Reveal the X-ray Universe, Make a Liveable Planet, and Catch Star-Blown Bubbles
Because the Chandra and XMM-Newton X-ray observatories observe twenty years in house this yr, S&T Information Editor Monica Younger celebrates the sphere of X-ray astronomy in our cowl story. Since astronomers discovered to rise above our ambiance with the approaching of the Area Age, X-rays have opened a brand new window on the universe. In the meantime, satellites have performed simply as massive a job in discovering worlds round stars close to and much. However what number of of those — particularly these round unstable however frequent M dwarfs — are liveable? Whereas August’s Perseid meteor bathe will compete with a 95%-lit Moon, the bathe is long-lived, so head out as early as late July to see it. In the meantime, the sky holds a lot different treasures, from deep-sky wonders which you can behold even by means of small telescopes to planets in morning and night skies, and even three asteroids which might be nearing opposition and visual by means of binoculars. For these with greater scopes, this is a problem: spot supernovae earlier than they occur in Wolf-Rayet stars, large stars already shedding their outer layers. On this challenge, you will additionally discover guides to the night and morning skies, explorations of lunar craters, and an S&T Check Report on Nikon’s mirrorless Z6 digicam.
