Metrologists looking for new kilogram standard

Metrologists, those concerned with the measurement of things, met at the Royal Society in London this week to redefine kilogram as the mass of platinum used as the standard kilogram reportedly shed some of its weight.

A solid cylinder of platinum-iridium alloy, called the International Prototype Kilogram, has been kept in a safe at the headquarters of the International Bureau of Weights & Measures (BIPM) in Sevres, near Paris.

The International Prototype Kilogram is the last metric unit still defined using a physical object.

British scientists to launch Android smartphone satellite into space

A group of scientists from the Surrey Satellite Technology Ltd. and Guildford-based Surrey Space Centre has plans to launch an Android-powered smartphone satellite into the space.

It is the first time that a smartphone is going to serve as the brain of an orbital satellite, dubbed the STRaND-1 (Surrey Training, Research and Nanosatellite Demonstrator)

Researchers discover T. Rex dinosaur’s predecessor

A group of paleontologists has discovered a new dinosaur species, dubbed Eodromaeus, at the foothills of America's Andes.

The long-necked Eodromaeus was a fast-running carnivore. It was around 5 feet in length, and had a very long tail and was 15 to 17 pounds in weight.

Eodromaeus is the most primal dinosaur found so far among the theropods. It roamed South America around 230 million years ago, only a few million years after dinosaurs first evolved.

NASA tests Discovery’s fuel tank

The National Aeronautics & Space Administration (NASA) on Friday filled space shuttle Discovery's external fuel tank with millions of gallons of super-cold propellants to determine what had caused cracks in the fuel tank during last month's launch attempt.

The three-hour tanking test, as it was called, was started at 7 a. m. EST (1200 GMT). Sensors installed on the tank continue to gather data as the tank was emptied in the afternoon. Sensors kept on recording the tank's performance through Saturday when it warms to ambient temperature.

Total lunar eclipse to take place on late Monday night

People throughout North and Central America will be able to experience a total lunar eclipse between late Monday night and early Tuesday morning.

Depending on weather conditions, observers will be able to see moon entering the Earth's inner shadow, which is also called umbra, at 10:33 p. m. The red-brown shadow will eventually cover the whole of the moon, making the sky darker and stars more visible.

The total eclipse will last for 72 minutes, from 11:41 p. m. PST on Monday to 12:53 a. m. on Tuesday. After that the moon will start emerging from umbra.

NASA discovers two mysterious bubbles at the centre of galaxy

NASA researchers have discovered two massive and mysterious bubbles that could be the remnant of an eruption from a gigantic black hole at the centre of our galaxy.

One theory is that the bubbles could have formed from a massive burst of star formation that could have occurred in the centre of the Milky Way, creating a massive cloud of energy and gas.

But, other theory states that the super-sized massive black hole at the centre of the galaxy gulped down something big, and then released an energy burp that resulted in the emergence of the bubbles.
