EarthSky Tonight—Tonight Nov 10, Can we see stars outside our Milky Way galaxy?

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org One of you wrote, “Are there any stars outside our own galaxy that we can see with just the eye?” The answer is no – unless you count seeing the combined light of many billions of stars. From the northern hemisphere, the only galaxy outside our Milky Way that is easily visible to the eye is the great galaxy in the constellation Andromeda – also known as M31. It is shown in the image at the top of this post. In late ... Full Story

Dave, the image at right shows the view of the Andromeda galaxy through a telescope. We hope you are not looking through the eyepiece of your telescope when sweeping through the sky for this galaxy. That would be hard. You need a wider field of view to spot the ... Full Story

EarthSky Tonight—Nov 8, Young moon easier to spot after sunset on November 8

Yesterday, the moon shone closer to the setting sun, so the moon followed the sunbeneath the horizon shortly after sundown. Tonight’s moon will be higher in the sky and will stay out longer after sunset. From our mid-northern latitudes, the lunar crescent sits low in the southwest sky at dusk and nightfall. Keep in ...

EarthSky Tonight—Nov 6, A famous variable star in the constellation Cepheus

Courtesy of EarthSky A Clear Voice for Science www.EarthSky.org Delta Cephei is a famous variable star in the constellation Cepheus. With clock-like precision, this rather faint star doubles in brightness every 5.36 days. You can see the brightness change best if you contrast this star to others nearby. The constellation Cepheus requires a dark sky to be seen, but if you can spot this constellation, you might be able to find the variable star. You will find it high in your northern sky on ...
