From without, the night.
From without the day,
You will do what you do,
And do it your own way.

NASA Astronomy Picture of the Day:

This popular group leaps into the early evening sky around the March equinox and the northern hemisphere spring. Famous as the Leo Triplet, the three magnificent galaxies found in the prominent constellation Leo gather here in one astronomical field of view. Crowd pleasers when imaged with even modest telescopes, they can be introduced individually as NGC 3628 (right), M66 (upper left), and M65 (bottom). All three are large spiral galaxies but tend to look dissimilar, because their galactic disks are tilted at different angles to our line of sight. NGC 3628, also known as the Hamburger Galaxy, is temptingly seen edge-on, with obscuring dust lanes cutting across its puffy galactic plane. The disks of M66 and M65 are both inclined enough to show off their spiral structure. Gravitational interactions between galaxies in the group have left telltale signs, including the tidal tails and warped, inflated disk of NGC 3628 and the drawn out spiral arms of M66. This gorgeous view of the region spans over 1 degree (two full moons) on the sky in a frame that covers over half a million light-years at the trio's estimated distance of 30 million light-years. Of course the spiky foreground stars lie well within our own Milky Way.

Billions of people in the world are living in poverty. Adjusted for the purchasing power in each country, 85% of the world population live on less than $30 per day. 
In an earlier post I said that ‘if we want global poverty to decline substantially then the economies that are home to the poorest billions of people need to grow.’ In this post I want to make this statement more concrete. I will look at the depth of global poverty today to get a quantitative sense of just how much the global income distribution would need to change to reduce global poverty substantially.

Working from home is a dream come true for some people and a nightmare for others. It all depends on your perspective. In the wake of the coronavirus pandemic, some people who started working remotely were happy about the changes. For one thing, working from home saved them time and money that would have been spent on commuting to work every day. 

However, the most important advantage of working from home is that it will keep you safe from getting infected by the novel coronavirus. Right now, this is the only reason that counts. Thankfully, software developers have the privilege of working from home. This has propelled some of them to consider relocation from Silicon Valley to more affordable cities in Texas. 

Tech Talent Flee From Silicon Valley 

Do you know that there are more than 225,300 high tech workers in Silicon Valley, San Francisco? To put this into perspective, there are 387,000 high tech jobs in the entire country. So, if there are 225,300 high-tech jobs in Silicon Valley, then you can understand why it is the best hub for web developers around the world. Unfortunately, the city is at risk of losing its position as the number one destination for tech talent. This is primarily because of two things: talent relocation and company relocation. 

Without the companies and the hundreds of thousands of tech workers in Silicon Valley, the city is going to lose its title as the foremost destination for tech gurus in the United States. This makes it one of the most technologically innovative places in the world but it also makes it one of the most expensive. House rent in the Valley is unrealistically high and it's only going to keep increasing. Tech jobs pay more money than many other jobs in Silicon Valley. However, tech workers aren't satisfied with spending all the money they have on daily expenses. 

A small one-bedroom apartment in Silicon Valley costs over $2,000 monthly. By the time you factor in food and other expenses, you might spend over $5,000 just to survive in Silicon Valley every month. This isn't something the average worker can afford. Some of the tech workers who can afford this expensive lifestyle don't think the Valley is worth all the hype. Since they can now work from home, many of these workers have decided to leave the expensive city for more affordable places.

Why should any average worker pay $5,000 monthly to survive when they spend $2,000 for the same standard of living in another city? The primary reason why many of these tech workers remained in Silicon Valley for this long is because of their jobs. Now that they no longer have to go to the office, they want out of the city. Some of them have already indicated an interest in moving to Texas while many others have moved out already. 

Coronavirus is Changing Tech Salaries 

As tech talent and companies flee Silicon Valley, they inspire even more people to leave the overpriced city. However, tech companies that are remaining in Silicon Valley aren't ready to let their talent relocate, remote work, or not. Facebook and other companies have given their workers ultimatums. They have the choice to remain in Silicon Valley and keep their fat salaries or relocate and face cuts. The salary cuts depend on the company but Facebook is threatening to remove up to 10% of the salary of remote workers. Some other companies claim that they will cut between 8% to 20% depending on where their workers choose to go after leaving the Valley. The cheaper the cost of living in the new place, the higher the salary cut.

Bottom Line 

Covid-19 is changing tech salaries in the United States and every other part of the globe. Many similar things have been happening in tech companies around the world, but the most pronounced rate of relocation is in Silicon Valley. Tech companies like Oracle and Hewlett Packard have also left the Valley for Texas. Even Elon Musk has moved from his Silicon Valley home to the Lone Star State. If companies keep leaving the Valley, it will no longer be the most popular tech hub in the world.

