Comets are chunks of ice and dust that have long, elliptical orbits around the sun. They originate from two areas in the solar system - the Kuiper Belt just outside Neptune's orbit, and the distant Oort Cloud beyond Pluto. Comets are made up of three main parts: the icy nucleus, the coma of gas and dust surrounding the nucleus, and the tail which always points away from the sun. Asteroids are smaller rocky objects that reside mainly in the asteroid belt between Mars and Jupiter. Meteors are streaks of light seen when meteoroid rocks from space burn up in Earth's atmosphere, and meteorites are meteoroids that survive entry and impact the surface.
This is all about comets. Their parts, their origin, and this also have The Top 10 Famous Comets. This also have the definition of the Kuiper Belt and the Oort Cloud. Have a Blast!!!
A comet is an icy small Solar System body (SSSB) that, when close enough to the Sun, displays a visible coma (a thin, fuzzy, temporary atmosphere) and sometimes also a tail. These phenomena are both due to the effects of solar radiation and the solar wind upon the nucleus of the comet. Comet nuclei range from a few hundred meters to tens of kilometers across and are composed of loose collections of ice, dust and small rocky particles. Comets have been observed since ancient times.
Comets have a wide range of orbital periods, ranging from a few years to hundreds of thousands of years. Short-period comets originate in the Kuiper belt, or its associated scattered disc,[1] which lie beyond the orbit of Neptune. Longer-period comets are thought to originate in the Oort cloud, a hypothesized spherical cloud of icy bodies in the outer Solar System. Long-period comets plunge towards the Sun from the Oort cloud because of gravitational perturbations caused by either the massive outer planets of the Solar System (Jupiter, Saturn, Uranus, and Neptune), or passing stars. Rare hyperbolic comets pass once through the inner Solar System before being thrown out into interstellar space along hyperbolic trajectories. Exocomets, comets beyond our solar system, have also been detected and may be common in the Milky Way Galaxy.[2]
Comets are distinguished from asteroids by the presence of a coma or a tail. However, extinct comets that have passed close to the Sun many times have lost nearly all of their volatile ices and dust and may come to resemble small asteroids.[3] Asteroids are thought to have a different origin from comets, having formed inside the orbit of Jupiter rather than in the outer Solar System.[4][5] The discovery of main-belt comets and active centaurs has blurred the distinction between asteroids and comets (see asteroid terminology).
As of January 2011 there are a reported 4,185 known comets[6] of which about 1,500 are Kreutz Sungrazers and about 484 are short-period.[7] This number is steadily increasing. However, this represents only a tiny fraction of the total potential comet population: the reservoir of comet-like bodies in the outer Solar System may number one trillion.[8] The number visible to the naked eye averages roughly one per year, though many of these are faint and unspectacular.[9] Particularly bright or notable examples are called "Great Comets".

b) Explain how the three debris fields (i.e., Main Asteroid Belt, Kuiper Belt, and Oort Cloud) formed in the Solar System. c) Explain the planetary accretion process whereby the planets in the Solar System formed.
Solution
Solution B)
Asteroid Belt : The Asteroid Belt consists of hundreds of thousands of rocks, with all kinds of different shapes, ranging in size from the Dwarf Planet Ceres at 950 Km in Diameter, down to small bits the size of dust particles. It lies between Mars and Jupiter.
Formation - when our solar system was being formed, a tenth planet tried to form between Mars and Jupiter. However, Jupiter s gravitational forces were too strong, so the material was unable to form a planet. Even if a planet had formed it wouldnt have been anything write about . It is estimated that if you put all the asteroid into the solar system into one body thwy would form an object less than half the size of moon.
Kuiper Belt : The Kuiper Belt (pronounced Kai-per) consists of Icy rocks, and it a major source of short-period Comets in the Solar system. Extending beyond the planet Neptune, Pluto was discovered to be one of the largest objects in the belt.
Formation - When the solar system formed, much of the gas, dust and rocks pulled together to form the sun and planets. The planets then swept most of the remaining debris into the sun or out of the solar system
Oort Cloud : Oort cloud is a collection of Comets, thought to extend far beyond the planets of the Solar System. the Oort comets are distributed spherically about the Sun, possibly extending as far as half way to the next star. The Oort orbits are not regular or planar like the Asteroid and Kuiper belts, and are often perturbed through gravitational interactions during their long journeys on highly eccentric orbits.
Formation : The Oort Cloud is roughly spherical, and is thought to be the origin of most of the long-period comets that have been observed. This cloud of particles is theorized to be the remains of the disc of material that formed the Sun and planets.

June 3, 2024 Anti-Semitism Letter Sent to MIT President Kornbluth and MIT Cor...Levi Shapiro
Letter from the Congress of the United States regarding Anti-Semitism sent June 3rd to MIT President Sally Kornbluth, MIT Corp Chair, Mark Gorenberg
Dear Dr. Kornbluth and Mr. Gorenberg,
The US House of Representatives is deeply concerned by ongoing and pervasive acts of antisemitic
harassment and intimidation at the Massachusetts Institute of Technology (MIT). Failing to act decisively to ensure a safe learning environment for all students would be a grave dereliction of your responsibilities as President of MIT and Chair of the MIT Corporation.
This Congress will not stand idly by and allow an environment hostile to Jewish students to persist. The House believes that your institution is in violation of Title VI of the Civil Rights Act, and the inability or
unwillingness to rectify this violation through action requires accountability.
Postsecondary education is a unique opportunity for students to learn and have their ideas and beliefs challenged. However, universities receiving hundreds of millions of federal funds annually have denied
students that opportunity and have been hijacked to become venues for the promotion of terrorism, antisemitic harassment and intimidation, unlawful encampments, and in some cases, assaults and riots.
The House of Representatives will not countenance the use of federal funds to indoctrinate students into hateful, antisemitic, anti-American supporters of terrorism. Investigations into campus antisemitism by the Committee on Education and the Workforce and the Committee on Ways and Means have been expanded into a Congress-wide probe across all relevant jurisdictions to address this national crisis. The undersigned Committees will conduct oversight into the use of federal funds at MIT and its learning environment under authorities granted to each Committee.
• The Committee on Education and the Workforce has been investigating your institution since December 7, 2023. The Committee has broad jurisdiction over postsecondary education, including its compliance with Title VI of the Civil Rights Act, campus safety concerns over disruptions to the learning environment, and the awarding of federal student aid under the Higher Education Act.
• The Committee on Oversight and Accountability is investigating the sources of funding and other support flowing to groups espousing pro-Hamas propaganda and engaged in antisemitic harassment and intimidation of students. The Committee on Oversight and Accountability is the principal oversight committee of the US House of Representatives and has broad authority to investigate “any matter” at “any time” under House Rule X.
• The Committee on Ways and Means has been investigating several universities since November 15, 2023, when the Committee held a hearing entitled From Ivory Towers to Dark Corners: Investigating the Nexus Between Antisemitism, Tax-Exempt Universities, and Terror Financing. The Committee followed the hearing with letters to those institutions on January 10, 202

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

Acetabularia Information For Class 9 .docxvaibhavrinwa19
Acetabularia acetabulum is a single-celled green alga that in its vegetative state is morphologically differentiated into a basal rhizoid and an axially elongated stalk, which bears whorls of branching hairs. The single diploid nucleus resides in the rhizoid.
3. Comets probably come from two areas of the Solar System: 1. The Kuiper belt – found just outside the orbit of Neptune. (home of short period comets ) like Halley’s Comet.
