    Abstract The researchers have developed a machine learning model called the Stability of Planetary Orbital Configurations Klassifier (SPOCK). This model can characterize thousands of planetary systems at once. SPOCK is much quicker and more efficient than former models. The former models based predictions off of angular momentum deficit and chaos. Researchers input the eccentricity of planet orbits, radial velocity, and transit duration into SPOCK. Then, SPOCK can predict how stable the planetar...

    Abstract The density of the interstellar medium, the matter and radiation that exists between stars in space, determines where stars form and release energy and drives how galaxies change over time. Variations in this density result from how gases move (gas motion), but the nature of this motion across space and in different galaxies is unknown. Dense gas that forms stars is most likely formed by a combination of gas instability, collision, and turbulence. However, it is still difficult to under...

    AbstractThere are a small number of multiplanet systems known today. This study detected a second planet around the star TYC 8998-760-1. This is the first multiplanet system to be directly imaged around a young star, and is ideal to continue imaging because the two planets are far apart. There is also reason to believe that a third, unseen planet is also in orbit around TYC 8998-760-1.AimsThis study aims to report the findings of a newly identified gas giant planet that orbits the star TYC 8998-...

    Abstract     This paper uses baryonic matter which is composed of baryons. Baryons include subatomic particles such as protons, neutrons, and all objects composed of them (atomic nuclei), however it excludes leptons and electrons. This paper uses baryonic matter and a mathematical relation known as the Tully-Fisher relation (bTFR) to better calculate the H0, which is the hubble constant. The hubble constant is a number that can change with time, but is the ratio of the velocity to the distance o...

    Abstract Despite the limited images of lightning on Jupiter, many photos have been used to determine the properties of lightning on Jupiter. For the first time, very high resolution photos have been taken of lightning, which show a higher flash rate, faster flash duration, and more accurate HWHM values. Same of the lightning has an origin higher than liquid water exists, which causes scientists to reconsider the known mechanism of lightning generation. Aims This study aims to discuss the meanin...
