Stars, Galaxies and Nebulae

Another state of Matter Solids, Liquids and Gasses Plasma—like a gas, except can be charged electrically In this plasma lamp, electricity and magnet form structures

Some common Plasmas Fire Lightning The Sun and other stars

What is a star? A Luminous Ball of Plasma held together by gravity Fueled by Nuclear Fusion Hydrogen Helium And this electron escapes

A star begins With a collapsing cloud of material Mostly made of Hydrogen, the lightest, simplest element a photograph of the center of the Swan Nebula, or M17, a hotbed of newly born stars wrapped in colorful blankets of glowing gas and cradled in an enormous cold, dark hydrogen cloud.

One Nebula, two Nebulae Clouds of dust and gas (especially hydrogen) where stars form The Horsehead Nebula

A Gallery of Nebulae The Bubble Nebula

The Eagle Nebula

HH-666 Also known as “the axis of evil in the Carina Nebula”

Rossette Nebula

Part of the Eagle Nebula

Triangulum Emission Garren Nebula

Cat’s Eye Nebula

Red rectangle nebula

How do they take these pictures? The Hubble Telescope Launched in 1990 Will stop working this year

Webb telescope Will be launched in 2013 Will be beyond the moon

Galaxies Huge groups of stars, Star clusters Interstellar clouds

Types of Galaxies

Elliptical

Spiral

A Barred Spiral Galaxy

Milky Way Our Home Galaxy! A Barred Spiral Galaxy

Ring Galaxy

Starburst Galaxies Stars form at a fast rate

How many galaxies? More than 170 billion 170,000,000,000 More being discovered all the time!

How many Stars in a Galaxy? As few as 10 million (10,000,000) As many as 1 trillion (1,000,000,000,000)

Our Galactic Cluster is called The Local Group – it has about 30 galaxies ters/localg.html

Our Galactic Address! Name - Street, City, Postal Code - Continent - Planet – Earth Star – the Sun Galaxy – Milky Way Galaxy Cluster – The Local Group

Dark Matter We can’t see it But it has gravity– a lot! Makes up 90% of galaxies Something scientists are trying to find out about right now ?

Black Holes A place from which nothing can escape Not even light! Very compact mass in a deformation of spacetime

Supermassive Black Hole What it sounds like At the center of most, if not all, galaxies Here, an artist has imagined a supermassive black hole tearing a star apart

Supernova A star explosion Burns all its material in a few weeks or months

Red Giants Towards the end of a star’s life Expands to 9 times it size Starts to fuse carbon, neon, silicon and oxygen This star is Betelgeuse

Collapse Will eventually collapse into a “planetary nebula” Remnants may be recycled into new stars

Quiz-time! What element is being fused in the sun and other stars to make energy and helium? Hydrogen

What do we call gas that can be electrically charged? Plasma Some examples? Fire, lightning, stars

What do we call a region of clouds of gas where stars form? a Nebula The plural? Nebulae

What is the name of this nebula? The Horsehead Nebula

What will not let anything escape, not even light? A Black Hole

What is a star explosion called? A Supernova

To Know for Midterm Astronomical Unit – distance between planets Light Years – distance between stars and galaxies Star Nebula Galaxy
