Scientists finally know how long a day is on Saturn: 10:23:38

Washington, Jan 19 (IANS) NASA’s Cassini spacecraft has revealed that a day on Saturn is just over 10 and-a-half-hours-long, a finding that solved a long-standing mystery of solar system science.

Using new data from the now extinct Cassini mission, scientists led by the University of California-Santa Cruz found that a year on Saturn is 29 Earth years. The day only lasts 10 hours, 33 minutes and 38 seconds.

This was unknown till now because it was hidden in the rings.

Christopher Mankovich, a graduate student in astronomy and astrophysics at the varsity, analysed the wave patterns within the rings.

The findings showed that they respond to vibrations within the planet itself, acting similarly to the seismometers used to measure movement caused by earthquakes.

The inside of Saturn vibrates at frequencies that cause variations in its gravitational field. The rings, in turn, detect those movements in the field.

“Particles throughout the rings can’t help but feel these oscillations in the gravity field,” Mankovich said.

“At specific locations in the rings these oscillations catch ring particles at just the right time in their orbits to gradually build up energy, and that energy gets carried away as an observable wave.”

Mankovich’s research, published in the Astrophysical Journal, describes how he developed models of Saturn’s internal structure that would match the rings’ waves.

That allowed him to track the movements of the interior of the planet, and thus its rotation.

Unlike Jupiter and Earth’s magnetic axis that are not aligned with its rotational axis, Saturn is different. Its unique magnetic field is nearly perfectly aligned with its rotational axis.

This is why the ring finding has been key to homing in on the length of a day.

“The researchers used waves in the rings to peer into Saturn’s interior, and out popped this long-sought, fundamental characteristic of the planet. And it’s a really solid result,” said Cassini Project Scientist Linda Spilker. “The rings held the answer.”

Cassini spacecraft, when low on fuel, made a fateful plunge into the atmosphere of Saturn on September 15, 2017, ending its 13-year tour of the ringed planet.

Today, in collaboration with Vijay Shree Foundation founder Foodman Vishal Singh Ji, I feel immensely proud to dedicate this shelter for the poor, helpless, and needy attendants of patients battling serious illnesses like cancer. I am honored to be associated with the Hunger-Free World Mission for humanity.”

Inspired by the continuous humanitarian service provided by Vijay Shree Foundation over the past 17 years, Nicolle Verma donated 10 lakh rupees to support the cause. The purpose of this donation is to ensure that services continue for the needy attendants of patients suffering from severe illnesses in hospitals, as facilitated by Foodman Vishal Singh.

It is noteworthy that Dr. Abhishek Verma’s family has a legacy of public and philanthropic service. They are helping millions to carry forward the values and service work of their parents. On the occasion of his mother’s birth anniversary, Dr. Abhishek Verma dedicated this state-of-the-art permanent shelter at Lucknow Medical College to serve the attendants of patients through the Vijay Shree Foundation.

Supporting Foodman Vishal Singh’s Hunger-Free World mission, Dr. Abhishek Verma assured that he would continually support keeping this flame of humanity alive. He also promised to assist in providing medicines to the helpless patients.

Continuing her grandmother’s legacy of service, Nicolle Verma personally served food to the needy patients and attendants. She said, “It is our good fortune to have received the joy of doing this noble work today through Foodman Vishal Singh. I have taken another step forward in carrying my family’s values and cooperation by joining hands with the Vijay Shree Foundation. My father taught me to serve and help the needy, and I feel happy when I bring a smile to someone’s face.”

On the birth anniversary of the late Veena Verma, the event organizer, Vijay Shree Foundation founder Foodman Vishal Singh, said, “We feel proud and happy that Dr. Abhishek Verma, a globally renowned business tycoon, has extended his support to uplift our country from the hunger index.
