James Webb Space Telescope; reionization; comet
Astrophysics and Astronomy | Physics
On the eve of its long-anticipated launch, we explore one of the many areas of exploration of the JWST, the early universe after the birth of the first stars and the reionization of the interstellar medium. We also take a look at a large comet showing activity beyond the orbit of Uranus, historical trivia, space news updates, and more. Join us for a walkabout the galaxy.
More than just a handy way to clean up that dirty floor, vacuum paradoxically provides an abundance of opportunities, from pumps to cleaners to chambers. While vacuum doesn’t make the world go round, it does prevent it from spiraling into the sun in a life-ending cataclysm. And beneath that modest exterior lies a churning froth of background energy pervading the universe at a whopping nanojoule per cubic meter. So whether you need an unimpeded path for your infrared laser or a quick cleanup of those spilled crumbs, get vacuum! Vacuum: Nature's Way to Beautiful (The Body Shop).
