Astronomers have new evidence that a vast reservoir of hot, diffuse gas about 400 million light years from Earth could contain the “missing matter” of the universe. The discovery was made with NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton. This missing matter, which the scientists stress is different from dark matter, is composed of baryonic […]
Astonishingly, climatologists can’t account for roughly half of the heat that is believed to have built up on the Earth in recent years. “The heat will come back to haunt us sooner or later,” lament National Center for Atmospheric Research (NCAR) scientists in an article in the journal Science. The scientists believe that satellite sensors, […]
Ice cores drilled from the Himalayas lack the distinctive radioactive traces that atomic explosions produce, possibly indicating that no new ice has accumulated since the 1950s, attendees at the annual meeting of the American Geophysical Union were told recently. The missing radioactivity, originating as fallout from atmospheric nuclear tests during the 1950s and 1960s, routinely […]
