Look to the northeast near the constellation Lyra to watch the Lyrid meteor shower starting at about 11pm on Wednesday, April 22.

Look to the northeast near the constellation Lyra to watch the Lyrid meteor shower starting at about 11pm on Wednesday, April 22.

Just in time to celebrate Earth Day, the Lyrid meteor shower comes into full swing! Stay up late on the night of Wednesday, April 22 and witness shooting stars that will seem to come from the northeast sky.

The peak of this light show will be after 11 pm and really kick in after midnight as the moon sets and leave behind dark skies. Enjoy 15 – 20 meteors per hour in areas outside the light dome of the city until the morning hours of Thursday.

A Crescent, a Planet, a Cluster and a Star

Written by The Night Sky Guy on April 20, 2015 – 5:07 pm -

Look toward the western horizon about an hour after sunset to view four spectacular celestial objects Monday, April 20.

Look toward the western horizon about an hour after sunset to view four spectacular celestial objects Monday, April 20.

A crescent moon marks the corner of a giant quadrilateral which is also held down by bright-white Venus, orange Aldebaran and the Pleiades.

About and hour after sunset, on Monday, April 20, look on the western horizon as twilight ends. The slowly darkening sky will make the Seven Sisters difficult to spy, however, with binocular, you should be able to hunt down this 300 light year distant star cluster. Happy Hunting!

Sisters Meets Goddess

Written by The Night Sky Guy on April 10, 2015 – 10:20 pm -

Venus meets the Pleiades Cluster low in the horizon just after dusk on Saturday, April 11.

Venus meets the Pleiades Cluster low in the horizon just after dusk on Saturday, April 11.

As the sun settles in for the night, on Saturday, April 11 the brightest “star” in the sky is the planet Venus which appears low on the western horizon. Very close to Earth’s sister planet is the Pleiades star cluster (M45), a tight stellar grouping that can looks like a scattering of diamonds through binoculars.

The nearby setting sun will make it difficult to see this cluster, but this 300-light-year distant group of young stars will slowly come in view as the darkness covers the sky. One of the closest clusters our planet, the Seven Sisters will appear only 2.5 degrees to the right of 9.4-light-minute-distant Venus.

Sagittarius Nova Re-Awakens

Written by The Night Sky Guy on April 7, 2015 – 9:09 pm -

Backyard astronomers are reporting that an exploding star is quickly coming back to life and brightening again in the southern constellation of Sagittarius the Archer.

First spotted by Australian sky-watcher John Seach on Sunday, March 15, the exploding star shot up in brightness a couple of weeks ago, then faded back down to magnitude 6, just past the limit for viewing by the unaided eye from a dark location. But in the past week and half, new observations show that the star has brightened again to magnitude 4.5—making it just barely visible to the naked eye from city suburbs and an easy target from dark locations.

Watch Moon Turn Red

Written by The Night Sky Guy on April 3, 2015 – 9:59 pm -

A lunar disappearing act—the grand sky event of the week—occurs on the morning of Saturday, April 4, and will be visible from the western half of North America.
The moon will begin to enter Earth’s dark shadow at 3:16 a.m. PDT, when the first bite out of the moon’s disk becomes evident. The most dramatic part of the show, when the lunar disk takes on a dramatic orange-red hue, begins at 4:58 a.m. PDT, and this totality will last less than five minutes.

Catch a Nova

Written by The Night Sky Guy on March 17, 2015 – 1:34 pm -

Find the Teapot asterism in the constellation Sagittarius, peak under its lid to see an active nova.

Find the Teapot asterism in the constellation Sagittarius, peak under its lid to see an active nova.

This weekend a nova was identified in the Sagitarius constellation, thanks to the eagle eyes of John Seach of Australia.

Named the un-glamerous PNV J18365700-2855420, this star was never before seen until star-gazer Seach saw it brighten to magnitude 6.3. This site was verified by Japanese amateur astronomers and confirmed that it is intensifying now to 5.3 magnitude, making it barely visible to the naked eye from a dark location, but easily with binoculars. Scientists will not know how bright it will get, but keen observation over the next few days will tell a better story.

Novae are the violent explosions of the outer atmosphere of tiny white dwarf stars. These Earth-size, hot cores of long-dead sunlike stars have a companion star from which they gravitationally siphon off gases. Over time, this matter accumulates on the surface of the white dwarf. When the star reaches critical temperature, it ignites in a massive thermonuclear explosion that can be seen thousands of light-years away.

To view this intriguing event, skywatchers will need to rise early in the Northern Hemisphere and look low on the southeastern horizon. Look for the constellation Sagittarius, which contains an asterism called the Teapot. Once found, train binoculars to just under the triangle teapot lid. Good Luck!

Spotting the Green Giant

Catch a glimpse of the Green Giant with help of Venus.

Catch a glimpse of the Green Giant with help of Venus.

Wednesday, March 4, North Americans have a chance to observe the illusive green planet, Uranus.

Just below a super-birght Venus, the seventh planet from the sun will seem to pale in comparison. Standing at a fifth magnitude and just about five degrees below our sister planet, will be this pale-green dot.

Keen skywatchers can gander a peek in dark pristine skies away from the light dome of cities and don’t forget to bring binoculars as they will be your best friend as you find this secretive icy giant.

Moon Visits Leo

The Moon rides by Regulus, the heart of the lion on the night of Tuesday, March 3.

The Moon rides by Regulus, the heart of the lion on the night of Tuesday, March 3.

On Tuesday, March 3, the moon, now about 96% full will be seated next to the heart of the lion, Regulus.

Last week, the moon passed through the Bull, but this week, the moon will pay a visit to Leo. Separated by just four degrees in the sky, the bright star Regulus is really 79 light-years away, while the moon, only 1.3 light seconds distant. Regulus is the brightest star in the Leo constellation and rates as the 21st brightest star in the night sky and burns blue-white.

Imagine that when the light from Regulus began its journey to the Earth, the same year that Franklin D. Roosevelt won his second term as president of the United States and Margaret Mitchell published Gone with the Wind.

Mars and Venus cross paths over the next few nights.

Mars and Venus cross paths over the next few nights.

Just after sunset, on February 27, Mars and Venus will slowly part ways in the western sky.

On Friday, these two inner planets will be appear about 2.7 degrees apart but over the next few nights, Venus will rise while Mars will sink into the sunset.

The seventh planet from the sun, Uranus will be about 5 degrees from Venus. Using our sister planet as a guide post, sky gazers with telescopes or binoculars will be able to spy the green giant. While Uranus is four times larger in diameter than Venus, our twin planet outshines it by 10,ooo times. Good Luck!

Aldebaran and the Moon make a celestial portrait, Wednesday evening.

As the moon moves through the constellation Taurus, by Wednesday, February 25, it will be paired with the red eye of Taurus, the star, Aldebaran.

Visually, the red giant star will be parked just about a half of a degree from the quarter moon making for a stunning portrait, however, the moon is only about 1.27 light seconds away from Earth, Aldebaran lies about 66 light-years distant.
