On July 4, 2016, NASA’s Juno spacecraft arrived at Jupiter traveling at a blistering 130,000 mph. Its mission — to orbit the gas giant closer than any craft had done before — was not easy.
Like Earth, Jupiter is surrounded by a field of magnetic radiation. But Jupiter’s is much, much stronger. If Juno didn’t hit a precise region at the poles where the magnetic field is the weakest in its entry, it wouldn’t have survived; the radiation would have fried the craft.
Juno hit its mark, and Scott Bolton, who leads Mission Juno, called it “the hardest thing NASA has ever done.” Since then, Juno has been completing an orbit of Jupiter once every 53 days.
In June, Juno’s mission was approved to continue through at least July 2021. After that, NASA can choose to extend the mission — or it could end it, plunging the craft into Jupiter’s gauzy atmosphere, where it would burn up. If this dramatic ending sounds familiar, it’s because last year NASA crashed Cassini, the spacecraft that orbited Saturn, into that gas giant. It was awesome.
Scientists believe they’ve solved the mystery of the Bermuda Triange―and it’s not UFOs or sea monsters.
It’s another kind of monster: monster waves.
The Bermuda Triangle, also known as the Devil’s Triangle, is a region in the North Atlantic that is generally bounded by Miami, Bermuda and Puerto Rico. Over time, a number of aircraft and ships are said to have disappeared there under mysterious circumstances.
As Vets Demand Cannabis for PTSD, Science Races to Unlock Its Secrets
Curbs on studies have limited understanding of marijuana’s therapeutic mechanisms, but political pressure and a shift in research could soon shed light
Make a Black Hole
Do words like “general relativity,” “gravity well” and “spacetime continuum” sound intimidating? Don’t worry, you don’t have to be Albert Einstein to understand them! Try this fun activity to learn about these concepts and black holes—using some common household materials.
Let’s start with a quiz…
- How many senses do you have?
- Which of the following are magnetic: a tomato, you, paperclips?
- What are the primary colours of pigments and paints?
- What region of the tongue is responsible for sensing bitter tastes?
- What are the states of matter?
If you answered five; paperclips; red, yellow and blue; the back of the tongue; and gas, liquid and solid, then you would have got full marks in any school exam. But you would have been wrong.
Cervical cancer is the 5th most common cancer in women worldwide with approximately 471,000 new cases diagnosed each year. Approximately every 2 minutes a woman dies of cervical cancer. 80% of the cases occur in low-income or middle-income countries.
Scientists at the Gran Sasso facility will unveil evidence on Friday that raises the troubling possibility of a way to send information back in time, blurring the line between past and present and wreaking havoc with the fundamental principle of cause and effect.
…each of the two beams has as much energy in it as an aircraft carrier underway. If the LHC suddenly lost its ability to keep the beam circling around its vacuum pipe, all that energy would have to go somewhere – with results on the same scale as being rammed by an aircraft carrier.
