are stars visible in space?

Fast exposure times means they can get good pictures of the bright Earth or lunar surface, but it also means no stars in the picture. Even in space, stars are relatively dim, and simply don't produce enough light to show up in photos set for bright sunlight.

Yes, instruments on satellites like the Bhangmeter are used to detect nuclear weapons detonations and enforce test ban treaties. ... So, there's factual confirmation that a 1.4 Mt nuclear explosion could be seen at night from at least 1,400 km away. This means that a nuclear explosion could definitely be seen from space.

Yes! In fact, most stars are bigger than the Earth. The diagram below compares the size of our sun with the sizes of the other planets in our solar system. The sun is much bigger than the Earth, and it isn't even a particularly large star.

Yes all the stars you can see belong to the Milky Way galaxy. ... The only naked eye objects not part of the Milky Way Galaxy are the three or four galaxies visible to the naked eye: the two Magellanic Clouds, the Andromeda Galaxy, and possibly the Triangulum Galaxy.

Pole stars of other planets are defined analogously: they are stars (brighter than 6th magnitude, i.e., visible to the naked eye under ideal conditions) that most closely coincide with the projection of the planet's axis of rotation onto the Celestial sphere.

There are about 1,000,000,000,000,000,000,000 stars in space, or about 10 raised to the 21 (10 21 power, roughly. This amount is about equal to the number of grains of sand on ALL of the beaches on planet Earth!!!

The total energy emitted per second by a star is called its luminosity. How bright a star looks from the perspective of Earth is its apparent brightness. The apparent brightness of a star depends on both its luminosity and its distance from Earth.

Yes, as one of the five brightest planets, Jupiter is visible without a telescope. Jupiter gives off a very bright white light and it will shine brighter than any other star in the sky.

Planets and stars are both observable to the human eye. Stars are just easier to see because they are so bright. Stars are large collections of gas that have huge pressures like a furnace at their core, whereas planets can be large but lack the same immense pressures.

Yes, indeed! Many nebulae are visible from Earth in a small and cheap telescope, and even to the naked eye (if you are standing in a sufficiently dark place).

To date, scientists have explored about 4 percent of the visible universe. That's made up of planets, stars and galaxies that astronomers can see.

The ability to detect radiation across the electromagnetic spectrum is vital for astronomers, as only a small fraction of the light in the universe comes in the visible part of the spectrum. That is why telescopes like Hubble are designed to capture images in wavelengths invisible to the naked eye.

Stars make their own light, just like our sun (the sun is a star — the closest star to Earth). But the stars are very, very far away from our solar system so they appear to be very tiny to us, even though up close they are large. The planets are much closer, inside our solar system.

If you connect the dots, you might imagine shapes called constellations. The constellations you see depend on where you live and the season. People near the North Pole can see the constellations that are to the north of Earth in space. People near the South Pole can see the constellations that are to the south.

Generally, stars are indeed bigger than planets. In fact all the stars you can see without a telescope are much bigger than the giant planet Jupiter. It is nuclear fusion that produces the light and heat from most stars. ... White dwarf stars are very small stars.

Yes, stars and constellations appear in the same place in the sky every night. This is because the Earth is moving so it looks like the stars and constellations are moving, but actually, we are!

Answer: The infrared radiations can detect the coolest and dimmest space objects.
