The atmosphere of the sun is composed of several layers, mainly the photosphere, the chromosphere and the corona. It’s in these outer layers that the sun’s energy, which has bubbled up from the sun’s interior layers, is detected as sunlight. The lowest layer of the sun’s atmosphere is the photosphere.

Surface. The surface of the Sun, the photosphere, is a 300-mile-thick (500-kilometer-thick) region, from which most of the Sun’s radiation escapes outward. This is not a solid surface like the surfaces of planets. Instead, this is the outer layer of the gassy star.

Describes the surface features of the Sun, including sunspots, solar prominences, solar flares, and coronal mass ejections.

• How Big is the Sun? The Sun is the largest object in the Solar System, accounting for 99.86% of the mass.
• Mass of the Sun. The mass of the Sun is 1.98892 x 1030 kilograms.
• Diameter of the Sun.
• Radius of the Sun.
• Gravity of the Sun.
• Density of the Sun.
• Volume of the Sun.
• Circumference of the Sun.

Some features of the Sun’s surface include sunspots, solar flares, and prominences.

Here are some other physical characteristics of the Sun. Surface: The Sun, like all stars, is a glowing ball of gas. Even if a spaceship could withstand the heat, it could not land on the Sun because the Sun’s surface is not solid. An atmosphere is a layer of gases surrounding an object in space.

The enormity of the sun’s surface paired with its capability of generating of tens of thousands of watts of sound energy per meter makes the sun astronomically loud.

Sound intensity decreases with distance, which means that the Sun would deliver a much smaller 125 decibels to the surface of our planet. In comparison, 120 decibels is a train horn about one metre away whereas 130 decibels is physical pain. In general, the lower the pitch, the bigger the star.

The answer might surprise you, as solar physicists estimate that the solar surface noise would be approximately 100dB by the time it reaches Earth! The enormity of the sun’s surface paired with its capability of generating of tens of thousands of watts of sound energy per meter makes the sun astronomically loud.

100 – 120 decibels: For example, a bulldozer, impact wrench, or motorcycle. 120 – 140 decibels: Such as, a rock concert, auto racing, or a hammer pounding a nail. 125 – 155 decibels: Like, firecrackers or fireworks, or a jet engine.

But those are other stories.) In contrast to the swift-traveling vibrations in electrical and magnetic fields that we call light, the sounds of the universe are carried by vibrations in spacetime called gravitational waves.

The speed of sound through air is about 340 meters per second. Light will travel through a vacuum at 300 million meters per second. So they’re totally different scales. No information can propagate faster than the speed of light.

Like bubbles rising in a pot of boiling water, sound waves move through a star’s interior because of temperature changes. But unlike on these planetary bodies, stellar sound waves are generated continuously by turbulence in the near-surface layers of stars.

Light travels in waves, and, like sound, can be slowed depending on what it is traveling through. Nothing can outpace light in a vacuum. However, if a region contains any matter, even dust, light can bend when it comes in contact with the particles, which results in a decrease in speed.

Space is a vacuum — so it generally doesn’t carry sound waves like air does here on Earth (though some sounds do exist in outer space, we just can’t hear them).

Remember there is no atmosphere on the moon, and without an atmosphere or a medium by which sound waves can travel there is no sound. This is not the case on Mars because that planet has an atmosphere, even though it is insufficient to support un-protected human life, it is sufficient to allow transmission of sound.

Scientists have picked up “sounds” from solar system bodies, including radio waves from Saturn and vibrations in the magnetic field of Comet 67P/ Churyumov-Gerasimenko. The Mars 2020 rover may carry a microphone to the Red Planet, to make the first traditional sound recordings of another world.

When astronauts are out in space, they can whistle, talk, or even yell inside their own spacesuit, but the other astronauts would not hear the noise. In fact, the middle of space is very quiet. Sound travels in waves, and it moves at different speeds through air or water or other materials.

The song fits the video well: Without any air to transmit sound, space is indeed completely silent. Russian cosmonaut Sergey Ryazanskiy, Italian astronaut Paolo Nespoli and American astronaut Randy Bresnik captured the stunning footage from August through October 2017 on the International Space Station.

Deep within Neptune and Uranus, it rains diamonds—or so astronomers and physicists have suspected for nearly 40 years. The outer planets of our Solar System are hard to study, however. Only a single space mission, Voyager 2, has flown by to reveal some of their secrets, so diamond rain has remained only a hypothesis.
