Quasar pairs: a redshift puzzle?
Article Abstract:
Astrophysicist Halton Arp has published the results of years of analysis which he claims proves that quasars are ejected in pairs by nearby galaxies, and not located at the edge of the universe, as calculated by redshift. His finding, if true, would invalidate the basic astronomical distance measure.

'Hot Jupiters' leave theorists in the cold
Article Abstract:
Astronomers have discovered a new class of plants called 'hot Jupiters.' The orbits of these planets are 10 to 20 times closer to their stars than the Earth is to the sun. The orbital periods last only a few days. Current models cannot explain the formation of these planets so close to the stars.

Twinkle, twinkle, little quasar
Article Abstract:
Radio astronomers in Australia have discovered a quasar that flickers faster than any other quasar. The quasar, called PKS 0405-385, should have a temperature of about 10 to the 20th power degrees, but this is 100 million times hotter than theory allows.
