Radiant Venus!

If you have noticed a bright object in the western sky after sunset over the past couple of months, that’s our beautiful “Sister Planet” Venus. It’s the third brightest object in the sky after the Sun and the Moon. And this month it is extra luminous, as it climbs up higher some 46 degrees east of our Daytime Star (at its “greatest eastern elongation” in astronomical terms).

Super Moons & Blue Moons

There appears to be quite a bit of fascination by the general public with the types of Moons mentioned in our title. So it seems appropriate to examine what “super” and “blue” actually mean in describing our lovely “Queen of the Night.” And it’s not quite what is implied in either of these cases!

Minor Meteor Showers

We have often featured the major annual displays of “shooting stars” in these columns, such as the Perseids of August and the Geminids of December. But there are several minor displays throughout the year that are also worth watching. This month’s Quadrantid Meteor Shower is one example. And we will also touch on the most famous of all “minor” showers as well.

“Wandering Stars”

Early skywatchers saw five bright objects slowly moving among the fixed stars.  These five were Mercury, Venus, Mars, Jupiter, and Saturn.  They called them “planets” from the Greek for “wandering stars.”  And to see this wandering for yourself, we focus on three of them this month in the early evening sky. About 45 minutes after …

Mercury Transits The Sun!

A wonderful daytime celestial spectacle will occur on the morning of November 11th. when the planet Mercury will cross the face of the Sun—an event that can be seen with properly filtered binoculars and small telescopes (and possibly without them by keen-eyed observers as well).   Transits of Mercury are infrequent events, so this month’s show …

SkyTalk October | Fall Astronomy Day

This biannual event happens on Saturday, October 5th, this year. That date has special significance this time around since it occurs just one day after the historic date of the beginning of the Space Age on October 4th, 1957, with the launching of Sputnik.  So there’s sure to be more fun and excitement than usual. …

SkyTalk September | So Far Yet To Go

Two basic astronomy questions were recently asked in a survey taken of the graduating class of a prestigious New England university.  One was: “What causes the seasons?”  The other: “What causes the phases of the Moon?” Astonishingly, 86% did not know the answer to either one! Although introductory astronomy courses are offered at most colleges …

SkyTalk August | Thrilling Moons & Glorious Rings!

The two most exciting of all the planets (Venus and Mars not withstanding!) are perfectly placed in the evening sky for your enjoyment this month. They are the many-mooned planet Jupiter and ringed planet Saturn—both offering wonders not to be missed by skywatchers.

SkyTalk July | Moon Day!

This month contains the date that many (including myself) consider to be the most important and significant in all of human history.  It’s July 20th, 1969—when Apollo 11 landed on the Moon in the Sea of Tranquility and we traveled to another world for the first time 50 years ago! If it’s clear on Saturday …

SkyTalk June | It’s Jupiter By Jove!

After a long drought of planets in the evening, mighty Jupiter is finally up for viewing this month.  It offers plenty to see with both binoculars and telescopes of all sizes, and is a welcomed sight to skywatchers.  All five major planets were visible in the evening sky last summer (a true planetary bonanza!), but …
