TOPICS WE
WILL DISCUSS
SUPERNOVA
What is Supernova??
• A supernova is the explosion of a star. It
is the largest explosion that takes place
in space.
What cause of Supernova?
SUPERNOV
A supernova happens when there is a change in the core, or A
center, of a star. A change can occur in two ways, resulting
in a supernova.
The first type of supernova happens in binary star systems.

The second type of supernova occurs at the end of a single
star’s lifetime.
SUPERNOVA IN BINARY STAR SYSTEMS
Binary stars are the two stars that orbit the same point. One of the stars, a
carbon-oxygen white dwarf, steals matter from its companion star. Eventually,
the white dwarf accumulates too much matter. Having too much matter causes
the star to explode, which results in a supernova.
white dwarf: a star near the end of its life that has used
most or all of its nuclear fuel and collapsed into a size
similar to Earth
SUPERNOVA AT THE END OF A SINGLE
STAR’S LIFETIME
As the star runs out of nuclear fuel, some of its mass flows into its
core. Eventually, the core is so heavy that it cannot withstand its own
gravitational force. The core collapses, which results in the giant
explosion of a supernova.
The sun is a single star, but it does not have enough mass to become
a supernova
BLACKHO
What is Black Hole?
LE
• a black hole is a region where gravity is so strong that
even light cannot escape. Because the matter is
compressed into such a small area, the gravity is
extremely strong. This can happen when the star is
dying.
TYPES OF
BLACKHOLE
Astronomers generally divide black
holes into 4 categories according to
their mass: stellar-mass,
supermassive, intrmediate-mass and
Primordial.
Supermassive blackhole Intermediate-mass blackhole
Thousands - billion times of sun size gap between hundres - thousands

times of sun
Stellar-mass blackhole
Primordial blackhole
Scientist predict Primordial blackhole formed
second after the birth of the universe however
they haven't found it.
20 times the Sun’s mass or more less mass than a mountain and evaporate more
quickly
Parts of blackhole
Black holes have just two main parts which is the Event
Horizon and the Singularity.
The Event Horizon

is the outer limit of the black hole. It is the
closest thing a black hole has to a
surface,which is an invisible bubble in space.
The event horizon is the point of no return.
Nothing can escape a black hole once it crosses
the event horizon
Parts of blackhole
the Singularity
lies right at the heart of the black
hole. It is in this tiny spot that the
entire mass of the black hole is
contained. Anything that falls into the
black hole is eventually crushed onto
the singularity
what causes Black Hole?
• Black holes are made when the
center of a very big star falls in
upon itself, or collapses. When this
happens, it causes a supernova. A
BLACK supernova is an exploding star that
blasts part of the star into space.
HOLE
How does human know
black hole exist
A black hole can not be seen because strong gravity pulls all
of the light into the middle of the black hole. But scientists
can see how the strong gravity affects the stars and gas
around the black hole. Scientists can study stars to find out if
they are flying around, or orbiting, a black hole.
NEWS AND DISCOVERY

News and
discovery
Upcoming supernova
Now, looking far beyond the solar
system, astronomers have added a
solid prediction of an event happening
deep in intergalactic space: an image
of an exploding star, dubbed
Supernova Requiem, which will
appear around the year 2037
Chandra X-ray Observatory identifies new stellar danger to planets
Astronomers have identified a new threat to life on planets like Earth: a

phase during which intense X-rays from exploded stars can affect planets
over 100 light-years away. This newly found threat comes from a
supernova's blast wave striking dense gas surrounding the exploded star.
When this impact occurs it can produce a large dose of X-rays that reaches
an Earth-like planet months to years after the explosion and may last for
decades. Such intense exposure may trigger an extinction event on the
planet. Radiation produced by a supernova in the days and months after
the explosion, and the energetic particles that arrive hundreds to thousands
of years afterward.
Discovery of the earliest known
blackhole
The James Webb Space Telescope has spotted
the earliest known black hole in the universe,
that could have swarmed the young cosmos.
The James Webb Space Telescope discovered

the supermassive black hole, which has a mass
of 10 million times that of the sun, at the
center of a baby galaxy 570 million years after Only
the universe began. ilustration
Astronomers snap 1st-ever direct image of a black hole blasting out a powerful jet
The Event Horizon Telescope captured the historic first photograph of the M87 core
supermassive black hole in 2017. Using data from radio telescopes in Greenland, astronomers
were able to create this new image of M87 and the outflow erupting from it.
Large quantities of stuff, including stars, gas, and dust that approach too closely, are being
consumed by the M87 Blackhole. As a result, these voracious monsters are ejecting powerful
jets of matter that travel at close to the speed of light and occasionally go well beyond the
boundary of the galaxies in which they are found. However, it is unclear exactly how these
supermassive black holes accomplish this.
Trivia and fact
The first supernova(SN 185) was Did you know that in the center of milky was
discovered the year 185 by the galaxy there is a supermassive blackhole
Chinese astronomers called Sagittarius A*
Black Holes Distort Time and Space Around Them If
you happened to fly near a black hole, its extreme
gravitational pull would increasingly slow down time
and warp space
They’re brighter than a galaxy. For a short period of

time, a single supernova can easily outshine an entire
galaxy of stars, releasing as much energy in a single
burst as our Sun will in its entire, 10 billion-year
lifespan.
