Carole Ann Haswell
Carole Ann Haswell is a British astrophysicist and current Professor of Astrophysics and Head of Astronomy at the Open University. She is a Fellow of the Royal Astronomical Society. She has been involved in the detection of several exoplanets, including Barnard's Star b. Early life and education Haswell was born in Saltburn-by-the-Sea, North Yorkshire, and grew up in Dormanstown. Her father worked on an ammonia recovery plant at Imperial Chemical Industries. She became interested in space as a child, when her father told her about the Apollo astronauts as they gazed at the Moon while on Redcar beach. Although she originally wanted to be an astronaut, she realised at the age of ten that this was impractical. She attended Huntcliff School where she worked towards her GCE Ordinary Levels. Whilst a student at Prior Pursglove and Stockton Sixth Form College, Haswell was interested in art, mathematics and physics, and was a fan of the television show '' Star Trek''. One of her ...

Open University
The Open University (OU) is a British public research university and the largest university in the United Kingdom by number of students. The majority of the OU's undergraduate students are based in the United Kingdom and principally study off-campus; many of its courses (both undergraduate and postgraduate) can also be studied anywhere in the world. There are also a number of full-time postgraduate research students based on the 48-hectare university campus in Milton Keynes, where they use the OU facilities for research, as well as more than 1,000 members of academic and research staff and over 2,500 administrative, operational and support staff. The OU was established in 1969 and was initially based at Alexandra Palace, north London, using the television studios and editing facilities which had been vacated by the BBC. The first students enrolled in January 1971. The university administration is now based at Walton Hall, Milton Keynes, in Buckinghamshire, but has administratio ...

Prior Pursglove And Stockton Sixth Form College
Prior Pursglove and Stockton Sixth Form College is a sixth form college with sites in Guisborough and Stockton-on-Tees. The college is a result of a merger between Prior Pursglove College and Stockton Sixth Form College in May 2016. The college is led by the Principal (Asma Shaffi) who is accountable to the board of governors. The college educates around 1,600 students on the Guisborough campus, and 700 students on the Stockton campus. History In 1561, Robert Pursglove set up a free school on the site which would later come to house Prior Pursglove College. The school existed to enable local boys to learn Latin and also served as an Almshouse for twelve local elderly residents. The school and almshouse was reformed in the 1880s to become Guisborough Grammar School, which lasted until 1971 before becoming Prior Pursglove College. Prior Pursglove merged with South Park Sixth Form College in 1997, eventually consolidating the provision of education on to the Guisborough campus. P ...

Barnard College
Barnard College of Columbia University is a private women's liberal arts college in the borough of Manhattan in New York City. It was founded in 1889 by a group of women led by young student activist Annie Nathan Meyer, who petitioned Columbia University's trustees to create an affiliated college named after Columbia's recently deceased 10th president, Frederick A.P. Barnard. Barnard College was one of more than 120 women's colleges founded in the 19th century, and one of fewer than 40 in existence today solely dedicated to the academic empowerment of women. The acceptance rate of the Class of 2025 was 11.4% and marked the most selective and diverse class in the college's 133-year history, with 66% of incoming U.S. students self-identifying as women of color. Barnard is one of Columbia University's four undergraduate colleges. Founded as a response to Columbia's refusal to admit women into their institution until 1983, Barnard is affiliated with but legally and financially sep ...

Cataclysmic Variable Star
In astronomy, cataclysmic variable stars (CVs) are stars which irregularly increase in brightness by a large factor, then drop back down to a quiescent state. They were initially called novae (), since ones with an outburst brightness visible to the naked eye and an invisible quiescent brightness appeared as new stars in the sky. Cataclysmic variable stars are binary stars that consist of two components; a white dwarf primary, and a mass transferring secondary. The stars are so close to each other that the gravity of the white dwarf distorts the secondary, and the white dwarf accretes matter from the companion. The tightest currently observed orbit in a hydrogen-rich system is 51 minutes in ZTF J1813+4251. Therefore, the secondary is often referred to as the ''donor star''. The infalling matter, which is usually rich in hydrogen, forms in most cases an accretion disk around the white dwarf. Strong UV and X-ray emission is often seen from the accretion disc, powered by the loss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
X-ray Transient
X-ray emission occurs from many celestial objects. These emissions can have a pattern, occur intermittently, or as a transient astronomical event. In X-ray astronomy many sources have been discovered by placing an X-ray detector above the Earth's atmosphere. Often, the first X-ray source discovered in many constellations is an X-ray transient. These objects show changing levels of X-ray emission. NRL astronomer Dr. Joseph Lazio stated: " ... the sky is known to be full of transient objects emitting at X- and gamma-ray wavelengths, ...". There are a growing number of recurrent X-ray transients. In the sense of traveling as a transient, the only stellar X-ray source that does not belong to a constellation is the Sun. As seen from Earth, the Sun moves from west to east along the ecliptic, passing over the course of one year through the twelve constellations of the Zodiac, and Ophiuchus. Exotic X-ray transients SCP 06F6 is (or was) an astronomical object of unknown type, discover ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Black Hole
A black hole is a region of spacetime where gravitation, gravity is so strong that nothing, including light or other Electromagnetic radiation, electromagnetic waves, has enough energy to escape it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary (topology), boundary of no escape is called the event horizon. Although it has a great effect on the fate and circumstances of an object crossing it, it has no locally detectable features according to general relativity. In many ways, a black hole acts like an ideal black body, as it reflects no light. Moreover, quantum field theory in curved spacetime predicts that event horizons emit Hawking radiation, with thermal radiation, the same spectrum as a black body of a temperature inversely proportional to its mass. This temperature is of the order of billionths of a kelvin for stellar black holes, making it essentially impossible to observe directly. Obje ...

