Innovative way to stabilise and control the spacecraft Kepler 2, needed to monitor distant stars with transiting planets
The largest man-made structure in space ever is celebrating its birthday and looking optimistically in the future. This video shows its wonderful journey thru’ its last 15 years.
The whole project did take long to realise. This infographic shows the history of its construction and development.

NASA’s Kepler space telescope scanned a very tiny portion of the sky for planets and came out with 3538 known and candidate exoplanets. This beautiful multiple juxtaposition of these candidates are shown to be moving to Beethoven’s Moonlight Sonata. Very poetic, yet scientific!

It has been successfully put into Earth’s orbit. In few weeks time, it will be gradually put into departure hyperbolic trajectory, when real journey to Mars will start. It will take around 300 days to reach Mars, where it will be put in Martian orbit. The details of the mission and its primary scientific objectives are explained in the following document.

The Great Nebula in Orion Natural/False Color Hybrid, a photo by Terry Hancock www.downunderobservatory.com on Flickr.
An amazing colorful depiction of Great Nebula in Orion. How it is achieved can be found in the details below

Yes yet another version of M42 "The Great Nebula in Orion" this time I have combined the natural color of RGB filters together with the narrow band using HST (Hubble Palette) formula with SII assigned to red channel, H-Alpha to green channel and OIII to blue channel with what I think gives a very interesting result.
I have to say my previous image hubble palette version is a bit of a dissapointment but unfortunately when we apply the narrow band colors from filters according to the Hubble type of palette this is the result and to some it looks like candy and very un naturale. Of course the end result is much dependant on data and processing. You should see what it looks like in CFHT palette…forget it, I am too embarrased to post it.
My conclusion is that for me The Hubble Palette works very well on some objects but on others like M42 not so well. Again it is a matter of personal opinion and taste.
Shooting with these narrow band filters together with LRGB allowed me to create this false/natural color hybrid which introduced color and detail not visible in natural RGB wavelengths using my equipment.

Astronomer’s Paradise is the first episode of Atacama Starry Nights timelapse movie series. Cerro Paranal is truly an astronomers paradise with its stunningly dark, steady and transparent sky. Located in the barren Atacama Desert of Chile it is home to some of the world’s leading telescopes. Operated by the European Southern Observatory (www.eso.org) the Very Large Telescope (VLT) is located on Paranal, composed of four 8 m telescopes which can combine their light to make a giant telescope by interferometry. Four smaller auxiliary telescopes, each 1.8 m in aperture, are important elements of the VLT interferometer.
Walking on the desert near Paranal between the scattered stones and boulders on the pale red dust feels like being on Mars but under the Earth sky. It is an amazing experience to be under an ideal night sky, a pure natural beauty unspoiled by urban lights. On Cerro Paranal in the Atacama Desert you look all around the horizon and there is no prominent sign of city lights, neither direct lights or light domes. There are not many locations left on this planet where you can still experience a dark sky like this. I have been to similar dark skies in other continents from the heart of Sahara in Algeria to Himalayas or islands in the Pacific. But what makes Atacama beat others is being dry and clear for so many nights per year. Paranal was selected for cutting edge astronomical observations also because of the sky transparency and steady atmospheric condition which let astronomers peer in to tiny details in the deep cosmos using giant telescopes.

There were many attempts to explore Mars using Space missions. As of July 2007 the success rate was 47%. Interestingly, Soviets were the first to attempt it, but Americans were the most successful ones. In coming centuries, the exploration will look different with China and India coming into play. The following infographics tells the whole story:

No doubt Earth is the most habitable of all, but it does not hold the perfect score. Luckily, it’s not human who is making Earth less than perfectly habitable, but rather it is due to “tidal flexing“.
