How will future alien scientists know whether life existed in our solar system? One method may be to sift through the planetary debris left when our sun becomes a white dwarf. Astronomers are doing just…
The Curiosity rover has landed on Mars, driven around, started its scientific mission and, as of 4am today (AEDT), started reporting integrated science results. In a news conference at the American Geophysical…
In an announcement today, NASA poured cold water on rumours that its Curiosity rover had found life on Mars. Curiosity found evidence that it had landed on an ancient riverbed, and it identified some interesting…
