Latest Telescope Stories
Every so often, readers submit questions to our "Ask the Astronomer" series, wondering various things about the universe, space travel, or complex physics concepts we have no freaking answer for. Thankfully, when this happens, we have a few resident astronomers always willing to jump in and help us out--like professor of astronomy at Vanderbilt University, Dr. David Weintraub.
Typically, glitter is something that you expect to find in a grade-school classroom, but the small, flat reflective particles are serving as the inspiration for a new type of reflective mirror that could help NASA develop a low-cost new type of space telescope mirrors.
Astronomers at the University of California, San Diego have broken out a new tool in the search for intelligent extraterrestrial life: an instrument that can scan the sky for pulses of infrared light that may be indicative of messages from advanced civilizations on other worlds.
The South Pole Telescope is now ready for use in the search for black holes and will be joining its buddy, The Event Horizon Telescope.
A new instrument being developed at the University of Colorado Boulder could be capable of capturing images up to 1,000 times sharper than those provided by the Hubble Space Telescope, officials at the university have revealed.
RedOrbit sits down with Pat McCarthy, director of the Giant Magellan Telescope Organization, to discuss stargazing on the shortest day of the year (in the Northern Hemisphere).
Extremely detailed images produced using radio telescopes spread throughout Europe and the US have allowed researchers to pinpoint the exact locations in a stellar explosion where gamma rays are emitted.
Spotting Earth-threatening asteroids is tough partly because the sky is so big. But insects offer an answer, since they figured out long ago how to look in many directions at once.
Newly-Developed Camera Will Help Astronomers Peer Into Deepest Reaches of the Universe PALO ALTO, Calif., April 9, 2014 /PRNewswire/ -- Lockheed Martin [NYSE:LMT] and the University
When all 64 MeerKAT antennas are operational, the instrument radio telescope will be sensitive enough to pick up a cell phone signal from Saturn. NEWTON, N.C., March 27, 2014 /PRNewswire/ --
A telescope, designed to aid the observation of remote objects, collects some form of electromagnetic radiation (such as visible light). The Netherlands developed the first known practical telescope in the 17th century. The term "telescope" was termed in order to describe Galileo's instruments in 1611. However, Galileo was not the inventor of the telescope. It was Hans Lippershey, Zacharias Janssen, and Jacob Metius who are credited with the creation of the telescope. In 1668, Isaac Newton...
Telescope -- A telescope is an instrument composed of one or more lenses or mirrors to gather and focus electromagnetic radiation. Telescopes increase the observed angular size of objects, as well as their apparent brightness. The largest telescopes are used in astronomy. A telescope was first turned on the sky by Galileo Galilei, the Italian scientist. (Telescopes used for non-astronomical purposes may be called "transits," "monoculars," "binoculars," "camera lenses," or "spyglasses".)...
Radio Astronomy -- Radio astronomy is the study of celestial phenomena through measurement of the characteristics of radio waves emitted by physical processes occurring in space. Radio waves are much longer than light waves. In order to receive good signals, radio astronomy requires large antennas. Radio astronomy is a relatively new field of astronomical research. The earliest investigations into extraterrestrial sources of radio waves were by Karl Guthe Jansky, an engineer with Bell...
Parabolic Mirror -- A parabolic reflector or parabolic dish is a reflective device formed in the shape of a paraboloid of revolution. Parabolic reflectors can either collect or distribute energy such as light, sound, or radio waves. The parabolic reflector functions due to the geometric properties of the paraboloid shape: if the angle of incidence to the inner surface of the collector equals the angle of reflection, then any incoming ray that is parallel to the axis of the dish will be...
Amateur Astronomy -- Amateur astronomy, also called backyard astronomy, is a hobby whose participants enjoy watching the night sky (and the day sky too, for sunspots, eclipses, etc.), and the plethora of objects found in it, mainly with portable telescopes and binoculars. Even though scientific research is not their main goal, many amateur astronomers make a contribution to astronomy by monitoring variable stars, tracking asteroids and discovering transient objects, such as comets. Such...
