A Mighty Wind Blew Away Gas and Made Early Galaxies Brighter
来源: Universe Today ·
When astronomers looked at photos of the early universe taken by the James Webb Space Telescope, they found something odd: an overabundance of bright galaxies about 400 to 500 million years after the Big Bang. But these galaxies should have been far less common so soon after the Big Bang. Researchers may have figured this out: Powerful ultraviolet (Lyman-alpha) radiation produced by dense clusters of young stars acted like a leaf blower, driving light-blocking gas and dust out of the galaxy and thereby making the galaxies appear brighter.

IEEE Program Schools Preuniversity Educators On Tech Topics
Now in their third year, the IEEE TryEngineering educator sessions continue to empower preuniversity teachers with specialized professional development programs on engineering topics and classroom-tested lessons. This year’s sessions, held across the United States, have focused on educating teachers about artificial intelligence and semiconductor technology. One session was held in Egypt. In all, 54 educators learned about the engineering design process this year. They received an overview of TryEngineering resources including the Making of a Microchip and Train Your Tree lesson plans. Worksho
How Do You Land on a Moon With Almost No Gravity?
Last August, looking up from the edge of an ancient river delta on Mars, the Perseverance rover ’s electronic eye spied an oblong shadow crossing the distant, glowing Sun. Phobos , the Martian moon named for the Greek god of fear and panic, was transiting the solar disk. Too small to darken the pale, dust-tinged sky, but orbiting close enough to eclipse a significant fraction of the Sun, Phobos passed in less than a minute. NASA’s Perseverance rover captured Phobos passing in front of the Sun from the surface of Mars. ASU/MSSS/SSI/JPL-Caltech/NASA The tiny moon, with its murky origins, is an e
