What type of galaxy is the Milky Way? + rb + Elliptical; Spiral Barred; Spiral; Irregular + 3
Describe the appearance of the Milky Way from Earth. + rb + A fuzzy streak of gas; A straight white line; A fuzzy spiral of gas; A thick bar of grey gas + 1
Where is our Solar System located in the Milky Way? + rb + At the centre; In the central bar; In the left outer lobe; In one of the spiral arms; Outside the galaxy + 4
Explain how the rotation period of the galaxy was determined. + cb + Tracer stars were used in globular clusters; Tracer stars were used at the centre of the galaxy; Radio waves were used; Visible light was used + 1;3
The Galactic Centre of the Milky Way is in which constellation? + rb + Aquarius; Sagittarius; Libra; Pisces + 2
The centre of the galaxy is a large bulge. What do astronomers believe there is there? + rb + An ancient civilisation; Another smaller galaxy; A super-massive star; A super-massive Black Hole + 4
Globular clusters are found around the Milky Way in a... + ww + halo
What is the name of this diagram? + img +galaxies-diagram.png+ rb + Hubble's Tuning Fork Diagram; Hubble's River Diagram; Kepler's Tree Diagram; Kepler's River Diagram + 1
What is the following statement describing? "Galaxies that emit large quantities of radiation such as radio-waves and x-rays". + rb + Radio Galaxies; Loud Galaxies; Active Galaxies; Seyfert Galaxies + 3
Active Galactic Nuclei are found in galaxies at the... + ww + centre
Why do Active Galactic Nuclei emit electromagnetic waves? + rb + They are dense with stars, emitting lots of light; An accreting disc of matter surrounds a supermassive black hole. As the matter falls in, radiaton is released; Two super-massive white stars orbit each other at the centre. As gas is transferred between them, radiation is released; The swirling cloud of gas at the centre is very hot and so releases radiation + 2
What's the difference between a Quasar and a Blazar? + rb + Blazars radiate gamma rays; Blazars are a tenth of the size as Quasars; Quasars emit ultra-low frequency radio waves; There is no difference + 1
What is the following statement describing? "Elliptical galaxies that emit over 1 million times more radiation than normal galaxies from a symmetrical pair of lobes".+ rb + Radio Galaxies; Fire Galaxies; Seyfert Galaxies; Quasars + 1
What is the following statement describing? "Spiral galaxies with very compact nuclei. Emit strong IR and x-rays".+ rb + Radio Galaxies; Fire Galaxies; Seyfert Galaxies; Quasars + 3
What is the following statement describing? "Highly compact galaxies that look like stars and radiate huge amounts of energy".+ rb + Radio Galaxies; Fire Galaxies; Seyfert Galaxies; Quasars + 4
How big is the Local Group to the nearest Mpc? + wn + 3
The Local Group contains roughly 50 galaxies. Tick all of the galaxies this includes. + cb + The Milky Way; The Triangulum Galaxy; The Lupus Galaxy; The Lobed Galaxy; The Nubus Galaxy + 1;2
What is the correct order of classifaction from smallest to largest? + rb + Solar System -> Galaxy -> Local Group -> Local Cluster -> Super Cluster; Solar System -> Galaxy -> Local Cluster -> Super Cluster -> Local Group; Local Group -> Solar System -> Galaxy -> Local Cluster -> Super Cluster + 1
How do stars in Globular Clusters differ from stars in the Milky Way? Tick all that apply. + cb + They are younger; They are older; They are redder; They are bluer; They are hotter; They are colder + 2;3;6
