How does NASA take pictures of galaxies?

Powerful telescopes like Hubble, Chandra, and Spitzer (and soon, James Webb) capture images of our galaxy in many different light wavelengths, which astronomers piece back together so they can see past the gas and dust as far into the center as possible.

How did NASA take a picture of the galaxy?

Hubble Ultra Deep Field-Infrared



In 2009, Hubble captured near-infrared light wavelengths in the same region as the Ultra Deep Field, revealing galaxies formed just 600 million years after the Big Bang.

How did NASA take a picture of the universe?

Hubble uses a digital camera. It takes pictures like a cell phone. Then Hubble uses radio waves to send the pictures through the air back to Earth.

Do we actually have pictures of galaxies?

A telescope network that has spent years staring into deep space has finally delivered some of the most gloriously detailed images we’ve ever seen of other galaxies.

What does NASA use to take pictures from outer space?

One of the most famous is the Hubble Telescope. The Hubble was designed as a long range telescope and placed in orbit around the Earth in order to get clearer photos without an atmosphere. It has long outlived the design specifications yet still delivers amazing views of galaxies and nebulae.

Is Earth in the Milky Way?

Our solar system—which includes the sun, Earth, and seven other planets—is part of this galaxy, called … you guessed it … the Milky Way. The Milky Way contains hundreds of billions of stars like our sun.

What do galaxies really look like?

Most galaxies are flat, but there are different shapes — some are spirals, some are elliptical, and some are irregular. What does the Milky Way look like? Our Milky Way galaxy looks a little like a pinwheel.

What does space smell like?

A succession of astronauts have described the smell as ‘… a rather pleasant metallic sensation … [like] … sweet-smelling welding fumes’, ‘burning metal’, ‘a distinct odour of ozone, an acrid smell’, ‘walnuts and brake pads’, ‘gunpowder’ and even ‘burnt almond cookie’.

Why is space dark?

Because space is a near-perfect vacuum — meaning it has exceedingly few particles — there’s virtually nothing in the space between stars and planets to scatter light to our eyes. And with no light reaching the eyes, they see black.

Can astronauts see color in space?

Read on to learn more about color in space. Believe it or not the human eye can see about 7,00,000,000 colors. But, did you know that colors exist that you cannot see? Color does not change in space, because the wavelengths remain the same.

How cold is space?

Hot things move quickly, cold things very slowly. If atoms come to a complete stop, they are at absolute zero. Space is just above that, at an average temperature of 2.7 Kelvin (about minus 455 degrees Fahrenheit).

Is there sound in space?

No, there isn’t sound in space.



This is because sound travels through the vibration of particles, and space is a vacuum. On Earth, sound mainly travels to your ears by way of vibrating air molecules, but in near-empty regions of space there are no (or very, very few) particles to vibrate – so no sound.

What’s the gravity of a black hole?

The black hole would have the same gravity as the sun. Earth and the other planets would orbit the black hole as they orbit the sun now. The sun will never turn into a black hole.

What is inside a white hole?

In general relativity, a white hole is a hypothetical region of spacetime and singularity that cannot be entered from the outside, although energy-matter, light and information can escape from it.

Do wormholes in space exist?

Einstein’s theory of general relativity mathematically predicts the existence of wormholes, but none have been discovered to date. A negative mass wormhole might be spotted by the way its gravity affects light that passes by.

Does time stop in a black hole?

Near a black hole, the slowing of time is extreme. From the viewpoint of an observer outside the black hole, time stops. For example, an object falling into the hole would appear frozen in time at the edge of the hole.

What is the nearest black hole to Earth?

In 2020, a team of astronomers with the European Southern Observatory (ESO) discovered the closest black hole to Earth in the HR 6819 system, just 1,000 light-years away, only to have other scientists dispute the findings.

How do you destroy a black hole?

Video quote: There is nothing we could throw at a black hole that would do the least bit of damage to it even.

Can you survive a black hole?

Regardless of the explanation, we do know that it is highly unlikely that anyone entering a black hole would survive. Nothing escapes a black hole. Any trip into a black hole would be one way. The gravity is too strong and you could not go back in space and time to return home.

Will Earth be eaten by a black hole?

Will Earth be swallowed by a black hole? Absolutely not. While a black hole does have an immense gravitational field, they are only “dangerous” if you get very close to them.

Would you feel pain in a black hole?

If you’re falling into a stellar black hole, you’ll start feeling uncomfortable within 6,000 kilometers (3,728 miles) of the center, long before you cross the horizon [source: Bunn]. Either way, spaghettification leads to a painful conclusion.

What happens if Earth goes in a black hole?

What would happen if an asteroid-mass black hole were to hit Earth? In short, catastrophe. The black hole would puncture our planet’s surface like a hot knife through butter, but it would immediately begin to slow down because of its gravitational interaction with Earth.

What would happen if the Sun exploded?

The good news is that if the Sun were to explode – and it will eventually happen – it wouldn’t happen overnight. … During this process, it will lose its outer layers to the cosmos, leading to the creation of other stars and planets in the same way that the violent burst of the Big Bang created Earth.

What happens if you get sucked in a black hole?

Einstein’s general relativity says that when matter is pulled into a black hole, its information is destroyed – but quantum mechanics says that cannot happen. As a result, black holes are an incredible theoretical playground for astrophysicists and mathematicians, attempting to reconcile the two theories.

Is there a white hole?

White holes are theoretical cosmic regions that function in the opposite way to black holes. Just as nothing can escape a black hole, nothing can enter a white hole. White holes were long thought to be a figment of general relativity born from the same equations as their collapsed star brethren, black holes.

What is inside of a black hole?

The singularity, stretched into a ring, is rotating at such a fantastic pace that it has incredible centrifugal force. And in general relativity, strong enough centrifugal forces act like antigravity: they push, not pull. This creates a boundary inside the black hole, called the inner horizon.

What is a black hole in space?

A black hole is an area of such immense gravity that nothing—not even light—can escape from it. Black holes form at the end of some stars’ lives. The energy that held the star together disappears and it collapses in on itself producing a magnificent explosion.
