Despite space observatories such as theHubble Space Telescope(HST) andJames Webb Space Telescope(JWST) being closer to the action, ground-based telescopes can achieve greater dimensions and are far less restricted by weight. When telescopes onEarthare built in a good location, with wide sky views...
But optics also tells us that the diameter of the mirror determines the resolving power of the telescope. Resolving power is the ability to separate two objects that apparently form a single object to the naked eye. In other words, a bigger diameter enables the Universe to be observed in ...
While Hubble has helped us chart the universe's expansion and peered deep into time, a bigger NASA telescope is on its way. Called the James Webb Space Telescope, it is expected to launch in 2018. The telescope will observe in infrared and have a 6.5-meter (21.3-foot) mirror, giving ev...
As the afterglow from this burst faded it was studied using both the GROND instrument on the MPG/ESO 2.2-metre telescope at La Silla and also with the X-shooter instrument on the Very Large Telescope (VLT) at Paranal. The clear signature of asupernova, later named SN 2011kl, was found...
In 2016, China's Five-hundred-meter Aperture Spherical radio Telescope—the largest single-aperture radio telescope in the world—gathered its first light. Since then, the telescope has undergone extensive testing and commissioning and officially went on
China's space telescope looking for gravitational wave breakthrough Since the detection of gravitational waves, scientists have been eager to find electromagnetic signals corresponding to the gravitational waves. Chinese wine group buys three vineyards in Chile China's wine company, Yantai Changyu Pioneer...
discovered recently, but the world’s largest radio telescope, the Square Kilometre Array (SKA), began construction in Australia and South Africa in December 2022 and will soon open its sensitive radio eye on the universe. This suggests that detecting and using the 21-cm forest may soon be ...
There are many similarities between the progress we've made in understanding the universe and in piecing together life's inner workings.Like the technological developments that took us from Galileo's telescope to the Hubble to the JWST,life science tools have also improved rapidly.From early light...
The 500-metre-wide radio telescope in rural China will let us study galaxies, pulsars and potential alien signals that would be too faint for any other scope
aHis greatest glory was that in 1609 he was the first person to turn the newly invented telescope on the heavens to prove that the planets revolve around the sun rather than around the earth. 他是转动最近被发明的望远镜的第一个人在天堂证明的1609年他的最巨大的荣耀那,行星围绕在太阳附近而不是...
