Stargazers rejoice: Mars to shine its brightest in years this week – CTV News

Published

TORONTO —
Stargazers around the world have the rare opportunity this week to see Mars at its brightest.

According to the NASA Mars Exploration Program, Mars will reach its close approach to Earth on Tuesday night, but should be viewable for several days, depending on weather and viewing conditions. 

The space agency added that Mars should be viewable in the southern night sky and should reach its peak around midnight, but don’t expect to see much more than a speck of light as the red planet is still 62.07 million kilometres away from Earth.

This Mars viewing is especially exciting as the close approach coincides with opposition, which means it is directly on the opposite side of Earth from the Sun and thus the reflection from Mars is at its brightest.

The next Mars close approach isn’t until Dec. 8, 2022,when NASA hopes to take advantage of this shortened distance to land Mars Sample Return, which aims to bring back samples of Mars rocks to Earth for testing.

For those unable to see Mars or want a more up-close look at the red planet, the Allan I. Carswell Observatory at York University has set up a live stream with one of itstelescopes.

The stream runs from 8 p.m. to 10 p.m. on Tuesday night and the same time between Oct. 11 and 15.

Ah Crap: The Arctic Is Releasing a Ton of New Greenhouse Gas – Futurism

Published

Gas Leak

Figuring out when, and to what extent, the Arctic will melt and release greenhouse gases into the air has been a major challenge for environmental scientists. Now it seems like the process is already underway.

A team of Russian and Swedish scientists exploring the Arctic Ocean found that the continental slope near Siberia has already started to give off huge amounts of methane, which is an even more potent greenhouse gas than carbon dioxide, The Guardian reports. The methane, which is leaking into the ocean and the air, is a worrying new data point about the state of the climate.

Early Days

The scientists, who haven’t yet finished analyzing their data or sent it for review by an academic journal, stressed to The Guardian that they’re still at a very preliminary stage of their research. But their discovery is still ominous. If the Arctic is releasing carbon in mass quantities, it could trigger a feedback loop that worsens climate change and continues to give off even more greenhouse gases.

“At this moment, there is unlikely to be any major impact on global warming, but the point is that this process has now been triggered,” Örjan Gustafsson of Stockholm University told The Guardian. “This East Siberian slope methane hydrate system has been perturbed and the process will be ongoing.”

Unknown Impacts

It will be hard to tell what impact these Arctic greenhouse gases will have on the global environment — but the consensus among experts is that it could be disastrous.

“This is a new page,” Igor Semiletov of the Russian Academy of Sciences told The Guardian. “Potentially they can have serious climate consequences, but we need more study before we can confirm that.”

Rare Full Moon Expected on Halloween Night – AM800 (iHeartRadio)

Published

 on


Halloween may seem extra spooky this year thanks to a full moon.

It’ll be visible in every time zone on Saturday, something that hasn’t happened since 1944. 

It’s also known as a “blue” moon, even though the color won’t change.

Scientists use the term to describe the second full moon of the month.

A full moon on Halloween won’t happen again until 2039.
