Scientist Stephen Hawking Dead At Age 76

When we think of scientific geniuses, we may think of Albert Einstein, Marie Curie or Ada Lovelace. Stephen Hawking was right up there with the most brilliant minds of any generation. He passed away last week, at the age of 76.
It would take a book — or a movie (there are both) — to even scratch the surface of his accomplishments, his tremendous sense of humour, his influence on millions of people and the vast depths of his knowledge.

He helped the world better understand black holes and string theory. Black holes are extremely dense regions in space. We can’t see them. In fact, we can understand what they are only by how they affect things around them. Hawking furthered our understanding of them and many other areas of physics. His groundbreaking work changed science forever.

Cave On The Moon Could Be Base For Astronauts

Scientists from JAXA, the Japanese space agency, say they have discovered an enormous underground cave on the moon.

The discovery is exciting because the cave could provide a safe place for astronauts to live and work on future missions to the moon.

In 2009, a lunar probe launched by JAXA sent back images of the cave’s entrance. The probe used radar to determine the underground structures below the entrance and sent the information back to JAXA to be analyzed.

In October, JAXA announced that there appears to be a cavern about 50 kilometres (31 miles) long and 100 metres (328 feet) wide leading from the opening.

Scientists say the cave could make an ideal base for astronauts. It would protect the astronauts and their equipment from the extreme heat and cold on the moon’s surface. It would also help keep them safe from micrometeorites (tiny particles of space dust) that land on the moon, and from the harmful rays of the sun.

Cassini Spacecraft Begins Last Stage Of 20-Year Mission

In October 1997, a spacecraft called the Cassini orbiter was launched on a mission to explore Saturn and its moons.
Now, after nearly 20 years in space, Cassini’s mission is coming to an end. Cassini is running out of fuel. Scientists expect it to burn up in Saturn’s atmosphere in September.
But before that happens, the spacecraft will make a series of dives between Saturn and its rings, sending photographs and other information back to Earth.

Researchers Pay People To Stay In Bed

Getting paid to stay in bed all day sounds pretty good. But what if someone offered you $23,000 to stay in bed for two months? That’s the deal that a medical research team in Toulouse, France, is offering to 24 volunteers.
Researchers at MEDES, the Institute of Space Medicine and Physiology, are looking for volunteers to help them study the effects of weightlessness on the human body by spending 60 days lying down. Lying in bed isn’t exactly the same as being weightless, but the effects on the human body are similar.

NASA Discovery: 7 Earth-Sized Planets

Scientists from NASA announced on February 22 that they have discovered seven planets orbiting a nearby star. The planets are all about the same size as Earth, and three of them are in what scientists call the “habitable zone.”

(The habitable zone is the area of space around a star where a planet is most likely to have liquid water on its surface. Scientists believe water is necessary for anything to live on a planet.)

Astronauts Will Turn Trash Into Tools

Astronauts on the International Space Station (ISS) may soon be able to turn their used forks and knives into tools and satellite parts.
Tethers Unlimited Inc., an aerospace technology company, has developed a system that combines a waste recycling machine with a 3D printer.
Astronauts will put waste items made of plastic into the recycling machine, called the Positrusion Recycler. When they press a button, the Recycler will sterilize and melt down the plastic and turn it into 3D filament.
