A brief description of why the Webb Telescope is optimized to observe infrared light. Hint: it has to do with the four main science areas that it will be studying: “Other Worlds,” “Star Lifecycle,” “Galaxies Over Time,” and “Early Universe.”
A brief description of the four main science goals of the James Webb Space Telescope - “Other Worlds,” “Star Lifecycle,” “Galaxies Over Time,” and “Early Universe.”
A brief description of the James Webb Space Telescope and how it's different than the Hubble Space Telescope.
A brief description of the Hubble Space Telescope and its scientific capabilities.
A brief description of the two primary reasons why we send telescopes into space to observe and study celestial objects.
A brief historical summary of what we mean when we refer to "Spiral Nebulae."
A brief description of what will happen if the universe stops expanding and collapses back on itself - this is known as the Big Crunch.
A brief description of the basic properties of astronomical objects such as mass, radius, distance, luminosity, and temperature.
A brief description of the Local Group of galaxies which contains the Milky Way, the Andromeda galaxy, and dozens of dwarf galaxies all gravitationally bound to each other.
A brief description of what scientists mean when they say we "know" something.
A brief description of the structure of atoms - how they are mostly empty space - and why the everyday objects you use don't collapse and fall in on themselves.
A brief description of what we mean when we talk about interacting galaxies.
A brief description of nuclear fusion, which is the process by which stars produce light so that they can shine.
A brief description of giant molecular clouds and why they are important for stars.
A brief description of the observational evidence we have supporting our assertion that the Milky Way galaxy is spiral in shape.
A brief description of the 21 centimeter radiation (light) that the Hydrogen atom emits and the mechanism behind this emission.
A brief description of what astronomers mean when they say that "all pulsars are neutron stars but not all neutron stars are pulsars."
A brief description of neutron stars, which are essentially the end state of massive stars some of which become pulsars.
A brief description of a white dwarf star, which is the end-state of a star that is less than 8 times the mass of Sun.
A brief description of how we use the HR Diagram and the main sequence to measure the ages of stars in groups and clusters.
A brief description of seeing and the resolving power of a telescope.
A brief description of the true nature of black holes as highly localized sources of gravity and not cosmic vacuum cleaners.
A brief description of what we think was here before the Big Bang. Short answer is that we don't know since "Science" is not equipped to answer questions where no data or information is available.
A brief description of my personal point of view regarding the possibility that UFOs harbor extraterrestrial beings visiting Earth.
