which main problem is being solved by the Hubble space telescope is it
burning of telescope as they get closer to star, cutting through thick atmosphere to photograph stars, identifying the brightest stars in the galaxy, or bending of starlight by the atmosphere
The main problem being solved by the Hubble Space Telescope is the distortion caused by the bending of starlight by the atmosphere. The Hubble's location in space outside the Earth's atmosphere allows it to capture extremely clear and detailed images of celestial objects that would otherwise be blurred by atmospheric interference.
how do small objects appear when viewed of a shorter distance? is it they appear to be the same size, they are not visible at all, they appear larger, or they appear smaller
When viewed from a shorter distance, small objects generally appear larger. This is due to the way our vision works and the fact that our eyes perceive objects based on their angular size. The closer we are to an object, the larger its angular size appears to us. However, it is important to note that the actual physical size of the object remains the same regardless of the viewing distance.
What describes a light- year? is it the distance that light will travel in a year in a vacuum, total amount of light energy earth revolves in a year, the time is takes light to travel between the sun and earth, or a year a low-gravity planets like mercury
A light-year is the distance that light will travel in a vacuum over the course of one year. It is a unit of measurement used in astronomy to describe vast distances in space. Light travels at a speed of about 299,792 kilometers per second, so in one year, it can cover a distance of approximately 9.46 trillion kilometers (or about 5.88 trillion miles).
which statement about the movement of the sun and stars is correct? is it they move from north to the south across the sky each day, they move from east to west across the sky each day, they move from west to east across the sky each day, they move from south to north across the sky each day
The correct statement about the movement of the sun and stars is that they move from east to west across the sky each day. This apparent motion is caused by the rotation of the Earth on its axis from west to east.
how do ancient Greek stories explain Scorpius and Orion being in the sky at different times of the year
In ancient Greek mythology, the movement of Scorpius and Orion in the sky at different times of the year is explained through a story involving Artemis, the goddess of the hunt, and her giant brother Orion.
According to the myth, Orion was a skilled hunter who boasted that he could kill any animal on Earth. This angered the Earth goddess Gaia, who sent a giant scorpion to challenge Orion. During their epic battle, both Orion and the scorpion were fatally wounded.
Artemis, who was also in love with Orion, was devastated by his death. To honor him, she asked Zeus, the king of the gods, to place Orion in the sky as a constellation. However, Artemis also wanted to protect Orion from the scorpion that had killed him. Thus, Zeus placed Scorpius in the opposite part of the sky, so that the two constellations can never be seen in the sky together.
As a result, during certain times of the year, Scorpius rises in the sky during the nighttime, while Orion sets below the horizon. And during other times, it is Orion that rises while Scorpius sets, ensuring that the two mythical figures are separated in the heavens.
The main problem being solved by the Hubble Space Telescope is the bending of starlight by the Earth's atmosphere. This phenomenon is known as atmospheric distortion or atmospheric turbulence. When light from distant stars passes through the Earth's atmosphere, the varying density and temperature of the air causes the light to bend and blur. This distortion makes it challenging to obtain clear and detailed images of celestial objects.
To overcome this problem, the Hubble Space Telescope was designed to orbit above the Earth's atmosphere, in a location called low Earth orbit. By observing from above the atmosphere, Hubble avoids the atmospheric turbulence and is able to capture incredibly sharp and high-resolution images of stars, galaxies, and other cosmic objects. The images taken by Hubble have led to numerous groundbreaking discoveries in the field of astronomy.
