What are 2 things Hubble has discovered?

What are 2 things Hubble has discovered?

Helped pin down the age for the universe now known to be 13.8 billion years, roughly three times the age of Earth. Discovered two moons of Pluto, Nix and Hydra. Helped determine the rate at which the universe is expanding. Discovered that nearly every major galaxy is anchored by a black hole at the centre.

What is the most important image?

Hubble Deep Field: The Most Important Image Of The Universe Ever Taken. In 1995, astronomers pointed the Hubble Telescope toward a seemingly empty spot in the sky.

What does the Hubble Deep Field image show?

Called the Hubble Ultra Deep Field (HUDF), the image contains as many as 10,000 galaxies of all shapes, sizes, colors, and ages. Taken by NASA’s Hubble Space Telescope, this benchmark view represents a “core sample” of galaxies at various distances and therefore different eras in our universe’s history.

What do Hubble images actually look like?

Any iconic image of the universe you can think of was probably taken by the Hubble Space Telescope. Take the Eagle Nebula, for example, which is shown below. What you might not realize is that this spectacular, colored photograph was originally black and white.

How long does it take for the Hubble to take a picture?

One of the most detailed image is the Ultra-Deep Field that required 11.3 days with 112 exposures for the 435 and 606 nm and 288 exposures for the 775 and 850 nm. For a total exposure time of around 1 million of seconds.

Are the colors in Hubble pictures real?

A typical Hubble image is made from a combination of black-and-white images representing different colors of light. For one thing, Hubble doesn’t use color film — in fact, it doesn’t use film at all. Rather, its cameras record light from the universe with special electronic detectors.

What could Hubble see if pointed at Earth?

If the Hubble Space Telescope (HST) could observe Earth from its orbit 570 kilometers (350 miles) above Earth’s surface, it would in theory be able to see objects as small as 0.3 meters (30 centimeters).

Can Hubble look at Earth?

As Phil Plait of Bad Astronomy pointed out, Hubble looks at Earth pretty regularly. The real problem is that Hubble is moving over the surface at over 7 kilometers per second. Even a short exposure would be a blur.

Can Hubble look at the sun?

Hubble cannot look at the Sun directly and so must use reflected light to make measurements of the Sun’s spectrum. This ground-based picture from Lick Observatory shows the area covered in Hubble’s photomosaic with the Wide Field Planetary Camera 2.
