What happened in 1995 that helped uncover something new to astronomers?

In 1995, astronomer Bob Williams wanted to point the Hubble Space Telescope at a patch of sky filled with absolutely nothing remarkable. Not much earlier, astronauts had dragged Hubble into the cargo bay of the space shuttle Endeavour and corrected a disastrous flaw in the prized telescope’s vision.

What was the significance of the Hubble Deep Field observations quizlet?

The Hubble Ultra Deep Field displays nearly 10,000 galaxies across the observable universe in both visible and near-infrared light. The smallest, reddest galaxies are among the youngest known, existing when the universe was just 800 million years old.

What is the general shape of the Milky Way galaxy?

What is the general shape of the Milky Way galaxy? a flattened disk in a spiral shape with a bulge in the center.

What is interesting about the status of Ceres in the solar system quizlet?

What is interesting about the status of Ceres in the Solar System? It is the only dwarf planet in the main asteroid belt. What do the four terrestrial planets and the four gas giant planets have in common? They all revolve about the Sun in the same direction.

What is the shape of the Analemma over the course of a full year?

The tilt of the Earth’s rotational axis to its orbital plane changes both the intensity of sunlight and the number of hours of sunlight received per day. What is the shape of the analemma over the course of a full-year? twice the tilt angle of the Earth’s spin axis.

What moons in our solar system could potentially support life?

The strongest candidates for natural satellite habitability are currently icy satellites such as those of Jupiter and Saturn—Europa and Enceladus respectively, although if life exists in either place, it would probably be confined to subsurface habitats.

What is the composition of a typical asteroid?

Asteroids are made mostly of rock — with some composed of clay and silicate — and different metals, mostly nickel and iron. But other materials have been found in asteroids, as well.

What are the 3 types of asteroids?

The three broad composition classes of asteroids are C-, S-, and M-types.

• The C-type (chondrite) asteroids are most common. They probably consist of clay and silicate rocks, and are dark in appearance.
• The S-types (“stony”) are made up of silicate materials and nickel-iron.
• The M-types are metallic (nickel-iron).

What is the brightest asteroid when viewed from Earth?

Vesta is the brightest asteroid visible from Earth. It is regularly as bright as magnitude 5.1, at which times it is faintly visible to the naked eye. Its maximum distance from the Sun is slightly greater than the minimum distance of Ceres from the Sun, though its orbit lies entirely within that of Ceres.

Is Juno still in space?

Proposed in 2003 and launched in 2011, Juno arrived at Jupiter on July 4, 2016. The prime mission will be completed in July 2021. NASA has extended the mission of its Juno spacecraft exploring Jupiter. The extended mission involves 42 additional orbits.

What is the purpose of Juno?

Juno’s primary goal is to reveal the story of Jupiter’s formation and evolution. Using long-proven technologies on a spinning spacecraft placed in an elliptical polar orbit, Juno will observe Jupiter’s gravity and magnetic fields, atmospheric dynamics and composition, and evolution.

What power does Juno make?

the sun
