Alcohol Consumption and Hypertension. Several mechanisms have been proposed for the relationship between alcohol and elevated BP. An immediate effect of alcohol ingestion is vasodilation in some vascular beds. Sustained intake accompanied by high blood alcohol levels, however, results in short-term elevation of BP.
Uranus is a pale blue in this natural color image because its visible atmosphere contains methane gas and few aerosols or clouds. Blue Orb on the Horizon. 1  A recent NASA Hubble Space Telescope view reveals Uranus surrounded by its four major rings and by 10 of its 17 known satellites.his false-color view of the rings of Uranus was made from images taken by Voyager 2 on Jan. 21, 1986, from a distance of 4.17 million kilometers (2.59 million miles).
Because of this, its poles are sometimes pointed almost directly at the Sun. Uranus' atmosphere is made up of hydrogen, helium, and methane. The temperature in the upper atmosphere is very cold. The cold methane gas is what gives Uranus its blue-green color. The rapid rotation of Uranus causes winds up to 600 kilometers per hour to blow in its atmosphere. Uranus has eleven known rings which contain dark, boulder-sized particles. Uranus has 27 named moons.
