A Christmas comet is on the way to our skies. Comet Catalina (C/2013 US 10), which has been slowly brightening in the southern-hemisphere skies all year, has crossed the celestial equator moving north. It will finally become visible to northern-hemisphere observers in the pre-dawn sky from this week through late January, and will remain visible to southern-hemisphere observers until late December. Grab your binoculars and get ready to see this end-of-year visitor from the most distant reaches of the solar system [Read more…] about Comet Catalina Arrives in the Dawn Sky

The Halloween Fireballs

October 27, 2015 by Brian Ventrudo Filed Under: Solar System

Taurids — Taurid fireball imaged on October 28, 2005 by Hiroyuki Iida.

The Taurid meteor shower runs from early October through late November each year and peaks in the early morning of November 12. This year, in 2015, that’s just a day after new Moon, which means the sky will be at its darkest for this event. Because they are active over Halloween, and they displayed an impressive outburst about 10 years ago at the end of October, the Taurids are sometimes called the Halloween Fireballs [Read more…] about The Halloween Fireballs

Orionid Meteor Shower 2015

October 14, 2015 by Brian Ventrudo Filed Under: Solar System

The usually reliable Orionid meteor shower runs from October 17-25, 2015, and peaks in the early morning of October 21. The first-quarter Moon will set after midnight at the peak of the shower year, so it will be a great year to see the Orionids, which at their peak, can display as many as 30 meteors per hour [Read more…] about Orionid Meteor Shower 2015

Mercury, the Moon, and Assorted Stars and Planets Before Dawn

October 9, 2015 by Brian Ventrudo Filed Under: Solar System

Mercury, a waning crescent Moon, and assorted other stars and bright planets as seen 30 minutes before sunrise in the eastern sky.

If you’re up for a weekend challenge, grab your binoculars, find a clear view down to the eastern horizon, and head out about 30 minutes before sunrise to spot fingernail-thin crescent Moon right next to the planet Mercury in the pre-dawn sky. A pair of binoculars will help you pull an image of the pair out of the brightening sky. Westward (above) this pair you will also see the planets Mars, Jupiter, and Venus in the constellation Leo. The event favors observers in the northern hemisphere, but it is also visible in the south, although the sky will be slightly brighter when Mercury emerges above the horizon.
