What does Doctor P mean?
Origin of name In an interview, Doctor P stated that the “P” in his name stands for Picto, which was a nickname of his. It came from a predictive text suggestion that popped up when his name was typed (furthermore, one of his friends, following that, called him “Doctor Picto”).
Why do we study galaxies?
Why Is It Important to Understand Galaxies? Galaxies show us how the matter in the universe is organized on large scales. In order to understand the nature and history of the universe, scientists study how the matter is currently organized and how that organization has changed through out cosmic time.
Why do galaxies form disks?
So galaxies form disc shapes because the gas that makes stars falls into a disc shape. However, not all galaxies are discs. When disc-shaped galaxies collide, this can disturb the orbits of the stars, and you get a galaxy which is “blob” shaped, these are called elliptical galaxies, and are very common.
Why are older stars in the center of a spiral galaxy?
Around two-thirds of spiral galaxies also contain a bar structure through their center, the same as our Milky Way. The disk of stars orbiting the bulge tends to separate into arms that circle the galaxy. These spiral arms contain a wealth of gas and dust, thus many young stars are birthed in these regions.
Which types of galaxies have evolved most?
Elliptical galaxies are more likely found in crowded regions of the universe (such as galaxy clusters). Astronomers now see elliptical galaxies as some of the most evolved systems in the universe. It is widely accepted that the main driving force for the evolution of elliptical galaxies is mergers of smaller galaxies.
What type of stellar motion is best seen in the Galactic disk?
The stars in the Galaxy define various components, that do not only differ in their spatial distribution but also in their kinematics. The dominant motion of stars (and gas) in the Galactic disk is rotation (around the centre of the Galaxy), and these motions occur on nearly circular orbits.
What is the motion of a galaxy?
Under the force of gravity galaxies are expected to revolve around each other and perform a dance on galactic scales. Such revolutions take billions of years and appear as ultra-slow motion on the sky due the enormous distances in the universe.

What is below a doctor?
A physician assistant (PA) is a medical professional who is licensed to diagnose patients and provide treatments under the supervision of a physician. They have a vast knowledge of different medical fields to provide well-rounded care to patients. In most states, a PA can also prescribe medications.
What does PA mean after a doctors name?
physician assistant
If you see a physician assistant (PA) rather than a medical doctor (MD) when you visit the Emergency Department of Western Maryland Health Systems (WMHS), you may feel concerned about the PA’s qualifications to treat you.
Who created galaxies?
Galaxies are thought to begin as small clouds of stars and dust swirling through space. As other clouds get close, gravity sends these objects careening into one another and knits them into larger spinning packs.
What are the three types of galaxies?
Types of Galaxies Astronomers classify galaxies into three major categories: elliptical, spiral and irregular.
What are stars and galaxies?
Stars and Galaxies 28 Sta rDat e/Univer SoteacherGU i D e StudentPage A galaxy is a gravitationally bound system of stars, gas, and dust. Gal- axies range in diameter from a few thousand to a few hundred thou- sand light-years. Each galaxy contains billions (109) or trillions (1012) of stars.
What are the characteristics of a galaxy?
A galaxy is a gravitationally bound system of stars, gas, and dust. Gal- axies range in diameter from a few thousand to a few hundred thou- sand light-years. Each galaxy contains billions (109) or trillions (1012) of stars.
What is a galaxy Axie?
A galaxy is a gravitationally bound system of stars, gas, and dust. Gal- axies range in diameter from a few thousand to a few hundred thou- sand light-years.
How many galaxies can you see beyond the Milky Way?
There are three galaxies beyond the Milky Way that you can see without optical aid: the Andromeda galaxy, the Small Magellanic Cloud, and the Large Magellanic Cloud. Figure the scaled distance to these galaxies (how many times you could fit the galaxy between itself and the Milky Way).
