Scientists have identified a massive eruption from the sun in April that reached all the way to Earth and may be responsible for knocking out a satellite, creating a so-called "zombie satellite."

The huge explosion of plasma and magnetic energy, called as a coronal mass ejection (CME), occurred on April 3 and was observed by NASA's sun-watching STEREO spacecraft, according to the U.S. Naval Research Laboratory (NRL). The laboratory released new images of the solar storm last week.

JAKARTA, Indonesia - Scientists on a deep-sea expedition off Indonesia have discovered a towering volcano: It rises 10,000 feet (3,000 metres) from the ocean floor, yet remains far from sight at the water's surface.

U.S. and Indonesian researchers, using a powerful sonar system and a robotic vehicle with high-definition video, are exploring terrain off Sulawesi island in hopes of getting a glimpse into complex and little-known marine ecosystems.

They have mapped 2,400-sq.-miles (6,200 sq.-kilometres) of sea floor since setting off last month, an area equal to the size of the U.S. state of Delaware, according to a news release from the American embassy in Jakarta.

CAIRO - An Austrian archaeological team has used radar imaging to determine the extent of the ruins of the one time 3,500-year-old capital of Egypt's foreign occupiers, said the antiquities department Sunday.

Egypt was ruled for a century from 1664-1569 B.C. by the Hyksos, a warrior people from Asia, possibly Semitic in origin, whose summer capital was in the northern Delta area.
