Solar Plane Lands in U.S. on Record Voyage

The team that's attempting to make the first solar-powered flight around the world completed another milestone Sunday, when its craft landed at Moffett Airfield in California's San Francisco Bay area. Having taken off from Hawaii, this was the ninth leg of the trip and represented the team's first return to the air since last July, after weather and repairs to its plane led to a delay in the project.

At the helm of the Solar Impulse 2 on this leg was Swiss adventurer Bertrand Piccard. The solo pilot had taken off from Kalaeloa, Hawaii, shortly after dawn on Thursday, April 21, completing a journey of 2,200 nautical miles (4,000 kilometers). 

The experimental craft gets all its energy needs from the 17,000 solar panels lining its top, meaning it requires no other fuel. The cells power propellers and charge up batteries that are used for flying during the night.

The team had been waiting for favorable weather

93 Percent of the Great Barrier Reef Is Suffering

Australia’s National Coral Bleaching Taskforce has released its first comprehensive map of the Great Barrier Reef’s bleached corals—revealing that a large portion of the reef has been slightly to severely damaged.

Published after extensive dives and flyovers, the map paints a devastating picture of the damage that the Great Barrier Reef—a 2,300-kilometer string of reefs along Australia’s northeast coast—has sustained in recent months.

The bleaching is caused by abnormally hot waters warmed by El Niño and climate change. The temperatures cause corals’ symbiotic algae—their crucial food source—to short-circuit and become toxic, forcing the corals to expel it. Kicking out the algae t

Animals Rule Chernobyl 30 Years After Nuclear Disaster (New Edition)

It may seem strange that Chernobyl, an area known for the deadliest nuclear accident in history, could become a refuge for all kinds of animals—from moose, deer, beaver, and owls to more exotic species like brown bear, lynx, and wolves—but that is exactly what Shkvyria and some other scientists think has happened. Without people hunting them or ruining their habitat, the thinking goes, wildlife is thriving despite high radiation levels.

Shkvyria is a wolf expert at the Ukraine’s National Academy of Sciences, and one of a handful of scientists following the fate of Chernobyl’s wildlife. She discovered the wolf pack near the village using unorthodox, but cheap, methods. “We came down here late last spring and howled, and the young wolf pups howled back from the top of that hill,” she says with a mischievous smile.

So far, scientists are divided on how well the animals are really doing in the exclusion zone, which straddles Ukrain

The Galaxy Next Door May Be Blowing Giant Double Bubbles

More than 2.5 million light-years from Earth, the Andromeda galaxy is our Milky Way’s de facto twin. The two galaxies carry similar masses and swirl through space with graceful spiral arms.

And if three Russian astronomers are right, Andromeda also shares a surprising skill with the Milky Way: a talent for blowing giant bubbles that glow with gamma rays.

Until now these billowing lobes, nicknamed Fermi bubbles after the NASA telescope used to spot them, had only been seen coming from the Milky Way. And before the bubbles’ inadvertent discovery in 2010, few even suspected such odd cosmic structures existed.

Finding them coming from Andromeda could help scientists figure out how and why galaxies might form the strange twin puffs.

“It could mean that all of th

What Killed the Dinosaurs?

Earlier this month on the Gulf coast of Mexico, an international team began drilling into a vast scar on Earth’s surface. The enormous pockmark, which stretches 110 miles (177 kilometers) wide, was created when a chunk of space rock slammed into the planet about 66 million years ago.

The cosmic smashup isn’t even one of the top five largest hits in Earth’s history, but it holds a special place in our imaginations. That’s because the site, known as the Chicxulub crater, was ground zero for the mass extinction that brought the age of dinosaurs to a close.

While the giant impact is the most likely weapon in this ancient murder case, we know surprisingly little about how the strike translated into widespread death and destruction. Paleontologists have debated aspects of the impact’s ecological fallout ranging from

Alexander the Great

Alexander III of Macedon, better known as Alexander the Great, single-handedly changed the nature of the ancient world in little more than a decade.

Alexander was born in Pella, the ancient capital of Macedonia in July 356 BC. His parents were Philip II of Macedon and his wife Olympias. Alexander was educated by the philosopher Aristotle. Philip was assassinated in 336 BC and Alexander inherited a powerful yet volatile kingdom. He quickly dealt with his enemies at home and reasserted Macedonian power within Greece. He then set out to conquer the massive Persian Empire.

Against overwhelming odds, he led his army to victories across the Persian territories of Asia Minor, Syria and Egypt without suffering a single defeat. His greatest victory was at the Battle of Gaugamela, in what is now northern Iraq, in 331 BC. The young king of Macedonia, leader of the Greeks, overlord of Asia Minor and pharaoh of Egypt became 'great king' of Persia at the age o

Mercury

In astronomy mythology, Mercury was the Roman version of the Greek god Hermes. He was the messenger for the other gods, and for this reason Mercury is often depicted in pictures with winged sandals. In addition to delivering messages, he was also the protector of travelers and merchants. If you moved to Mercury you would not weigh as much as you do on Earth. Not because you would lose weight on the spaceship, but because Mercury is smaller, and so has less gravity. If you weigh 70 pounds (32 kg) on Earth, you would weigh only about 27 pounds (12 kg) on Mercury.

The planet Mercury is the closest of the planets to the Sun. Because this planet lies so close to the Sun, and as a result somewhat near to Earth, it is visible to observers on Earth in the late evening or early morning sky. Because of this, Mercury has become a part of the mythology and legend of almost every culture throughout the history of the Earth.

