HISTORIC 1ST PHOTO OF BLACK HOLE

A BLACK HOLE

The first images of a black hole, previously thought impossible to capture, was named 'the top scientific breakthrough of 2019' by the journey Science.

What is a black hole?

Black hole are some of the strangest and most fascinating objects found in the outer space. They are objects of extreme density, with such strong gravitational attraction that they eat up everything around them including light. This can happen when a star is dying.

What gives them the enormous power?

Have you ever used vacuum clearer in your home? When you do, watch closely because you will see the dirt and crumbs start moving towards the vacuum clearer. A black hole is similar to vacuum cleaner, cleaning up the debris that is left behind in the outer space. Instead of suction power, a black hole uses the power of gravity to pull things towards it.

How big are black holes?

Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. Another kind of black hole is called 'Stellar.' Its mass can be up to 20 times move than the mass of the Sun. Stellar black hole are made when the center of a very big star falls in upon itself or collapses.

The largest black hole are called 'supermassive.' These black holes have mass that is more than 1 million Suns put together have. The supermassive black hole at the center of the Milky Way Galaxy is called Sagittarius A. It has a mass equal to about 4 million Suns.

Could a black hole destroy Earth?

Black holes do not go around in space, eating stars and planets. Earth will not fall into black hole because no black hole is close enough to the solar system for Earth to do that. The Sun will never turn into black hole. The Sun is not a big enough star to make a black hole.

The first image of a black hole

Since no light can get out, people can't see black holes. They are invisible. Space telescopes with special tools can help find black holes.

The Event Horizon Telescope, a planet-scale array of eight ground-based radio telescope forged through international collaboration, captured the images of the supermassive black hole in the center of the galaxy M87 and its shadow.

The historic photo of a black hole, previously thought impossible to capture, was named 'the top scientific breakthrough of 2019' by the journal Science.

Black holes are objects of extreme density, with such strong gravitational attraction that they eat up everything around them including light. We find them by how they affect their surroundings including the material they heat up around them.

THE GRACEFUL CREATURE OF THE SEAFLOOR

THE GRACEFUL CREATURE OF THE SEAFLOOR The sea pen is graceful creature of the seafloor; this sea pen resembles a plump, old-fashioned quill pen. Its colors range from dark orange to yellow to white. They live at many depths from shallow waters down to deep seas in tropical and temperate water worldwide. Each sea pen is a colony of polyps, small anemone like individuals working together for the survival of the whole. The primary polyp loses its tentacles and becomes the stalk of the sea pen with a bulb at its base. The bulb anchors the sea pen in the muddy or sandy bottom. They feed on phytoplankton and detritus particles. The red star, the leather star and the three types of Nudibranchs prey on sea pens. When touched, sea pens emit a bright greenish light; this is known as bioluminescence. when disturbed, a sea pen forces water out of the colony, making it possible for them to retreat into its bulbous foot. Recent research shows that the population of Sea pen has declined in some areas...

THE FORGOTTEN SCIENTIST

NIKOLA TESLA Nikola Tesla was the famous scientist of 19th century. Nikola Tesla was born on 10th July 1856 in Smiljan, Austria (modern-day Croatia Southeast Europe). His father Milutin was a priest of the Serbian Orthodox Church. From early age, he could memorize entire books and store logarithms table in his brain. At the age of 19, he was studying electrical engineering at Polytechnic Institute at Gray in Austria. Tesla's general IQ was in a range from 160 to 200. Average Nikola Tesla IQ was 180. He made dozens of breakthrough in the production, transmission and application of electric power. He invented the first alternating current (AC) motor and developed AC generation and transmission technology. Though he was famous and respected, he was never able to translate his copious inventions into long-term financial success. In 1884, Tesla arrived in New York and was hired as an engineer at Thomas Alva Edison's Manhattan headquarters. After seeing his ingenuity, Edison told T...
