December’s Stars and Planets

Comet ISON Update

As we wrote last month, Comet ISON was to make its closest approach to the Sun on November 28, 2013, which was Thanksgiving Day in the United States.  The comet flew very close to the Sun and thus faced the Sun’s tremendous gravitational and radiation forces.  As we stated, it was impossible to predict what would happen to the comet upon its encounter with our nearest star.  Unfortunately, the latest reports are that the Sun has pretty much destroyed this comet, which many astronomers had dubbed the “comet of the century.”

But do not fret: There’s still plenty to see in the night sky this December!

The planet Venus is particularly bright this month.  In fact, if you observe Venus on a clear, dark night (without moonlight and far from city lights) while snow remains on the ground, hold your hand about a foot off the ground: You might just see Venus casting a shadow on the ground! Venus is the really bright ‘star’ you will see above the west-southwestern horizon after sunset.

Meteor Shower

One of the best meteor showers of the year occurs this month: The “Geminid Meteor Shower,” s0-called because the shooting stars all appear to fly out of the constellation Gemini.

The Geminids are active between Dec. 4 and 17, and peak on Dec. 14.  But, because the Moon will be fairly bright the night of Dec. 13/14, the best time to see the Geminids that night will be during the hour, or so, before sunrise.  However, you should still see shooting stars no matter what time of the night you look for them in the Dec. 4-17 time period.

No telescopes or binoculars required!  To observe shooting stars, the best thing to do is lie down on a lawn chair or blanket and look up!  Depending on where you live in the world, be sure to bring along plenty of winter clothing or mosquito repellant!

Follow the Moon through the Constellations

Did you know you can use the Moon to help identify constellations (areas of the night sky) like Aries, Taurus and Sagittarius?  Follow us on Twitter where we Tweet what constellation the Moon is in each night.  (Note that during certain times of the month, the Moon will not appear during the night hours, and so we do not Tweet info about the Moon at those times of the month.)

 

Finding your star in the night sky

Stars are located within constellations, which are just areas of the night sky. Scorpius, Aries and Taurus are examples of constellations. Your Name A Star Live Star Certificate displays the name of your constellation. You can use our online World Constellation Guide to determine if you can see your constellation during the evening hours (between sunset and midnight). Of course, you’ll need a telescope to see your star. But you can see your constellation without the use of a telescope. You can also find your constellation by using our Virtual Planetarium™ astronomy software. A planisphere is another useful device.

Comet makes closest approach to Sun on Thanksgiving Day

Comet ISON shines brightly in this image taken on the morning of Nov. 19, 2013. This is a 10-second exposure taken with the Marshall Space Flight Center 20″ telescope in New Mexico. The camera there is black and white, but the smaller field of view allows for a better “zoom in” on the comet’s coma, which is essentially the head of the comet.

The comet makes its closest approach to the Sun on Nov. 28, 2013 — Thanksgiving Day in the U.S. Should the comet survive its close encounter with our star, the comet could put on quite a show in December.  Its tail would demonstrate the effect of the physical pressure of sunlight — the force the Sunjammer solar sail will use to fly into deep space.  Sunjammer will carry our customers’ star names into the final frontier.  Read more about the comet and Sunjammer in our blog post from early November entitled, “The Comet & the Sunjammer Solar Sail.

And check out this neat video (below) of Comet ISON rising over the Canary Islands just a few days ago!

X-Class Solar Flare

This spectacular image of the sun shows yet another powerful solar flare that the sun has emitted in recent weeks.  The image was taken Nov. 19 by NASA’s Solar Dynamics Observatory.  Your star name will fly on board a new solar observing spacecraft, the Sunjammer solar sail, which will give us even earlier warning of solar storms that could adversely affect Earth.

Solar flare
An X1-class flare erupts from the right side of the sun in this image captured by NASA’s Solar Dynamics Observatory on Nov. 19, 2013. The flare erupted from a region that produced many flares in its two-week journey across the face of the sun, and is shown here just before rotating out of view.

This solar flare peaked at 5:26 a.m. EST (10:26 am GMT) Nov. 19. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth’s atmosphere to physically affect humans on the ground, however — when intense enough — they can disturb the atmosphere in the layer where GPS and communications signals travel.

This flare is classified as an X1.0 class flare. “X-class” denotes the most intense flares, while the number provides more information about its strength. An X2 is twice as intense as an X1, an X3 is three times as intense, etc.

