Over the years I have written four letters to The New York Times.Two of them were published which shows that my view points were taken into consideration.

Mars' dust devils!

While dust devils aren’t exactly uncommon on Mars — the Red Planet is, after all, a very dusty and windy place — the whirlwinds often fade almost as quickly as they appear. That makes capturing an image of one in action a rare treat.

But in October 2019, NASA’s Mars Reconnaissance Orbiter managed to snap a photo of a massive active dust devil — and you can now see it for yourself.

A painting under a painting!

The Leonardo da Vinci painting the "Virgin of the Rocks" was hiding another image beneath its surface: a winged baby Jesus, a new X-ray examination has revealed.

This isn't the first signal that the "Virgin of the Rocks" hid older sketches that might have led to a different masterpiece. A similar effort, using infrared light in August 2019, revealed a sketch of a different Virgin Mary posed higher in the frame, as Live Science previously reported. But this new scan of the painting using a technique called macro X-ray fluorescence (MA-XRF) —  as well as a new algorithm to interpret the data — revealed the head and wings of this unseen baby Jesus.

Th Elgin Marbles!

In 1801 a British nobleman stripped the Parthenon of many of its sculptures and took them to England. Controversy over their acquisition by the British Museum continues to this day. Was it preservation, or pillage?

The Monarch Butterflies!

Monarch butterflies travel as much as 100 miles a day during its 3,000-mile migration south. During its migration, each butterfly relies on the huge volume of food it ate when it was a caterpillar for fuel. Monarchs smell with their antennae. Nectar and water are tasted by the sensory hairs on their legs and feet.

Return to Earth!

NASA astronaut Christina Koch will return to Earth Thursday (Feb. 6) after spending 328 days on the International Space Station — a new record for the longest single spaceflight by a woman.

After almost a year in space, Koch has conducted numerous science experiments on the orbiting lab, including studying the effects of microgravity on Mizuna mustard greens, combustion, bioprinting and kidney diseases.

In addition to her science experiments on the space station, Koch's extended mission will allow researchers to study the effects of long-duration spaceflight on a woman. This research will benefit future missions to the moon under the Artemis program and Mars. Sourse: Space.com

Quarantined Ship!

Things were looking up on Thursday for the more than 2,000 passengers quarantined on a cruise ship in Yokohama, Japan: Meals were coming on a more regular schedule. The internet was upgraded to a wider bandwidth. And there was even official approval to breathe some fresh air.

Still, on the second day of a planned two-week quarantine, there was persistent concern about the spreading coronavirus and dread about long days ahead stuck inside the cabins.

As Japanese health officials continued to screen 273 passengers who were potentially exposed to the virus, they said that 20 of the 102 tested so far had been found to be positive.

The first 10 cases were announced on Wednesday, and the second 10 on Thursday. The new cases involved four Japanese passengers, two Americans, two Canadians, one New Zealander and one Taiwanese. They were removed from the ship on Thursday and taken to medical facilities.

The International Space Station!

The International Space Station is the largest structure ever built in space.

The first module — the Russian Zarya module — launched from Earth 15 years ago on Nov. 20, 1998. International crews have continuously occupied the orbiting space laboratory since 2000, and five space agencies contributed to the building of the structure.

The $100 billion International Space Station has the wingspan of a football field and the living space of a five-bedroom house. It took more than 115 spaceflights of different kinds of spacecraft to build the station, and astronauts and cosmonauts have spent more than 1,000 hours on spacewalks outside of the station.

Scientists: The Coronavirus May Be More Contagious Than Thought
There’s a growing body of evidence suggesting that 2019-nCoV, the coronavirus that’s caused a global outbreak this year, could be even more infectious than scientists and health officials originally thought. A week ago, there were just shy of 6,200 confirmed cases of the virus worldwide — a number that has more than tripled since. Source Futurism.com

Self Driving cars!

 A self-driving company Cruise, a Honda-backed General Motors subsidiary, has unveiled an SUV-sized vehicle called “Origin” that’s been designed from the ground up to never have a driver, The Verge reports.

“We built this car around the idea of not having a driver and specifically being used in a ride-share fleet,” Cruise co-founder Kyle Vogt told The Verge. Source: Futurism.com

Coronavirus latest news!

Nine passengers and one crew member on a cruise ship quarantined in Yokohama, Japan, have tested positive for the coronavirus, the cruise line, Princess Cruises, said on Wednesday.

The ship, carrying 2,666 passengers and 1,045 crew members, arrived in Yokohama on Tuesday, but the authorities did not allow anyone off. An 80-year-old Hong Kong resident who had disembarked earlier in his home city was found to be infected.

In all, 273 passengers were tested for the virus after everyone on board underwent an initial health screening. Twenty-one people were cleared, and officials were awaiting the other results. Source: New York Times.
