New 'mini-moon' set to be captured by Earth might just be space junk – CNET

Does Earth have its second mini-moon discovery in 2020? Unlikely.


NASA

We’ve got one huge moon looming overhead and you might think “that’s enough moons.” But sometimes, Earth gets greedy and starts pulling in small asteroids for extended stays in orbit. The brief visitations by these “mini-moons” are fairly rare, with only two confirmed so far. The most recent came on Feb. 15, when tiny rock 2020 CD3 was discovered by astronomers at the NASA-funded Catalina Sky Survey. The glorious mini-moon had been ensnared by the Earth’s gravity as early as 2015 and stayed with us until May 2020 before dashing off into the cosmos again. 

But in the unprecedented year of 2020, astronomers have announced the detection of another potential mini-moon: 2020 SO. 

Except this one isn’t acting at all like a small asteroid would. Our mini-moon is no moon at all. It’s moving far too slowly for it to be rock ejected from a cosmic body. Therefore, astronomers reason, it’s probably just space junk left over from the early days of the Space Race.

The current theory holds that 2020 SO is the rocket body from an Atlas Centaur-D rocket originally launched in 1966. The rocket lifted off Sept. 20 carrying the Surveyor 2 lunar lander to the moon. The dimensions and the orbit of 2020 SO, published by NASA’s Jet Propulsion Laboratory, seem to align neatly with the Centaur body. 

The object will be grabbed by Earth’s gravitational pull in October and will have its closest approach on Dec. 1, getting to within around 31,000 miles. Astronomers should be able to get a closer look at the object, assessing its shape and the kind of light its emitting. 

If it is the Centaur stage — if it is junk — it’s still interesting junk. It’s been out, wandering the solar system for over five decades. We might be able to learn a little about the effects of space on our old rocket bodies. And while it’s not going to cause any problems for Earthlings, as far as we can tell, it does serve as a timely reminder of the space junk issue.  

Since we first began launching rockets and satellites into orbit, we’ve been polluting space around our planet. Not everything that goes up immediately comes down. There are thousands of pieces of space junk, defunct satellites and tiny chunks of garbage, circling the Earth at great speeds. A collision with a piece of junk could be devastating, blowing a hole right through a rocket or satellite. More launches mean more junk and more junk poses a much bigger risk to spaceflight, satellites and our desire to occupy space.

You don’t even have to look back more than 24 hours to see how the potential issues space debris poses. On Tuesday, the International Space Station had to make a “maneuver burn” to avoid an unknown piece of cosmic trash hurtling toward it.

'Massive' coral reef taller than the Empire State Building discovered in Australia – CTV News

Published

 on


A “massive” new reef measuring 500 metres has been discovered in Australia’s Great Barrier Reef, making it taller than some of the world’s highest skyscrapers.

Scientists found the detached reef, which is the first to be discovered in more than 120 years, in waters off North Queensland while on an expedition aboard research vessel Falkor, ocean research organization Schmidt Ocean Institute announced Monday.

The reef was first discovered on October 20, as scientists completed an underwater mapping of the seafloor of the northern Great Barrier Reef.

At 500 metres high, it is taller than the Empire State Building (381 metres to the top floor), the Sydney Tower (305 metres) and the Petronas Twin Towers (451.9 metres.)

Using an underwater robot named SuBastian, the team explored the reef on Sunday, and live streamed footage of the exploration.

Experts say that the base of the “blade-like” reef measures 1.5 kilometres wide, rising 500 metres to its shallowest depth of 40 metres below the ocean surface.

There are seven other tall detached reefs in the area, including the reef at Raine Island — a significant green turtle nesting site.

Robin Beaman, who led the expedition, said he was “surprised” by the discovery.

“To not only 3D map the reef in detail, but also visually see this discovery with SuBastian is incredible,” he said in a statement.

“This unexpected discovery affirms that we continue to find unknown structures and new species in our ocean,” Wendy Schmidt, co-founder of Schmidt Ocean Institute, said in a statement.

