'Most extreme planet discovered': Scientists find blistering exoplanet with temperatures near 3,200C – National Post
As the study of planets outside our solar system continues, astronomers have discovered what they have described as the ‘most extreme planet’ ever observed, with surface temperatures more blistering than those of some stars.
Researchers at the University of Bern say that the exoplanet, dubbed WASP-189b, is a gaseous giant 1.6 times larger than Jupiter and can record temperatures of up to 3,200 degrees Celsius, hot enough enough to met all rocks and metal and turn them into gaseous form.
The planet, they said, orbits the star HD 133112, known to be one of the hottest stars with a planetary system 2,000 degrees Celsius hotter than our Sun.
Despite being an enormous gaseous giant, WASP-189b is situated much closer to its star than Jupiter is to the sun, and so only take 2.7 days to orbit its star, with one side experiencing a permanent ‘night’ and the other a permanent ‘day’.
“WASP-189b is especially interesting because it is a gas giant that orbits very close to its host star,” astrophysicist Monika Lendl said, according to the university’s press release. “It takes less than three days for it to circle its star, and it is 20 times closer to it than Earth is to the Sun.”
A coronavirus ‘game changer’: Canadian company claims it can detect virus in the air – Global News
Nova Scotia reported one new case of coronavirus on Wednesday, after it was identified the day before.
The province said the new case is in the Northern Zone and is related to travel outside of Canada. The individual has been self-isolating as required, the province said.
Two active cases of COVID-19 remain in the province as of Wednesday, with Nova Scotia Health’s labs having completed 870 Nova Scotia tests the day prior.
When can Canadians expect a COVID-19 vaccine?
To date, Nova Scotia has 94,414 negative test results, 1,088 positive COVID-19 cases and 65 deaths.
One person is currently hospitalized in ICU.
According to the province, 1,021 cases are now considered resolved.
The province’s health officials urge anyone currently experiencing a fever or cough to visit the 811 website to see if an assessment is needed.
If anyone experiences two or more of the following symptoms, they should ask if an assessment is needed:
- sore throat
- runny nose
- shortness of breath
Nova Scotia granted three-quarters of all COVID-19 exemption requests between March and July

Search for life on Mars accelerates as new bodies of water found below planet's surface – National Post
Article content continued
According to the Independent, the MARSIS helped researchers make a previous breakthrough when a large underground lake was found during a study in 2018. However, at that time there was some skepticism regarding the findings and data collected. In order to clearly determine whether the body of water was liquid, researchers felt they needed to investigate further.
To do so, a team led by planetary scientist Elena Pettinelli from Roma Tre University looked to existing methods to study the lakes beneath Earth’s Antarctic glaciers, using satellites in orbit to bounce pulses back and forth. In doing so, they were able to compare data obtained from MARSIS of the area surrounding the body of water found on Mars, which allowed them to confirm that it was in fact liquid. The method also allowed researchers to locate a number of other wet patches around the larger body of water under Mars’s surface, suggesting a number of salty lakes.
“Not only did we confirm the position, extent and strength of the reflector from our 2018 study but we found three new bright areas,” said Professor Pettinelli, who is also an author on the study published in Nature Astronomy.
“The main lake is surrounded by smaller bodies of liquid water, but because of the technical characteristics of the radar, and of its distance from the Martian surface, we cannot conclusively determine whether they are interconnected,” she said in a statement.
The subsurface lakes appear to be “hypersaline solutions” — extremely briney liquid with high concentrations of salt — which may explain why they are not frozen solid, given the extreme cold of Mars’ south pole.
