What type of telescope is the Spitzer telescope?

infrared space telescope At its launch in 2003, NASA's Spitzer Space Telescope was the most sensitive infrared space telescope in history. Its 16-year lifetime revolutionized our view of the cosmos. Spitzer made discoveries from inside our solar system to nearly the edge of the Universe.

How do the Type II and Type Ia supernovae differ quizlet?

The smaller planets are Mercury, Venus, Earth, and Mars. The inner planets are rocky and have small diameters. The outer planets include Jupiter. Gas giants are planets with a diameter greater than 48,000 kilometers.

Is the Chandra telescope still working?

Chandra is an Earth satellite in a 64-hour orbit, and its mission is ongoing as of 2021. Chandra is one of the Great Observatories, along with the Hubble Space Telescope, Compton Gamma Ray Observatory (1991?2000), and the Spitzer Space Telescope (2003?2020). Thereof, how does positive and negative electricity work? Electric charge can be positive or negative (commonly carried by protons and electrons respectively). If there are more electrons than protons in a piece of matter, it will have a negative charge, if there are fewer it will have a positive charge, and if there are equal numbers it will be neutral.

What happens when a positive and a positive meet?

In contrast to the attractive force between two objects with opposite charges, two objects that are of like charge will repel each other. That is, a positively charged object will exert a repulsive force upon a second positively charged object. This repulsive force will push the two objects apart. Then, what does negatively charged mean? electrons A negative charge is an electrical property of a particle at the subatomic scale. An object is negatively charged if it has an excess of electrons, and is uncharged or positively charged otherwise.


What is the primary difference between a Type I and Type II supernova?

There are eight planets in the solar system. They are all very similar. There are different features such as size, amount of moons, and rings. They are the same because they all have a core, are round, and have gravity.

Why are electrons negatively charged?

Electrons are called negative because of the way they behave in an electric field. In an electric field, an electron will move from the negative pole to the positive, by convention that makes it a negative charge. Who has a negative charge? Electrons Electrons have a negative charge. The charge on the proton and electron are exactly the same size but opposite. Neutrons have no charge. Since opposite charges attract, protons and electrons attract each other.
