The Rosette Nebula

Look to the east of mighty Orion and you’ll see the constellation Monoceros, the Unicorn. While its stars are faint, Monoceros holds a small treasure chest of superb deep-sky sights for backyard stargazers. Perhaps the most striking is the Rosette Nebula, an achingly beautiful blossom of glowing gas and dust where new stars are forming.  The Rosette is an immense nebula, some three times larger than the Orion Nebula and three times farther away.  As you see in the image above by Terry Hancock, the nebula overlaps the star cluster NGC 2244 which has formed within the nebula and blown a bubble to give us a look inside. While hard to see the Rosette visually, even in large telescopes, the nebula is an excellent photographic target and the cluster is a superb sight [Read more…] about The Rosette Nebula

A ‘Christmas Star’

December 22, 2019 by Brian Ventrudo Filed Under: Celestial Events

Brilliant Sirius over a snow-covered spruce tree in the wee hours of an icy morning looks a lot like the Christmas Star. Let’s all enjoy a fine holiday and a happy new year!

Exploring a Comet, Very Close Up

September 9, 2019 by Brian Ventrudo Filed Under: Solar System

The Comet from Christian Stangl on Vimeo.

The Rosetta spacecraft made its final maneuver around the Comet Churyumov-Gerasimenko (67p) in 2016 and made a controlled hard landing. Rosetta had accompanied the comet for more than 2 years, measured valuable scientific data, brought a lander on to the comet’s surface and took vast numbers of pictures.

In 2017 the European Space Agency released over 400,000 images from the Rosetta mission. Based on these images, motion designer Christian Stangl and composer Wolfgang Stangl worked together to create this short (but quite astonishing) film.
The sequences are digitally enhanced real-footage from the probe.

Watch the beauty of an active alien body, far out in the dephts of our solar system.

Is the Universe Too Dangerous for Life?

It’s a question that inevitably arises in conversations about the cosmos: does life exist elsewhere in the universe?

For those who hope the answer is “yes”, the harvest of exoplanets by NASA’s Kepler Space Telescope and other telescopes over the past decade has been hugely encouraging. As of mid 2019, in the small slice of sky under its exacting gaze, analysis of Kepler’s measurements found more than two thousand extrasolar planets, and all telescopes have confirmed some 3,700 exoplanets. Extrapolating these results, astronomers estimate our Milky Way galaxy alone might hold some 10 billion planets that may have the temperature and composition to harbor habitable life. With that much real estate, many believe that complex or even intelligent life must have formed on at least some of these? [Read more…] about Is the Universe Too Dangerous for Life?

See the ‘Craters of Apollo 11’

July 18, 2019 by Brian Ventrudo Filed Under: Solar System

The astronaut Edwin (Buzz) Aldrin at Tranquility Base on July 20, 1969.

As the world celebrates the 50th anniversary of the still astonishing Apollo 11  moon landing, we backyard stargazers can also get in on the fun (indeed many of us grizzled amateur astronomers can trace our interest in the night sky to the space program of the 1960s). With a modest telescope and good seeing, nearly anyone with a little observing experience can see the region of the Moon where Neil Armstrong and Buzz Aldrin briefly walked, and observe the three tiny craters named for the two famous moonwalkers and their crew mate Michael Collins who remained alone in lunar orbit to pilot the Apollo 11 command module [Read more…] about See the ‘Craters of Apollo 11’
