2014 starts out with sunset view of a new Moon and a fading look at Venus, both captured together in this gorgeous image from astrophotographer Giuseppe Petricca.

“A wonderful sunset conjunction this evening from Central Italy,” Giuseppe wrote via email. “The Moon and Venus were both crescent, in an awesome sight! Some clouds entered the scene, and helped me filter the bright light of the ‘evening star’, revealing the little arch of the planet, from our point of view.” He added that this is “the youngest Moon I’ve ever captured, about 2% lit.”

Below is an image with an inset of Venus enlarged for a better view:

As our writer Bob King noted in his recent article, catch Venus now while you can, as it is slipping away: “As 2013 gives way to the new year, Venus winds up its evening presentation as it prepares to transition to the morning sky. Catch it while you can. Each passing night sees the planet dropping ever closer to the horizon as its apparent distance from the sun shrinks. On January 11 it will pass through inferior conjunction as it glides between Earth and Sun.”

Giuseppe’s images were taken with a simple non-reflex camera on a tripod, Nikon P90, ISO 100, f5.0, 1/2 exposure, which he says demonstrates “that with a little effort, you don’t need an expensive digicam to take this kind of shot.”

Beautiful!

Astrophoto: Crescent Venus in the Afternoon

In December, we challenged our readers to try and see Venus during the daytime. Sharin Ahmad from Kuala Lumpur, Malaysia started off the new year by nailing this awesome picture of a crescent Venus at just after noon local time today (January 2, 2014). “The usual cloudy Kuala Lumpur sky is teasing me again, giving me crystal blue sky today!” Shahrin said via email.

Based on SkySafari, Venus was about 3.2% illuminated, and about 15 degrees from Sun.

Equipment: Skywatcher 120ED (F=1800mm), and IMG132E video camera.

Here are other recent images of Venus submitted to our Flickr page by our readers:

Astrophoto: Nova Centauri 2013 Turns Pink

A recent naked-eye visible nova that erupted the first week in December 2013 is still showing its stuff, and this new “hot off the press” image from Rolf Wahl Olsen in New Zealand reveals its unusual color. “I managed to grab a close-up of Nova Centauri 2013 with my new 12.5″ f/4 scope,” Rolf said via email to Universe Today. “Curiously, I have only so far seen wide field images of this nova, and none that actually show it’s very unusual strong pink colour.”

Nova Centauri 2013 (in the Southern constellation of Centaurus) was discovered by John Seach from Australia on December 2, 2013, and it was visible at about magnitude 5.5. It subsequently brightened to reach a peak at magnitude 3.3.

Rolf’s image was taken today (it’s already Dec. 28, 2013 in New Zealand!) when the nova had faded to around magnitude 4.5. You can see a larger version here on Flickr or click the image above for a larger version on Rolf’s website.

Why is it pink?

“The nova appears pink because we are really viewing the light from an expanding shell of ionized hydrogen which emits strongly in both the red and blue part of the optical spectrum,” Rolf explained. “These emissions give the nova its strong pinkish colour, similar to emission nebulae which are also predominantly pink/magenta in hue.”

A nova is the result of a thermonuclear explosion on the surface of a white dwarf star in a tight binary system. The white dwarf accretes matter from its nearby companion and eventually the pressure from nuclear fusion blows off the accreted layers from the surface of the white dwarf. Contrary to a supernova where the star itself is blown apart and ceases to exist, a nova does not result in the destruction of the host star. The white dwarf may continue to accrete matter from its companion and the process may repeat itself sometime in the future.

The 2013 Super and Mini Moon Together in One Photo

Astrophotographer Giuseppe Petricca from Pisa, Tuscany, Italy managed to capture two of the very ‘special’ full Moons from 2013 and created a comparative mosaic. Here is both the 2013 “SuperMoon” in June – when the Moon is the closest to Earth in its orbit and visually largest – and the recent December 2013 “MiniMoon” — the most distant and visually smallest Full Moon of the year.

“I was amazed, to say the least, from the actual difference!” Petricca told Universe Today via email. “The motto ‘It’s not that evident until you, by yourself, get to notice it!’ applies perfectly to this situation.

While with naked eye, the full Moon seems about the same size every month, the difference in its visual size is clearly visible via pictures. Of course, the Moon itself doesn’t change size, it’s just how big or small it appears in the sky due to the eccentricities in its orbit around Earth.

The two pictures were both taken at the same focal length, with a simple non reflex camera, a Nikon P90, on tripod, with matching ISO speed and exposure, at ISO 100, f5.0, 1/200″. Both taken from Pisa, Tuscany, Italy.

