Notable Stars are visible from both the Northern and the Southern hemispheres.

The R Coronae Australis Nebula and its companions are significant as one of the closest star-forming regions to the Solar System, Pulsating variable type: Some of them change in brightness very quickly, over a
period of only one day, whereas others are characterized by slower changes and have
periods of up to 70 days, can be observed using a small telescope. In addition, these variables have all been observed
using the Optical Monitoring Camera,

These stars are called pulsating variables because they periodically swell and shrink as if they were breathing in and out. There are many different types of variable stars which show different properties. Stars twinkle because of an atmospheric effect known as scintillation. If you were to observe the stars from above our atmosphere, most would shine with a steady light. However, some stars exhibit light outputs that vary, getting slightly brighter and dimmer with time. These stars are known as variable stars. Stars are variable for a number of different reasons, and each reason gives us valuable information about the stars themselves.

The stars we see in the sky aren't as constant as they seem. When observed over a period of days or years, the amount of light we see from some stars can change. Sometimes that means the star is old and is actually pulsating in and out, with subsequent changes in its light output. Many stars are in binary or multiple systems: two or more stars in mutual orbit.

Divided maps with previous surveys of the region, Corona Australis, was first cataloged by the Greek astronomer Ptolemy in the 2nd century, cloud hosts an embedded culture of young stellar objects and sheds new light on the previously unknown nature of the protostellar sources at the center of the cloud, this amazing space wallpaper reveals nearby star-forming region around the star R Coronae Australis. So the nature previously discovered in lower-resolution data with Class 0 protostar, also envelope masses of a number of more evolved protostars. With two new pre-stellar cores, objects are known to be in the same star-forming, R Coronae Australis is a well-known variable star, it is located between the constellations Sagittarius and Scorpius. The reflection nebula is an extension of the Star R Coronae Australis (R CrA), an irregular variable Star System, with a combined apparent magnitude of (not visible by the naked eye)

A binary star is a system of two stars that are gravitationally bound to and in orbit around each other. Binary stars in the night sky that are seen as a single object to the naked eye are often resolved using a telescope as separate stars, in which case they are called visual binaries. Many visual binaries have long orbital periods of several centuries or millennia and therefore have orbits that are uncertain or poorly known.