Accretion (astrophysics)
In astrophysics, accretion is the accumulation of particles into a massive object by gravitationally attracting more matter, typically gaseous matter, in an accretion disk. Most astronomical objects, such as galaxies, stars, and planets, are formed by accretion processes. Overview The accretion model that Earth and the other terrestrial planets formed from meteoric material was proposed in 1944 by Otto Schmidt, followed by the ''protoplanet theory'' of William McCrea (1960) and finally the ''capture theory'' of Michael Woolfson. For details of Kant's position, see In 1978, Andrew Prentice resurrected the initial Laplacian ideas about planet formation and developed the ''modern Laplacian theory''. None of these models proved completely successful, and many of the proposed theories were descriptive. The 1944 accretion model by Otto Schmidt was further developed in a quantitative way in 1969 by Viktor Safronov. He calculated, in detail, the different stages of terrestrial plane ...

Hubble Space Telescope
The Hubble Space Telescope (often referred to as HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. It was not the first space telescope, but it is one of the largest and most versatile, renowned both as a vital research tool and as a public relations boon for astronomy. The Hubble telescope is named after astronomer Edwin Hubble and is one of NASA's Great Observatories. The Space Telescope Science Institute (STScI) selects Hubble's targets and processes the resulting data, while the Goddard Space Flight Center (GSFC) controls the spacecraft. Hubble features a mirror, and its five main instruments observe in the ultraviolet, visible, and near-infrared regions of the electromagnetic spectrum. Hubble's orbit outside the distortion of Earth's atmosphere allows it to capture extremely high-resolution images with substantially lower background light than ground-based telescopes. It has recorded some of the most detaile ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Binary Black Hole
A binary black hole (BBH) is a system consisting of two black holes in close orbit around each other. Like black holes themselves, binary black holes are often divided into stellar binary black holes, formed either as remnants of high-mass binary star systems or by dynamic processes and mutual capture; and binary supermassive black holes, believed to be a result of galactic mergers. For many years, proving the existence of binary black holes was made difficult because of the nature of black holes themselves and the limited means of detection available. However, in the event that a pair of black holes were to merge, an immense amount of energy should be given off as gravitational waves, with distinctive waveforms that can be calculated using general relativity. Therefore, during the late 20th and early 21st century, binary black holes became of great interest scientifically as a potential source of such waves and a means by which gravitational waves could be proven to exist. Binar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Summer Eights
Eights Week, also known as Summer Eights, is a four-day regatta of bumps races which constitutes the University of Oxford's main intercollegiate rowing event of the year. The regatta takes place in May of each year, from the Wednesday to the Saturday of the fifth week of Trinity Term. Men's and women's coxed eights compete in separate divisions for their colleges. Overview The racing takes place on the Isis, a length of the River Thames, which is generally too narrow for side by side racing. For each division, thirteen boats line up at the downstream end of the stretch, each cox holding onto a rope attached to the bank, leaving around 1.5 boat lengths between each boat. The start of racing is signalled by the firing of a cannon, each crew attempting to progress up their division by bumping the boat in front, while avoiding being bumped by the boat behind. Once a bump has taken place, both of the crews involved stop racing and move to the side to allow the rest of the d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University College, Oxford
University College (in full The College of the Great Hall of the University of Oxford, colloquially referred to as "Univ") is a constituent college of the University of Oxford in England. It has a claim to being the oldest college of the university, having been founded in 1249 by William of Durham. As of 2018, the college had an estimated financial endowment of £132.7m. The college is associated with a number of influential people, including Clement Attlee, Harold Wilson, Bill Clinton, Neil Gorsuch, Stephen Hawking, C. S. Lewis, V. S. Naipaul, Robert Reich, William Beveridge, Bob Hawke, Robert Cecil, and Percy Bysshe Shelley. History A legend arose in the 14th century that the college was founded by King Alfred in 872. This explains why the college arms are those attributed to King Alfred, why the Visitor is always the reigning monarch, and why the college celebrated its millennium in 1872. Most agree that in reality the college was founded in 1249 by William of Durham ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
