A visit to Ecuador’s astronomical center
Can isolated black holes account for dark matter? Rick PinsonLong Beach, California Astronomers estimate about 100 million black holes wander the Milky Way. Since black holes emit no light, we rely on indirect methods to infer their presence. The first method is to search for a black hole’s gravitational influence on nearby objects, such asContinue reading "Ask Astro: Could isolated black holes...

Binocular Universe: Double duty
When a massive star dies, it goes out with a bang, creating a stunningly bright explosion that can temporarily change the look of the night sky. The brightest and closest may be visible with the naked eye, but even those in distant galaxies can be easily spotted with amateur equipment from your backyard. And now,Continue reading "Bright, young supernova now visible in M101"

For many of us, light pollution has robbed our skies of once readily visible objects. That’s why many residential observers have turned away from nebulae and galaxies to pursue other targets, such as double stars. This month, let’s enjoy a few of my favorite springtime binocular binaries. We begin with a challenging binocular target, IotaContinue reading "Binocular Universe: Double duty"
