Earendel (star)
WHL0137-LS, also known as Earendel, is a star in the constellation of Cetus. Discovered in 2022 by the Hubble Space Telescope, it is the earliest and most distant known star, at a comoving distance of . The previous furthest known star, MACS J1149 Lensed Star 1, also known as Icarus, at a comoving distance of , was discovered by Hubble in 2018. Stars like Earendel can be observed at cosmological distances thanks to the large magnification factors involved, that can exceed 1000. Other stars have been observed through this technique, such as Godzilla. Observation Earendel's discovery by the Hubble Space Telescope was reported on 30 March 2022. The star was detectable due to gravitational lensing caused by the presence of the galaxy cluster WHL0137-08 between it and the Earth, concentrating the light from the star. Computer simulations of the lensing effect suggest that Earendel's brightness was magnified between one thousand and forty thousand times. The dates of Hubble's expo ...

The Sunrise Arc Galaxy With Lensed Star Earendel -b
''The'' () is a grammatical article in English, denoting persons or things that are already or about to be mentioned, under discussion, implied or otherwise presumed familiar to listeners, readers, or speakers. It is the definite article in English. ''The'' is the most frequently used word in the English language; studies and analyses of texts have found it to account for seven percent of all printed English-language words. It is derived from gendered articles in Old English which combined in Middle English and now has a single form used with nouns of any gender. The word can be used with both singular and plural nouns, and with a noun that starts with any letter. This is different from many other languages, which have different forms of the definite article for different genders or numbers. Pronunciation In most dialects, "the" is pronounced as (with the voiced dental fricative followed by a schwa) when followed by a consonant sound, and as (homophone of the archaic pro ...

Old English
Old English (, ), or Anglo-Saxon, is the earliest recorded form of the English language, spoken in England and southern and eastern Scotland in the early Middle Ages. It was brought to Great Britain by Anglo-Saxon settlement of Britain, Anglo-Saxon settlers in the mid-5th century, and the first Old English literature, Old English literary works date from the mid-7th century. After the Norman conquest of 1066, English was replaced, for a time, by Anglo-Norman language, Anglo-Norman (a langues d'oïl, relative of French) as the language of the upper classes. This is regarded as marking the end of the Old English era, since during this period the English language was heavily influenced by Anglo-Norman, developing into a phase known now as Middle English in England and Early Scots in Scotland. Old English developed from a set of Anglo-Frisian languages, Anglo-Frisian or Ingvaeonic dialects originally spoken by Germanic peoples, Germanic tribes traditionally known as the Angles, Sa ...

ScienceAlert
ScienceAlert is an independently run online publication and news source that publishes articles featuring scientific research, discoveries and outcomes. The site was founded in 2004 by Julian Cribb, a science writer, to aggregate research findings from Australian universities, and expanded in 2006 when ex-Microsoft programmer Chris Cassella took on the project of developing the website. It has readership that ranges from 11.5m to 26.5m per month. Science journalist Fiona MacDonald has been CEO since 2017. History Science communicator Julian Cribb founded ScienceAlert in 2004. The website was borne of his “concern at the lack of information available about what Australians and New Zealanders achieve in science.” Chris Cassella, a former programmer for Microsoft, joined the site in order to develop new webtools. He took on this work as part of a Master’s thesis in Science Communication at Australia National University, where Cribb was a professor. Initially, ScienceAlert’ ...

Stellar Spectra
Astronomical spectroscopy is the study of astronomy using the techniques of spectroscopy to measure the spectrum of electromagnetic radiation, including visible light, ultraviolet, X-ray, infrared and radio waves that radiate from stars and other celestial objects. A stellar spectrum can reveal many properties of stars, such as their chemical composition, temperature, density, mass, distance and luminosity. Spectroscopy can show the velocity of motion towards or away from the observer by measuring the Doppler shift. Spectroscopy is also used to study the physical properties of many other types of celestial objects such as planets, nebulae, galaxies, and active galactic nuclei. Background Astronomical spectroscopy is used to measure three major bands of radiation in the electromagnetic spectrum: visible light, radio waves, and X-rays. While all spectroscopy looks at specific bands of the spectrum, different methods are required to acquire the signal depending on the frequency. ...

James Webb Space Telescope
The James Webb Space Telescope (JWST) is a space telescope which conducts infrared astronomy. As the largest optical telescope in space, its high resolution and sensitivity allow it to view objects too old, distant, or faint for the Hubble Space Telescope. This will enable investigations across many fields of astronomy and cosmology, such as observation of the first stars, the formation of the first galaxies, and detailed atmospheric characterization of potentially habitable exoplanets. The U.S. National Aeronautics and Space Administration (NASA) led JWST's design and development and partnered with two main agencies: the European Space Agency (ESA) and the Canadian Space Agency (CSA). The NASA Goddard Space Flight Center (GSFC) in Maryland managed telescope development, the Space Telescope Science Institute in Baltimore on the Homewood Campus of Johns Hopkins University operates JWST, and the prime contractor was Northrop Grumman. The telescope is named after James E. Webb, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Silmarils
The Silmarils (Quenya in-universe ''pl''. ''Silmarilli'', ''radiance of pure light''Tolkien, J. R. R., "Addenda and Corrigenda to the Etymologies — Part Two" (edited by Carl F. Hostetter and Patrick H. Wynne), in ''Vinyar Tengwar'', 46, July 2004, p. 11) are three fictional brilliant jewels in J. R. R. Tolkien's legendarium. They were made by the elf Fëanor, capturing the unmarred light of the Two Trees of Valinor. The Silmarils play a central role in Tolkien's book ''The Silmarillion'', which tells of the creation of Eä (the universe) and the beginning of Elves, Dwarves and Men. Tolkien, a philologist, derived the idea of Silmarils, jewels that actually contained light, from the Old English word ''Siġelwara''; he concluded that ''Siġel'' meant both ''sun'' and ''jewel''. Scholars have described the Silmarils as embodying elvish pride in their own creation, or a Biblical desire for knowledge of good and evil as in the Genesis story of Garden of Eden.

The Silmarillion
''The Silmarillion'' () is a collection of myths and stories in varying styles by the English writer J. R. R. Tolkien. It was edited and published posthumously by his son Christopher Tolkien in 1977, assisted by the fantasy author Guy Gavriel Kay. It tells of Eä, a fictional universe that includes the Blessed Realm of Valinor, the once-great region of Beleriand, the sunken island of Númenor, and the continent of Middle-earth, where Tolkien's most popular works—''The Hobbit'' and ''The Lord of the Rings''—are set. After the success of ''The Hobbit'', Tolkien's publisher Stanley Unwin requested a sequel, and Tolkien offered a draft of the writings that would later become ''The Silmarillion''. Unwin rejected this proposal, calling the draft obscure and "too Celtic", so Tolkien began working on a new story that eventually became ''The Lord of the Rings''. ''The Silmarillion'' has five parts. The first, ''Ainulindalë'', tells in mythic style of the creation of Eä, the "worl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
