Using the Event Horizon Telescope (EHT) to observe the supermassive black hole at the centre of the galaxy Messier 87 (M87), astronomers have once again produced another first in the field of astronomy and cosmology. Following up on the image of M87’s black hole published two years ago–the first time a black hole was imaged directly–astronomers at the EHT collaboration have captured a stunning image of the same black hole, this time in polarized light.
The academic and activist faction that sets the threatening tone in the climate conversation wants dissent eliminated, leaving themselves the only ones authorized to tell you how scared you should be. To avoid wasting trillions, we should not let them.
We are constantly being warned by activists, politicians, and some climate scientists that we face a climate crisis; that if humanity collectively doesn’t alter its lifestyle and consumption patterns now, the world will end in 10 years, 12 years, 50 years—pick your number.

Rhodium is a silver-white metallic element that is highly reflective and resistant to corrosion. It is considered the rarest and most valuable precious metal in the world — well above gold or silver.

The US “has evidence of UFOs moving at non-human speeds and breaking sound barriers without a sonic boom,” revealed Trump’s former National Intelligence Director, Fox News reported.
Most of the earth’s surface is covered in water, but less than 1% of it is the fresh water that makes up the rivers and lakes we’re familiar with. The water we encounter in life is moving through the stages of the water cycle. And even though rivers make up a tiny portion of all fresh water, they’re still one of the most visible parts of that cycle, especially for the billions of people who live in cities and towns built alongside them.
Mary Mallon was born in 1869 in Ireland and emigrated to the US in 1884. She had worked in a variety of domestic positions for wealthy families prior to settling into her career as a cook.

Despite the UK’s largely successful rollout of the coronavirus vaccine, a public health official says masks and other social distancing restrictions are likely to remain in place for years because the public has become used to them.
According to Reuters, “Sweden, which has shunned the strict lockdowns that have choked much of the global economy, emerged from 2020 with a smaller increase in its overall mortality rate than most European countries, an analysis of official data sources showed.”
CO2 in the atmosphere went up slowly from 1870 to 1970 (290 parts per million, ppm to 320ppm). It then rose a further 70ppm to about 390ppm in 2010. But while CO2 was increasing slowly over that total period, global mean temperatures actually went downtwice in that period (1870 to 1915, and 1940 to 1970).
AstraZeneca may have used “outdated information” in the results of a large-scale COVID-19 vaccine trial, a U.S. health agency said on Tuesday, casting fresh doubt on the shot, its potential U.S. rollout and plunging its developers, once again, into controversy.
A daring drone photographer in Iceland captured breathtaking footage of an unfolding volcanic eruption by flying his UAV over the top of the active crater as lava burst forth high into the air. The amazing footage was reportedly filmed by Bjorn Steinbekk last Friday as the Fagradalsfjall volcano sprung to life following a series of small earthquakes in the country.
