![]() Houston TX (SPX) Dec 03, 2009 Using more advanced analytical instruments now available, a Johnson Space Center research team has reexamined the 1996 finding that a meteorite contains strong evidence that life may have existed on ancient Mars. The new research focused on investigating alternate proposals for the creation of materials thought to be signs of ancient life found in the meteorite. The new study argues that ... read more |

Blushing Dusty Nebula![]() A recent NASA/ESA Hubble Space Telescope image of part of NGC 7023, or the Iris Nebula, highlights a perfect dust laboratory in the sky. On Earth, we tend to find dust nothing more than a nuisance that blankets our furniture and causes us to sneeze. Cosmic dust can also be a hindrance to astronomers because cameras using visible light cannot see through it. However, studying cosmic dust in ... more Astronomy Question Of The Week: Is There A Photograph Of The Universe ![]() If the question means "Has anyone stepped outside of the universe with a camera and taken a picture of it?" then the answer is, of course, no. The concept of 'universe' means the totality of all things, including space and time. So logically, there can be no 'outside' to the universe. (Although speculative cosmological theories propose other concepts.) One - very abstract - representation ... more Rocket Test Will Carry Purdue Experiment ![]() Purdue University researchers are designing and building an experiment that will operate during a test flight of a new type of reusable rocket to be launched by aerospace company Blue Origin. The experiment will be used to study how fluids behave in low gravity, providing information that could help engineers design better components for a variety of technologies used both on the Earth and ... more |

Fermi Telescope Peers Deep Into Microquasar![]() NASA's Fermi Gamma-ray Space Telescope has made the first unambiguous detection of high-energy gamma-rays from an enigmatic binary system known as Cygnus X-3. The system pairs a hot, massive star with a compact object - either a neutron star or a black hole - that blasts twin radio-emitting jets of matter into space at more than half the speed of light. Astronomers call these systems ... more Two Successful Rockets With Experiments In Weightlessness ![]() During the last week two sounding rockets with microgravity experiments were successfully launched from Esrange Space Center, the operational space facility of the Swedish Space Corporation (SSC). The Brazilian motor VSB-30 was used during both flights. The TEXUS project is a sounding rocket program with the primary aim to investigate the properties and behaviour of materials, chemicals ... more Lunar Water Probably Came From Comets ![]() In a discovery that may solve the mystery behind the source of moon's water, an evidence from NASA's LCROSS mission suggested that much of it was delivered by comets that slammed into the Earth's satellite billions of years ago. Previous missions had also found hints of lunar water but its source was never clear. One idea is that it forms when hydrogen atoms from the solar wind latch onto ... more |
