We’re in the lowest layer. Down here, elements like oxygen and nitrogen are balanced, breathable and hold electrons steadily in atomic orbit. This is what’s called the neutral gas atmosphere. As we rise through the layers, things change. It’s a fourth state of matter, known as a plasma. And the existence of these two atmosphere types means there’s a shift from one to the other. The boundary isn’t clear, but it’s definitely there....
The eclipse will reach Texas at approximately 1:10 p.m. ET and Maine by 2:22 p.m. ET, it will move beyond the eastern North American border. NASA’s rocket launches on Monday won’t necessarily have that same gravitas, but science works in increments. The launches will be streamed live, so it’s possible for you to see what happens. Why is NASA firing rockets during the eclipse? According to NASA, the ionosphere thins at night and thickens when the sun’s rays are hitting it....
Deep within the cosmos, a fading star’s quiet death was sharply interrupted. “It comes off as switching on and off.” Scaringi is lead author of astudy on the star published Mondayin the journal Nature Astronomy. Entering their final stages of life, they will become white dwarfs. The dying star is part of the two-star system dubbed TW Pictoris, located 1,400 light-years away.

NASA’sArtemis program isn’t just about getting humans back to the moon. It’s also about sending machines, including the water-hunting Viper lunar rover. It will map the area and look for water at the surface and below. NASA describes the lunar south pole as “one of the coldest areas in our solar system.” The Nobile region is home to plenty of shaded areas that are prime spots to look for ice....
The upcoming launch ofNASA’suncrewed Artemis I mission will do more than send the Orion capsule around the moon. It will also involve sending a collection of secondary missions off into space. In a statement last week,NASA describedspace radiation as being like a nanoscale demolition derby. BioSentinel will monitor the vital signs of yeast, which NASA says have similar biological mechanisms to human cells. There’s a mini biotech lab on board that will monitor the yeast cells....
Often forgotten, however, are the real-life astronomers who kind of already do it. Right now, they should be making more stars than ever. “But for some reason, they have shut down. They’re no longer forming new stars.” But hold on, you’re probably still on that bit about astronomers going back in time. If they can swing that, why didn’t they show up toStephen Hawking’s famous time-traveler-only dinner party? We need this term as a measurement because light doesn’t travel instantaneously....
The exoplanet WASP-121b, which resides about 900 light-years from Earth, is an egg-shaped scorcher. Temperatures on the planet’s day side can reach up to 4,600 degrees Fahrenheit. But the planet’s night side has, until now, remained in the dark (sorry). Telescopes at the South African Astronomical Observatory discovered WASP-121b in 2015. He notes its extremely hot day side is hotter than some stars. The answer: The night side gets down to about 2,200 degrees Fahrenheit....
