You mean it was not the honorable cut of a sword that robbed Tycho of his nose, but the gangrenous effects of syphilis?

Say it wasn't so!!!

Tycho had a nose for astronomy indeed. His nose is still around, as you can see. I visited the island of Hven when a new Tycho museum had opened and saw what I'm sure is a true story of Tycho visiting a nose-othecary" to buy himself a suitable new nose. My, my, those hotheaded young noblemen settling the question of their honor in duels!

The picture of Tycho's nose was posted by Tycho's associate Johannes Kepler, who, on the other hand, has been accused of possibly murdering Tycho to get hold of his outstanding astronomical observations.

Other members of the Aries Project, mistaking Miles and Luna for doctors, expect them to clone the leader from this single remaining part. Miles steals the nose and "assassinates" it by dropping it in the path of a road roller.>>

"Nasal Ranger" Smelloscope Will Save Denver From Stinky Pot
Robert Sorokanich [The Telegraph, TheDenverChannel via VICE] 11/14/13

<<Colorado's newly legalized marijuana industry has had an unforeseen dark side: pungent dankness running wild on the noses of innocent citizens. Only a mechanical hero could save them. Call in the Nasal Ranger.

Yes, in order to better investigate odor complaints, Denver Police are using a bizarre-looking nose telescope that quantifies the stinkiness of stinky stinks. The Nasal Ranger Field Olfactometer, designed and manufactured by the family-owned, Minnesota-based business St. Croix Sensory, is actually a rather ingenious device. To function, a dial-operated mixer delivers varying ratios of filtered and full-flavor air to the operator's nose. Meek odors wash out when mixed with small amounts of purified air, while a particularly stinky smell can still remain detectable in a 500:1 mix.

This past summer, Gizmodo's Editor-in-Chief Geoff Manaugh and his wife, writer Nicola Twilley—of NYC cow tunnel fame—visited St. Croix Sensory to learn more about the Nasal Ranger first-hand. Or first-nose, as the case may be. There, the firm's co-founder and technical director, Charles McGinley, led them through the odoriferous process.

To facilitate its use and application, the ingenious smelloscope offers an ODOR TRACK'R GPS-powered app, storing data from every sniff check to create a stink-map. Perfect for keeping an eye (or a nose) on repeat olfactory offenders.

So far, the majority of Denver's doobie dankness complaints have stemmed from growers, not consumers. Wielding the Nasal Ranger, an officer can impose a fine of up to $2,000 for odors detectable beyond an 8:1 clean-to-stinky ratio. Obviously, this isn't new technology; the Nasal Ranger has been used for over a decade to monitor offensive or dangerous odor production in agriculture, industry and sanitation facilities. But legalizing marijuana opens up a whole unfamiliar realm for state governments, and this strange device could give police departments some quantitative sway in arguments between legal pot producers and their scent-sensitive neighbors.Denver Police expect a whole new wave of smell complaints when retail sale of marijuana becomes legal on January 1st, 2014. So you Denverites might want to fan your arms around if you see Johnny Law unholster that smelloscope.>>

  so why is it so hard to pin down the distance to Tycho's Supernova Remnant

Expansion Velocity of Ejecta in Tycho's Supernova Remnant Measured by Doppler Broadened X-ray Line Emission
Asami Hayato et al. (Submitted on 30 Sep 2010)

<<We show that the expansion of ejecta in Tycho's supernova remnant (SNR) is consistent with a spherically symmetric shell, based on Suzaku measurements of the Doppler broadened X-ray emission lines. All the strong K_alpha line emission show broader widths at the center than at the rim, while the centroid energies are constant across the remnant (except for Ca). This is the pattern expected for Doppler broadening due to expansion of the SNR ejecta in a spherical shell. To determine the expansion velocities of the ejecta, we applied a model for each emission line feature having two Gaussian components separately representing red- and blue-shifted gas, and inferred the Doppler velocity difference between these two components directly from the fitted centroid energy difference. Taking into account the effect of projecting a three-dimensional shell to the plane of the detector, we derived average spherical expansion velocities independently for the K_alpha emission of Si, S, Ar, and Fe, and K_beta of Si. We found that the expansion velocities of Si, S, and Ar ejecta of 4700+/-100 km/s are distinctly higher than that obtained from Fe K_alpha emission, 4000+/-300 km/s, which is consistent with segregation of the Fe in the inner ejecta. Combining the observed ejecta velocities with the ejecta proper-motion measurements by Chandra, we derived a distance to the Tycho's SNR of 4+/-1 kpc.>>

Tycho SN 1572: A Naked Ia Supernova Remnant without Associated Ambient Molecular Cloud
Wenwu Tian, Denis A. Leahy (Submitted on 27 Dec 2010)

<<The historical supernova remnant (SNR) Tycho SN 1572 originates from the explosion of a normal Type Ia supernova which is believed to have originated from a carbon-oxygen white dwarf in a binary system. We analyze the 21cm continuum, HI and 12CO-line data from the Canadian Galactic Plane Survey in the direction of SN 1572 and surrounding region. We construct HI absorption spectra to SN 1572 and three nearby compact sources. We conclude that SN 1572 has no molecular cloud interaction, which argues against previous claims that a molecular cloud is interacting with the SNR. This new result does not support a recent claim that dust, newly detected by AKARI, originates from such a SNR-cloud interaction. We suggest that the SNR has a kinematic distance of 2.5 - 3.0 kpc based on a nonlinear rotational curve model. Very-high-energy Gamma-ray emission from the remnant has been detected by the VERITAS telescope, so our result shows that its origin should not be an SNR-cloud interaction. Both radio and X-ray observations support that SN 1572 is an isolated Type Ia SNR.>>