This flare came from an active region numbered AR 1893 that is just rotating out of sight over the sun’s right side. Increased numbers of flares are quite common at the moment, since the sun’s normal 11-year activity cycle is ramping up toward solar maximum conditions. Humans have tracked this solar cycle continuously since it was discovered in 1843, and it is normal for there to be many flares a day during the sun’s peak activity.

November’s Stars and Planets

Venus is the bright ‘star’ you’ll see in the west at sunset.  It will be in the Name A Star Live constellation Sagittarius throughout November.  The Moon will help you identify Venus the night of November 6.

Venus and the Moon
Venus will be near the slender, crescent Moon the evening of Nov. 6.  Just look west after sunset and look for Venus, which will be the brightest ‘star’ in the western sky.  Venus will be among the stars of the Name A Star Live constellation Sagittarius.
The elusive planet Mercury is visible over the eastern horizon at mid-month. The ringed planet Saturn will be beneath it.  You may get a glimpse of Comet ISON by first finding these two planets toward the end of the month.  See our blog article about Comet ISON for more information.

The Comet & the Sunjammer Solar Sail

Stargazing
Stargazing is a fun family activity — especially when you can see a comet together!

Astronomers have high hopes for a new comet called “Comet ISON,” which is predicted to reach peak visibility in late November and into December.  Although predicting how bright a comet will appear is notoriously difficult, we may be in for quite a show!  Below we discuss how you can view the comet.  Assuming the comet makes for an interesting site in the night sky, it would help illustrate how the Sunjammer solar sail will be propelled through space, carrying your star’s name on a mission that could last for millions of years!

Hubble Catches a Spiral in the Air Pump

Galaxy
This new Hubble image shows a nearby galaxy that, like true love, is beautiful, full of wonder and everlasting!

Lying more than 110 million light-years away from Earth in the constellation of Antlia (The Air Pump) is the spiral galaxy IC 2560, shown here in an image from NASA/ESA Hubble Space Telescope. At this distance it is a relatively nearby spiral galaxy, and is part of the Antlia cluster — a group of over 200 galaxies held together by gravity. This cluster is unusual; unlike most other galaxy clusters, it appears to have no dominant galaxy within it.

In this image, it is easy to spot IC 2560’s spiral arms and barred structure. This spiral is what astronomers call a Seyfert-2 galaxy, a kind of spiral galaxy characterized by an extremely bright nucleus and very strong emission lines from certain elements — hydrogen, helium, nitrogen, and oxygen. The bright center of the galaxy is thought to be caused by the ejection of huge amounts of super-hot gas from the region around a central black hole.

There is a story behind the naming of this quirky constellation — Antlia was originally named “antlia pneumatica” by French astronomer Abbé Nicolas Louis de Lacaille, in honor of the invention of the air pump in the 17th century.

Why people name stars

Starry Night

Why do people come to websites like NameAStarLive.com and ‘name’ stars?

Love is certainly one of the main reasons: Couples have gazed at the stars above for countless generations.  Like true love, the stars are beautiful and eternal, they are a powerful source of energy and light in an otherwise lonely existence, and their sparkle brings joy to our hearts.   When we view the heavens above, we join with generations – past and future – that have gazed/will gaze upon the same heavenly view in awe and wonder.

September’s Stars and Planets

If you’re an early bird, you can see the planets Mars and Jupiter in the eastern sky at sunrise this month!  If you have a telescope, consider looking at Mars during the mornings of September 8 and 9 as the red planet moves through the famous “Beehive Cluster” of stars in Cancer.  Both Mars and Jupiter will appear as bright points of light in the eastern sky before sunrise.

Mars and Jupiter
Mars and Jupiter are visible in the Name A Star Live constellations Cancer and Gemini, respectively.  Just look east during the hours before sunrise and look for the two bright ‘stars’ over the horizon.

Beautiful Space Imagery

Here are some beautiful space photos and videos that have been posted on the Internet recently. Enjoy!

Large Magellanic Cloud
A beautiful star-forming region in a nearby galaxy!

The European Southern Observatory’s (ESO) Very Large Telescope has captured an intriguing star-forming region in the Large Magellanic Cloud — one of the Milky Way’s satellite galaxies. This sharp image reveals two distinctive glowing clouds of gas: red-hued NGC 2014, and its blue neighbour NGC 2020. While they are very different, they were both sculpted by powerful stellar winds from extremely hot newborn stars that also radiate into the gas, causing it to glow brightly.
