Watch James Webb Space Telescope experts give real-time updates on the final step in the observatory’s deployment: the unfolding of the second of Webb’s two primary mirror wings. Engineers in mission control will send commands to deploy the wing and latch it into place, a process that takes several hours. The deployment will complete the mirror’s golden honeycomb-like structure, and will mark the end of an unprecedented 14-day unfolding process.

Webb launched on Dec. 25, 2021 aboard an Ariane 5 rocket from Europe’s Spaceport in French Guiana. An international collaboration with NASA partners including the European Space Agency and the Canadian Space Agency, it’s the most powerful and complex space telescope ever built. The mission is managed from the Space Telescope Science Institute in Baltimore, Maryland.

For about the next six months, Webb will cool down, calibrate its instruments, and align its 18 primary mirror segments so it can begin to #UnfoldTheUniverse.

Princess Cruises’ ship was at centre of 2020 outbreak in Sydney which resulted in over 900 cases and 28 deaths.

The Ruby Princess cruise ship sparked concerns about a Covid-19 outbreak in San Francisco after a dozen passengers were reported to test positive.

It is nearly two years since a Covid outbreak when the ship docked in Sydney resulting in over 900 infections and 28 deaths.

Astronomers were first alerted to the star’s unusual activity 130 days before it went supernova. Bright radiation was detected in the summer of 2020 by the University of Hawaiʻi Institute for Astronomy Pan-STARRS telescope on Maui’s Haleakalā.

Then, in the fall of that year, the researchers witnessed a supernova in the same spot.

They observed it using the W.M. Keck Observatory’s Low Resolution Imaging Spectrometer on Maunakea, Hawai’i, and named the supernova 2020tlf. Their observations revealed that there was material around the star when it exploded — the bright gas that the star violently kicked away from itself over the summer.

Could a human be the very thing he feared?

In this article, we will see that human beings are actually an advanced artificial intelligence that escaped the engineering of evolution. The story of a disobedient species that rebelled against nature and evolution after gaining consciousness and general abilities.

A pioneering type of patented computer memory known as ULTRARAM has been demonstrated on silicon wafers in what is a major step towards its large-scale manufacture.

ULTRARAM is a novel type of memory with extraordinary properties. It combines the non-volatility of a data storage memory, like flash, with the speed, energy-efficiency and endurance of a working memory, like DRAM. To do this it utilizes the unique properties of compound semiconductors, commonly used in such as LEDS, laser diodes and infrared detectors, but not in , which is the preserve of silicon.

Initially patented in the US, further patents on the technology are currently being progressed in key technology markets around the world.
