You can take a trip through the solar system this week without ever leaving Earth.
According to a CNN article, though, you can get a look at seven other planets — Mars, Jupiter, Neptune, Saturn, Venus, Uranus and Mercury will all be visible during different times of the day.
The report said that Venus and Mercury will be easiest to see in the mornings. Mars, Jupiter, Saturn and Neptune will be easier to see at night.
The report calls it a “cosmic coincidence.”
So, if you’ve been considering buying a telescope, it’s go-time, and the story said that sales of telescopes have been on sale with an increase of 60-to-400 percent since the pandemic began.
If you have your telescope or are picking one up for the big week ahead, the story recommends that “novice sky watchers,” keep an eye open for Saturn because it, and it’s rings, will be the easiest to pick up in the sky.
Scientists produce diamonds in minutes at room temperature – MINING.com
“Natural diamonds are usually formed over billions of years, about 150 kilometres deep in the Earth where there are high pressures and temperatures above 1,000 degrees Celsius,” Jodie Bradby, professor at The Australian National University and one of the authors of the study, said in a media statement.
“The twist in this story is how we apply the pressure. As well as very high pressures, we allow the carbon to also experience something called ‘shear’ – which is like a twisting or sliding force. We think this allows the carbon atoms to move into place and form Lonsdaleite and regular diamond.”
To observe and understand how this process works, the researchers used advanced electron microscopy techniques to capture solid and intact slices from the experimental samples to create snapshots of how the two types of diamonds formed.
The pictures showed that the regular diamonds only form in the middle of Lonsdaleite veins under this new method.
“Seeing these little ‘rivers’ of Lonsdaleite and regular diamond for the first time was just amazing and really helps us understand how they might form,” Dougal McCulloch, the study’s lead author and a professor at the Royal Melbourne Institute of Technology, said.
According to the scientists, Lonsdaleite has the potential to be used for cutting through ultra-solid materials on mining sites. As such, they said that creating more of this rare diamond is the long-term aim of their work.
Siemens, Deutsche Bahn launch local hydrogen trains trial – The Guardian
MUNICH (Reuters) – Siemens Mobility and Deutsche Bahn have started developing hydrogen-powered fuel cell trains and a filling station which will be trialled in 2024 with view to replace diesel engines on German local rail networks.
The prototype, to be built by Siemens, is based on electric railcar Mireo Plus which will be equipped with fuel cells to turn hydrogen and oxygen into electricity on board, and with a battery, both companies said.
Siemens mobility chief executive Michael Peter told Reuters the train combined the possibility to be fed by three sources in a modular system – either by the battery, the fuel cell or even existing overhead lines, depending on where it would run.
German railway operator Deutsche Bahn has not electrified 40% of its 33,000 kilometre (km) long network, on which it runs 1,300 fossil-fuel emitting diesel locomotives.
Rail transport must be decarbonised over the long-term under European Union and national climate targets.
“Our hydrogen trains are able to replace diesel-fuelled trains in the long term,” Peter said.
The new prototype will be fuelled within 15 minutes, have a range of 600 km and a top speed of 160 km/hour.
It will be tested between Tuebingen, Horb and Pforzheim in Baden Wuerttemberg state.
The main target market are operators of regional networks that typically re-order lots of 10 to 50 trains, Peter said.
“We see a market potential of 10,000-15,000 trains in Europe that will need to be replaced over the next 10-15 years, with 3,000 alone in Germany,” he said.
Each train will cost between five and 10 million euros ($5.9-$11.9 million), creating a market potential of 50-150 billion euros overall.
The Berlin government expects green hydrogen to become competitive with fossil fuels over the long term and to play a key role in decarbonising industry, heating and transport.

The impossible choice Canada’s seniors face this winter – 95.7 News
In today’s Big Story podcast, we want elderly Canadians, who are heightened risk from COVID-19, to be safe. For much of the past eight months, that has meant hundreds of thousands of grandparents haven’t seen their grandkids, parents haven’t seen their children, or their siblings — and for many of them, this has harmed them as much as a bout with the virus might.
We all want our elderly loved ones to be around forever, but even forgetting about COVID-19, they won’t be. And as they face another four to six months without much contact or support, many of them are wondering if they might not choose to take the risk with the time they have left.
