Deep-Ultraviolet Quantum Interference Metrology with Ultrashort Laser Pulses Stefan Witte,* Roel Th. Zinkstok,* Wim Ubachs, Wim Hogervorst, Kjeld S. E. Eikema[dagger] Precision spectroscopy at ultraviolet and shorter wavelengths has been hindered by the poor access of narrow-band lasers to that spectral region. We demonstrate high-accuracy quantum interference metrology on atomic transitions with the use of an amplified train of phase-controlled pulses from a femtosecond frequency comb laser. The peak power of these pulses allows for efficient harmonic upconversion, paving the way for extension of frequency comb metrology in atoms and ions to the extreme ultraviolet and soft x-ray spectral regions. A proof-of-principle experiment was performed on a deep-ultraviolet (2 x 212.55 nanometers) two-photon transition in krypton; relative to measurement with single nanosecond laser pulses, the accuracy of the absolute transition frequency and isotope shifts was improved by more than an order of magnitude.

Folks... this is still inside information from Judy Fältskog at NASA and it has not gone public yet due to the magnitude of the findings!
__________________________________________
Judy runs BOINC@HOME and SETI@HOME and other such applications. I'm afraid that is the limit of her association with NASA. In her web pages, she
a) calls herself a "quantum physicist", which is a qualification I never heard of in my professional life in science
b) posts texts and pictures related to Wiccan rituals
...and frankly, all of the above reeks of New Age. It is impossible to have a career with NASA and not have publications in refereed journals. It is quite possible, however, to present yourself as one while pursuing a keen interest in alien abductions and magic crystals.

@Vicky... Come on Vicky no need to get snotty about it... Judy is who she is and we dont need to prove anything until it is official. They are obviously using more than radio telescopes in the full analysis! This is all unofficial for now and we will need to wait until it is processed.
Other things apart from radio telescopes are being used in the full analysis..
I hope so much for this to be true... but saying that, who posts such sensitive could-be-life-changing news on their.... wait for it.... facebook profile ? ( wouldn't that be censored of something ? )
Mm...

If this turns out to be a hoax, which it looks like it will, I'm going to be angry. There are people in this world truly dedicated to finding signs of extraterrestrial life which in my estimation is an endeavor more worthy of praise then 90% of what everyone else does on this miserable little planet. All a hoax does is demean their work and politically set them back decades.

Soon you will all scientifically realize that their are beings all over this planet in orbit, in atmosphere and on the surface. In all light spectrum's and densities.

I don't think so, that one's targeted for IR, not UV. At any rate, you'll note they don't call it a radio telescope, because it isn't.
