An international team of astronomers used the Hubble Space Telescope to help make a precise measurement of the mass of a planet outside our solar system. The Hubble results show that the planet is 1.89 to 2.4 times as massive as Jupiter, our solar system’s largest orbiting body. Previous estimates, about which there are some uncertainties, place the planet’s mass at a much wider range: between 1.9 and 100 times that of Jupiter’s. The planet, called Gliese 876b, orbits the star Gliese 876. It is only the second planet outside our solar system for which astronomers have determined a precise mass.

METHANE

Scientists at Paris Diderot University, France, and the National University of Cordoba, Argentina, have now developed an inexpensive catalytic system that reduces carbon dioxide to methane at ambient pressure and temperature. To mimic sunlight, the researchers used a solar simulator equipped with filters.

Methane is used primarily as fuel to make heat and light. It is also used to manufacture organic chemicals.


TERBIUM

Terbium is used to alter the original electrical or optical properties in materials that are used in solid-state devices, and as a crystal stabiliser of fuel cells which operate at elevated temperatures, together with ZrO2Terbium is also used in alloys and in the production of electronic devices.


HELIUM

Helium is also used as a coolant in Hydrogen fuelled rockets. During operation of a satellite in space, cryogenic properties of Helium help in avoiding overheating of its components. Being an inert gas it does not react with the other chemicals present and can be safely used.
