Studying the sun as a star to understand stellar flares and exoplanets — ScienceDaily

New research shows that sunspots and other active regions can change the overall solar emissions. The sunspots cause some emissions to dim and others to brighten; the timing of the changes also varies between different types of emissions. This knowledge will help astronomers characterize the conditions of stars, which has important implications for finding exoplanets around those stars.

An international research team led by Shin Toriumi at the Japan Aerospace Exploration Agency added up the different types of emissions observed by a fleet of satellites including “Hinode” and the “Solar Dynamics Observatory” to see what the Sun would look like if observed from far away as a single dot of light like other stars.

The team investigated how features like sunspots change the overall picture. They found that when a sunspot is near the middle of the side of the Sun facing us, it causes the total amount of visible

Samsung’s Galaxy S20 Ultra and Galaxy Note 20 Ultra might be packed to the hilt with the latest, greatest tech, but they also come with sky-high prices to match. That makes them a tricky sell at a time when purse strings are tightening and rivals like Google and OnePlus are making great phones at more affordable prices.

But the Galaxy S20 FE, which stands for “fan edition,” packs many of the great features of its flagship siblings, including a solid triple camera, a powerful processor, IP68 waterproofing and 5G connectivity, all for a much more affordable price.

At $700 in the US, it’s a hell of a lot cheaper than the Note 20 Ultra, which retails for $1,300 (£1,179, AU$1,849). In the UK and Australia, a 4G version of the S20 FE

Sep 24, 2020 (MARKITWIRED via COMTEX) —
Future Market Insights (FMI) in its recent report projects that the global zoned flash market will be reflecting a stellar CAGR of 36.5% across the 2020-2030 assessment period. The zoned flash devices are gaining popularity worldwide for its role in enhances drive performance as well as enable easy data collection.

The ongoing COVID-19 pandemic has registered a massive surge in cyberattacks incidences with several organizations reported incidences of compromise across online platforms and data theft. Thus, organizations have augmented their expenditure on hardware-based storage devices, offering stellar growth prospects for the zoned flash market. With the complexity of data, assimilation arises every day, prominent players are further leveraging the situation to inflate their market presence.

“Organizations are witnessing an increment in data operation as working hour extends for the employees

Stellar winds hint at how planetary nebulae get their stunning shapes

In their dying throes, some stars leave behind beautiful planetary nebulae — disk, spiral or even butterfly-shaped clouds of dust and gas (SN: 5/17/18).

How these fantastically shaped clouds arise from round stars is a mystery. New observations of red giant stars suggest that massive planets or other objects orbiting dying stars help stir up stellar winds and shape planetary nebulae, researchers report in the Sept. 18 Science.

“We were wondering how stars can get these beautiful shapes,” says Leen Decin, an astrophysicist at KU Leuven in Belgium. So she and her colleagues examined 14 stars in the red giant phase, before they become planetary nebulae. Data from the Atacama Large Millimeter/submillimeter Array in Chile revealed that stellar winds — fast-moving flows of gas, dust and subatomic particles such as protons — ejected from the red giant stars have different shapes, including spirals, disks and cones.

Goldstar Launches Live Events Streaming Platform Stellar

Coronavirus has brought the theater and concert business to its knees. Until there’s a vaccine in place, it’s unclear when people will feel safe returning to Broadway and other live events. That means that many venues and performers face the prospect of months without any income.

Stellar, a new live-streaming service, could provide a lifeline. Now in its beta phase, the system allows producers and artists to sell real tickets to online events, stream to a global audience, and manage payments. Jim McCarthy (pictured above), Stellar’s co-founder, thinks that live-streaming won’t just help theaters weather the current crisis. It could be a boon to their bottom lines even after COVID-19 is no longer a crisis. He sees it as analogous to what the Metropolitan Opera has done by showing filmed versions of its productions in movie theaters, a move that added to its revenues.

“We’re in a crisis,” McCarthy said.
