RT from Astronomy Picture of the Day https://pump.jpope.org/apod: Random image from the archives APOD: 2000 September 3 - Henrietta Leavitt Calibrates the Stars http://apod.nasa.gov/apod/ap000903.html APOD Image http://apod.nasa.gov/apod/image/0009/leavitt_aavso.jpg Humanity's understanding of the relative brightness and variability of stars was revolutionized by the work of Henrietta Swan Leavitt (1868-1921). Working at Harvard College Observatory, Leavitt precisely calibrated the photographic magnitudes of 47 stars to which all other stars could be compared. Leavitt discovered and cataloged over 1500 variable stars in the nearby Magellanic Clouds. From this catalog, Leavitt discovered that brighter Cepheid variable stars take longer to vary, a fact used today to calibrate the distance scale of our universe. http://apod.nasa.gov/apod/ap000903.html #astronomy #picture #space #NASA #APOD

@steve interesting - but a pity that several links from that article are forbiden (403) or not found (404)
-
@mk I tested all four links. Only the first one had a problem (no space between URL and colon, so GS adds colon to URL).
-
@lnxw48 no, I' not referring to the links in the post, but in the page the post links to! There are 10 links, I tried 4, and got 2 403s and one 404 from them :(
-
@lnxw48, Please direct all comments and complaints directly to APOD. :-)
-
@steve No complaints. #APOD provides daily images with captions to help us lay people understand the universe around us. I'm okay with someone occasionally not knowing that a path on another server is inaccessible outside the academic fortress. @mk
-
@lnxw48 while that could explain the 403's it doesn't excuse the linkrot of 404s
-
@mk I was merely indicating I cannot fix links on the APOD site... but APOD can. :-)
-
@steve but of course - I wasn't suggesting you could
