This is a list of extraterrestrial beings that have been reported in close encounters, claimed or speculated to be associated with unidentified flying objects (UFOs) (not to be confused with the meaning of the term "alien species" in the biological science of ecology). [1]
1995 — First detection of small-scale structure in the cosmic microwave background. 1995 — Hubble Deep Field survey of galaxies in field 144 arc seconds across. 1998 — The 2dF Galaxy Redshift Survey maps the large-scale structure in a section of the Universe close to the Milky Way. 1998 — The Hubble Deep Field South is compiled.
UNCOVER-z13. UNCOVER-z13 is a high-redshift Lyman-break galaxy discovered by the James Webb Space Telescope (JWST) [1] during NIRCam imaging for the JWST Ultradeep NIRSpec and NIRCam Observations before the Epoch of Reionization (UNCOVER) project [2] on November 14, 2023. UNCOVER-z13 is within Abell 2744 supercluster in the constellation Sculptor.
The study of galaxy formation and evolution is concerned with the processes that formed a heterogeneous universe from a homogeneous beginning, the formation of the first galaxies, the way galaxies change over time, and the processes that have generated the variety of structures observed in nearby galaxies. Galaxy formation is hypothesized to ...
Most films listed here were distributed in the United States, unless otherwise noted, by Walt Disney Studios' theatrical distribution unit; currently known as Walt Disney Studios Motion Pictures, formerly known as Buena Vista Distribution Company/Buena Vista Film Distribution Company (until 1987) and Buena Vista Pictures Distribution (1987–2007).
Size (left) and distance (right) of a few well-known galaxies put to scale. The following is a list of notable galaxies.. There are about 51 galaxies in the Local Group (see list of nearest galaxies for a complete list), on the order of 100,000 in the Local Supercluster, and an estimated 100 billion in all of the observable universe.
The Magellanic Clouds ( Magellanic system[ 2][ 3] or Nubeculae Magellani[ 4]) are two irregular dwarf galaxies in the southern celestial hemisphere. Orbiting the Milky Way galaxy, these satellite galaxies are members of the Local Group. Because both show signs of a bar structure, they are often reclassified as Magellanic spiral galaxies.
Galaxy is a scientific workflow system. These systems provide a means to build multi-step computational analyses akin to a recipe. They typically provide a graphical user interface [ 6] for specifying what data to operate on, what steps to take, and what order to do them in. Galaxy is also a data integration platform for biological data.
