  • Tiny Chance of Planet Collision

    Astronomers calculate there is tiny chance that Mars or Venus could collide with Earth though it would not happen for at least a billion years. The finding comes from simulations to show how orbits of planets might evolve billions of years into the future.

  • Swine flu strikes India

    At last swine flu also struck India. Initially the cases of infection were largely imported from North America. But eventually the transmission of the virus was taking place even among those who were never in direct contact with people returning from abroad.

  • Secrets of dark energy to be unveiled

    Way back in 1920s, the American astronomer Edwin Hubble discovered that the universe is expanding, with galaxies moving away from each other at velocities proportional to their mutual distances. At that time astronomers also believed that the rate of expansion will slow down in future.

  • Oxygen produced from Moon rock

    Moon is devoid of oxygen. Any astronaut who has to travel to moon would have to carry a lot of oxygen and this a very costly affair. Perhaps costing as much as US$100 million per tonne according to some estimates. Now, scientists are examining potentially cheaper ways to produce oxygen on the Moon itself.

  • Microbes can clean wastewater

    It is very costly to purify and desalinate dirty water. Two methods are traditionally used to desalinate water. One process is called reverse osmosis and another process is called electrodialysis which uses electricity to draw salt ions out of water through a membrane.

  • Methane on Mars

    A recent finding has raised interesting possibilities about the presence of life on Mars. The US space agency NASA has reported the discovery of huge release of methane gas into red planet’s atmosphere.

  • Lunar eclipse may provide clue to the presence of life

    Now astrobiologists are excited about the lunar eclipse. It is because the light that is reflected back from the moon during the eclipse carries clues indicating the presence of light on a planet. This was revealed during a lunar eclipse on August 16, 2008.
