Who is James Webb?

Who is James Webb?

James Edwin Webb, (born Octo, Tally Ho, North Carolina, U.S.—died Ma, Washington, D.C.), American public servant and administrator of the National Aeronautics and Space Administration (NASA) during the Apollo program (1961–68).

Why is the telescope named James Webb?

This space-based observatory is named after James E. Webb (1906- 1992), NASA's second administrator. Webb is best known for leading Apollo, a series of lunar exploration programs that landed the first humans on the Moon.

What is the best telescope in the world?

The Giant Magellan Telescope

Is Hubble still in space?

Hubble is the only telescope designed to be maintained in space by astronauts. ... The telescope was still operating as of Ap, its 30th anniversary, and could last until 2030–2040. One successor to the Hubble telescope is the James Webb Space Telescope (JWST) which is scheduled to be launched in late 2021.

How far back can Hubble see?

about 10-15 billion light-years

How long will Hubble last?

Being realistic, I think Hubble's got a good five years left. And we're operating the observatory in a way meant to keep it scientifically productive out to 2025.

How far is Hubble from Earth?

about 547 kilometers

Are there colors in space?

Space emits a range of wavelengths of light, some we can see others we can't. ... However it doesn't record any color but it has got filters which enable it to capture only a certain required wavelength of light.

How many galaxies are there?

XDF (2012) view: Each light speck is a galaxy, some of which are as old as 13.

Which type of galaxy is the largest?

elliptical galaxies

What is the oldest thing in the universe?

GRB 090423 was also the oldest known object in the Universe, apart from the methuselah star. As the light from the burst took approximately 13 billion years to reach Earth.

What is the largest body in the universe?

Cosmic Record Holders: The 12 Biggest Objects in the Universe

  • Largest black hole: TON 618. ...
  • Largest galactic farts: Fermi Bubbles. ...
  • Largest single object: Protocluster SPT2349-56. ...
  • Largest galactic collection: Shapley Supercluster. ...
  • Largest supercluster: Laniakea Supercluster. ...
  • Largest quasar collection: Huge-LQG. ...
  • Largest thing in the universe: Hercules-Corona Borealis Great Wall.

What is the largest black hole in the universe?

Currently the largest known black hole, powering the quasar TON 618, has a mass of 66 billion solar masses. TON 618's enormous bulk led scientists to speculate whether or not even larger black holes exist, and if there is any upper limit to their sizes.

Has anyone been in a Blackhole?

What would happen if you fell into a black hole? It certainly wouldn't be good! But what we know about the interior of black holes comes from Albert Einstein's General Theory of Relativity. ... Fortunately, this has never happened to anyoneblack holes are too far away to pull in any matter from our solar system.

What happens if 2 black holes collide?

When two black holes spiral around each other and ultimately collide, they send out gravitational waves - ripples in space and time that can be detected with extremely sensitive instruments on Earth. ... If confirmed, it would be the first known light flare from a pair of colliding black holes.

Can a black hole die?

When particles escape, the black hole loses a small amount of its energy and therefore some of its mass (mass and energy are related by Einstein's equation E = mc2). Consequently, an evaporating black hole will have a finite lifespan.

What would happen if a black hole hit Earth?

If a black hole were to form from the Earth itself, it would create an event horizon just 1.

Can a black hole collapse on itself?

Left alone, black holes lose mass due to 'Hawking radiation', so that their event horizons are slowly shrinking. ... But, the interior of the black hole, or its 'singularity' (the point at which all the black hole's matter is concentrated) has already reached the limit of its density and cannot 'collapse' any further.

Does time exist 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. ... Inside the black hole, the flow of time itself draws falling objects into the center of the black hole. No force in the universe can stop this fall, any more than we can stop the flow of time.

What is inside a Blackhole?

A black hole is a tremendous amount of matter crammed into a very small — in fact, zero — amount of space. The result is a powerful gravitational pull, from which not even light can escape — and, therefore, we have no information or insight as to what life is like inside.

Is the universe going to end?

The fate of the universe is determined by its density. The preponderance of evidence to date, based on measurements of the rate of expansion and the mass density, favors a universe that will continue to expand indefinitely, resulting in the "Big Freeze" scenario below.

Can you see a black hole?

You can 'see' the closest known black hole to Earth with the naked eye. There is a black hole in our backyard. Astronomers have found the closest black hole yet at just 1000 light years from Earth, close enough to see the stars that orbit it without a telescope.

Will a black hole hit Earth?

There are no black holes close enough to Earth to affect us. ... This black hole is 6.

Should we be worried about a black hole?

Don't worry: Despite its proximity to Earth, the black hole is no danger to us. ... Astronomers estimate there are hundreds of millions of black holes in our galaxy. The latest discovery gives them hope that there are others lurking around nearby stars, perhaps even some of the most familiar points of light in our sky.

What are the 4 types of black holes?

There are four types of black holes: stellar, intermediate, supermassive, and miniature. The most commonly known way a black hole forms is by stellar death.

Will the sun become a black hole?

Will the Sun become a black hole? No, it's too small for that! The Sun would need to be about 20 times more massive to end its life as a black hole. ... But the Sun's not big enough for this fate, either: It has only about one-tenth of the mass needed to eventually become a neutron star.

Why is space black?

Around Earth and the inner solar system, for example, space is filled with dust particles that get lit up by the sun, creating a diffuse glow over the entire sky. But that dust isn't a problem out where New Horizons is. Plus, out there, the sunlight is much weaker.

What happens when a black hole dies?

Over time they shrink down to nothing and simply pop away in a flash of energy. It's not exactly fast. A good size black hole — say, a few times more massive than the sun — will take about 10^100 years to eventually evaporate through this process, known as Hawking Radiation.
