Stars are born in vast nebulae clouds of dust and gas scattered throughout space. Gravity gathers hydrogen in these clouds, causing them to grow denser and hotter over time. Eventually, the hydrogen heats up to 18 million degrees Fahrenheit, igniting nuclear fusion reactions that turn the hydrogen into helium - this is the moment a star is born. The color of stars depends on their temperature, ranging from hot blue-white to cooler and dimmer red. The largest known star is VY Canis Majoris, which could fit the sun inside it over 2,000 times.

If someone says to you, I believe there might be planets around K-.pdfartcraft14
If someone says to you, \"I believe there might be planets around K-type stars\", how would you
respond? Defend your answer with the formation of the solar system.
Solution
A K-type star is the main sequence star on an HR-digram because the they are hydrogen-burning
stars. K-type stars usually weigh around 0.45 to 0.8 solar masses, and they have a surface
temperature of 3,900 and 5,200 K, they live on the main sequence for a very long time
approximately 15 to 30 billion years. Researchers believe that the solar system was formed from
a cloud of gas and dust in space was perturbed, maybe by the explosion of a nearby star. This
explosion made waves in space which compressed the cloud of gas and dust. Compressing made
the cloud start to collapse under its on gravity, a, forming a solar nebula. Just like an Ice-skater
that spins faster as she pulls in her arms, the cloud begins to spin as it collapses. Eventually, the
cloud grows hotter and denser in the center, with a disk of gas and dust surrounding it that was
hot in the middle but cool at the edges. As the disk got thinner and thinner, particles began to pile
together and form clumps. Some clumps got bigger, as particles and small clumps stuck to them,
eventually forming planets or moons. Near the center of the cloud, where planets likeEarth
formed, the only rocky material could stand the great heat. Icy matter settled in the outer regions
of the disk along with rocky material, where the giant planets likeJupiter formed. As the cloud
continued to fall in, the center eventually got so hot that it became a star, the Sun, and blew most
of the gas and dust of the new solar system with a strong stellar wind. By studying meteorites,
which are thought to be left over from this early phase of the solar system, scientists have found
that the solar system is about 4600 million years old. A K-type star will need similar conditions
to form it self and the debris form the star formation can lead to the formation of planets..

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.

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.

2. What is a star?
A star is a giant
luminous ball of super
heated gas. Just like
our star, The Sun.
They are scattered
throughout the space
so far away, that we
would need one
hundred thousand
years to reach them.
3. How are stars born?
They begin in clouds of
dust and gas very far
away.
Gravity gathers
hydrogen gas and
particles of dust and the
clouds grow more dense.
As it squeezes itself
tighter, the hydrogen
heats up to a fantastic 18
million ºF (10 million
ºC). Nuclear fusion turns
hydrogen into helium
and the fire ignites.
4. Where are stars born?
Stars are born in vast clouds
in the space called nebulae.
A nebulae is an interstellar
cloud of dust, hydrogen,
helium and other ionized
gases.
These clouds are also called
molecular clouds. Here,
temperatures can drop
down until -441 ºF (-263 ºC).
5. What color are stars?
The color of stars depend on
how hot they are. The
temperature varies along a
band on a graph called the
Main Sequence.
The colors go from hot and
bright blue-white to cool
and dim red.
6. What is the biggest star?
The biggest stars are
the supergiants.
Antares is 700 times as
big as the Sun. The
largest star we know
of, is called VY Canis
Majoris.
We could probably fit
the Sun inside VY
Canis Majoris 2100
times.
7. How many stars are
there?
What makes stars twinkle?
Stars twinkle because the Earth’s
atmosphere is never still. Starlight
twinkles as the air wavers.
It is hard to know how many stars
there are in the universe. But
astronomers guess there are about
200 billion billion.
What makes stars glow?
They glow because the enormous pressure
deep inside generates nuclear fusion
reactions.
