redOrbit Staff & Wire Reports - Your Universe Online A team of researchers from the University of Arizona’s Department of Astronomy have managed to use an Earth-based telescope to capture images of a world outside of our solar system, according to research scheduled to be published in an upcoming edition of The Astrophysical Journal. The telescope used essentially the same type of imaging sensor found in a standard digital camera instead of an infrared detector, and while the...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online The holy grail of planetary astronomy is the search for a potentially habitable planet, or even better, one that is shown to already contain life. There are various parameters that are needed in order to ascertain the habitability of worlds, such as whether liquid water can be sustained on its surface. Recent studies, however, have found that identifying some of these characteristics is rather difficult, and we may in fact...

Lee Rannals for redOrbit.com - Your Universe Online A team of astronomers from the UK and Chile have discovered three new planets classified as Super Earths. The planets are part of a group of eight new planets discovered orbiting nearby red dwarf stars. This study shows that virtually all red dwarfs have planets orbiting around them. Astronomers used the High Accuracy Radial Velocity Planet Searcher (HARPS) and Ultraviolet and Visual Echelle Spectrograph (UVES) telescopes for the...

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online The last two decades have brought unprecedented understanding of worlds outside of our solar system. The launch of the Kepler space telescope and other instruments have allowed astronomers to find and characterize hundreds of new planets, with thousands more candidates waiting to be confirmed. As our technology continues to improve, we will be able to isolate smaller and smaller planets, eventually identifying Earth-sized...

Image Caption: Artistic concept of a planetary system. Credit: Wikipedia/NASA/JPL-Caltech The term Astronomy encompasses a broad range of topics, including the study of stars, galaxies, and planets. In order to focus on the different areas of study, many subfields of astronomy emerge. One such area is the study of planets known, appropriately, as Planetary Astronomy. Observational Planetary Astronomy Even within the field of Planetary Astronomy, there are several divisions to...

Terrestrial Planet Finder -- The Terrestrial Planet Finder is a proposed NASA telescope system capable of detecting extrasolar terrestrial planets. In May 2002, NASA chose two TPF mission architecture concepts for further study and technology development. Each would use a different means to achieve the same goal - to block the light from a parent star in order to see its much smaller, dimmer planets. That technology challenge has been likened to finding a firefly near the beam of...

Extrasolar Planet -- An extrasolar planet is a planet orbiting around a star other than the Sun. Extrasolar planets were first discovered in the 1990s as a result of improved telescope technology, CCD and computer-based image processing which allowed far more accurate measurements of stellar motions. The first extrasolar planets were reported by the astronomer Aleksander Wolszczan in 1993, orbiting the pulsar PSR 1257+12. Subsequent investigation has determined that they are only planets...

  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
