Zot lé pa paid for kroir mé lé vré

You asked for this week’s zot lé pa pou kroir menu from Monday July 10 to Friday July 14 here it is: The brightest planet ever detected outside our solar system has revealed its face to astronomers, “Too heavy to take off”. An EasyJet plane had to get rid of 19 passengers. On Monday, snowfall surprised residents of Johannesburg on Monday.
– Like a mirror: Astronomers detect the brightest of exoplanets –
This strange exoplanet, located more than 260 light years from Earth, reflects 80% of the light of its host star, according to new observations from the European space telescope Cheops (CHaracterising ExOPlanet Satellite).
It is the first exoplanet to match the brightness of Venus, the brightest object in our night sky except for the Moon. Discovered in 2020, this Neptune-sized planet, called LTT9779b, orbits its star in just 19 hours.
Can you spot your reflection in this exoplanet?????
Our @ESA_CHEOPS mission has spotted an ultra-hot planet outside of our Solar System which is covered by reflective clouds of metal, making it the shiniest exoplanet ever found.

Due to this proximity, its illuminated face rises to 2,000 degrees, a temperature considered too high for clouds to form. However, the reflectivity of LTT9779b indicated the presence of clouds.
“It was really an enigma”, according to Vivien Parmentier, researcher at the Côte d’Azur Observatory and co-author of a study published in the journal Astronomy and Astrophysics. The researchers then “considered the formation of these clouds in the same way that condensation occurs in a bathroom following a hot shower”, explains the researcher in a press release.
Like the effect of very hot water in a bathroom, a burning current of metal and silicate – the material from which glass is made – supersaturated the atmosphere of LTT9779b until metallic clouds formed. .
LTT9779b is regarding five times the size of Earth and is located in an area that astronomers call “hot Neptune desert”, where planets of this size “should not exist”, summarizes Mr. Parmentier.
Additionally, astronomers expected such a planet to “see its atmosphere blown away by its star” to which it is so close, “leaving bare rock behind.”
They found the explanation: “The metallic clouds of LTT9779b act like a mirror”, reflecting light and preventing the atmosphere from being blown away, according to Maximilian Guenther, chief scientist of the European Space Agency (ESA) Cheops project. .

– Too heavy to take off, EasyJet offers 500 euros to 19 passengers to get off the plane –
“Too heavy to take off”. An EasyJet plane to connect Lanzarote (Spain) to Liverpool (England), Wednesday July 5, 2023 had to get rid of 19 passengers, reports Liverpool Echo. To be able to fly the aircraft, the pilot made an unusual request to the travelers.
“As there are many of you, the plane is quite heavy. Combining a fairly short runway and the unfavorable conditions currently prevailing in Lanzarote, this means that the plane is too heavy to take off”, he began facing the many passengers on the plane.
#easyJet‘s Captain asked 20 passengers to leave the aircraft because it was overweight and wouldn’t be able to takeoff from #Lanzarote due to wind and warm weather. The flight from Lanzarote to #Liverpool was delayed by regarding 2 hours.

But where it gets more amazing is that the pilot added, “I’ve talked to our operations team and the only way to solve a problem with a heavy plane is to make it a little lighter. If possible, I would like to ask 20 volunteers to choose not to fly to Liverpool tonight.”
He supported his request by guaranteeing the sum of “500 euros per passenger”, allocated by EasyJet as a “financial bonus”.
A request confirmed by a spokesperson for the company. To our colleaguesthe man confirmed that “19 passengers on flight EZY3364 from Lanzarote to Liverpool have volunteered to travel on a later flight”.

– Snow falls on Johannesburg… unseen for 11 years –
Johannesburg residents woke up to snowfall lightly covering rooftops and gardens as the cold front that hit the country late last week turned into a weather system called a cold low or ” cut depression”.
At a kindergarten in Johannesburg, children had fun making snowballs and trying to catch snowflakes with their tongues, some for the first time in their lives.
Snow has fallen in Johannesburg…and other areas
“A first since 2012!” A rare phenomenon in South Africa: snowfall surprised the inhabitants of Johannesburg and several regions of the country.

“The last time we had this weather was in 2012,” Puseletso Mofokeng, of the South African Center for Meteorology (SAWS), told AFP.

Seeing snow in Johannesburg, located at an altitude of over 1,700 m, is not unheard of but it remains quite rare. Before 2012, intense snowfall had hit the city in 1996, recalls the meteorologist.
