They used Cepheid variables out to 20 Mpc as the calibrating method for a host of secondary distance indicators such as Type Ia supernovae, surface brightness fluctuations, and the Tully Fisher method. ... Luminous red supergiants provide a new method of measuring the Hubble constant that is independent of the Cepheid distances. ... Larger spiral galaxies will yield larger numbers of red supergiants and hence a more accurate distance modulus. ...

... Polish scientists at the Space Research Centre, Polish Academy of Sciences, in Wroclaw, south-west Poland, have constructed an instrument called SphinX (short for Solar PHotometer In X-rays), which is an X-ray spectrophotometer, that will obtain spectra in the energy range 0.5--15 keV in 256 energy channels with frequency of up to 100 times a second. ...

This type of image is called a ``flat field'', because you want the field of view to look as flat as possible. In space there aren't any flat fields you can use, but we do have one right here: the Earth. ... It takes a lot of sophisticated computer processing to turn this into a real flat field for Hubble to use, but luckily there are a lot of smart people working on the problem. ...

... The history of star formation was successfully analyzed for the first time based on the spectra of the stellar population of dwarf galaxies of low surface brightness outside the Local Group. We have investigated the stellar population of two dwarf spheroidal galaxies KDG61 and KDG64 in the central part of a close group of galaxies M81. ... These galaxies are dominated by the old stellar population (12-14 billion years) of low metallicity ([Fe/H] ~ -1.5). ... KDG61 . ... KDG64 ...
