Vertical electrical fields due to lightning in the sub-tropical thunderstorms over the rugged terrain were sensed, recorded, and measured at a hilly station of Kathmandu, Nepal. Various types of lightning electric field signatures have been observed, recorded and analyzed. From the records, the cloud-to-ground discharges were found to be 22.4% and cloud-to–cloud discharge were found to be 58.5% whereas, the unusual events counted 10.4% and rest of the events were found to be 8.7%. The lightning activity may be influenced by the hills and mountains due to which greater number of ground flashes and the density of positive ground flashes were relatively higher in Nepal than other geographical locations. Positive lightning flashes are mainly influenced by tall towers, high mountains, rugged hills and other tall structures. Hence, lightning activity is influenced by the high hills and mountains of Nepal.

In solar system, asteroid belt is the ring shaped disc located between Mars and Jupiter consisting of irregular small bodies called asteroids. Almost half of the mass of the belt lies in four asteroids which are Ceres, Vesta, Pallas and Hygiea. Along with asteroid bodies, bands of dust with particle radii of about few hundred micrometers are also a part of asteroid belt. Total mass of asteroid belt is only 4% of the mass of Earth’s moon. The author has studied the causes of asteroid belt in the solar system and has found out that how the gravitational interaction between the two planets is involved in the formation of asteroid belt and how the gravitationally bound system becomes stable enough to avoid any disturbance in the distances of its astronomical bodies.

In spite of enormous advances in Electrical and Aerospace Engineering , Satellite and Space developments we are happy to declare our Euro SatComm 2020, Satellite Expo and Wireless Conference'' which is scheduled on February 12-13, 2020 at Paris, France.

The Global Conference on Satellite & Space Missions is an event that aims to explore the ways to innovate in the field of EEE & Engineering and to find new Technological developments at London, UK on 15 and 16, July 2020. The Satellite Conference will serve as a platform to bring together leading Scientists with different scientific developments in Satellite & Space Missions, Spacecraft, Astronomy, Remote Sensing Satellites, Earth Science, Space Exploration, and Aerospace & Mechanical Engineering.

Conferences Series LLC take great pleasure in inviting the scientific community across the globe to the 4th International Conference on Astronomy and Space Technology during May 20-21, 2020 at Berlin, Germany. This meeting will explore advances in the Astronomy and Space Technology.

The title indicates, our view of Astrophysics is based on the premise that “It is often stated that of all the theories proposed in this century, the silliest is quantum theory. In fact, some people say that the only thing that quantum theory has going for it is that it is unquestionably correct”. We invite all the participants throughout the world to join us for the upcoming “3rd Annual Congress on Astronomy, Astrophysics and Space Science” presented in Munich, Germany, during 16-17 October 2020, working with the theme: Big Ideas and Thoughts of Astronomy, Astrophysics and Space Science will address this topic, presenting by speakers from all over the world as announced in an earlier editorial.

The small satellite market was valued at $3,632.4 million in 2018, and is expected to reach $15,686.3 million by 2026, registering a CAGR of 20.1% from 2018 to 2026. Small Satellites are satellites with masses lower than 500 kg. This small satellite market analysis projects the market to grow at a significant CAGR of 14.15% by value and 14.28% by volume, during the forecast period from 2019 to 2030. North America dominated the global small satellite market at a share in 2018. Europe, including the major countries such as the U.K., Germany, Denmark, and Russia, are the most prominent countries for the small satellite market. During the forecast period, the Rest-of-the-World is anticipated to grow at the highest rate due to the increasing requirement of the affordable satellite to attain sustainability.

After the successful completion of the Quantum Physics 2019 conference series, we are pleased to welcome you to the “6th International conference on Quantum Physics and Nuclear Engineering." The congress is scheduled to take place on July 27-28, 2020 in the beautiful city of London, UK. This 2020 Quantum Physics Conference will give you exemplary experience and great insights in the field of research.

Astronomy is one amongst the oldest fields of science. It deals with the study of the Universe and of the objects like sun, moon, stars, planets, comets, gas, galaxies, gas, dirt and alternative non-earthy bodies. It’s additionally a multidisciplinary subject that deals with the study of science with physics, chemistry, arithmetic, engineering science, earth science and biology. Astronomy is essentially a data-based science instead of an experimental one.
