Good morning! If you would still like to walk in the trees tomorrow, remember to take bus 60 at 1:00 after school.
(CNN)Potentially life-giving water still flows across the ancient surface of Mars from time to time, NASA scientists said Monday in revealing a potential breakthrough in both the search for life beyond Earth and human hopes to one day travel there.
While the discovery doesn’t by itself offer evidence of life on Mars, either past or present, it does boost hopes of that the harsh landscape still offers some refuge to life. Read more.
Zones depleted of oxygen do exist in nature and have previously been discovered along populated coastal areas off the eastern and southern coasts of the United States and the Baltic Sea. But this is the first time such a place has been observed in the open ocean.
HeliWhale said that the patented new control system of coaxial rotors also provides the helicopter with high velocity of up to 250 kilometers per hour at max speed.
The aircraft, weighing 270 kilograms, is capable of carrying a payload of another 180 kilograms, the company said.
Afalina can also be refueled with conventional 95 octane car fuel, with the consumption between 12 and 16 liters (3 to 4 gallons) per hour
A rare combination of celestial events will grace the night sky later this month. NASA says a supermoon lunar eclipse will take place September 27.
The stunning show will be visible to the naked eye, and will start next Sunday, September 27, between 5pm and 6pm PDT time (between midnight and 1am GMT on Monday).
The super moon, or a perigee full moon, means that the moon will seem 14 percent bigger, 30 percent brighter and fuller than usual. It happens because the moon will be at its closest point in its orbit around the Earth.
The human eyeball is kind of incredible, being able to see millions and millions of colors, automatically adjust to light conditions, and, in camera terms, it contains about 50 f-stops of capability. Light enters our eyes and falls on photoreceptive proteins in our retina (the rods and the cones). From there, information is sent to the brain via the ganglion and bipolar cells behind the rods and cones. Your brain adjusts the changing information from your eyes — like when you’re using color filters (tinted sunglasses) — almost imperceptibly.
