This month marks 40 years since NASA launched the two Voyager space probes on their mission to explore the outer planets of our solar system, and Australia has been helping the US space agency keep track of the probes at every step of their epic journey.
There are eight planets in our solar system (sorry, Pluto), and each has a unique story. Come visit every one from mini Mercury to mysterious Neptune.
1. Is it bad for countries to specialize? 2. Why you should visit Macedonia. 3. Ilya Somin on Confederate monuments. 4. “Now you can levitate liquids and insects at home.” Here is the study. 5. A tour of our solar system’s eclipses. The post Wednesday assorted links appeared first on Marginal REVOLUTION.
In a meditative video for the NY Times, Dennis Overbye takes us on a tour of eclipses that happen in our solar system and beyond. On the 21st day of August, 2017, the moon will slide between the Earth and the sun, painting a swath of darkness across North America. Show More Summary
On 14 October 2014, our Sun let out a great big burp, a coronal mass ejection that swept through the Solar System at an incredibly fortuitous angle. Several spacecraft (and one intrepid Martian rover) detected the solar blast, resulting in an unprecedented experiment that stretched all the way from Venus to outer reaches of the Solar System.

Casually Explained stops talking about love and life for a moment to dish out some hard science. Fiction. Watch his breakdown of our celestial neighborhood, which includes Earth’s hot sister, Elon Musk’s homeworld, and yo momma.
Of the many factors that must come together on a planetary body to allow the possibility of life as we know it, the age of the parent star is also an important one.
The planetary system is located 40 light years away from Earth and is viewed as a candidate for finding life outside our solar system.
If we want to know more about whether life could survive on a planet outside our solar system, it's important to know the age of its star. Young stars have frequent releases of high-energy radiation called flares that can zap their planets' surfaces. Show More Summary
"If there is life on these planets, I would speculate that it has to be hardy life, because it has to be able to survive some potentially dire scenarios for billions of years," said Adam Burgasser, University of California, San...
Two years ago, NASA’s New Horizons revolutionized our appreciation of Pluto and its moons. The little probe is still functioning and speeding out of the solar system into interstellar space at 10 miles a second. But before it fades into the cosmic night forever, it will reconnoiter an enigmatic Kuiper Belt Object called 2014 MU69. Show More Summary
Exoplanets seem to be a dime a dozen these days, but rarely are they as promising as a pair of newly-discovered worlds orbiting a star called Tau Ceti. The star, which is a lot like our own sun, is remarkably close to our solar system,...Show More Summary
Scientists have helped solve the mystery of what lies beneath the surface of Neptune – the most distant planet in our solar system. A new study sheds light on the chemical make-up of the planet, which lies around 4.5 billion kilometres from the sun.
(University of Edinburgh) Scientists have helped solve the mystery of what lies beneath the surface of Neptune -- the most distant planet in our solar system.
August 20, 2017 marks the 40th anniversary of the launch of the the first NASA Voyager mission, which is carrying a golden record filled with messages to potential civilizations beyond our solar system. This year is also the 20th anniversary of the sci-fi film Contact that dealt with our receiving radio messages from extraterrestrials. Show More Summary
Two potentially habitable "super-Earths" orbit a star just 12 light years away that is our nearest sun-like neighbour, scientists have discovered. The worlds at the edges of Tau Ceti's "habitable zone" belong to a solar system of four rocky planets similar in size to Earth. Show More Summary
Your words could reach out of our solar system—no gigantic megaphone necessary. NASA is hosting a contest that will see a message from one lucky Earthling sent to Voyager 1, which is hurtling through interstellar space. Entrants are invited to submit an "uplifting" message of 60 characters or less...
Our solar system contains a very large main asteroid belt between Mars and Jupiter, an orbiting mass of tens of thousands of rocky fragments that have orbited the Sun for billions of years. Within the belt there are some larger objects—such...Show More Summary
(Massachusetts Institute of Technology) A NASA mission designed to explore the stars in search of planets outside of our solar system is a step closer to launch, now that its four cameras have been completed by researchers at MIT.
According to one longstanding theory, our Solar System's formation was triggered by a shock wave from an exploding supernova. The shock wave injected material from the exploding star into a neighboring cloud of dust and gas, causing it to collapse...
