- Jan 13, 2003The Terrestrial Planet Finder (TPF) mission will have the technology to look for signs of life in the light reflected or emitted by planets orbiting nearby stars. But nobody knows exactly what signals life would emit. Clues from studies of Earth's early atmosphere are guiding
- Jan 8, 2003Discover the remarkable new planet that has a year that lasts a terrestrial day, and rains down not water, but iron. The discovery is made possible by a planetary detection method--called a transit search--where the parent star dims as the orbitting planets pass across
- Dec 2, 2002Esperamos que alienígenas sejam muito mais espertos que nós. Não só eles possuirão a sabedoria de eras, mas viajarão a uma velocidade de empenamento, terão a habilidade de transformar (ou destruir) planetas inteiros e sua civilização se espalhará pelas galáxias.
- Oct 16, 2002The rapid advances in genetic sequencing have allowed comparisons previously unavailable to those scientists who try to understand how such a complicated structure as DNA might have evolved. But communicating an entire organism compactly in code may require a more ancient art: the music
- Oct 9, 2002A research team claims it has found carbonates in dust around two dying stars, where water cannot exist. If the finding is confirmed, astronomers may have to re-think some assumptions about the presence of water during the formation of our own solar system. But both
- Oct 2, 2002Phoning home intergalactically may have one natural prerequisite if a civilization is hoping to connect: timing their precursor signal or 'ring' so that we might know that they're broadcasting. Dr. Robin Corbet, of the Universities' Space Research Association discusses his research findings on Synchronized SETI.
