Astrometry is a branch of astronomy that involves precise measurements of the positions and movements of stars and other celestial bodies. It provides the kinematics and physical origin of the Solar System and this galaxy, the Milky Way.
James Ephraim Lovelock was an English independent scientist, environmentalist and futurist. He is best known for proposing the Gaia hypothesis, which postulates that the Earth functions as a self-regulating system.
The Gaia hypothesis, also known as the Gaia theory, Gaia paradigm, or the Gaia principle, proposes that living organisms interact with their inorganic surroundings on Earth to form a synergistic and self-regulating, complex system that helps to maintain and perpetuate the conditions for life on the planet.
Gaia is a space observatory of the European Space Agency (ESA), launched in 2013 and expected to operate until 2025. The spacecraft is designed for astrometry: measuring the positions, distances and motions of stars with unprecedented precision, and the positions of exoplanets by measuring attributes about the stars they orbit such as their apparent magnitude and color. The mission aims to construct by far the largest and most precise 3D space catalog ever made, totalling approximately 1 billion astronomical objects, mainly stars, but also planets, comets, asteroids and quasars, among others.
Mary Beatrice Midgley was a British philosopher. A senior lecturer in philosophy at Newcastle University, she was known for her work on science, ethics and animal rights. She wrote her first book, Beast and Man (1978), when she was in her late fifties, and went on to write over 15 more, including Animals and Why They Matter (1983), Wickedness (1984), The Ethical Primate (1994), Evolution as a Religion (1985), and Science as Salvation (1992). She was awarded honorary doctorates by Durham and Newcastle universities. Her autobiography, The Owl of Minerva, was published in 2005.
The Sculptor Dwarf Galaxy is a dwarf spheroidal galaxy that is a satellite of the Milky Way. The galaxy lies within the constellation Sculptor. It was discovered in 1937 by American astronomer Harlow Shapley using the 24-inch Bruce refractor at Boyden Observatory. The galaxy is located about 290,000 light-years away from the Solar System. The Sculptor Dwarf contains only 4 percent of the carbon and other heavy elements in our own galaxy, the Milky Way, making it similar to primitive galaxies seen at the edge of the universe.
Zeta Andromedae is a star system in the constellation Andromeda. It is approximately 189 light-years from Earth.
Chi Andromedae is the Bayer designation for a star in the northern constellation of Andromeda. It has an apparent visual magnitude of +5.01, which is relatively faint for a naked-eye star. Based upon parallax measurements made during the Gaia mission, Chi Andromedae is located around 264 light-years from Earth.
107 Aquarii is a double star in the equatorial constellation of Aquarius. 107 Aquarii is the Flamsteed designation, although it also bears the Bayer designation i2 Aquarii. The pair have an angular separation of 6.787 arcseconds. They have a combined apparent visual magnitude of +5.305, with individual magnitudes of 5.72 and 6.72. The annual parallax shift measured for the two components is 16.1 mas and 20.0 mas respectively, although with significant statistical margins of error and flags for potential unreliability of both values. This indicates the system may be at a distance of 160–200 light-years from Earth.
49 Aquarii, abbreviated 49 Aqr, is a star in the zodiac constellation of Aquarius. 49 Aquarii is its Flamsteed designation. It is a dim star with an apparent visual magnitude of 5.53. The distance to 49 Aqr, as determined from its annual parallax shift of 12.28 mas, is 266 light years. It is moving closer to the Earth with a heliocentric radial velocity of −13 km/s.
34 Boötis is a single variable star in the northern constellation Boötes, located around 700 light years away from the Sun. At that distance, the visual magnitude of the star is diminished by an extinction of 0.49±0.02 due to interstellar dust. It has the variable star designation W Boötis; 34 Boötis is the Flamsteed designation. This object is visible to the naked eye as a faint, red-hued star with a baseline apparent visual magnitude of 4.80. It is moving away from the Earth with a heliocentric radial velocity of +5.6 km/s.
Gaia, Inc., formerly Gaiam, is an American alternative media video on demand streaming service founded by Jirka Rysavy.
Sustainability science first emerged in the 1980s and has become a new academic discipline. Similar to agricultural science or health science, it is an applied science defined by the practical problems it addresses. Sustainability science focuses on issues relating to sustainability and sustainable development as core parts of its subject matter. It is "defined by the problems it addresses rather than by the disciplines it employs" and "serves the need for advancing both knowledge and action by creating a dynamic bridge between the two".
In Greek mythology, Gaia, also spelled Gaea, is the personification of the Earth. Gaia is the ancestral mother—sometimes parthenogenic—of all life. She is the mother of Uranus (Sky), from whose sexual union she bore the Titans, the Cyclopes, and the Giants; as well as of Pontus (Sea), from whose union she bore the primordial sea gods. Her equivalent in the Roman pantheon was Terra.
GJ 3379 is the nearest star in the Orion constellation, located at a distance of 17 light years from the Sun based on parallax. It is a single star with an apparent visual magnitude of +11.31 and an absolute magnitude of +12.71, therefore, the star is not visible with the naked eye. It is positioned in the upper left part of the Orion constellation, to the SSE of Betelgeuse. This star is drifting further away with a radial velocity of +30.0 kilometers per second. In the past, this star had a relatively close encounter with the Solar System. Some 161,000±6,000 years ago, it achieved a minimum distance of 4.08 ± 0.20 ly (1.25 ± 0.06 pc).
6 Persei is a binary star system in the northern constellation of Andromeda. It is faintly visible to the naked eye with an apparent visual magnitude of 5.29. The system is located 182 light years from Earth, as determined from its annual parallax shift of 17.9 mas. It is moving further away with a heliocentric radial velocity of +42 km/s. The system has a relatively high rate of proper motion, traversing the celestial sphere at the rate of 0.386 arcsecond/year.
LS Canis Majoris is an eclipsing binary star located around 1,510 light years from Earth in the constellation Canis Major. Its apparent magnitude ranges from 5.63 to 5.79. The orbital period of binary pair and the period of light variation is 70.048 days.
TW Andromedae is an eclipsing binary star, classified also as an Algol variable star, in the constellation Andromeda. Its brightness varies with a period of 4.12 days, and has a typical brightness of magnitude 8.98 but decreasing down to a magnitude of 11.04 during the main eclipse.
Gliese 49 is a star in the northern constellation of Cassiopeia. Visually, it is located 106 arcminutes north of the bright star γ Cassiopeiae. With an apparent visual magnitude of 9.56, it is not observable with the naked eye. It is located, based on the reduction of parallax data of Gaia, 32.1 light-years away from the Solar System. The star is drifting closer to the Sun with a radial velocity of −6 km/s.
ROXs 12 is a binary system of pre-main-sequence stars. It belongs to the Rho Ophiuchi cloud complex. The surface temperature of the primary star is 3900±100 K. ROXs 12 is much younger than the Sun with an age of 7.6+4.1
−2.5 million years.
