on the mass of the star, this may be relatively quiet (small stars) or bigger stars can produce a super nova and for the largest stars the end can be a black hole.

Stellar equilibrium is a balance between what two things

Outward pressure and inward gravity

Astronomers are able to determine the speed at which certain redshifted stars move using

This is the Doppler Effect.

Astronomers use "spectroscopy" to analyse redshifts.

Titan is a moon that orbits around

Saturn

What was found by astronomers who noticed a strange pattern in the orbit of Uranus

Neptune

The dense remains of a star

Depends on the mass of the host star.

It could be:-

  1. White Dwarf
  2. Neutron Star
  3. Black Hole
Why isn't it possible to have a full moon and a solar eclipse at the same time

In a full moon, the Moon is on the other side of Earth from the Sun. In a solar eclipse, the Moon is on the SAME side of the Earth as the Sun.

Radiotelescopes reveal that space is full of

cosmic microwave background radiation.

A detected apparent change in the pitch caused by the motion of a sound source or of an observer is called

The Doppler effect.

The Doppler effect.

The Doppler effect.

Is it true Pluto has a moon

Pluto has five moons.

The giant red spot is found on the planet

the giant red spot is found in the planet jupiter.

Which gas giants have more moons than the terrestrial planets

All of our Solar Systems gas giants have more moons than the terrestrial planets.

Jupiter (63), Saturn (62), Uranus (27) and Neptune (13).

What is a name that is given to a new star

first it is a nebula, a large cloud of gas and dust that is spread out in an immense volume. After it forms a protostar, which is a large cloud of gas and dust with enough mass to form a star. Then it matters what is that star's mass. it could be a high mass star or a small or medium mass star like our sun.

Why is true of Pluto

Pluto barks. Goofy talks.

What has the most habitable other than earth

Mars

When the moon is on the side of the earth and opposite the sun

When the moon is on the side of the earth opposite the sun you get a full-moon.

Which is true of pluto

Pluto has a moon that is about half its size

Which contributes to the lack of evidence of the period of heavy bombardment on earth

Plate movements
