No, stars cannot be touched. Stars are so far away that they are completely inaccessible to us physically. They are made mostly of hydrogen and helium gases and the temperatures in their cores are so hot that even if it were possible to reach them, touching them would not be possible.
Furthermore, the immense gravity of some stars makes it almost impossible for anyone to travel there or even get close to them. The approximate distance between Earth and the closest star, Proxima Centauri, is 4.2 light-years; this is about 25 trillion miles away.
Therefore, stars can be observed, but cannot be touched.

Can u Touch stars in space?
No, you cannot physically touch a star in space. Stars are composed primarily of hydrogen and helium gas and are much too far away and too hot (up to millions of degrees on the surface) for us to get close enough to physically touch them.
Even if you could get close enough to a star to touch it, the extreme temperatures and gravitational forces would make it impossible.
Why can’t astronauts see stars?
Astronauts can’t see stars when they are in space because the Earth’s atmosphere helps to filter out the sunlight enough so that stars can be seen at night. In space, however, there is no atmosphere to filter out the sunlight, and thus the night sky appears completely black.
Astronauts also need to take into account the brightness of the Sun and its reflection off of their spacecraft and the Earth’s atmosphere. These added brightnesses often overwhelm more distant stars, making them difficult to see.
Additionally, when a spacecraft is orbiting the Earth, its rate of speed and angle of orientation to the Earth’s surface can make it difficult to spot stars in the night sky.
Is it possible to reach the stars?
Reaching the stars is a difficult but not impossible task. Astronomers have long dreamed of sending manned missions to other stars, beyond our own Sun. While our current technology is not capable of taking people to the stars, scientists are actively problem-solving to make this a reality.
One way to reach the stars is through a process called interstellar travel. This would involve a space craft or starship travelling much faster than the speed of light, which would propel astronauts to their destination.
It is hypothesized that a form of propulsion could be developed that would allow the spacecraft to exceed the speed of light by using anti-matter, dark energy, or other forms of exotic matter.
Another promising technology is the Breakthrough Starshot project, which would use a giant light sail and powerful laser to propel a micro spacecraft to the stars. This method has been proposed to gain a fraction of the speed of light to enable fast interstellar travel.
Although we are not yet capable of reaching the stars, research and development continues with the aim of achieving this fantastic feat in the future.
Why are there no stars in pictures taken in space?
There are no stars in pictures taken in space because stars are so distant and appear to have no movement compared to other celestial objects such as planets, comets and the sun. In order to get a star to appear in a photograph taken from a spacecraft, a very long exposure would be required, making the image appear blurred.
This is because the spacecraft is always in motion giving the stars a “streak” if the exposure is too long. The light from stars is also very faint in comparison to other celestial bodies, making them difficult to capture in a photograph.
Furthermore, in order to capture stars in an image, a large amount of light pollution must be avoided, which is not always possible when a spacecraft is in low Earth orbit or even in deeper space.
What does space smell like?
The smell of space is described as a sweet, smoky aroma, like the odor of seared steak. Some astronauts have said it smells like burning metal or sparks, and that it is similar to an ozone or “gunpowder” smell.
Other astronauts have likened it to the smell of welding. Others have reported smelling a sweet or burnt smell, or being able to smell nothing at all. It has been theorized that some of the smells astronauts have described are attributed to a combination of meteoroids burning up in the atmosphere and other particles beyond Earth’s atmosphere.
Why is space cold if the sun is hot?
Space is actually quite cold compared to the sun, and this is due to the fact that there is no atmosphere in space to help retain the heat. The sun is composed of extremely hot plasma and is protected by a thick blanket of gases, meaning that its energy and heat can be more easily controlled and kept in place.
By comparison, space is full of mostly empty vacuum, so the heat generated by the sun dissipates quickly. Additionally, the extreme distances between stars and planets means that the heat generated by the sun needs to travel for vast amounts of time and space before it reaches a planet or other object, reducing its thermal energy significantly during this journey.
Therefore, even though the sun is hot, space is much colder and usually measures around -455 degrees Fahrenheit.
Why do we see stars on Earth but not in space?
We see stars on Earth because we are able to observe starlight that has traveled for hundreds of thousands of years until it reaches our atmosphere. Our atmosphere works like a filter, allowing us to see a representation of stars from a great distance away, like a distant lightbulb.
