What Are Bubbles in Space?

Rate this post

A new study has been published by scientists at the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland.

These scientists were researching how to deflect some of the radiation from the sun – also known as solar radiation. Their answer was using space bouncy houses, or “bubbles,” that could surround and protect the Earth.

What Are Bubbles in Space?

Bubbles in space are created when two stars collide and form a new, larger star. This process is called accretion. When this happens, the new star’s gravity pulls in material from its surroundings, creating a disk of dust and gas that surrounds the star. This disk can become unstable; if it does, it can collapse into a bubble.

Bubbles are commonly thought of as round and filled with air or gas, but in space, they can take on a variety of shapes. They can be caused by several phenomena, including the expansion of gases, the formation of stars, and even the death of stars.

Bubbles are often spherical but can also be elliptical, irregular, or ring-shaped. They can range in size from a few light-years to hundreds of light-years. And while they might look empty, some bubbles contain dust, gas, and even stars.

So what exactly causes bubbles in space?

One common cause is the expansion of gases. When hot gases expand rapidly, they can create bubbles. This can happen when a star explodes or when two galaxies collide.

Another cause of bubbles is the formation of stars. As young stars form from collapsing clouds of gas and dust, they can create cavities in space that look like bubbles. These star-forming regions are often surrounded by dense shells of gas and dust that help protect the newborn stars from the hostile space environment.

Finally, bubbles can also be created by the death of stars. When massive stars run out of fuel and collapse under their weight, they can create huge explosions called supernovas. These powerful blasts often carve out vast cavities that look like giant bubbles in space.

What is the Purpose of Space Bubbles?

Space bubbles, also known as cosmological bubbles or voids, are large empty regions of space. They are thought to be created by the universe’s expansion following the Big Bang.

Voids are important to cosmology because they help to explain the observed properties of the large-scale structure of the cosmos. In particular, voids can help to account for the fact that galaxies are not evenly distributed throughout space. Instead, they tend to be clustered together in groups and filaments, with vast regions of space in between.

How are the Bubbles Deployed in Space?

Depending on their intended purpose, bubbles are deployed in space by various methods. For example, some bubbles are deployed as part of experiments conducted by astronauts aboard the International Space Station. Other bubbles are released into space deliberately as part of efforts to study their behavior in microgravity.

One common method of deploying bubbles in space is using a “bubble chamber.” This device consists of a sealed container filled with a liquid, into which a gas is introduced. As the gas expands in the chamber, it forms bubbles that can be observed and studied.

Bubbles can also be generated spontaneously in space without the need for any special equipment. For example, when water droplets condense on surfaces in microgravity, they often form small spheres known as “space pearls.” These pearls eventually burst and release tiny bubbles into the surrounding environment.

How Will Space Bubbles Shield Earth From Radiation?

There are many dangers in space, one of which is radiation. Radiation can be harmful to both people and equipment. However, there is a way to shield against radiation, and that is by using space bubbles.

Space bubbles are created when a spacecraft releases a bubble of air into space. The bubble then expands and surrounds the spacecraft. The air inside the bubble acts as a barrier against radiation.

There are several benefits to using space bubbles for shielding.

  • First, they are very effective at stopping radiation.
  • Second, they are easy to create and do not require any special equipment.
  • Finally, they can be used over and over again.

Goals of the Bubbles in Space Project

The Bubbles in Space project is a long-term research effort to understand astrophysical plasmas dynamics better. The project has several goals, chief among them being to:

  • Understand how bubbles form and evolve in space
  • Study the effects of bubbles on their surroundings
  • Determine the role of bubbles in the overall energy budget of a system
  • Identify possible observational signatures of bubbles

The project employs a multi-disciplinary approach that includes theoretical modeling, numerical simulations, and observations to achieve these goals.


In conclusion, we have learned that bubbles in space are created when stars explode and release their energy. This energy creates a shockwave that expands outward and eventually forms a bubble. These bubbles can be incredibly large and often filled with gas and dust.
