The best places to see the northern lights are Alaska and northern Canada, Norway, Sweden, and Finland. During periods of particularly active solar flares, the lights can be seen in Scotland and northern England.
Winter is usually the best time to see the northern lights, due to lower levels of light pollution. September, October, March, and April are some of the best months to view the aurora borealis. Agencies such as NASA and the National Oceanic and Atmospheric Administration issue aurora alerts when the displays are expected to be very impressive.

Until now, NASA's Helios 2 was the vessel that has got the closest to the sun: in 1976, it came within 27 million miles of the surface of the sun.
This is about to change, as NASA is pl...
When planning to send its brand new vessel to investigate on the sun, NASA has to take into account serious threats to its astronauts.
The biggest obvious threat is the extremely hot area that surrounds the sun, or what we call the virus. The research will actually focus also on finding out why the temperatures in the area are so high.
When traveling to the sun, astronauts take huge risks, as the sun emits an enormous amount of radiation. Usually this radiation is associated with heart issues or strokes.
Therefore, the closer you find yourself to the sun, the more chances you have to die sooner than you would normally had it not been for the journey.
Dark Matter is a bizarre, unknown ingredient of the universe, which scientists cannot observe directly, but takes up 80 percent of the mass of the universe.
It is not seen by the naked eye ...
The way massive objects of the universe bend and distort gravity and light indicates to scientists about the existence of dark matter. The way large objects move about in the universe (velocity) also is a factor pushing towards the probability of much more mass than is visible.
Dark matter provides the gravity and weight in galaxies, which would fall apart if all they had was what is visible to scientists via their various instruments.
