It was repeated by the Abbasid astronomers.

'Al Ma'mun's astronomers repeated the Greek experiments

We have astronomers in place with telescopes

Today, the country is believed to have about 60 working astronomers, more than half of all the astronomers working in Africa.

Some of the world's astronomers have telescopes nearby.

And the regular astronomers were scornful about this.

The phenomena foreseen by the astronomers is taking place.

If astronomers were frogs perhaps they'd see Kermit the Frog.

(Laughter) If astronomers were frogs, perhaps they'd see Kermit the Frog.

Second you can tour the universe with astronomers as your guides.

Or was it possible that astronomers had incorrectly measured the galaxy's mass?

Astronomers estimate that little asteroids like that come about every hundred years.

With these figures, Al Ma'mun's astronomers were able to estimate the Earth's circumference.

That's how radar catches you speeding and how astronomers measure the rotation of galaxies.

In the 1920s, astronomers studying the nebuli wanted to figure out how they were moving.

And looking at this model makes people wonder, why do astronomers want to ditch Pluto?

While Pluto shrank astronomers started to find other, similar objects orbiting in the same zone.

So, how do astronomers prove that there is a lot of mass inside a small volume?

But it's relatively challenging for astronomers who want to look through the atmosphere to astronomical sources.

His discovery solved a lot of mathematical problems that astronomers were having with planetary orbit measurements.

The next year astronomers found another small planet in the same area and named it Pallas.

It was a crisis, and astronomers and physicists scrambled to find a mistake in their calculation.

He created this image for this, and he's actually one of the astronomers who works for them.

Astronomers are now almost able to tell us what the product of the first three terms is.

Back in the 1801, astronomers found a new planet in the huge gap between Mars and Jupiter

You'll notice that a lot of comets are named after people you never heard of, amateur astronomers?

Orbital simulations are used to determine what orbital parameters (including orbital distance) produce the observations seen by astronomers.

This is a collaboration between astronomers and students at the universities of Helsinki, Copenhagen, Uppsala (Sweden) and Oslo.

The Very Large Telescope is one of these things that astronomers do they name their telescopes rather unimaginatively.

20 years ago, 30 years ago, only big professional astronomers with very big telescopes could see far into space.

Now, most astronomers have a favorite star, and mine today is a star that's labeled up there, SO 2.

Twenty years ago, 30 years ago, only big professional astronomers with very big telescopes could see far into space.

Using these techniques, astronomers predict how fast stars at different distances from the center of the galaxy should move.

It is apparently in opposition to the principle of mediocrity, assumed by famed astronomers Frank Drake, Carl Sagan, and others.

It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard, et al.

It was discovered by a team of astronomers from the University of Hawaii led by Scott S. Sheppard in 2003.

Data on Kepler 40 was analyzed by a team of French and Swiss astronomers, who first tested for false positives.

By the following century, the idea of the stars being the same as the Sun was reaching a consensus among astronomers.

Once again, astronomers recategorized the solar system and grouped these distant objects, including Pluto, into a new area called Kuiper belt.

Modern astronomers have discovered the faint remnant of this explosion and determined that it was only 7,100 light years from the Earth.

Over the past several years, astronomers have learned a great deal about asteroids and comets that strike the Earth at random intervals.

They clash not only with the West, but with the golden age of Islam, when Muslim astronomers, mathematicians, physicians, philosophers, and poets flourished.
