Deep space objects guide Earths GPS system Nov 4, 2009
The VLBI is a special network of radio telescopes from all over the world that together have the resolving power of a telescope thousands of miles in diameter. (Though quasars burn intensely brightly, their enormous distance makes them too faint to locate accurately with a conventional optical telescope. (MSNBC -- Technology)

How to Choose a Telescope Sep 30, 2009
A scope's aperture determines both its light-gathering ability (how bright the image appears) and its resolving power (how sharp the image appears). What does this mean. (SkyAndTelescope.com)
Unveiling the true face of a gigantic star Aug 8, 2009
8 metre telescopes as an interferometer, giving the astronomers the resolving power of a virtual, gigantic 48 metre telescope ... The resolving power achieved with AMBER is so great that one can recognize a 1-Euro coin placed on the Brandenburg Gate in Berlin from Bonn. (EurekAlert!)
Scope Calculator Jul 29, 2009
Theoretical Resolving Power: The angular size of the smallest detail you can see at high magnification. This tells you the closest double star you can expect to separate. (SkyAndTelescope.com)
End of an era in photography Jul 7, 2009
"The world became a different place when the resolving power of digital cameras equaled or surpassed film," he said. "This was not a tragedy. This was a train wreck that we saw coming for 15 years. And by this point it wasn't even a train wreck, it was a fender bender.". (San Francisco Chronicle -- Technology)
Gamma rays burst from M87's black hole Jul 7, 2009
"We had scheduled gamma-ray observations of M87 in a close cooperative effort with the three major gamma-ray observatories VERITAS, HESS and MAGIC, and we were lucky that an extraordinary gamma-ray flare happened just when the source was observed with the VLBA and its impressive spatial resolving power," adds Matthias Beilicke of Washington University. A very high energy gamma ray flare was accompanied by a radio flare from the black hole vicinity. (Astronomy Now Online)
Super-energetic Bursts Near Giant Black Hole Jul 3, 2009
In 2007 and 2008, the astronomers using these gamma-ray telescopes combined forces with a team using the National Science Foundation's continent-wide Very Long Baseline Array (VLBA), a radio telescope with extremely high resolving power, or ability to see fine detail ... The VLBA offered a millionfold improvement in resolving power, allowing the scientists to determine that the gamma rays are coming from the immediate vicinity of the black hole ... The VLBA offers resolving power equal to the... (Science Daily)
Planck and Herschel:Lifting the Veil on Inflation and Starbirth May 17, 2009
However, resolving power decreases with increasing wavelength, so in the far infrared a wide mirror is crucial for seeing with even moderate sharpness. Herschel and Planck will take separate two-month journeys toward L2, the second Sun-Earth Lagrangian point, some 1. (SkyAndTelescope.com)
First Two ALMA Antennas Successfully Linked May 14, 2009
Such pairs of antennas are the basic building blocks of imaging systems that enable radio telescopes to deliver pictures that approach or even exceed the resolving power of visible light telescopes. Each antenna is combined electronically with every other antenna to form a multitude of antenna pairs. (Science Daily)
May-June 2009 GSA Bulletin media highlights Apr 29, 2009
Sadler et al. demonstrate how computer algorithms can build a clock with at least ten times more resolving power by searching for order among all of the published information concerning more than 3,800 appearance and extinction events of graptolites collected from over 400 locations worldwide. Their method, which can be applied to other fossil groups and time intervals, incorporates radio-isotopically dated volcanic ash layers to calibrate the deep-time clock and quantify its uncertainties.

Nanoparticles Harnessed To Track Cancer-cell Changes Apr 20, 2009
Meanwhile, another group outside Stanford, now collaborating with the Nolan group, has developed a prototype device that can detect Raman signals in a continuous flow of single cells, analogous to flow cytometry but with higher resolving power, Shachaf said. The study was funded by the National Cancer Institute's Center for Cancer Nanotechnology Excellence Focused on Therapy Response and by the Flight Attendant Medical Research Institute. (Science Daily)
Sharpest image of Orion's binary star captured Apr 3, 2009
"This corresponds to the resolving power of a space telescope with a mirror diameter of 130 meters," he added. The AMBER new image "clearly separates the two young, massive stars of this system," said a press release from the Max-Planck-Institute for Radio Astronomy. (Xinhuanet, China)
Can Hubble Space Telescope See Flag... Mar 15, 2009
Even the largest ground based telescope would not be able to resolve such small details because the blurring effect of Earth's atmosphere limits the resolving power of large ground based telescopes long before the theoretical best performance of the telescope. The Hubble Space Telescope is however above Earth's atmosphere, so it can achieve its maximum theoretical. (Suite101.com)
This Week's Sky at a Glance Mar 15, 2009
Of course, this also reduces your eye's aperture and theoretical resolving power, so experiment with different-sized holes. Send me your results. (SkyAndTelescope.com)

The Compact Array provides high resolving power (more detail) than signals from a large single dish. The Australia Telescope was originally suggested in 1974-75 as an interferometer based at Parkes to extend the existing Parkes Radio Telescope s power. (Suite101.com)
'Mona Lisa' exposed Feb 8, 2009
Five years ago, Cotte gained permission from officials at the Louvre Museum to image the "Mona Lisa" using a custom-built camera with serious resolving power. The data collected by one scan would take more than 10 500-gigabyte computer disk drives to store. (OregonLive, OR -- Business)
9 institutions officially sign agreement for 25-meter Giant Magellan Telescope Feb 7, 2009
Scheduled for completion around 2019, the GMT will have the resolving power of a single 24. 5-meter (80-foot) primary mirror. (EurekAlert! -- Business News)
