- Answer 3: The reason that you cannot see stars during the daytime is that the sun's rays overpower the faint light we see from the stars. During the night, when the sun's rays are blocked by the other side of the earth, it is possible to see the faint light of the stars shining in space.

Can astronauts see stars when they are in space? Actually, yes, astronauts can see stars in space. You can reproduce the experiment. Wait while a clear night, then look out of your window from a lit room. You'll be able to see, not immediately, but you will eventually see first magnitude stars.

- For a sphere, those two lines are parallel, which means they can never meet at your eye and you can never see both edges of a sphere at the same time. The Earth is almost a perfect sphere. So, neglecting distortion due to Earth's atmosphere, the strict answer to your question is: you must be an infinite distance away. Certainly, you've got to go farther than the International Space Station (240 miles), where you can only see about 5% of the full hemisphere Earth.

Why is it dark in space when there is the sun? Confidence votes 80.0K. It is not actually dark in space-let's do a little journey and try to understand what happens. You start to leave the earth in a rocket at 10 am in the morning on a sunny day.As you go up into the sky the sky will get darker and darker until at the edge of space the sky will go black and th stars will come out.he light is still there, but it does not scatter into blue sky like it does with Earth's atmosphere. That's why the sky looks black in outer space. But if you held up a piece … of paper, it would be illuminated very brightly in the sun.

How are astronomers able to measure how far away a star is? There is no direct method currently available to measure the distance to stars farther than 400 light years from Earth, so astronomers instead use brightness measurements. It turns out that a star's color spectrum is a good indication of its actual brightness.he Earth's orbit around the sun has a diameter of about 186 million miles (300 million kilometers). By looking at a star one day and then looking at it again 6 months later, an astronomer can see a difference in the viewing angle for the star.

How Far Can You See in the Universe? But we can see objects in space which are even more distant with the naked eye. The Moon is 385,000 km away and the Sun is a whopping 150 million km. Visible all the way down here on Earth, the most distant object in the solar system we can see, without a telescope, is Saturn at 1.5 billion km away.

- In our Solar System, we see light from our sun reflected off the planets. In more distant galaxies, light from many millions of stars takes a long time to reach the Earth. It takes light 4 years to reach the Earth from Sirius, a near neighbouring star. Using the Hubble telescope, we can see the light from the Eagle Nebula, which takes 7,000 years to reach the Earth.

- On my balcony (again: 5 million people conurbation) I can see many constellations-also the darker ones. You could use Google Sky Map or similar software to find some stars. What you will never see in a city, though, is the milky way as on the picture you quoted because it is not bright enough.

Explore and Find Sighting Opportunities Watch the International Space Station pass overhead from several thousand worldwide locations. It is the third brightest object in the sky and easy to spot if you know when to look up. Read More . Visible to the naked eye, it looks like a fast-moving plane only much higher and traveling thousands of miles an hour faster!

Why canât I see fabulous coloured nebulae with my telescope? FACT: No telescope makes PLANETS, NEBULAE or GALAXIES appear any brighter than they can be seen with the naked eye. Most people are very suprised by this statement, and many assert that it cannot possibly be true. The reason why is a bit difficult to explain, but bear with me, and I shall try.

Neutron star If the radius of the neutron star is or less, then the photons may be trapped in an orbit, thus making the whole surface of that neutron star visible, along with destabilizing orbits at that and less than that of the radius.

If Andromeda Were Brighter, This is What Youâd See And in about 4 billion years, Andromeda will selfishly collide with the Milky Way and the two will form an extra-huge galaxy. You won’t be here. Andromeda is also one of the very few objects outside our Milky Way that you can see in the night sky with our naked eye—if you know where to look.

How far can humans see? People with good eyesight, on a clear night, can see the Pinwheel galaxy, and that's about 27 million light years away. That's the most distant thing I know of that can be seen with the naked human eye. Vision is constrained by how clear the air is, and how much light is reflected or emitted by the object being viewed.

- Ever wonder why you can sometimes see the Moon when it’s still daylight out? Actually, you can see any celestial object in the daytime sky, provided the object is bright enough and large enough. The Moon fills both requirements. Another example is the planet Venus, which is often readily visible during the daytime, especially when it is near its greatest brilliancy.

- 2. An interesting question, but an example of the thing that cannot be seen would help a lot. 'With the naked eye' implies that it can be seen when using an (optical) instrument-e.g. Jupiter's satellites can't be seen with the naked eye, but can be seen through a telescope.

- The stars are light years away and are so far away they fade. The next closest star Proxima Centauri is so far it's light takes 4.22 years to reach Earth.

How do stars and planets look like from the telescope? In a telescope, stars pretty much look like they do without a telescope...just larger. For planets, nebulas and galaxies though, it's different. To see a good image of a planet in a telescope, you need a telescope that has high resolution capabilities, because you have to be able to use high magnification on planets.

5 Man-Made Things You Can See from Space (Plus One You Really Canât) No way. Again, people really can’t see much of any detail Earth-wise from u p there. On a similar note, it’s also effectively out of sight for the International Space Station’s crewmembers. Another persistent rumor holds that China’s Great Wall is the only man-made structure that’s visible from space.

Star Due to their great distance from the Earth, all stars except the Sun appear to the unaided eye as shining points in the night sky that twinkle because of the effect of the Earth's atmosphere. The Sun is also a star, but it is close enough to the Earth to appear as a disk instead, and to provide daylight.Other than the Sun, the star with the largest apparent size is R Doradus, with an angular diameter of only 0.057 arcseconds.he color of a star, as determined by the most intense frequency of the visible light, depends on the temperature of the star's outer layers, including its photosphere. Besides visible light, stars also emit forms of electromagnetic radiation that are invisible to the human eye.

How are stars important to the Milky Way? The Milky Way could get along fine without stars, as they make up only about 10% of its mass. Most of the mass is gas and dust and dark matter. While it is true that the galaxy would be dark without its stars, it would still exist. Source(s):

Beginnerâs Guide to Seeing the International Space Station (ISS) You can’t watch the ISS pass over during the middle of the day because in the daytime the sky is too bright (although some people with specialized equipment have seen it) and you cannot see the space station in the middle of the night, as it is in the Earth’s shadow and no light is being reflected from it.o check if there are any other spacecraft with the international space station during a pass, use the pass prediction app, or the Heaven’s Above Site. Seeing the ISS is an incredible sight! Just remember there are people on board that fast moving point of light!

- Uranus and Neptune are too far away to be seen with the naked eye. Venus, Mars, Jupiter and Saturn can be seen with the naked eye at certain times. It is also possible to see …Mercury, but more difficult because it is close to the Sun and it can only ever be seen for a brief time. All the planets are constantly moving and we are orbiting the Sun, so they won't be seen every night.
