To take pictures of other galaxies, astronomers use telescopes equipped with sensitive cameras to capture light emitted by the distant galaxies. These telescopes are often placed in space or in remote locations to minimize interference from Earth's atmosphere and light pollution. The images captured are then processed and analyzed to study the properties and characteristics of the galaxies.
No. Elliptical galaxies are some of the oldest galaxies.They are also called early galaxies. The elliptical galaxies are made of low massed stars, a sparse interstellar medium and very low star forming characteristics.
Galaxies in the universe have different names based on their shape and structure. Some common types of galaxies include spiral galaxies, elliptical galaxies, and irregular galaxies. Each type has its own unique characteristics and features.

Spiral galaxies, barred spiral galaxies, elliptical galaxies, and irregular galaxies
The possessive form of "galaxies" is "galaxies'". It indicates that something belongs to or is associated with multiple galaxies.
Galaxies are classified based on their shape, size, and structure. The main types of galaxies are spiral, elliptical, and irregular. Spiral galaxies have arms that spiral out from a central core, while elliptical galaxies are more rounded in shape. Irregular galaxies do not have a distinct shape. Additionally, galaxies can be classified based on their size and the presence of a central bulge or bar.
Astronomers group galaxies into three types based on their characteristics: spiral galaxies have arms that spiral out from a central bulge, elliptical galaxies are oval-shaped with no distinct structure, and irregular galaxies have a chaotic and asymmetrical shape.
Elliptical galaxies are sometime called dwarf galaxies.
15 Galaxies? There are over 1,000,000,000 galaxies possibly more.
Elliptical galaxies are generally round or oval in shape, lacking the distinctive spiral arms seen in spiral galaxies. They typically have a smooth and featureless appearance, with older star populations and little ongoing star formation. Elliptical galaxies also tend to be more massive and contain mainly older stars.