“The state of our knowledge about what’s in the ocean has long been so limited. Thanks to new technologies that work as our eyes, ears and hands in the deep ocean, we have the capacity to explore like never before. New oceanscapes are opening to us, revealing the ecosystems and diverse life forms that share the planet with us.”

The Great Barrier Reef, the world’s largest coral reef, covers more than 214,000 square kilometres and is home to more than 1,500 species of fish, 411 species of hard corals and dozens of other species.

But the reef is facing a crisis — recent studies have shown that it has lost 50% of its coral populations in the last three decades, with climate change a key driver of reef disturbance.

Surrey vet offers tips as Canada reports first COVID-19 case in dog in Ontario – News 1130

Published

 on


SURREY (NEWS 1130) – As Canada’s first case of COVID-19 among dogs is reported in Ontario, a Surrey-based vet is providing some advice to pet owners who may have concerns.

Dr. Sajjid Ijaz with Lifetime Veterinary Clinic says research on COVID-19 in pets is still evolving, but at this point, there’s little evidence to suggest dogs can transmit the virus to humans.

He notes many owners have flagged their COVID-19 concerns with him and his staff over the past few months.

“Obviously, at this point because we do not have any data to give any concrete answers to them, so, we have just been telling them to be careful about going out of their own bubble, as far as their own personal self, as well as the pets themselves. So what we’ve been telling them is to try and limit the pet access to dog parks and all that stuff, and be careful about it,” he explains.

Ontario dog tests positive for COVID-19

A dog in Ontario’s Niagara area has been identified as the first canine to test positive for COVID-19 in Canada. Experts have said this isn’t cause for panic.

The dog apparently belongs to a household where four people tested positive for COVID-19.

Experts told the Toronto Star the dog “had no symptoms and a low viral load, suggesting that dogs remain at relatively low risk of becoming gravely ill or passing on COVID to others.”

Ijaz says while they’re not pushing that message too hard, he and his staff want pet owners to continue to be smart.

Pets and your social bubble

Because of the uncertainty around how the coronavirus is transmitted among pets, Ijaz says it’s wise to apply the same advice to pets when it comes to humans and their social bubbles.

“So, yes, I’ve been telling my clients to limit access, not just totally isolate them, but just to be smart about it,” he explains.

Ijaz understands that pets are often a big part of any family, which is why he believes it’s best to be safe rather than sorry.

“As much as we can limit the bubble, that will help,” he says, adding your social bubble shouldn’t exclude these animals.

According to the World Organisation for Animal Health, there’s been no report of pets spreading COVID-19 to people. There have been reports of possible transmission from mink at a farm in the Netherlands to humans, however, the federal government says this is still being studied.

Hockey Twitter demands a Lunar Classic after NASA reveals moon has a lot more ice than previously believed – Russian Machine Never Breaks

Published

 on


NASA made a special announcement on Monday that had the hockey world buzzing.

“Several studies have showed that water on the moon surface is in its permanently shadowed craters,” Paul Hertz, director of astrophysics at NASA Headquarters, said according to CBS News. “Today, we are announcing that for the first time, water has been confirmed to be present on a sunlit surface of the moon.

It is believed that there are at least 15,000 square miles of the moon’s surface that have deposits of water ice, meaning future astronauts could live off the land.

And Hockey Twitter is hoping those future astronauts are NHL players.

The ridiculousness began early in the day when the NHL on NBC Twitter photoshopped the Blackhawks and Bruins facing off on the moon. “MOON. HOCKEY. 🌕,” they wrote. “We’re ready, @NASA!”

“Call it the Lunar Classic,” the Ducks demanded.

“The Lunar Classic is going to be out of this world!” the Blackhawks added with an excellent pun.

The Hurricanes were excited about some “space hockey.”

So were the Devils.

Later, on their Instagram page, NHL on NBC photoshopped Alex Ovechkin, Roman Josi, and David Pastrnak as astronauts.

Hockey Twitter imagined hockey scenarios on the moon, while another fan, Matthew Henderson, created an elaborate media kit promoting a fake moon hockey event.

I want this to happen so badly now.
