Magnetic field of Sun´s Atmosphere
observation from
Coronal Multi-channel Polarimeter (CoMP)
Instrument
provide measurement
infrared radiation
coming from
Sun´s atmosphere
Sun is a magnetized star
Technique
called Magnetoseismology
measure magnetic field of corona
use of magnetic waves
known as Alfven waves
corona hotter than sun´s surface
Magnetic reconnection
Process
where oppositely
polarity magnetic
field lines connect
some of magnetic energy
converted to heat energy
also kinetic energy
leads to generation of heating,
solar flares, solar jets, etc
Mechanisms
eruptions of sun
such as
solar flares and coronal mass ejections
driven by
magnetic reconnections
Perseids Meteor Shower
every year in mid-Aug
comets
Every time comets come close to sun
leave behind dust
essentially the debris trail
earth passes through every year
Meteors
Space rocks extremely hot
behind streaks of glowing gas
Perseids occurs
Earth runs into Pieces of cosmic
debris left behind by
comet Swift-Tuttle
SPT0418-47
galaxy away resembling our Milky way
Alma radio telescope in Chile
using a technique called
gravitational lensing
distribution of matter
btw a distant light source and observer
capable of bending the light
from the source
as the light travels
towards the observer
Omega Centauri
