... HI in Abell 370, a galaxy cluster at z=0.37 With increasing redshift, galaxy clusters and their surroundings show a higher fraction of optically blue galaxies (the Butcher-Oemler effect). This effect is noticeable from z 0.1 and is a strong effect by z = 0.4. We are using the coadding HI technique ...

... temperature of about 15,000,000°F. As the heat travels out through the Sun’s layers, it becomes much cooler, but still hot enough to glow in visible light. For comparison, the temperature of a wood fire is less than a 1,000°F. MYTH 3: All stars are exactly the same. FACT: All stars are not the same. ...
