A star turns matter into energy in the process of

nuclear fusion

Which planet do most known extrasolar planets most resemble

Jupiter Neptune

The planet that most extrasolar planets resembles Jupiter.

Jupiter(apex)
Most of the confirmed Exoplanets are larger gaseous planets with large masses. These are easier to detect and confirm due to their size. They most resemble Jupiter, although many are thought to be much larger than our largest planet.

What is not standing in the way of astronomers getting a good view of distant stars

Forgetting to remove the telescope lens cap is not usually the problem.

The answer to this multiple choice question is "red shift" which is actually a useful phenomenon in viewing and analyzing the light from very distant stars. Light is shifted in wavelength by the movement of stars toward or more typically AWAY from the observer, or by moving through strong gravitational fields.

The sparse area surrounding a spiral galaxy is called

HALO

The farther a star is away from earth the more it is

red shifted

Hydrogen bombs and stars both produce energy with nuclear

fusion

Which best explains why the sun maintains its size and shape

Pressure caused by high temperatures are balanced by gravity

Which group of planets has more in common the inner planets or the outer planets

All the inner planets are terrestrial planets.

Select the star life cycle that is accarate

Nebula, white dwarf, red giant, black hole

All the iron molecules that are in your body were originally created by

a star

Which best describes the beginning of the big bang

A blowing of a balloon best describes the BIG BANG best

Select the star life cycle that is accurate.

star of one stellar mass, red giant, planetary nebula, white dwarf

Do All of the following are reasons why astronomers have difficulty looking at distant stars except

They don't understand how redshift affects stars.

What two things balance to maintain the shape of a star

Pressure and gravity

Match each event with its description

full moon

Why do astronomers find it difficult to locate extrasolar planets with telescope

light from the they orbit makes it difficult to locate extrasolar planets with telescope

Which of the following is not a reason that astronomers have trouble viewing distant stars

Distant stars give off less light
