The new German tanks like the Panther, Ferdinand and King Tiger would pose a serious threat to the steady flow of T-34 s coming out from the factories in ever increasing numbers. But the Soviet designers had several aces in their sleeves. New tank and SPG designs like T-34-85, SU-85, SU-100 were coming in, tipping the balance to the Soviet side. Was the T-34-85 the best tank of the WWII? What advantages and disadvantages did the design have? How did it fare compared to the German tanks? How did the largest tank battle of WWII end?

Did Mars long ago develop far enough for life to arise? If so, does anything still live within Mars dusty plains, beneath its ice caps, or somewhere underground? In 1964 the Mariner Four spacecraft flew by Mars and got a good look. What it saw looked more like the Moon than the Earth. Then, in the mid-1970 s, two lander-orbiter robot teams, named Viking, went in for an even closer look. The landers tested the soil for the chemical residues of life. All the evidence from Viking told us: Mars is dead. And extremely harsh. The mission recorded Martian surface temperatures from -17 degrees Celsius down to -107. We now know it can get even colder than that at the poles. The atmosphere is 95% carbon dioxide, with only traces of oxygen. And it s extremely thin, with less than one percent the surface pressure of Earth s atmosphere. And it s bone dry. In fact, the Sahara Desert is a rainforest compared to Mars, where water vapor is a trace gas in the atmosphere. On Earth, impact craters erode over time from wind and water... and even volcanic activity. On Mars, they can linger for billions of years. Earth s surface is shaped and reshaped by the horizontal movement of plates that make up its crust driven by heat welling up from the planet s hot interior. At half the width and only 11% the mass of Earth, Mars doesn t generate enough heat to support wide-scale plate tectonics. Nor does it have the gravity to hold a thick atmosphere needed to store enough heat at the surface to allow liquid water to flow. Nonetheless, some areas that looked to Viking-era scientists like craters and volcanic areas, were later shown to be riverbeds, lake bottoms, and ocean shorelines. If water once flowed on Mars surface, where did it all go? This was the scene at NASA s Jet Propulsion Lab in 2004. The twin rovers Spirit and Opportunity had just bounced down on the Red Planet. When the excitement died down, the rovers were set off on one of the most remarkable journeys in the history of planetary exploration. Missions like this could one day pave the way for a day when we ll view images from a real astronaut s camera. Opportunity had come to rest in a small crater near the equator, at a spot called Meridiani Planum. Here, in plain view, on a nearby crater wall, its camera revealed exposed bedrock, the first ever seen on Mars. Not far away, the rover found layered rocks on the face of a cliff. On Earth, they typically form as sedimentary layers at the bottom of oceans. And at every turn, Opportunity rolled across tiny, smooth, round pellets. They became known as "blueberries" because they appeared purplish-brown against Mars rust-colored surface. Initially thought to be volcanic in origin, they turned out to be iron-rich spherules of the type that form within cavities in the mud at the bottom of an ocean. Drilling into rocks, the rover inserted a spectrometer to read the mineral content. The readings showed significant amounts of sulfate salt, a tracer for standing water. That wasn t all. Spirit s broken wheel, dragging behind it, exposed soils saturated in salt. Clearly there once was water on Mars surface, but how long ago? And, if there is anything left, where would you find it? One possible answer: the North Pole. From orbit, this region seemed to be covered in frozen CO2 - what we call dry ice. But was there water ice below the surface? Enter Phoenix, a lander that touched down near the North Pole in early 2008. Radar readings from orbit, taken by the Mars Express mission, hinted at the presence of ice just below the surface. The Phoenix lander s descent thrusters blew away the top layer of soil, allowing its camera to snap pictures of what looked like ice. Scientists instructed the robot to conduct a simple experiment: reach out and dig a trench, then watch what happens. As expected, clumps of white stuff appeared. A couple of days later, it was gone. Vaporized. That means it can t be salt or frozen CO2, which is stable in the cold dry temperatures of the Martian pole. So it had to be water, the first ever directly seen on Mars. There are indications that the North Pole was actually warm enough in the recent past for water ice to become liquid. The Mars Reconaissance Orbiter, or MRO, used radar pulses to peer beneath the surface of the ice cap. These data reveal that the ice, just over a mile thick, formed in a succession of layers as the climate alternated between warm and cold. Our planet avoids mood swings like this in part because its spin is stabilized by a massive moon. Mars spin is not, so it can really wobble, with the pole tilting toward the sun for long periods. New observations by the MRO spacecraft show that these wobbles can lead to dramatic releases of CO2, and warming periods due to an increase in the greenhouse effect.

Astronomy is about to get much much more exciting, with a whole new class of enormous telescopes developed on Earth and in space. How much more powerful? What will we be able to see?

Chad Weber - weber.chad@gmail.com Chloe Cain - Instagram: @chloegwen2001 I like to say that we’re in the golden age of astronomy, learning things about the Universe with a level of precision and resolution that previous generations of astronomers could only dream about. Imagine if you could show Galileo Galilei or Copernicus images from the Hubble Space Telescope, or the mighty Keck Observatory. They would blow their minds. But I really think the true golden age of astronomy is right around the corner. That’s because there’s a whole new class of observatories in the works right now which are going to take us right out to the edge of the Universe in ways that would have seemed impossible decades ago. In the land of telescopes, bigger is better, and the big telescopes are coming. Today we’re going to begin a two-part series of episodes all about the new supertelescopes under construction. In this first episode, I’ll talk about the enormous ground telescopes in development, and then next episode, I’ll talk about the space-based telescopes in the works. I’d like to thank Universe Today columnist Evan Gough for writing our original series on the upcoming supertelescopes. This video is based heavily on Evan’s work, so… thanks Evan! Let’s get started.

What is the Omicron Variant? On this episode, Neil deGrasse Tyson and comic co-host Chuck Nice discuss the emergence of the new Omicron Variant of COVID-19 with biomedical scientist and president of Regeneron, George Yancopoulos. How do we create antibodies for infectious diseases? We explore ebola, the Will Smith movie I Am Legend, and special rats with human immune systems! Find out how the immune system makes antibodies and how people can become resistant to a disease. What is “viral load”? What’s the difference between making vaccines and making antibody treatment? We take a deep dive into the science at the front lines of the pandemic. We break down how vaccines work and what monoclonal antibodies are. What’s the difference between mutations of Covid and mutations of the flu? Will we be getting a Covid shot every year? How do we help immunocompromised people who can’t get vaccinated? What does immunocompromised actually mean for their immune system? How does a virus mutate anyway? What goes behind the naming of the new variants? We take some hard-hitting patron questions like: How is Regeneron working to treat cytokine storms that seem to cause clotting in youth populations? What even is a cytokine? Learn about how our immune systems work to save us, but also how they can put us in danger, too. How do you get medical info out onto the front lines? Should we be worried about every mutation? Would too many false alarms make people ignore a real threat? How do you prevent panic? Is there a glimmer of hope in this new variant? We discuss how it is possible that a new variant could outcompete a current strain and make an overall less deadly version of Covid. Wouldn’t that be nice? All that, plus, Chuck offers some new pandemic-themed video game ideas to pass the time with.

And yet it’s also the most successful, in terms of sheer predictive power. Simply by following the math of quantum mechanics, incredible discoveries have been made. Its wild success tells us that the mathematical description provided by quantum mechanics reflects deep truths about reality. And by far the most successful, most predictive formulation of quantum mechanics is quantum field theory. It is our best description we have of the fundamental workings of reality. And the first part of quantum field theory that was derived – quantum electrodynamics – is the most precise, most accurate of all.
