Hace 5 días · The mounds are also believed to be some of the first structures dedicated to observational astronomy built by humans in South America. “What is most striking is that they do not show up scattered about, but rather they show up in groups,” explains Dr. César González-García, an astronomer at the Institute of Heritage Sciences in Spain.
Hace 2 días · Galileo has been called the father of observational astronomy, modern-era classical physics, the scientific method, and modern science. [7] Galileo studied speed and velocity , gravity and free fall , the principle of relativity , inertia , projectile motion and also worked in applied science and technology, describing the properties of the ...
Hace 2 días · Observational astronomy is focused on acquiring data from observations of astronomical objects. This data is then analyzed using basic principles of physics. Theoretical astronomy is oriented toward the development of computer or analytical models to describe astronomical objects and phenomena.
Hace 3 días · The proper motions of stars near the centre of our own Milky Way provide strong observational evidence that these stars are orbiting a supermassive black hole. Since 1995, astronomers have tracked the motions of 90 stars orbiting an invisible object coincident with the radio source Sagittarius A*.
Hace 6 días · The construction of the European Southern Observatory’s Extremely Large Telescope (ESO's ELT) has reached an important milestone with the delivery to ESO and shipment to Chile of the first 18 segments of the telescope’s main mirror (M1). Once they arrive in Chile, the segments will be transported to the ELT Technical Facility, at ESO’s ...
Hace 2 días · Astronomy, science that encompasses the study of all extraterrestrial objects and phenomena. Since the late 19th century, astronomy has expanded to include astrophysics, the application of physical and chemical knowledge to an understanding of the nature of celestial objects.
The Observational Cosmology Laboratory conducts research to improve understanding of the origin, evolution and ultimate fate of the universe. Specific issues under investigation include what powered the Big Bang; the size, shape, and matter-energy content of the universe; when the first stars and galaxies appeared and their evolution over ...
