The Solar System is comprised of the Sun and the objects that circle it, all of which are held together by gravity. In terms of mass and size, the four gas and ice giants and four terrestrial planets are the biggest of the worlds that circle the Sun directly, followed by an unknown number of dwarf planets and an uncountable number of minor Solar Systems components.
The Milky Way galaxy contains our Solar System, and its name refers to the galaxy’s appearance from Earth: a hazy band of light visible in the night sky formed by stars that cannot be distinguished individually by the naked eye. The Milky Way is a spiral galaxy that includes our Solar System.
There are eight planets in the solar system: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. These are the known planets, but NASA over the years discovered a lot more, that is a million light-years away, but still a great scientific achievement knowing they exist.
Planet TIC 172900988 b
A worldwide first time research team headed by Veselin B. Kostov of NASA’s Goddard Space Flight Center found the transiting circumbinary planet, TIC 172900988 b, with the help of NASA’s Goddard Space Flight Center.
One of the most active Jupiters in the solar system, TOI-1518 b, has been verified by another multinational team, this time headed by Yale University’s Samuel H.C. Cabot, using data open sans, from the TESS spacecraft. A newly found planet with a circumference about equal to that of Jupiter is part of a system that is a sight to see.
The planet revolves around two stars and, as seen from Earth, crosses the faces of both of these stars. Astronomers were treated to a spectacular display by this system, which saw the two stars undergo a total of three eclipses, as the planet made its path over one star and then across the other for greater distances a few days later.
Planet TOI 700 d
NASA’s Transiting Exoplanet Survey Satellite (TESS) thanks to a transit method from the black hole, has discovered a new planet. The first Earth-sized planet in its star’s habitable zone, which is the range of distances where conditions may be just right to allow the presence of liquid water on the planet’s surface. The planet was discovered in the habitable zone by NASA’s Transiting Exoplanet Survey Satellite (TESS).
Scientists used NASA’s Spitzer Space Telescope to confirm the discovery, which they named TOI 700 d. They also created a model of the planet’s possible habitats to assist influence future studies for hydrogen atoms in the long orbit and tight orbits. TOI 700 d is one of just a handful of Earth-sized planets that have been identified in a star’s habitable zone thus far, according to NASA.
Other worlds found by NASA’s Kepler Space Telescope include six planets in the TRAPPIST-1 system and other worlds identified by the Hubble Space Telescope. According to Paul Hertz, head of the astrophysics division at NASA Headquarters in Washington, “TESS was developed and launched precisely for the purpose of discovering Earth-sized planets circling nearby stars.”
The fun facts are that larger telescopes in space and on the ground can best see outer planets orbiting close stars, which makes it easier to track them. Also, thousands of neutron star objects make it a bit difficult to track the surface temperatures and deliver intriguing results, however, that is also manageable.
Thanks to months of data and planetary transits tracking the prime candidate and the new giant was discovered. The discovery of TOI 700 d is a significant scientific breakthrough for TESS. In addition to confirming the size and presence of habitable zones on Earth with Spitzer, the mission has scored another victory as its scientific activities come to a close in January.”
Planet TOI-674 b
This investigation of water vapor on TOI-674 b was conducted by a worldwide team of scientists headed by Jonathan Brande of the University of Kansas and has been submitted to an academic publication. In addition to experts from the NASA Ames Research Center, IPAC and other research institutes at Caltech were among those in attendance.
According to Rosanne Di Stefano, with its slightly larger size than Neptune and circling a red dwarf star some 150 light-years distant, this newly discovered planet is welcomed into an exclusive group of exoplanets, which are planets that circle other stars and have been shown to contain water vapor in their atmospheres.
There are still many unanswered problems, such as how much water vapor is there in its atmosphere. However, the atmosphere of TOI-674 b is significantly more easily seen than the atmospheres of many other exoplanets, making it an ideal candidate for further exploration.
One of the more interesting giant planet and exoplanet candidates. A second look on the 674 b showed that the discovery of exoplanets is a great addition to recent breakthroughs, which were mostly based on a small star.
Planet TOI-1231 b
A large, international team of astronomers led by Dr. Jennifer Burt, an exoplanet researcher at NASA’s Jet Propulsion Laboratory in Southern California, and Professor Diana Dragomir, an exoplanet researcher at the University of New Mexico, announced the discovery of TOI-1231 b in a new paper based on data from the Transiting Exoplanet Survey Satellite.
NASA’s Exoplanet Archive has been updated to include the finding. A planet 90 light-years distant from Earth has a strange resemblance to our own Neptune — that is, it is a gaseous globe with a potentially rich atmosphere that is ready for investigation and exploration.
The planet is more than three and a half times the size of Earth and is very hot by Earthly standards, with temperatures reaching 134 degrees Fahrenheit (57 Celsius). It is considered to be one of the “coolest,” comparably tiny planets discovered to date, and it is in a great location for the components of its atmosphere to be plucked apart by space telescopes, according to scientists.
Planet GJ 1132 b
Scientists working with NASA’s Hubble Space Telescope have discovered evidence in the planetary systems that a planet circling a distant star may have lost its atmosphere but developed a second one as a result of volcanic activity may have been discovered.
Scientists believe that the planet GJ 1132 b began life as a gaseous globe with a thick hydrogen blanket of atmosphere before evolving into what it is now. Due to the extreme radiation from the hot, young star around which it circles, it is thought that this so-called “sub-Neptune” began life as a planet many times the diameter of Earth, but swiftly lost its primordial hydrogen and helium atmosphere as a result.
The key facts are that in a very short amount of time, such an orbiting planet would be reduced to a bare core around the first star and the size of the Earth’s core. Things started to become intriguing for host stars at that point.
