内容正文:
If you could put on a special pair of glasses and look up into the night sky, you would see something amazing, a sky full of exoplanets, planets orbiting stars beyond our own solar system. A team of superhero space telescopes, in a sense, has done just that. Using powerful technology, they've peared into space, discovering thousands of these distant planets and unveiling their secrets. The first exoplanet discoveries were very down to earth. They were made from the ground, pioneering new techniques around base telescopes began capturing evidence of giant scorchingly hot planets around other stars. But to see exoplanets more clearly, including small, rocky words like our own telescopes needed a boost to began launching them into space, lifting them above earth's atmosphere. This superhero team of space telescopes, hubble, chAndra spitzer, kepler and test, were free from all the noise and interference from earth's atmosphere. Gittern air molecules scattering light, clouds and moisture, and the curtain parted on a galaxy crowded with exoplanets, giant ones, tiny ones, rocky and gaseous, deep frozen and superheated planets with two or three sons, super s mini neptunes and worlds that were just plain weird, like nothing we had ever seen before. And now a new marvel of technology joints, nas team, the James web space telescope, its infrared vision can peer into the atmosphere of exoplanets, expanding what we know about distant worlds. High on the list of odd EXO planets to observe is a terrifying place where might rain glass sideways. This exoplanet is called HD one eight nine 733b and it's a hot jupiter,a giant gaseous world that hugs its star in such a tight orbit that its temperatures is more than one thousand seven hundred degrees farn height. It's wins hole at more than five thousand four hundred miles per hour. Hd one eight nine seven three three b has been a favorite target of our space telescopes. Spits are measured, its temperature and winds. Hubble discovered that the planets clouds are deep blue due to the raining glass or silicates, and chAndra observed its star and x rays watching the planet shadow is at past in front of the star, a much larger shadow than previously thought, because huge amounts of the planet's atmosphere are evaporating into space. NASA next great observation, tory, the James web space telescope will also turn its supervision on hd one eight nine seven three three b like pizer, IT sees a powerful infrared, but webs vision will penetrate far more deeply into this planet's atmosphere and others than ever before. What will I find? Put IT all together. And its a super team, extraordinary telescopes, exceptional vision and mind, expanding exoplanets discoveries.

$Last week, the road was fixed, the broken sign was slowly mixed. The work was done. IT was done. Time just show is when things belong the last firm. What the thing went through, not wine, not when. Tomorrow, lunch will be prepared, the change will be arranged and share, we said the lights will shine, will. Future tenses work with this no matter. Keeps this single time.
