Galaxies are collections of gas, dust, and stars held together by gravity. There are over 125 billion galaxies in the universe. The Milky Way galaxy contains our solar system and approximately 100 billion other stars. Galaxies come in three main shapes - spiral, elliptical, and irregular. Spiral galaxies have arms spiraling out from a central bulge, while elliptical galaxies are spherical or elliptical in shape.

The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

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

3. What is a Galaxy?
• From the Greek word for milk: galaktos
• A galaxy is a collection of gas, dust and stars held together by
gravity
• Astronomers estimate there are over 125 billion galaxies in the
universe
4. The Milky Way
• Our solar system is contained in the Milky Way galaxy
• Our sun is one of approximately 100 billion stars in this galaxy
5. Galaxies
• Edwin Hubble in 1925 identified the first galaxy outside of our
own. Our nearest neighbouring galaxy Andromeda
• Hubble initially thought he was observing a nebula
• Nebula: Cloud of gas and dust often where stars are formed
6. Galaxy Shapes
• Galaxies are classified as one of three basic shapes:
• Spiral, Elliptical or Irregular
7. Spiral Galaxy
• When viewed from above looks like a pinwheel
• Many long arms spiraling out from a central core
• Central bulge is made of stars formed long ago
• Outer arms are made of dust and newly formed stars
• Glowing halo of stars surrounds the entire galaxy
• Milky Way and Andromeda are both examples of spiral
galaxies
8. Elliptical Galaxy
• Spherical to stretched out ellipse shape
• Contain some of the oldest stars in the universe
• Some of the largest galaxies in the universe are elliptical
• More than half of all galaxies are elliptical
9. Irregular Galaxy
• Does not have any regular shape to categorize it as elliptical or
spiral
• Contains a mixture of old and new stars
11. Features of Galaxies
• Composition: Amount and type of stars, gas and dust
• Size: Dwarf to Supergiants
• Spin: Faster spin leads to flatter galaxies
• Star Formation: Star clusters are distinct groups of stars
• Globular Cluster
• Open Cluster
