To show just how big, Sudbury's Science North has opened a new outdoor exhibit it calls the Sudbury Solar System Path. It's a scale model of the solar system that stretches across the Jim Gordon Boardwalk in Bell Park.
"So we all know how huge the solar system is and how far the planets are," said Julie Moskalyk, Science North's science director.

DNV, an independent energy expert and assurance provider, has issued a Statement of Conformity to Norwegian start-up Sunlit Sea, verifying that the design basis for its floating solar system complies with the recommended practice.
Giant Sunspot AR3038 has Doubled in Size and is Pointed Right at Earth.
Sunspots are typically no real reason to worry, even if they double in size overnight and grow to twice the size of the Earth itself. That’s just what happened with Active Region 3038 (AR3038), a sunspot that happens to be facing Earth and could produce some minor solar flares.
Although scientists consistently point out that people are in no danger from sunspots like AR3038, that doesn’t stop the popular media from worrying about them, especially ones that seem to grow quickly.
SA Water's $300 million solar initiative pumps out another PV system – pv magazine Australia
South Australia utility SA Water has energised another solar PV plant as part of a $300 million solar investment designed to save on both costs and carbon. switching on a 10.3 MW solar system at its Rocky Gully pump station near Murray Bridge in the state's south-east.
SA Water's Zero Cost Energy Future plan to generate about 70% of the electricity it needs to treat water and pump it around South Australia continues to expand, with one of the state's major water pipelines now powered by more than 34,000 solar panels.
Officials detect comet twice as big as Mount Everest approaching Earth | TweakTown
Astronomers have locked on to a comet that is estimated to be twice the size of Mount Everest - comet C/2017 K2.
Researchers have used the Pan-STARRS survey instrument located in Hawaii to hone in on the massive comet.
C/2017 K2 comes with many mysteries that astronomers are yet to figure out, and one of those mysteries is how the comet remains " active " so far away from the Sun. When a comet is "active" it's energized by rays from the Sun that produce that iconic glow and tail on a comet.
Behold the Weird Physics of Double-Impact Asteroids | WIRED UK

When an asteroid strikes a planet, it can pack a powerful punch—as the dinosaurs discovered to their detriment 66 million years ago. But what if two asteroids strike at the same time and in the same location?
A first-of-its-kind study published in the journal Icarus investigates this phenomenon on Mars. Looking at the planet, researchers have discovered hundreds of craters that likely resulted from the impacts of a binary system, where one asteroid orbits another, like the moon orbits Earth.
COSPAR - Committee on Space Research
Fortunately, the Committee on Space Research (COSPAR) is working behind the scenes—and onstage—to safeguard scientific activities in and about space that benefit society today, and to seek applications for the exciting findings in all fields of space research for the 21st century and beyond.
Will Your Solar Panels Work During a Blackout? - CNET
Most solar panels won't work in a blackout. This isn't because they are no longer capable of converting sunlight into electricity, but because of how most solar systems work.
The majority of solar systems are grid-tied systems, meaning they're still attached to the standard utility grid.
Australian Solar Prices: June 2022 Update - Solar Quotes Blog
Which state had the cheapest solar power systems overall last month? Here’s a hint – the initials are WA. Discover what Australians across the country were paying for solar in May 2022.
Cost per watt for fully installed systems including any up-front subsidies and across all system sizes was a mixed bag again in May. There were decreases in Queensland and New South Wales compared to April, and increases in all other states we had sufficient data for at the time of writing.
Hypatia stone: A stone found in Egypt in 1996 could be first evidence of rare supernova explosion ...

"I picked it up, but could tell right away that it wasn't a tektite [a natural glass object formed from terrestrial debris melted by meteorite impact]. It was something unusual, unlike anything I'd ever seen, so I kept it," Barakat tells EL PAÍS.
In the years that followed, Barakat continued to study the stone. Finding little support for his efforts in Egypt, and with limited outside resources at his disposal, he was forced to fund his own travel to laboratories in South Africa where he could analyze the object in more detail.
