Possibly. Certainly worth investigating further.

This is part of the plan for NASA to set up a deep space gateway using the Moon as a starting point. It is expected to be ready by 2020.
"These latter two components are what will allow for missions beyond the Earth-Moon system. Whereas the combination of the SLS, Orion and the DSG will allow for renewed lunar missions (which have not taken place since the Apollo Era) the creation of a Deep Space Transport and Martian Basecamp are intrinsic to NASA’s plans to mount a crewed mission to the Red Planet by the 2030s."

"An international team of researchers have found an infrequent variation in the brightness of a forming star. This 18-month recurring twinkle is not only an unexpected phenomenon for scientists, but its repeated behavior suggests the presence of a hidden planet.
This discovery is an early win for the James Clerk Maxwell Telescope (JCMT) Transient Survey, just one-and-a-half years into its three-year mandate to monitor eight galactic stellar nurseries for variations in the brightness of forming stars. This novel study is critical to understanding how stars and planets are assembled. The survey is led by Doug Johnstone, Research Officer at the National Research Council of Canada and Greg Herczeg, Professor at Peking University (China), and is supported by an international team of astronomers from Canada, China, Korea, Japan, Taiwan and the United Kingdom.
“This variation in the brightness or twinkle of the star EC 53 suggests that something large is disrupting the gravitational pull of the forming star. The fact that it recurs every 18 months suggests that this influence is orbiting around the star — it’s quite likely a hidden, forming planet,” says Doug Johnstone. It is thought that a companion planet is orbiting the star, and its passing gravitational pull disrupts the rate of the gas falling onto the forming star, providing a variation in the observed brightness, or light curve, of the star."
On a more personal note, I saw Jupiter just below Venus, briefly on Friday 9th November, early in the morning. This is one of the nice things about the EarthSky website.

The interesting part of it is that they are investigating for us unusual forms of survival. Traditional knowledge is being rewritten.Originally Posted by Dreamwoven

LoL. Moment of cuteness: a stellar nursery with twinkling stars.

Have you got a telescope?
I live among skyscrapers. One even forgets to look at the sky.

No I don't have a telescope, only a pair of binoculars,7x50, but without a stand for them image is rather wobbly...
Yay, I saw this early in the morning. I didn't see the proper conjunction, only the two planets close together: http://earthsky.org/tonight/venusjup...on-november-13
Have you tried fixing it somewhere high enough, on a ladder for example?

The conjunction should be visible today or tomorrow before sunrise, depending on where you live.

Now a bit more about the star of the day the "zombie star":

How mountains can cast shadows on clouds: http://earthsky.org/todays-image/pho...shadow-mystery
that wound take time to set up, depending on where the planet(s) happen to be. I don't have a step-ladder in the house.
