A place to unpuzzle your mind on those tricky definitions or acronyms
A great page to visit is this one put out by NASA.There is a ton of info on any possible astronomical topic you can think of!!!
galaxy M81 found in Ursa Major
Image of a pulsar with
magnetic field lines around the star, forcing matter to come in or leave
the star through either the north or the south pole. The red line
symbolizes the axis, and the blue arrows show the direction that the
star rotates. In this drawing, the pulsar rotates counter clockwise.
Image of a quasar at the center of
a galaxy
Artists conception of a normal star (HDE 226868) and a black hole taking matter from the normal star. The matter swirls around the black hole. When the matter (gas or dust) passes the point of no return, it sends off X-rays into space (the ziggly red lines).
Image of a black hole (right) and a neutron star (left). The matter is circling around the black hole before it is pulled into infinite density. The center of that picture is black because black holes are invisible. The neurton star absorbs the matter that is circling around it, however it is not black in the middle, a star can be seen.
white dwarf Sirius B
Cassiopeia A supernova
remnant
Image of the Trifid nebula
Image of a CV star system. One
normal star and a white dwarf. The white dwarf star is taking the matter
from the normal star. The matter is circling the white dwarf star because
it cannot hold all that material at one time. The accretion disk is where
X-rays are formed
