NASA recently released new pictures of Jupiter, the largest planet in our solar system. The photos were taken by the Juno spacecraft. Many of the black-and-white images, sent back to Earth by Juno, have been colourized by people to better show the clouds swirling around the planet. The Juno spacecraft was launched in 2011. Its mission was “to examine Jupiter’s chemistry, atmosphere, interior structure and magnetosophere,” according to a NASA website. Juno arrived at Jupiter in 2016, looking for “clues to its origin and evolution.” Since that time, it has been orbiting (flying around) Jupiter, taking pictures and sending them digitally back to Earth.
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.
Some of the people who created many popular apps are telling kids to put their phones away–at least, a bit more often.
The Center for Humane Technology is made up of people who used to work for big tech companies like Google, Facebook and Twitter. Now they want kids to stop using those apps and websites so much.
In early February the Center, along with Common Sense Media, launched an awareness campaign called the Truth About Tech. Its goal is to teach students, parents and teachers about the dangers of spending too much time on smart phones and tablets.
The January thaw is coming. The term describes unusually warm weather for the time of year–and many people in Canada and the United States should experience it around the end of this month.
Many cities in Canada and the U.S. have been hit with blizzards and extremely cold temperatures, as well as high winds and lots of snow.
Many cities in Canada had snow and temperatures of -20 degrees Celsius (-4 degrees Fahrenheit) or colder. With the “wind chill factor,” -20 degrees Celsius feels like -35 degrees Celsius.
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.
The Cassini space probe’s 20-year mission to Saturn is over. On September 15, at 4:55 a.m. Eastern Time on Earth, the spacecraft entered the atmosphere around Saturn. Moments later, it was destroyed. Cassini was launched in 1997. It had been […]
Everyone is talking about Harvey, Irma, Jose and Katia.
They are the names of very large storms, affecting the area around the Caribbean*, Mexico and the southern United States.
Hurricanes are given names, like “Irma” to make it easier to refer to them.
People in these areas are used to dealing with storms. But these storms are much larger than normal. They have very high winds—up to 120 kilometres an hour—with lots of rain that can flood people’s houses and force them to leave the area. (In this case, leaving your home is known as “evacuating.”) In Florida, more than 6.4 million people have been told to evacuate before Irma gets there, according to a report from CBC News.
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.
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.
Students at public schools in Boston, Massachusetts, will soon be looking at the world in a new way. Social studies teachers there will be using a new type of map that shows the world’s continents in slightly different sizes and positions than we usually see them.
