Wow! The Rosetta spacecraft is now seeing jets from Comet 67P/Churyumov-Gerasimenko, as the comet draws in closer to the sun.

As Comet 67P/Churyumov-Gerasimenko gets closer to the sun, it’s becoming more active. The European Space Agency’s Rosetta spacecraft – which has been flying in tandem with the comet since August 6 – captured the images to make the above montage on September 26, 2014, when Rosetta was 16 miles (26 kilometers) from the comet. The montage shows jets of dust and gas escaping from the neck of 67P/C-G.
.
Rosetta spent 10 years on a deep-space chase of this comet, which will reach its perihelion, closest point to the sun, in July 2015.
This November, the Rosetta spacecraft will send a probe down to land on the surface of this active comet!

October 4, 1957. On this date, the Soviet Union launched Sputnik I, the first artificial satellite to orbit the Earth. According to many space historians, the Space Age began on this date.
It was a polished metal sphere, made of aluminum alloy. It was 58 centimeters (23 inches) in diameter – about the size of a beach ball – and weighed just 184 pounds. Its four external radio antennae were meant to broadcast radio pulses. And broadcast they did. For 21 days in 1957, people around the globe heard Sputnik’s unassuming beep beep on the radio.

The pressurized sphere had five primary science objectives: test a process for placing an artificial “moon” into Earth orbit; provide information on the density of Earth’s atmosphere, calculated from Sputnik’s lifetime in orbit; test radio and optical methods of orbital tracking; determine the effects of radio wave propagation though Earth’s atmosphere; and check principles of pressurization that could be used on Earth-orbiting satellites. Clearly, the next step was to place living things in space.
Sputnik’s beeping was a symbol not only of Soviet Russia’s remarkable accomplishment, but also of what many immediately assumed was Russia’s superiority in space. The American public feared that the Soviets’ ability to launch satellites also translated into the capability to launch ballistic missiles that could carry nuclear weapons from Europe to the U.S.

Then the Soviets struck again. On November 3, 1957, they launched Sputnik II, this time carrying a much heavier payload, including a dog named Laika.
Sputnik I and Sputnik II sent shockwaves around the world. American political leadership scrambled to catch up. Ultimately, that extra push resulted in the United States sending the first astronauts to walk on the moon, on July 20, 1969.
Bottom line: On October 4, 1957, the Soviet Union launched the Sputnik 1 satellite into Earth orbit, and the Space Age began.

Barring cloudy days (along with both sunsets and sunrises), the sky will usually appear to be blue. This happens because of the way certain things can manipulate light. Just as prisms can bend light to create a rainbow and a mirror can reflect light back to where it came from, some objects can scatter light. The white light from the Sun hits oxygen and nitrogen molecules that make up most of the Earth’s atmosphere and is scattered to produce all the colors. However, since the color blue has a shorter wavelength than the rest,it is scattered more.
This effect also explains the other colors that can appear in the sky. Closer to the horizon, the sky will look much paler. Here, the light has traveled through more air and has been scattered more intensively, mixing in with the other colors and losing its blue tinge. With the Sun lower in the sky, as with sunsets, the light has to travel through even more light. This scatters the blue light further, allowing the red and yellow light to travel through.

Beautiful sunset in northern Montana’s Glacier National Park by Sashikanth Chintia Photography.

Sashikanth Chintia contributed this photo of a sunset at Glacier National Park, in the U.S. state of Montana on the Canadian border. He wrote:
We wanted to go to Grinnell Lake and shoot a time-lapse. Weather was not co-operative. After hiking 2 1/2 miles, we got rained out and we had to return back. When we hiked back we were offered with a beautiful sunset.
By the way, Glacier National Park encompasses over 1 million acres (4,000 square kilometers) and includes parts of two mountain ranges. The park contains a dozen large lakes, 700 smaller ones and 200 waterfalls. And glaciers? In 1850, the area now comprising the national park had 150 glaciers. There are 25 active glaciers remaining in the park today.