Stunning Timelapse: Stargazing in the Canadian Rockies

One of our favorite photographers, Jack Fusco, recently visited Jasper National Park in Alberta, Canada, one of the worlds largest dark sky preserves. He went there on behalf of Travel Alberta, during the annual Night Sky Festival. “I was lucky enough to have two clear nights to explore and shoot as many photos as possible to create a short timelapse while there,” Jack told us via email. “In the end, I took over 2,000 photos at locations such as Lake Annette, Athabasca Glacier, Pyramid Lake, and many others. Out of all the places I’ve traveled in search for dark skies, Jasper definitely offered some of the best views I’ve ever seen. The sky in the Columbia Icefield area was unlike any I had witnessed before.”

Jack added that it was great to be around so many people that were excited about astronomy and preserving the night sky, and he’s already looking forward to going again in 2014, and astronaut Chris Hadfield is already lined up as a guest.

If you’re rushing about for the holidays, take a few minutes to enjoy a brief respite with this lovely timelapse. You can see more images and videos at Jack’s website.

Astrophotos: Geminid Meteor Shower Images from Around the World

It’s always one of the most reliable of the annual meteor showers, however, this year the Geminids had to compete with a bright waxing gibbous Moon, which reached Full Moon status today, just 3 days after the shower’s peak over the weekend. But as always, our astrophotographer friends were out in force to try and capture a meteor or two with their cameras. Take a look at our great gallery of shots from around the world, and thanks to everyone who submitted their images to Universe Today’s Flickr page!

Astrophoto: Zodiacal Light at Dawn

Sometimes, if you are lucky, dawn comes before the dawn. The zodiacal light – or false dawn, as it is sometimes called – is an ethereal light extending up from the horizon, sometimes seen about an hour before sunrise or an hour after sunset. At one time, it was thought this was an atmospheric phenomenon, but it’s more cosmic than that! Zodiacal light is sunlight reflecting off dust grains in space. These dust grains are likely left over from the same process that created Earth and the other planets of our solar system 4.5 billion years ago.

Alan Dyer captured this beautiful view of the zodiacal light on a recent trip to New Mexico. If you look closely you can see some other cosmic phenomena as well: “Mars is above centre and Saturn is just rising over the mountain ridge,” Alan wrote on Flickr. “Comet Lovejoy C/2013 R1 is at far left. The image includes the position (left of centre, above the mountains left of the Zodiacal Light) where Comet ISON (C/2012 S2) would have been had it survived passage around the Sun.”

Little Big Universe: Tilt-Shifted Astro Images Make Space Look Tiny

Hubble image of the Horsehead Nebula, "tilt-shifted" by Imgur user ScienceLlama (Original image credit: NASA, ESA, and the Hubble Heritage Team (STScI/AURA))

Aww, how cute! What an adorable little… nebula?

Although here it may look like it could fit in your hand, the Horsehead Nebula is obviously quite a bit larger – about 1.5 light-years across from “nose” to “mane.” But given a tilt-shift effect by Imgur.com user ScienceLlama, the entire structure takes on the appearance of something tiny — based purely on our eyes’ natural depth-of-field when peering at a small object close up. Usually done with Photoshop filters these days, it’s a gimmick, yes… but it works!

The original image was captured in infrared light by the Hubble Space Telescope and released in April 2013, in celebration of its 23rd anniversary.

Subaru Telescope Captures the Fine Details of Comet Lovejoy’s Tail

Comet ISON may be no more than just a cloud of icy debris these days but there’s another comet that’s showing off in the morning sky: C/2013 R1 (Lovejoy), which was discovered in September and is steadily nearing its Christmas Day perihelion. In the early hours of Dec. 3, astronomers using the 8.2-meter Subaru Telescope atop Mauna Kea in Hawaii captured this amazing image of Lovejoy, revealing the intricate flows of ion streamers in its tail. (Click the image above for extra awesomeness.)

According to a news story on the NAOJ website:

At the time of this observation, at around 5:30 am on December 3, 2013 (Hawaii Standard Time), Comet Lovejoy was 50 million miles (80 million km) distant from Earth and 80 million miles (130 million km) away from the Sun.

The entire image of comet Lovejoy was made with the Subaru Telescope’s Suprime-Cam, which uses a mosaic of ten 2048 x 4096 CCDs covering a 34′ x 27′ field of view and a pixel scale of 0.2”.

“Subaru Telescope offers a rare combination of large telescope aperture and a wide-field camera,” said a member of the observation team, which included astronomers from Stony Brook University in New York, Universidad Complutense in Madrid,  Johns Hopkins University, and the National Astronomical Observatory of Japan. “This enabled us to capture a detailed look at the nucleus while also photogenically framing inner portions of Comet Lovejoy’s impressive ion tail.”

Comet Lovejoy is currently visible in the early morning sky as a naked-eye object in the northern hemisphere.
