Read article: Hubble back in business
Eskimo Nebula is 5000 light years from Earth and resembles a face inside a furry parka when viewed from ground-based telescopes. Hubble resolved the ‘hood’ into a disk of material containi...
In 1967 Davis, then at the Brookhaven National Lab, built the first experiment to detect neutrinos produced by the Sun. Neutrinos only interact weakly with matter and are extremely difficult to detect...
The waveguide structure was created by pouring a mixture of copolymer solution and molecular laser dye into a mould situated on top of a silicon wafer. The solution was allowed to solidify over 12 hou...
Quantum particles such as electrons can be in a superposition of two or more quantum states. This means that an electron can, for instance, be in two places at the same time. However, classical object...
Hamilton came to her conclusions after studying the writings of female scientists over the past two and a half thousand years, and reading descriptions of women scientists by others. She analysed the ...
A collision with a Near-Earth asteroid is believed to have wiped out the dinosaurs 65 million years ago. Near-Earth asteroids are usually piles of rock from the Mars-Jupiter asteroid belt whose orbit ...
Black holes are usually detected by the effects of their vast gravitational field on the orbits of nearby astronomical objects such as stars. Naked black holes have no such material near them making i...
Since the US stopped testing in 1992 it has relied on the “stockpile Stewardship” programme to maintain the reliability and safety of its nuclear weapons. But a number of misconceptions we...
Adaptive-optic telescopes differ from normal telescopes by using a thin flexible primary mirror that can easily be deformed. A bright guide star near the observing area acts as a “beacon” ...
NAUTILUS was designed to observe the gravitational waves produced by collisions between objects such as black holes or neutron stars. According to the Frascati’s group calculations, signals from...
