Uranus and Mars will be visible close together in the night sky tonight, January 21, 2021.

Look up tonight (Jan. 21) to see Uranus and Mars nestled together in the night sky — just don’t forget your binoculars.

Yesterday (Jan. 20) on Inauguration Day in the U.S., the two planets were in conjunction, meaning they appeared very close together in the sky. Tonight, the planets will share the same “right ascension,” with Mars passing just 1.75 degrees to the north of Uranus, according to Earthsky.org. (Your fist held at arm’s length covers about 10 degrees of sky.) The moon will also be shining nearby, making it a good landmark to start from when looking for the planets.

Uranus, the seventh planet in our solar system, which orbits 1.8 billion miles (2.9 billion kilometers) from the sun, will be at a magnitude 5.8 in the sky. Meanwhile, Mars, the fourth planet from the sun, which orbits at an average distance of “just” 143.6 million miles (231.1 million km), will be visible at magnitude 0.2. 

The brightest planets in January’s night sky: How to see them (and when)

The lower the magnitude number a cosmic object has, the brighter it is (there are even seriously bright objects with negative magnitudes), so Mars will be significantly brighter in the sky than Uranus. But, while Uranus will be tough to spot, both will still be visible with the help of binoculars, though the planets will be too far separated to fit within a telescope’s field of view, according to in-the-sky.org

To try and find Uranus, first “find the crescent moon and the Red Planet in the couple of hours after it gets dark. Scan your way over from Mars toward the moon, and you should be able to find the faint, bluish disk of Uranus,” NASA’s Jet Propulsion Laboratory said in its monthly “What’s Up” skywatching series. 

Now, while Uranus and Mars will be putting on this show in the night sky, they won’t be the only planets hanging out tonight. Both Jupiter and Saturn are still officially in the evening sky, though the light from the setting sun makes it so they are not visible, according to Earthsky.org.

Earth from Space

“Planet Earth Report” provides descriptive links to headline news by leading science journalists about the extraordinary discoveries, technology, people, and events changing our knowledge of Planet Earth and the future of the human species.

Abigail Allwood’s Hunt for Alien Fossils on Mars Has Begun, reports Isaac Schultz for Gizmodo –When the NASA Mars rover Perseverance was dramatically airlifted through the Red Planet’s atmosphere and touched down on the iron-rich soil, geologist and astrobiologist Abigail Allwood was at home on Earth, watching the events unfold via livestream like the rest of us. Speaking over the phone the next day, her thought process was probably similar to yours: “Amazing—talk about incredible,” she said. “Excitement yesterday about landing and today about the landing site.” But in the months to come, Allwood will have a unique charge, one that years of terrestrial study have prepared her for: seeking out life on Mars.

The Secret Life of a Coronavirus –An oily, 100-nanometer-wide bubble of genes has killed more than two million people and reshaped the world. Scientists don’t quite know what to make of it, reports Carl Zimmer for the New York Times. ”
Nature was expanding as billions of people were retreating from the Covid-19 pandemic. The change was so swift, so striking that scientists needed a new name for it: the anthropause.”

The six numbers that define the entire Universe, reports BBC Science Focus –In this edited extract from The Little Book of Cosmology, physicist Prof Lyman Page explains how our model of the Universe relies on just six parameters.”The first three parameters tell us about the contents of the Universe. We describe them as fractions of a total matter and energy budget, like the components of a pie chart. The first parameter describes the amount of normal matter, or atoms, in the Universe, and it says that atoms account for just 5 per cent of the Universe. The second parameter describes dark matter, some type of new fundamental particle that we do not yet understand, which accounts for 25 per cent of the Universe.”

‘Space hurricane’ observed above the North Pole –The space hurricane was detected in the Earth’s upper atmosphere and ‘rained electrons’ over the North Pole for nearly eight hours, reports Science Focus.

Earth’s Hidden ‘Innermost-Inner’ Core –“May Reveal an Unknown, Dramatic Event in the Planet’s History”, reports The Daily Galaxy. “We found evidence that may indicate a change in the structure of iron, which suggests perhaps two separate cooling events in Earth’s history,” said Joanne Stephenson, a researcher from The Australian National University (ANU), about the confirmation of the existence of the Earth’s “innermost inner core” that may point to an unknown, dramatic event in the Earth’s history.

“The Methuselah Dilemma” — Atacama Cosmology Telescope Resolves True Age of Our Universe, reports The Daily Galaxy. In 2013, the Hubble Space Telescope found the birth certificate of oldest known star in the universe, cataloged as HD 140283, aptly named “methuselah”. The star, located in the constellation Libra, which is at the very first stages of expanding into a red giant, could be as old as 14.5 billion years (plus or minus 0.8 billion years), which at first glance would make it older than the universe’s calculated age of about 13.8 billion years, creating what we commonly call a dilemma.

The Moon Has a Comet-Like Tail. Every Month It Shoots a Beam Around Earth, reports Robin George Andrews for The New York Times –“It almost seems like a magical thing,” said one of the astronomers involved in studying the lunar phenomenon.

Surface Bubbles Could Have Evolved into Earth’s First Cells –Artificial “protocells” suggest the complex biochemical mechanisms used by living cells could have originated in simple bubbles, reports Inside Science.

How our abuse of nature makes pandemics like covid-19 more likely –From habitat degradation to squalid animal treatment, our part in allowing “zoonotic” diseases like covid-19 to leap into humans is becoming ever clearer, reports New Scientist.

