lack holes in space are hard to see. But
some black holes, especially super big
ones, stand out. They gather bright rings of
gas and other material.
This year, a world-spanning network of
observatories, called the Event Horizon
Telescope (EHT), zoomed in on a huge
galaxy called M87 to create the first-ever
photograph of a black hole.

This super huge black hole is ab
about
55 million light-years away in a
galaxy called M87.
While the existence of black holes
was first discussed by Albert Einstein
and other scientists a little more than
100 years ago, it wasn’t until this April
that a photograph of one was taken.
Black Holes and Time
Replace the missing words.
If an ___________ was able to get close
to a black hole ___________ and spend a
few _________ there, a strange thing
would happen when he or she returned to
their __________. Many years might have
_______ in Earth time while the astronaut
was ______ the black hole!
What is a black hole?
When a star implodes, it collapses
in on itself. The tremendous gravity
of this can create a black hole.
A whirlpool in water is similar in
some ways to a black hole. Both
have a core that sucks in whatever
is close by, which in a black hole
includes light.
Use the Decoder Ring to
discover the name of this fun
book by Jane Yolen, which is
available at the library.
To fill in the blanks, find the
letter on the outer ring, then
replace it with the letter below
it on the inner ring.
Don’t Let the Name
Black Hole Fool You!
A black hole is not empty. Rather, it is
a great amount of matter packed into a
very small area
— think of a
star ten times
more massive
than the sun
squeezed into
a sphere
approximately
the diameter of
New York City.
Packing all
that matter into
one little space
causes a huge
gravitational
field so strong
that nothing,
not even light,
can escape.
It would be
like squashing
all the bricks, concrete, steel, wood and
glass of a large building into a tiny ball
smaller than the size of a pea.
Commander Toad and his crew
on the spaceship Star Warts
come across a black hole while
leapfrogging across the galaxy.
Something long, pink, and
sticky grabs their spaceship
and it isn’t space gum —
it’s the tongue of an E.T.T. —
an Extra-Terrestrial Toad!
When all else fails,
Commander Toad has to
resort to a secret weapon
from his past to save the ship
from “toad-al” destruction.

Spaghettification
What do noodles and spaghetti have to do with black holes? The closer one gets to a black hole,
h the
stronger the pull of its gravity. As the gravity pulls things towards the black hole,
out
hole they get stretched
str
like a long piece of spaghetti. That’s called spaghettification, or the noodle effect.
Here’s what a carrot might look like during spaghettification.
Draw what you think these things might look like if they went through spaghettification.
What’s the
area?
Area is the measure
of how much space
there is on a flat
surface. Practice
calculating area by
measuring the sides
of photographs in the
newspaper. To find
the area, multiply the
length by the height.

The words black and hole are often used in compound words.
Those are words created by combining two smaller words. Use the
words floating in space to create compound words by combining
them with either the word BLACK or the word HOLE.

Do you ever struggle with your
homework? Libraries to the
rescue! Most libraries have
after-school programs to give
one-on-one help to students.
A tutor or a volunteer will
provide personal help with a
school assignment. Some
libraries offer online help. And
for students that perhaps do not
have internet access at home,
some libraries provide reference
sources suitable for students.
This week’s word:
NETWORK
The noun network means
a group or system of
interconnected things.
The network was used
to alert the community
to danger.
Try to use the word
network in a sentence
today when talking with
your friends and family.
