The amount of light energy gathered by a telescope is determined by the size of its objective lens. The larger the lens’s surface area, the better the telescope can observe faint luminous objects. When light passes through the objective lens of a refractor telescope, it is refracted and forms an image of the object in…

Saturn, the sixth planet in our solar system, is known for its unique internal structure. It is the second largest planet, after Jupiter, in terms of size among all the planets orbiting the Sun. Scientists categorize Saturn as a gas giant, a type of planet composed mainly of hydrogen and helium. The planet was named…

In order to comprehend the correlation between the Earth’s motion and natural phenomena, it is essential to ascertain the speed at which our planet orbits in space. Having knowledge of this value also enables us to make predictions about the future of this celestial body. The Earth’s orbital path Our planet traverses an elliptical trajectory…

Sunspots are dark regions on the surface of the Sun that have a lower temperature compared to the surrounding areas of the photosphere, with a difference of about 1500 K. These spots can be observed on the Sun’s disk using optical instruments, and sometimes even with the naked eye, especially when they are large. They…

Situated between the orbits of Mercury and Earth, Venus has become a subject of extensive exploration due to its prime position for observations. What intriguing details can we uncover about this celestial body known as the “morning star”? Similar to Earth Venus is often referred to as the “sister planet” of Earth due to its…

Mars and Venus are the two planets that resemble Earth the most. Both can be seen without a telescope and are among the brightest objects in the night sky. Venus is located at an average distance of just 108 million kilometers from the Sun, whereas Mars is much farther away at 228 million kilometers. Venus…

In the distant future, it is highly probable that humanity, or a portion of it, will be required to depart from Earth. This necessity may arise due to factors such as overpopulation, natural disasters, or the depletion of natural resources. However, simply leaving our current home and venturing into space in search of a new…

When it comes to telescopes, there are two important concepts to consider: the maximum useful magnification and the magnification achieved with a specific eyepiece. The maximum useful magnification refers to the optimal level at which the telescope’s optics perform. Going beyond this limit will result in a decrease in image quality. To calculate the maximum…

According to Obi-Wan Kenobi, the force is responsible for holding the galaxy together. The same principle can be applied to gravity. In reality, gravity enables us to walk on the surface of the Earth, allows the Earth to orbit around the Sun, and permits the Sun to orbit around the supermassive black hole located at…

Greetings, esteemed hubra community! As promised following last week’s piece on string theory, today we will endeavor to unveil the enigma and delve into the latest advancements in cosmology. Together, we will explore the arduous journey scientists have embarked upon and discover their ultimate destination in their quest to elucidate the genesis, existence, and fate…

Stellar magnitude, also known as visible stellar magnitude, is a dimensionless numerical value used to describe the brightness of celestial objects, primarily stars, as seen from the observer’s location. It takes into account both the amount of light emitted by the object and its distance from the observer. Stellar magnitude serves as a metric for…

As humans ventured out to explore their planet, they needed various units of measurement for distances and lengths. Initially, these measurements were inconsistent because different cultures had their own unique ways of measuring. However, in 1791, French scientists introduced a universal unit of length that is still widely used today – the meter (derived from…

Astronomers recently unveiled a fresh and remarkably detailed snapshot of the central area of the Milky Way galaxy. This captivating image spans an impressive distance of approximately 600 light-years. Discover the significance behind this extraordinary image for scientists and researchers. What is depicted in the new image? The new image showcases the Arca cluster, which…

Before discussing the objects that can be observed through a telescope, it is important to understand some basic information about these instruments and their different types. To enjoy the view of the night sky from the comfort of your own home, it is essential to select the appropriate optical device. The price range for a…

A supernova is essentially an explosion of a star and is the most powerful event that can be witnessed in outer space. Where do supernova remnants appear? Supernovae are often visible in other galaxies. However, in our own Milky Way, it is a rare occurrence to witness a supernova due to the obstruction caused by…

Announcements regarding the potential discovery of habitable planets do not generate much excitement. Planets with atmospheres are quite common, with over two thousand already identified, and most of them bear striking similarities to our own Earth. However, when it comes to finding planets that closely resemble Earth, we are limited to only a handful. Nevertheless,…

In the modern era, with the abundance of artificial lighting in cities, urban dwellers are deprived of the opportunity to witness the breathtaking sight of the Milky Way. This celestial phenomenon, visible only during certain times of the year, can only be observed far away from densely populated areas. In our particular region, it reaches…