In outer space, however, there is no atmosphere to filter the light so we don’t see stars visually. Instead, because space is a vacuum, we can detect stars by measuring their electromagnetic radiation emitted in both visible and infrared light.
Even though stars are constantly emitting light in every direction, in space, stars appear to look much dimmer than they do in our Earth’s atmosphere due to lack of filtering.
Does NASA have pictures of stars?
Yes, NASA has pictures of stars. NASA has taken a number of stunning images of stars thanks to its various space telescopes, such as the Hubble Space Telescope. NASA even provides the public with access to its library of star photos, so people can view and download the images.
The images provide beautiful views of galaxies and star clusters, which can help people learn more about space and the universe. Through its scientific and technological achievements, NASA has provided humanity with some of the most stunning images of stars that have ever been captured.
Can you walk on a star?
No, it is not possible to walk on a star. Stars are huge celestial objects made up of plasma, which is a combination of gas and magnetic fields. Stars are extremely far away and they also move at very high speeds as they orbit around our galaxy.
Additionally, the temperatures on stars are usually very high and not suitable for human survival. These temperatures are so hot that the surface of a star cannot hold a solid form and all matter on it is in a gaseous or plasma state.
Therefore, it is impossible for anyone to walk on a star.
What would happen if you stood on a star?
Standing on a star is not possible since stars are massive balls of plasma composed mostly of hydrogen and helium, meaning that they are extremely hot, usually millions to billions of degrees Celsius.
The temperatures on a star’s surface are much too extreme for any human to ever be physically able to stand on one, since you would almost immediately be vaporized due to the extreme heat. If you tried, the intense radiation from the star might even reach you whereabouts, before you had a chance to get too close, making it impossible to ever reach the surface of one.
Could we live around a neutron star?
Unfortunately, the answer is no. Neutron stars, the dense remnants of supernova explosions, put out intense radiation in the form of x-rays, gamma rays, and charged particles that make the environment around them extremely hostile for any sort of potential life.
The radiation emitted from a neutron star has so much power that it is able to strip away electrons from atoms and molecules of any material surrounding it, rendering them unable to support life. Additionally, the extreme temperatures and gravitational forces experienced near a neutron star exceed any amount that life could ever hope to withstand.
For these reasons, it is impossible for any life to survive near a neutron star.
Can a black hole rip a neutron star?
No, a black hole cannot rip a neutron star. Although black holes have a strong gravitational force, the gravity of the neutron star is too strong for the black hole to overpower it. Furthermore, neutron stars have incredibly dense matter, which makes them almost impossible to disrupt or break apart.
In addition, neutron stars also have incredibly powerful magnetic fields that protect them from forces, such as a black hole, that could potentially harm them. If a black hole were to come close to a neutron star, they would experience a powerful attraction due to their gravitational forces, but this would likely cause the two to orbit each other rather than the black hole ripping the neutron star apart.
What happens if 2 stars collide?
When two stars collide, the event is known as a stellar collision. The outcome of a stellar collision varies depending on the type of stars involved and their respective masses. If the two stars have similar masses, they will gravitationally bond together, creating a single star with a higher mass than either of the original stars.
This process is also known as a merger. If the two stars have vastly different masses, the larger of the two stars will deform to become an ellipsoidal shape, devouring the smaller star and growing in mass.
Similarly, the smaller star will be completely consumed by the larger star, leaving no remnant.
In some cases, these types of collisions can result in a powerful explosion known as a supernova. The resulting energetic shock waves from the supernova can cause other nearby stars to be ejected from their orbits into interstellar space, which is known as a galactic ejection.
The more energetic stellar collisions can also result in the formation of a black hole or neutron star. These objects have such a massive gravitational pull that even light cannot escape their grasp, making them virtually invisible.
Can life exist in a star?
No, life as we know it cannot exist in a star. The environment of a star is far too harsh for any known life form to survive. The extreme temperatures and pressures inside a star make it impossible for complex molecules and organisms to exist.
Even if some sort of bacteria or virus could survive in such an extreme environment, they would be unable to find the energy necessary to sustain life. The temperatures within a star continually increase with the distance from its center, reaching a few thousand degrees Kelvin (thousands of degrees Celsius) at the core.
Along with intense radiation and ultraviolet light, the intense heat would be unbearable for any life form. Additionally, since stars are composed largely of hydrogen and helium, there is no oxygen present which is required for almost all complex life forms as we know them.
