Spectacular VLT Photos Unveil Mysterious Nebulae

Quite a few of the most beautiful objects in the Universe are still shrouded in mystery. Even though most of the nebulae of gas and dust in our vicinity are now rather well understood, there are some which continue to puzzle astronomers.

This is the case of a small number of unusual nebulae that appear to be the subject of strong heating – in astronomical terminology, they present an amazingly “high degree of excitation”. This

The desire for healthy-looking skin has existed throughout the centuries and has often led humanity to flowers and other plants in search of assistance. COSMACTIVE treads the same path, but uses the latest in biotechnology to identify and extract the active ingredients from a wide range of plants.

Under the umbrella of the EUREKA project COSMACTIVE, the French research company Greentech has developed a new way of identifying and selecting active ingredients that gives it, and its Spanish par

Two billion years ago, in a far-away galaxy, a giant star exploded, releasing almost unbelievable amounts of energy as it collapsed to a black hole. The light from that explosion finally reached Earth at 6:37 a.m. EST on March 29, igniting a frenzy of activity among astronomers worldwide. This phenomenon has been called a hypernova, playing on the name of the supernova events that mark the violent end of massive stars.

With two telescopes separated by about 110 degrees longitude, the Roboti

A team of Carnegie Mellon University and NASA scientists will travel to the Atacama Desert in northern Chile in April to conduct research that will help them develop and deploy a robot and instruments that may someday enable other robots to find life on Mars. The researchers will be using the Atacama, described as the most arid region on Earth, as a Martian analog.

The group is funded with a $3 million, three-year grant from NASA to the university’s Robotics Institute. They are collabo

Mobile DNA’s role in vancomycin resistance of Enterococcus faecalis

‘Jumping’ elements of DNA have enabled the bacterium Enterococcus faecalis to acquire stubborn resistance to a range of antibiotics – including a “drug of last resort” that is used against such bacterial pathogens.

That is one of the conclusions reached by scientists at The Institute for Genomic Research (TIGR), which sequenced and analyzed the complete genome of E. faecalis V583, a strain of the

Early on the morning of 30 June 1908, the vast forest of western Siberia was illuminated by a strange apparition: an alien object streaking across the cloudless sky. White hot from its headlong plunge into the Earth’s atmosphere, the intruder exploded about 8 km above the ground, flattening trees over an area of 2000 square kilometres.

Despite the huge detonation, equivalent to a 10 megaton nuclear warhead (about 500 times the energy of the Hiroshima atomic bomb), there were few if any casu
