The Sloan Digital Sky Survey or SDSS is a major multi-spectral imaging and spectroscopic redshift survey using a dedicated 2.5-m wide-angle optical telescope at Apache Point Observatory in New Mexico, United States. The project began in 2000 and was named after the Alfred P. Sloan Foundation, which contributed significant funding.
Optical Telescope Element. Spacecraft ( Bus and Sunshield) James Webb Space Telescope mission logo. The James Webb Space Telescope ( JWST) is a space telescope designed to conduct infrared astronomy. Its high-resolution and high-sensitivity instruments allow it to view objects too old, distant, or faint for the Hubble Space Telescope. [10]
GLASS-z12. GLASS-z12 (formerly known as GLASS-z13) is a Lyman-break galaxy discovered by the Grism Lens-Amplified Survey from Space (GLASS) observing program using the James Webb Space Telescope 's NIRCam in July 2022. [8] [9] Spectroscopic observations of GLASS-z12 by the Atacama Large Millimeter Array (ALMA) in August 2022 confirmed that the ...
Edwin Hubble was born to Virginia Lee Hubble (née James) (1864–1934) [14] and John Powell Hubble, an insurance executive, in Marshfield, Missouri, and moved to Wheaton, Illinois, in 1900. [15] In his younger days, he was noted more for his athletic prowess than his intellectual abilities, although he did earn good grades in every subject ...
Galaxy formation is hypothesized to occur from structure formation theories, as a result of tiny quantum fluctuations in the aftermath of the Big Bang. The simplest model in general agreement with observed phenomena is the Lambda-CDM model —that is, that clustering and merging allows galaxies to accumulate mass, determining both their shape ...
Interacting galaxies ( colliding galaxies) are galaxies whose gravitational fields result in a disturbance of one another. An example of a minor interaction is a satellite galaxy disturbing the primary galaxy's spiral arms. An example of a major interaction is a galactic collision, which may lead to a galaxy merger .
Andrea M. Ghez. Andrea Mia Ghez (born June 16, 1965) is an American astrophysicist, Nobel laureate, and professor in the Department of Physics and Astronomy and the Lauren B. Leichtman & Arthur E. Levine chair in Astrophysics, at the University of California, Los Angeles. [1] Her research focuses on the center of the Milky Way galaxy.
Galaxy. NGC 4414, a typical spiral galaxy in the constellation Coma Berenices, is about 55,000 light-years in diameter and approximately 60 million light-years from Earth. A galaxy is a system of stars, stellar remnants, interstellar gas, dust, and dark matter bound together by gravity.
