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 ...
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...
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...
This situation may be about to change, however. Not only have a number of high-redshift radio-loud quasars been 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 ope...
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
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...
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
Optical lenses are one such invention. The discovery of lenses in ancient times led to the development of eyeglasses, which helped people with vision problems see more clearly. Later, the invention of the microscope and telescope enabled scientists to see things that were previously invisible to ...
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 microscopes to modern super-resolution ones,these developments have afforded researchers a deep look into biology's infinitesimal (无限小...
