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 ...

The month of February brought some unbelievably exciting discoveries in the study of space, and with it even more out of this world images. Most notably, scientists detected a "chirp" from ...
December 16 – The Beethoven Burst (GRB 991216) is one of the most powerful detected Gamma-ray bursts. NASA loses two Mars probes, the Mars Climate Orbiter and the Mars Polar Lander. The Subaru 8.3 m and Gemini North 8.1 m reflecting telescopes open at the Mauna Kea Observatory in Hawaii. The Cetus Dwarf galaxy is discovered.
9 May: A cubic millimetre of the human brain is mapped at nanoscale resolution by a team at Google 30 May: NASA reports the discovery of the most distant known galaxy. 9 May. A record annual increase in atmospheric CO 2 is reported from the Mauna Loa Observatory in Hawaii, with a jump of 4.7 parts per million (ppm) compared to a year earlier. [285]
Space exploration, like its classical form astronomy, is one of the main sources for space science. While the observation of objects in space, known as astronomy , predates reliable recorded history , it was the development of large and relatively efficient rockets during the mid-twentieth century that allowed physical space exploration to ...
