The NASA/ESA Hubble Space Telescope has released the largest ever image of the Andromeda galaxy, opening up 100 million stars and star clusters to public exploration. Itâs also the sharpest view of Andromeda, the closest galaxy thatâs a spiral like our own Milky Way, ever taken.
Dizziness or light-headedness when standing up occurs as a result of abnormal blood pressure regulation. Normally, when people stand, gravity causes blood to pool in the veins of the legs and trunk. This pooling lowers the blood pressure and the amount of blood the heart pumps to the brain. Low blood flow to the brain causes the dizziness and other symptoms.
Whenever I stand up I have a minute where I'm really dizzy and I have to stop and stand still for it to leave. I can't see properly and my head feels light. This is usually on a hot day, though I always drink lots of water, I always have a drink bottle. C.
