The Norhern Lights

Ottawa: A NASA satellite has captured a dazzling infrared image of northern lights that appeared as swirls of glowing clouds over northern Canada on the night of December 22.

In a statement, NASA’s Earth Observatory said that the night after the winter solstice, NASA’s Suomi NPP spacecraft recorded the northern lights, or aurora borealis, across British Columbia, Alberta, Saskatchewan, Manitoba, Nunavut and northwest territories in Canada.

“The collision of solar particles and pressure on our planet’s magnetosphere accelerates particles trapped in the space around Earth. Those particles are sent crashing down into Earth’s upper atmosphere — at altitudes of 100 to 400 km — where they excite oxygen and nitrogen molecules and release photons of light. The results are rays, sheets and curtains of dancing light in the sky,” NASA said in a statement explaining the northern lights.

The solar storms that create the stunning manifestation of the northern lights occur roughly every 11 years.”The last cycle peak occurred in 2013, though NASA researchers reported that solar maximum was the weakest observed in a century,” the report noted.According to a report in Live Science on Wednesday, the satellite’s Visible Infrared Imaging Radiometer Suite captured the northern lights display from 824 km above the Earth.


Zoom saw its popularity soaring in the last three months




“We were humbled by the accelerated adoption of the Zoom platform around the globe in Q1. The COVID-19 crisis has driven higher demand for distributed, face-to-face interactions and collaboration using Zoom. Use cases have grown rapidly as people integrated Zoom into their work, learning, and personal lives,” said Eric S. Yuan, Founder and CEO of Zoom.


While Zoom saw its popularity soaring in the last three months, governments and law enforcement agencies also sought clarification from the video meet app over data hoarding and cyber hoarding, along with issues of unauthorised access termed as “zoom-bombing”.

After the Supreme Court in India sought the response of the Central government over a petition seeking a ban on Zoom, the video calling app claimed that it “takes user privacy, security, and trust extremely seriously.”

“Zoom takes user privacy, security and trust extremely seriously. We have been focused on enhancing our commitment to security and privacy under our 90-day plan announced on April 1, and have made significant progress,” the company said in a statement.

“Our primary grants in Q1 were toward organisations making a difference during COVID-19,” said Yuan.

Zoom growth has led to several tech giants ramping up their video conferencing services like Microsoft Teams, Google Meet and Facebook Messenger Rooms, among others.

Zoom recently announced that it will expand its engineering team with up to 500 new headcount based in Phoenix, Arizona and Pittsburgh, Pennsylvania, in the US.
