Eye to the Sky-Two more supermoons will brighten summer nights

If you missed the supermoon on July 12, you’ll get second and third chances to see one on Aug. 10 and Sept. 9.

Eye to the Sky-Stars serve as Earth’s timekeeper

All objects in the sky appear to rise in the east and set in the west. The stars are not really moving; it is the rotation of the Earth from west to east that causes this apparent clockwise motion. The speed of this rotation is so constant that it can be used to keep time.

Eye to the Sky-Clear summer nights offer stories in constellations

As summer approaches, the nights will be getting clearer and we will have better chances to view the stars. This is a good time to learn some of the stellar constellations.

Eye to the Sky-Mimicking the sun, stars also rise and set

The distances between the Earth and the stars are so great that the positions of the stars, relative to each other, will not significantly change in your lifetime.

Eye to the Sky-If you think winter's long, try it on Mars

The Earth has four seasons—spring, summer, fall, and winter. Do other planets in the solar system have seasons? Before answering that question, let’s review what causes the Earth’s seasons.

Eye to the Sky-Sun’s forces render comet ISON to dust and rubble

The “comet of the century” died before its time.

Eye to the Sky-, Eye to the Sky-Ancient traveler could be comet of the decade

In August I introduced you to comet ISON. In the last two months we have learned much more about the comet.

Eye to the Sky-Column: Voyager 1 reaches interstellar space

About every 175 years the orbits of the outer planets — Jupiter, Saturn, Uranus and Neptune — are arranged so that a spacecraft on a particular flight path can swing from one planet to the next without the need for large onboard propulsion systems.

Eye to the Sky-‘Comet of the century (maybe)’ coming soon

During the formation of our solar system — in the outer regions where it is cold enough to permit ices of water, methane, ammonia and carbon dioxide to exist — the comets were born.

Eye to the Sky-Perseid meteor showers to rain down in August

Every year in mid-August the Earth intersects the orbit of the Swift-Tuttle comet. Lewis Swift and Horace Tuttle independently discovered this comet in 1862.

Eye to the Sky-Today's telescopes superior to earlier models

There are many objects in the sky you can see with your unaided eyes, but these are only a small fraction of the objects you can see if you use a telescope.

Eye to the Sky-Saturn remains a stargazer’s delight for June nights

Saturn during April and May was the closest, biggest and brightest it will be during 2013. And it will still be a great view in June.
