The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
Timeline of stellar astronomy. 1200 BC — Chinese star names appear on oracle bones used for divination. 134 BC — Hipparchus creates the magnitude scale of stellar apparent luminosities; 185 AD — Chinese astronomers become the first to observe a supernova, the SN 185
c. 150 BCE – According to Strabo (1.1.9), Seleucus of Seleucia is the first to state that the tides are due to the attraction of the Moon, and that the height of the tides depends on the Moon's position relative to the Sun. [30] c. 150 BCE – Hipparchus uses parallax to determine that the distance to the Moon is roughly 380,000 km (236,100 ...
The following is a list of particularly notable actual or hypothetical stars that have their own articles in Wikipedia, but are not included in the lists above. BPM 37093 — a diamond star Cygnus X-1 — X-ray source
This is a timeline of Solar System exploration ordering events in the exploration of the Solar System by date of spacecraft launch. It includes: It includes: All spacecraft that have left Earth orbit for the purposes of Solar System exploration (or were launched with that intention but failed), including lunar probes .
The most powerful telescope to be launched into space has made history by detecting a record number of new stars in a distant galaxy. NASA's James Webb Space Telescope, history's largest and most ...
By applying new ideas from subatomic physics, Subrahmanyan Chandrasekhar predicts that the atoms in a white dwarf star of more than 1.44 solar masses will disintegrate, causing the star to collapse violently. In 1933, Walter Baade and Fritz Zwicky describe the neutron star that results from this collapse, causing a supernova explosion.
HD 114762 b was once considered as the first discovered exoplanet. Found in 1989 by a team led by David Latham, it is now known to be a red dwarf star. [5] In 1991 it was reported an exoplanet 10 times the mass of Earth was discovered around the pulsar, PSR B1829-10. [6]
