Mercury's iron core generates a magnetic field about one percent as strong as Earth's. The field is quite active, frequently interacting with the solar wind and funneling plasma from the sun to the planet's surface. The hydrogen and helium captured from the solar wind help create part of M...

"Sometimes cinnabar is found with droplets of native mercury, in its pure form on the surface and should not be handled because native mercury is easily absorbed by the body and is toxic," Ottaway says. Also, cinnabar shouldn't be cut or ground without water to prevent the inhalation of ...
General relativity and changes in Mercury's orbit The orbit ofMercuryis shifting very gradually over time due to the curvature of space-time around the massive sun,according to NASA. As the closest planet to the sun, Mercury’s perihelion (the point along its orbit that it’s closest to th...
Tannoy Mercury M2 (1997) The Mercury M2 made an immediate impression when they burst onto the scene in the late 1990s. Back then, we said they were the closest anyone had come to creating the perfect mass-market standmounter, and we stick by that assertion as we look back at the M2 wi...
forest firesandlightningstrikes also add to the man-made pollution. SO2 and NOx become acids when they enter the atmosphere and react with water vapor. The resulting sulfuric and nitric acids can fall as wet or dry depositions. Wet deposition is precipitation: acid rain, snow, sleet or fog....
of the chatter is about the national security supplemental that may or may not include funding for Ukraine, Israel and the U.S. border, rather than the FY2024 appropriations bills. The Senate will begin a two-week recess next week. The House will be in recess the second of those two ...
One torr (symbol: Torr) is approximately equivalent to one millimeter of mercury in a manometer at 0 °C. In the vacuum industry, the term "micron" is also used; it is derived from the unit torr, where one milliTorr equals one micron. The unit torr is named after the Italian physicist...
The Redstone rocket was brought to Warren in honor of Shepard, one of the original Mercury Seven astronauts. YouTube The connection to the Jeff Bezos Blue Origin craft? The Bezos spaceship was named New Shepard, after Alan Shepard. Pretty cool!
aAs long ago as 1610 Galileo had observed that Jupiter has four very large moons,one of which is nearly the size of the planet Mercury . (Scientists later determined that the giant planet has more than six moons,)But what lay beneath those colorful clouds? Was there a solid surface? Or ...