NASA Astronomy Picture of the Day:

Stars fill this infrared view, spanning 4 light-years across the center of the Lagoon Nebula. Visible light images show the glowing gas and obscuring dust clouds that dominate the scene. But this infrared image, constructed from Hubble Space Telescope data, peers closer to the heart of the active star-forming region revealing newborn stars scattered within, against a crowded field of background stars toward the center of our Milky Way galaxy. This tumultuous stellar nursery's central regions are sculpted and energized by the massive, young Herschel 36, seen as the bright star near center in the field of view. Herschel 36 is actually a multiple system of massive stars. At over 30 times the mass of the Sun and less than 1 million years old, the most massive star in the system should live to a stellar old age of 5 million years. Compare that to the almost 5 billion year old Sun which will evolve into a red giant in only another 5 billion years or so. The Lagoon Nebula, also known as M8, lies about 4,000 light-years away within the boundaries of the constellation Sagittarius.

NASA Astronomy Picture of the Day:

Clouds of stardust drift through this deep skyscape, across the Perseus molecular cloud some 850 light-years away. Dusty nebulae reflecting light from embedded young stars stand out in the nearly 2 degree wide telescopic field of view. With a characteristic bluish color reflection nebula NGC 1333 is at center, vdB 13 at top right, with rare yellowish reflection nebula vdB 12 near the top of the frame. Stars are forming in the molecular cloud, though most are obscured at visible wavelengths by the pervasive dust. Still, hints of contrasting red emission from Herbig-Haro objects, the jets and shocked glowing gas emanating from recently formed stars, are evident in NGC 1333. The chaotic environment may be similar to one in which our own Sun formed over 4.5 billion years ago. At the estimated distance of the Perseus molecular cloud, this cosmic scene would span about 40 light-years.

NASA Astronomy Picture of the Day:

If you could stand on Venus -- what would you see? Pictured is the view from Venera 13, a robotic Soviet lander which parachuted and air-braked down through the thick Venusian atmosphere in March of 1982. The desolate landscape it saw included flat rocks, vast empty terrain, and a featureless sky above Phoebe Regio near Venus' equator. On the lower left is the spacecraft's penetrometer used to make scientific measurements, while the light piece on the right is part of an ejected lens-cap. Enduring temperatures near 450 degrees Celsius and pressures 75 times that on Earth, the hardened Venera spacecraft lasted only about two hours. Although data from Venera 13 was beamed across the inner Solar System almost 40 years ago, digital processing and merging of Venera's unusual images continues even today. Recent analyses of infrared measurements taken by ESA's orbiting Venus Express spacecraft indicate that active volcanoes may currently exist on Venus.

Do you have a plan
for your remaining life,
when you battle through
your worry and strife,
to arrive somplace afar,
as you search for answers
of who you really are?

NASA Astronomy Picture of the Day:

In the constellation of the swan near the nebula of the pelican lies the gas cloud of the butterfly next to a star known as the hen. That star, given the proper name Sadr, is just to the right of the featured frame, but the central Butterfly Nebula, designated IC 1318, is shown in high resolution. The intricate patterns in the bright gas and dark dust are caused by complex interactions between interstellar winds, radiation pressures, magnetic fields, and gravity. The featured telescopic view captures IC 1318's characteristic emission from ionized sulfur, hydrogen, and oxygen atoms mapped to the red, green, and blue hues of the popular Hubble Palette. The portion of the Butterfly Nebula pictured spans about 100 light years and lies about 4000 light years away.

NASA Astronomy Picture of the Day:

Yes, but have you ever heard a meteor? Usually, meteors are too far away to make any audible sound. However, a meteor will briefly create an ionization trail that can reflect a distant radio signal. If the geometry is right, you may momentarily hear -- through your radio -- a distant radio station even over static. In the featured video, the sounds of distant radio transmitters were caught reflecting from large meteor trails by a sensitive radio receiver -- at the same time the bright streaks were captured by an all-sky video camera. In the video, the bright paths taken by four fireballs across the sky near Lamy, New Mexico, USA, are shown first. Next, after each static frame, a real-time video captures each meteor streaking across the sky, now paired with the sound recorded from its radio reflection. Projecting a meteor trail down to the Earth may lead to finding its impact site (if any), while projecting its trail back into the sky may lead to identifying its parent comet or asteroid.

NASA Astronomy Picture of the Day:

It appeared, momentarily, like a 50-km tall banded flag. In mid-March of 2015, an energetic Coronal Mass Ejection directed toward a clear magnetic channel to Earth led to one of the more intense geomagnetic storms of recent years. A visual result was wide spread auroras being seen over many countries near Earth's magnetic poles. Captured over Kiruna, Sweden, the image features an unusually straight auroral curtain with the green color emitted low in the Earth's atmosphere, and red many kilometers higher up. It is unclear where the rare purple aurora originates, but it might involve an unusual blue aurora at an even lower altitude than the green, seen superposed with a much higher red. Now past Solar Minimum, colorful nights of auroras over Earth are likely to increase. Follow APOD: Through the Free NASA App
