But even then, just resting a few million years in the Earth's magnetic field would produce no magnetization. ... Still, as Gilbert observed, in a long iron rod that magnetism was channeled to the ends, where it could be noted. ...

Magnetar . ... Credit Copyright: Robert Mallozzi ( UAH , MSFC ) Explanation: What do you call a neutron star with a super-strong magnetic field? ... Imagine a star with more mass than the sun, the density of a neutron, and a magnetic field about a thousand trillion (a one followed by 15 zeroes) times stronger than Earth's. It sounds exotic and theoretical , but strong evidence for the existence of magnetars has recently been announced based on data from orbiting X-ray and Gamma-ray observatories . ...

The circular polar orbits, which cover all the near-Earth space, are the most favorable for comprehensive studies of the radiation conditions near the Earth. ...

... Astronomers of the SAO together with an international group of scientists have proposed an explanation to the long-standing mystery of why magnetic fields are more common amongst cool white dwarf stars than amongst young and hotter ones. ... As the result magnetic white dwarfs demonstrate excess in their frequencies in the temperature range below 14000K. The authors also show that the strongly magnetic white dwarfs are of the oldest stars of the Galaxy originated from intermediate-mass relic stars. ...

... Polar Cap Potential . ... The solar wind propagation delay time calculation used here is conceptually similar to the T(IMF) calculation in Kelly, et al. ... The older continuous data are from key parameter data files. ... Note: Very high values of Solar Wind Speed, Solar Wind Pressure, IMF Magnitude and Bz, and Polar Cap Potential are likely indications that WIND has reentered the Earth's magnetosphere; such data is not indicative of solar wind conditions or impending severe geomagnetic disruption. ...

... 2000 June 8 . Active Regions, CMEs, and X-Class Flares . ... Explanation: Space Weather forcasters are predicting major storm conditions over the next few days as the active Sun has produced at least three strong flares and a large coronal mass ejection (CME) since Tuesday, June 6th . ... X-ray hot plasma suspended in looping magnetic fields arcs above this region, cataloged as AR9026. AR9026 appears as a large group of sunspots in visible light images. ... About APOD | ...

... Aromatic dust emission features and emission lines from molecular and atomic hydrogen are detected but they are not particularly strong. The dominant spectral features are emission lines from moderately ionized species of argon, neon, and sulfur, which are used to determine the physical conditions in the ionized gas. The ionized gas excitation shows strong variations on parsec scales, some of which can plausibly be associated with individual hot stars. ... ADS Citation Query . ...

... ARC 3.5m | Weather Closure Conditions . The enclosure will be closed by the Observing Specialist under the following conditions. ... This policy will be consulted whenever there are questions or disagreements concerning closure of the APO 3.5-meter telescope due to hazardous conditions or situations, at times when telescope operations are being overseen by an APO Observing Specialist. ... the on-duty Observing Specialist has full responsibility, and sole authority, to make this decision. ...

... The air just sit there and doesn't get stirred. ... Normally, the air is hottest near the ground and gets cooler as you go up. ... If it weren't for the temperature profile, convection wouldn't occur: Because the temperature decreases with altitude, cold air sits on top of hot air, allowing convection. ... The air above the ground is hot, the air above the water is cold. ... The land cools down faster than the sea, so the air above the ground is colder than the air above the water. ...

... part 1 | ... The Basic Stages in Earth's Pre-geological Development . ... After fragments of the Vortex sleeves separated, whirlwinds of second and third orders ("NC" - new micro-vortex) were generated- future planet cores and their satellites - all of them developing independently, governed by the common laws of development of cosmogenic vortexes. ... Our planet's core today is comprised of considerably deteriorated cosmogenic vortex; consequently, the Earth has a moderated magnetic field. ...

... A more direct measurement of magnetic field strength can be made using Faraday rotation (FR) and free­free absorption (FFA). ... Discussion We suggest several intrinsic and extrinsic mechanisms to depolarize the emission. ... Beam depolarization: If the magnetic field in a foreground Faraday screen is tangled on scales much smaller than the observing beam, regions with similar degrees of polarization but opposite signs will average out and the ob­ served degree of polarization will be decreased. ...

The annual Perseid meteor shower continues until 20th August, with the peak activity occurring during the night of 11/12th August. ... The comet is in a fairly stable orbit and it sheds a fresh dust trail every time it reaches perihelion (closest distance to the Sun). ... David Asher of the Armagh Observatory is a little more cautious stating that with no meteor storm data in relatively recent times predictions cannot be calibrated to the same accuracy as the Leonid meteors. ...
