We Are Not Alone

The universe just got a whole lot smaller, or larger depending on how you look at it.

According to National Geographic,

scientists at the University of Toronto have captured infrared images of a so-called normal star and its potential orbiter using a ground-based telescope at the Gemini Observatory in Hawaii.

We are living in historic times folks.

The King of the Night Sky

Jupiter

Jupiter

Tonite, right after sunset, look directly south, about 1/3 of the way up from the horizon. That bright star you’ll see is Jupiter, the King of Planets.

For the next few weeks, Jupiter is dominating the night sky. It’s currently in the constellation Sagittarius, coincidentally one of the most deep-sky rich constellations visible in the Northern Hemisphere.

In 1609, Galileo first viewed Jupiter through a telescope and saw right away the four Galilean Moons: Io, Calisto, Ganymede and Europa.

Over the course of several nights, the moons can be viewed orbiting around Jupiter - it was this discovery by Galileo that led to the downfall of the geocentric world view - that everything revolved around the Earth. This was the birth of the modern world-view, in short - the birth of modernity.

With binoculars, you can clearly make out Jupiter as a disk and see the moons. With a small telescope you can see the Jovian system. In my telescope I can see at least two equitorial bands and on a very clear night I can make out even greater details on the surface of Jupiter.

The Summer Triangle

From a picture shot from my backyard, the Summer Triangle.

From Vega, in Lyra, at the top, down to Deneb in Cygnus and then right to Altair in Aquila, the Summer Triangle is unmistakable in the Summer sky. Just look east, a bit after sunset. Vega should be near the zenith; the three stars are often the first to be visible in the night sky.

The MIlky Way flows right through the Triangle. If you have a nice dark night with clear skies, you should be able to see faint dust clouds and star fields.

With binoculars, you can scan the triangle and pick out most of its treasures.
