Twenty-four unusual stars, 18 of them newly discovered, have been observed in new Hubble telescope images. The stars are white dwarfs, a common type of dead star, but they are odd because they are made of helium rather than the usual carbon and oxygen. This is the first extensive sequence of helium-core white dwarfs to be observed in a globular cluster, a dense swarm of some of the oldest stars in our galaxy. A study, accepted for publication in the Astrophysical Journal, suggests that these...

Tests conducted on Planck at Europe's Spaceport in Kourou, French Guiana, have confirmed that the satellite's subsystems work perfectly, and the helium dilution cooler tanks have now been filled. While the final clean-up continues, the solar array has been checked, the satellite has been integrated with its launcher adapter and fuelling is complete. The last of the system reference tests, of the telemetry and telecommand subsystem, was completed on 17 March. The tests, carried out over the...

Over the past few weeks, the upper part of Planck's outer solar array has been covered with multi-layer insulation, the satellite has been prepared for upcoming helium filling operations, several sub-system functional tests have been carried out and it has undergone final cleaning before launch. Multiple layers of insulation On Wednesday 4 March, multi-layer insulation (MLI) was fitted on the upper part of the outer solar array at the base of the service module. Both the insulation and the...

The U.S. space agency says the James Webb Space Telescope's first mirror segment has successfully completed its first series of cryogenic temperature tests. The tests were conducted in the X-ray and Cryogenic Facility at the National Aeronautics and Space Administration's Marshall Space Flight Center in Huntsville, Ala. The (tests) performed here are crucial to the success of the program since they'll ensure the mirrors and components will be able to withstand the extreme cold temperatures of...

Models of how Saturn and Jupiter formed may soon take on a different look. By determining the properties of hydrogen-helium mixtures at the millions of atmospheres of pressure present in the interior of Saturn and Jupiter, physicists at Lawrence Livermore National Laboratory and the University of Illinois at Urbana-Champaign have determined the temperature at a given pressure when helium becomes insoluble in dense metallic hydrogen. The results are directly relevant to models of the interior...

GREENBELT, Md., Dec. 15 /PRNewswire-USNewswire/ -- Solar flares are the most powerful explosions in the solar system. Packing a punch equal to a hundred million hydrogen bombs, they obliterate everything in their immediate vicinity. Not a single atom should remain intact.   At least that's how it's supposed to work.   "We've detected a stream of perfectly intact hydrogen atoms shooting out of an X-class solar flare," says Richard Mewaldt of the California Institute of...

Jupiter has a rocky core that is more than twice as large as previously thought, according to computer calculations by a University of California, Berkeley, geophysicist who simulated conditions inside the planet on the scale of individual hydrogen and helium atoms. The results were published Nov. 20 in Astrophysical Journal Letters. The simulation predict the properties of hydrogen-helium mixtures at the extreme pressures and temperatures that occur in Jupiter's interior, which cannot yet be...

Solar Radiation -- Solar radiation is radiant energy emitted by the sun due to nuclear fusion reactions. Fusion is the process whereby stars produce huge quantities of energy from the fusion of hydrogen or helium, in one of the most efficient processes of energy generation. The radiation referred to is usually electromagnetic energy, particularly infrared radiation, visible light, and ultraviolet. Some stars are known to emit radiation of other wavelengths. Solar neutrinos are a...

  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
