Adaptive optics were developed to overcome the blurring of images caused by atmospheric turbulence when observing distant objects in space. By rapidly adjusting the shape of a mirror in a telescope to compensate for the distortions introduced by the atmosphere, adaptive optics improve the clarity and resolution of astronomical images.
Astronomers use radio telescopes, infrared telescopes, and space-based telescopes to map the shape of the Milky Way. They measure the positions and motions of stars, gas, and dust to create a three-dimensional map of our galaxy.
Scientists use telescopes, specifically large ground-based telescopes and space telescopes like the Hubble Space Telescope, to study Eris. These telescopes allow them to observe Eris' size, shape, surface features, and composition.
Plane mirrors don't form real images. Concave mirrors and convex lenses do. Without a real image, you have nothing to expose film to, nothing to project onto a screen, nothing to capture on a CCD or vidicon, and nothing to look at with an eyepiece.
It is generally more challenging to produce large mirrors for telescopes compared to large lenses because mirrors need to be ground and polished to a very high precision to avoid distortions and aberrations in the images produced. Lenses can also suffer from similar issues, but the methods to correct them are different and often less complex. Additionally, mirrors are usually easier to support and maintain their shape compared to large lenses.
Adaptive optics systems use a combination of wavefront sensors and deformable mirrors to relay information to a computer for adjusting a telescope's mirror. The wavefront sensors detect distortions in the incoming light caused by atmospheric turbulence, while the computer processes this data to calculate the necessary adjustments. The deformable mirror then changes its shape in real-time to correct these distortions, resulting in clearer images. This technology enhances the resolution of telescopes, allowing for more detailed observations of celestial objects.
A parabolic mirror with a concave shape focuses incoming light rays to a single point called the focal point. This results in a concentrated and intensified reflection of light, making the mirror useful for applications such as telescopes and satellite dishes.
A multi-mirror telescope uses multiple smaller mirrors to gather and focus light, whereas a traditional single-mirror telescope uses one large mirror. This design allows multi-mirror telescopes to have a larger aperture and better image resolution. Additionally, multi-mirror telescopes can be more compact and cost-effective compared to single-mirror telescopes.

no concave mirror is in shape of concave mirror
The atmosphere is a chaotic mixture of gases and vapours. The turbulences in the atmosphere distort the paths of light-rays falling on the Earth from distant celestial objects, thereby distorting the images they form in telescopes.To compensate, the more advanced modern telescopes use lasers to measure the current distortion in the atmosphere directly in the path of the telescope, and use those measurements to change the shape of the mirror in the telescope from millisecond to millisecond, thereby cancelling much of those distortions.
A globe is the representation of Earth that would not have any distortions, as it accurately represents the three-dimensional shape of our planet.

A globe would be the most accurate representation of Earth without distortions as it shows the planet in three dimensions, preserving the true shape of landmasses and distances between them.
Parallel light rays hitting a concave mirror will converge to a single focal point after reflection, due to the mirror's inward or converging shape. The focal point is located on the principal axis of the mirror, halfway between the mirror's center and the vertex. This property of concave mirrors is used in applications like focusing light in telescopes and for creating images in reflective devices.
