COMETS, TELESCOPES, SUN

COMETS

• Each comet has a tiny frozen part in the middle called the nucleus.
• Comets are made of ice, gases, and rock.
• A comet warms up nears the sun and forms a coma or atomshpere.
• When it nears the sun the gases melt and the coma gets bigger.
• A comet has 2 tails a dust one and a plasma.

COMETS

• Comets travel on a long oval path called ellipses.
• There are 6 main groups of comets:
• Short period,long period, single apparition,periodic ,non periodic and main belt comets
• Comets are left overs from the dawn of the solar system 4.6 billion years ago

LIGHT YEARS

• It is not what it sounds like.
• It's is a measurement.
• The formula is 9.4605384 x 10 to the 15 power.

TELESCOPES/SPECTROSCOPE

• The telescope lets you see farther in space
• The spectroscope has two things
• - spectrometer is to pick the color you wanna view the space with
• - photometer is to measure intensity in light
• The telescope has one eyepiece and a focusing knob and one huge magnify glass

TELESCOPES/SPECTROSCOPES

• In the beginning Galileo was the astronomer who invented the telescope
• Then we came and progressed from that knowledge and made more advanced telescopes
• How to use telescops: point and angle the telescope with the axis
• Telescopes are used to look in the sky and spectroscopes are to collect chemical components in celestial objects
• With this technology we are able to photograph objects in space

SUN/SOLAR ACTIVITIES

• Sunspots are relatively cool dark features on the sun.
• They emerge where bundles of magnetic field lines from sun breaks through the surface.
• The sun has three regions : the photosphere, the chromosphere,and the corona.
• Solar flares are solar activities that are mini explosions on the sun.
