Many astronomers are working hard to measure the Hubble constant using a variety of different techniques.

Unlike any space telescope before it, Hubble made astronomy relevant, engaging and accessible for people of all ages.

The distant worlds observed by Hubble and other telescopes are just the tip of the iceberg, according to a Hubble survey of the center of our Milky Way. The study revealed that our galaxy should be brimming with 100 billion planets, at least one planet for every star.

Suddenly, amid all the hubbub of the gale, there burst forth the wild scream of a terrified woman.

My hubby just got into an accident and I'm worried to death.

The Hubble Telescope has given us spectacular pictures from space, from the dramatic image of the Pillars of Creation in the Eagle Nebula, some 6,500 to 7,000 light years from Earth, to a snapshot of nearly 10,000 galaxies, including some that may be among the most distant known, existing when the universe was just 800 million years old.

Once in orbit, a defect in the optical mirrors of the Hubble Space Telescope prevented the clarity that scientists had hoped for when viewing images provided by the telescope.

Algeria should become a logistics hub.

Since the magnitude of the spherical aberration was well-defined, engineers designed a set of mirrors that astronauts could place aboard Hubble during the previously planned first servicing mission.

Some space probes, such as Pioneer 10, fly out of our solar system and never come back. Other space probes, like the Hubble Space Telescope, stay in orbit around the same planet their whole life.