Neanderthals Listened to the World Much Like Us –A reconstructed Neanderthal ear adds a new piece to the puzzle of whether the early humans could speak, reports The New York Times.

One of the largest ecosystems on Earth lives beneath the seafloor and eats radiation byproducts, reports ZME Science.

Butterflies are vanishing out West. Scientists say climate change is to blame. –The rate of decline is “calamitous,” one scientist said, and has implications for crops and the environment, reports The Washington Post.

India’s revolutionary sustainable roads –From lower carbon emissions to fewer potholes, there are a number of benefits to building a layer of plastic into roads, reports Chermaine Lee for BBC Future

Did Woolly Mammoths Overlap With First Humans in New England? asks Amy Olson for Dartmouth News/
Researchers trace the age of a Mount Holly mammoth rib fragment from Mount Holly, Vt. –“It has long been thought that megafauna and humans in New England did not overlap in time and space and that it was probably ultimately environmental change that led to the extinction of these animals in the region, but our research provides some of the first evidence that they may have actually co-existed,” says co-author Nathaniel Kitchel.

Strange Earthquakes in Utah Reveal Volcanic Activity Hidden Below The Desert, reports ScienceAlert –It might not look like it, but the arid expanses of Utah conceal an ancient volcanic complex, and this hidden underground system is still active far below the desert’s surface, scientists say.

Largest Glowing Shark Species Discovered Near New Zealand –It’s the biggest bioluminescent vertebrate found on land or sea, so far, reports The New York Times.

Dr. Vera Etches says it seems Ottawa's 3rd COVID-19 wave is coming – CBC.ca

Published

 on



Ottawa’s medical offficer of health said Friday it seems the city’s third wave is coming, and is asking people to maintain physical distancing to prevent a surge in COVID-19 cases.

“It looks like [a third wave] is coming. It’s apparent in the wastewater and that’s been a pretty reliable predictor,” said Dr. Vera Etches in an interview on CBC Radio’s Ottawa Morning.

Etches said the spread is being driven in social settings and people can’t get complacent with behaviour such as distancing and wearing masks because of positive news about vaccines.

It will still be a few months until vaccination has an impact on the general population, she said.

On Wednesday, Ottawa Public Health (OPH) warned it’s seeing a rise in the number of people believed to have one of the more contagious variants.

People testing Ottawa’s wastewater for the coronavirus began seeing an increase in the back half of February. (613covid.ca)

So far, 10 people have tested positive for variants of concern first identified in the United Kingdom and South Africa.

But according to Etches, 73 more people have a genetic indicator after initial screening that could signal they’ve contracted one of the variants and wastewater testing also suggests there could be more.

WATCH | Dr. Vera Etches on Ottawa Morning:

The health authority also said some the city’s key indicators, used to track the spread of the virus, are also trending closer to the red zone on the province’s pandemic scale.

Such a move would mean stricter restrictions such as smaller gatherings and sports being limited to practices.

At the same time, vaccine appointments were made available to more Ottawans this week.

Eastern Ontarians get a pricey taste of high-speed internet with Elon Musk's Starlink – CBC.ca

Published

 on


It might be expensive, but to get rid of his shoddy internet, it’s a price Darren Boss is willing to pay.

Three years ago, Boss and his wife moved from Ottawa to just outside Perth, Ont., and until recently they’d been dealing with spotty, unreliable internet — a problem facing countless rural Canadians, and a big obstacle for the couple given they both work in IT.

They’d often have to schedule their video work meetings so they weren’t competing at the same time for a reliable connection. Boss said they tried several providers and had the same experience every time.

That’s why the pair decided to sign up for Starlink, the new pricey high-speed internet service provided by Elon Musk’s U.S.-based SpaceX firm, which was recently approved by the Canadian Radio-television and Telecommunications Commission (CRTC).

The service is available to select users for “beta testing,” with the promise of wider availability this year. Boss received his satellite a few weeks ago and said so far, the results have been promising.

“I changed the way I did some of my job just because of how slow the upload speeds were and now I don’t have to make those compromises anymore,” Boss said.

But he admits it’s expensive. Boss paid $800 for the satellite equipment alone, and $150 a month for the service itself.

“I feel pretty grateful to have this opportunity,” he said. “And I feel lucky that we could afford to get the service.”

Potential game-changer

North Grenville, Ont., Mayor Nancy Peckford has been a long-time advocate of better internet access for rural municipalities and said Starlink is a potential game-changer.

Connectivity standards from CRTC include speeds of 50 Mbps download/10 Mbps upload for fixed broadband services. At those speeds, multiple members of a household should be able to stream, download and upload with no concerns

According to Peckford, however, recent tests in her community showed speeds significantly “below the CRTC minimum rate.”

“It’s very, very distressing. I mean, you’re looking at upload [and] download speeds that are a fifth of what you might see in an urban area,” she said.

Still seeking other investments

While Starlink isn’t “necessarily affordable” for those it was made for, Peckford said that “desperate times sometimes require desperate measures.”

She said a handful of North Grenville residents have signed up with Starlink, and the town is watching the results very closely.

Despite Starlink’s availability, North Grenville and other nearby municipalities are still working with the provincial and federal governments, Peckford said, on other infrastructure investments.

“I don’t think it’s the end all, be all,” she said. “But I would also suggest that many of our residents are welcoming it, and our businesses, with open arms — and rightly so.”