This planet is often called a morning star. Thi

Solar System

Our solar neighborhood is an exciting place. The Solar System is full of planets, moons, asteroids, comets, minor planets, and many other exciting objects. Learn about Io, the explosive moon that orbits the planet Jupiter, or explore the gigantic canyons and deserts on Mars.

The Solar System is made up of all the planets that orbit our Sun. In addition to planets, the Solar System also consists of moons, comets, asteroids, minor planets, and dust and gas.

Everything in the Solar System orbits or revolves around the Sun. The Sun contains around 98% of all the material in the Solar System. The larger an object is, the more gravity it has. Because the Sun is so large, its powerful gravity attracts all the other objects in the Solar System towards it. At the same time, these objects, which are moving very rapidly, try to fly away from the Sun, outward into the emptiness of outer space. The result of the planets trying to fly away, at the same time that the Sun i

Life On Mars

For centuries people have speculated about the possibility of life on Mars due to the planet's proximity and similarity to Earth. Although there has been much speculation, to date there has never been any proof of life existing on Mars. However, cumulative evidence is now building that Mars once was habitable.

Serious searches for evidence of life began in the 19th century, and they continue today via telescopic investigations and landed missions. While early work focused on phenomenology and bordered on fantasy, modern scientific inquiry has emphasized the search for water, chemical biosignatures in the soil and rocks at the planet's surface, and biomarker gases in the atmosphere.

Mars is of particular interest for the study of the origins of life because of its similarity to the early Earth. This is especially so since Mars has a cold climate and lacks plate tectonics or con

Alexander Graham Bell

Alexander Graham Bell was born on March 3, 1847, in Edinburgh, Scotland. His education was largely received through numerous experiments in sound and the furthering of his father’s work on Visible Speech for the deaf. Bell worked with Thomas Watson on the design and patent of the first practical telephone. In all, Bell held 18 patents in his name alone and 12 that he shared with collaborators. He died on August 2, 1922, in Cape Breton Island, Nova Scotia, Canada.

Alexander Graham Bell was born on March 3, 1847, in Edinburgh, Scotland. The second son of Alexander Melville Bell and Eliza Grace Symonds Bell, he was named for his paternal grandfather. The middle name “Graham” was added when he was 10 years old. He had two brothers, Melville James Bell and Edward Charles Bell, both of whom died from tuberculosis.

During his youth, Alexander Graham Bell experienced strong influences that had a profound effect on his later life. Bell’s hometown o

Bimbo

Bimbo, Bimbo, where you gonna go-i-o?
Bimbo, Bimbo, what ya gonna do-i-o?
Bimbo, Bimbo, does your mommy know,
That you're goin' down the road, to see your little girl-i-o?

Bimbo is a little boy, who's got a million friends.
And every time he passes by, they all invite him in.
He'll clap his hands and sing and dance, and talk his baby that,
With a hole in his pants, and his knees stickin' out, he's just big enough to walk.

Bimbo, Bimbo, where you gonna go-i-o?
Bimbo, Bimbo, what ya gonna do-i-o?
Bimbo Bimbo, does your mommy know,
that you're goin' down the road, To see your little girl-i-o?

Bimbo's got two big blue eyes, that light up like the stars.
And the way to light them up, is to buy him candy bars.
Cracker Jacks and bubble gum will start his day off right.

Last days of Sri Wickrama Rajasingha

The last monarch of the Kandyan Kingdom died on January 30, 1832 thus completing 181 years. The monarch turned out to be a tyrant in the last phase of his rule. When Rajadi Rajasinghe died on July 16, 1798 due to a sudden misadventure, Kannasamy, 18 years of age, looking after the King's Tampala (amarant) garden" (nothoscerua brachiata") was crowned the King of Kandy and ascended to the throne on July 17, 1798 with the full blessings of Pilamatalawa who was the chief of the deceased king's court.

 

This day is significant to us as the first British Governor Frederick North assumed duties in Colombo in October 1798 and there were 29 British Governors up to 1948. This was the year that Ceylon was declared a crown colony. Hugh Cleghorn was the Secretary and three other young Englishmen were brought to assist in the administration of the island.

Now We Are Six

When I was one,
I had just begun.
When I was two,
I was nearly new.
When I was three,
I was hardly me.
When I was four,
I was not much more.
When I was five,
I was just alive.
But now I am six,
I'm as clever as clever.
So I think I'll be six
now and forever.

Puppy And I

I met a Man as I went walking:
We got talking,
Man and I.
"Where are you going to, Man?" I said
(I said to the Man as he went by).
"Down to the village, to get some bread.
Will you come with me?" "No, not I."

I met a horse as I went walking;
We got talking,
Horse and I.
"Where are you going to, Horse, today?"
(I said to the Horse as he went by).
"Down to the village to get some hay.
Will you come with me?" "No, not I."

I met a Woman as I went walking;
We got talking,
Woman and I.
"Where are you going to, Woman, so early?"
(I said to the Woman as she went by).
"Down to the village to get some barley.
Will you come with me?" "No, not I."

I met some Rabbits as I went walking;
We got talking,

Friends

How good to lie a little while
And look up through the tree!
The Sky is like a kind big smile
Bent sweetly over me.

The Sunshine flickers through the lace
Of leaves above my head,
And kisses me upon the face
Like Mother, before bed.

The Wind comes stealing o'er the grass
To whisper pretty things;
And though I cannot see him pass,
I feel his careful wings.

So many gentle Friends are near
Whom one can scarcely see,
A child should never feel a fear,
Wherever he may be.
