London, March 26 : Astronomers, for the first time, have observed a rare asteroid as it was hurtling towards our planet and have captured the only spectrum of it before it exploded in our atmosphere, which may lead to an advanced warning system for Earth.
The observation was made by UK astronomers, using the Science and Technology Facilities Council's (STFC) William Herschel Telescope on La Palma.
Washington - The space shuttle Discovery undocked Wednesday from the International Space Station to head back to Earth after a week on a milestone construction mission that has doubled the capacity of the orbiting laboratory.
The mission astronauts installed a fourth set of solar panels, completing the power plant needed to double the station's electrical generating capacity. The power allows the station to sustain six long-term residents instead of the current crew of three, and more occupants could arrive as early as May.

The mission astronauts installed the fourth and final set of solar panels needed to double power capacity at the station so it can hold six instead of the current three long-term residents - possibly as early as May. The crew completed three spacewalks, including one to install the panels.
Washington, Mar 25 : A team of Australian researchers has found a way to predict plagues of disease-carrying mosquitoes up to two months ahead.
According to ecologist Associate Professor Corey Bradshaw from the University of Adelaide, this should help fight outbreaks of mosquito-borne disease like dengue and Ross River fever by allowing efficient and cost-effective mosquito control.
Washington, March 25 : Researchers studying a hydrogen-producing, single-celled green alga, Chlamydomonas reinhardtii, have unmasked a previously unknown fermentation pathway that may open up possibilities for increasing hydrogen production.
C. reinhartii, a common inhabitant of soils, naturally produces small quantities of hydrogen when deprived of oxygen. Like yeast and other microbes, under anaerobic conditions this alga generates its energy from fermentation.
Washington, March 25 (ANI): Researchers at the Georgia Institute of Technology have developed a surface treatment that boosts the light absorption of silicon photovoltaic cells in two complementary ways.
The surface treatment increases absorption both by trapping light in three-dimensional structures and by making the surfaces self-cleaning - allowing rain or dew to wash away the dust and dirt that can accumulate on photovoltaic arrays.
