New, high-resolution observations of a faint, fluffy galaxy suggest that dark matter’s not as ubiquitous as scientists thought.
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 photonic devices such as LEDS, laser diodes and infrared detectors, but not in digital electronics, 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.
On January 6, 2022, a Tesla Model S P85 (the oldest performance version) reached an impressive mileage milestone of 1,500,000 km (932,256 miles).
The car is used in Germany by Hansjörg von Gemmingen — Hornberg, who is known in the EV world for setting the highest mileage records in Tesla cars.
New anti-corrosion coating increases the economic life and durability of steel machinery.
A wind turbine sitting idle on a calm day or spinning swiftly when power demand is already met poses a problem for renewables, and is one researchers think can be tackled under the sea.
In one vision, offshore wind farms could use seawater to essentially store energy until it’s needed, helping wean humanity off fossil fuels.
“We came up with a solution that we call the ocean battery,” Frits Bliek, CEO of Dutch startup Ocean Grazer told AFP while showing off the system at the CES tech fair in Las Vegas.

In the two weeks since its launch on December 25 at 7:20 am ET, Webb has successfully completed many milestones:
✨ Webb released and deployed its solar array, which means the telescope went off battery power and began to use its own generated power.
✨ Webb has had two planned mid-course correction burns. Webb was launched on a direct path to an orbit around the second Lagrange Point (L2), but its trajectory required correction maneuvers to get there.
✨ The 5-layer sunshield has been fully deployed and tensioned. Did we mention it is the size of a tennis court? 🤯
✨ Webb’s secondary mirror, which plays an important role in reflecting light collected by the primary mirror into the telescope’s instruments, has been deployed.
