So what about a habitable moon around a distant gas giant? Kipping University College London has now gone to work on the question in relation to the Kepler space telescope.

Given our recent discussion of exomoon candidate Kepler b-i, a possible moon 2. Nakajima University of Rochester is first author of the paper describing this work. And flesh it out we will, as the precedent of the rapidly growing exoplanet count makes clear. The method produced a strong candidate indeed. We need as large a moon as possible, one having the maximum gravitational effect on its planet so that it produces the most observable signature in terms of transit timing variations of the host world around its star. Working with colleagues at Tokyo Institute of Technology and the University of Arizona, Nakajima has concluded that rocky planets larger than 6 Earth masses are unlikely to produce large moons, as are icy planets larger than a single Earth mass. Rocky planets smaller than 6?

In addition, a valid email address is required for a comment to be considered. Our model predicts that the moon-forming disk needs to be initially liquid or solid rich, supporting the canonical moon-forming impact model.

The Moon's current phase for today and tonight is a Waxing Gibbous phase. Visible through most of the night sky setting a few hours before sunrise. The phase lasts about 7 days with the moon becoming more illuminated each day until the Full Moon. This September Full Moon will be the forth and final supermoon of During a Waxing Gibbous the moon rises in the east in mid-afternoon and is high in the eastern sky at sunset.

But many of our greatest discoveries start with the simple act of observing. Jupiter plows through the Pleiades on March 14, a chance to spot Mercury at month's end along with a subtle lunar eclipse, and a comet worth keeping an eye on! March 13 — The Moon joins Jupiter tonight in the west, following sunset. They make a great pairing through binoculars. March 14 — Tonight the crescent Moon moves through the Pleiades star cluster, creating a dazzling sight for skywatchers observing with binoculars. March - Northern Hemisphere viewers have their best chance of the year to spot Mercury in the evening sky. Look for it shining brightly, low in the west, starting half an hour after sunset. March — A subtle lunar eclipse called a penumbral eclipse will cause a slight decrease in the Moon's brightness tonight. It's usually difficult to see, but you might see the difference if you look before the eclipse and then at the peak.

The official reason from the International Astronomical Union is that astronomers expect to find numerous exoplanets, so many in fact that it would be impractical to name them. Credit: Nakajima et al. Among other criteria for selection: Comments must be on topic, directly related to the post in question, must use appropriate language, and must not be abusive to others. This finding could shake things up, because thus far we have been examining a search space largely defined by gas giants. Also, the Moon around a gas giant might be rare or formed probably because most large bodies past the snow line become gas giants or ice giants. Image : A habitable exomoon would offer an exotic vista, a view that may be more common in the galaxy than we have previously imagined. For the full list, see the paper. For many years this site coordinated its efforts with the Tau Zero Foundation. Now, a habitable exomoon around a early K or G star may be a more promising prospect. The red-orange colors represent the entropy of the mantle material forsterite. To Andy, regarding your previous comment about exomoons could you please describe it in more detail. Search Search.

The Moon and planets have been enlarged slightly for clarity. On mobile devices, tap to steer the map by pointing your device at the sky.

A radial velocity variation gives only a minimum mass: we cannot be sure that these objects are necessarily exoplanets at all. Seems like an odd choice to me. Recent Posts. Dave Weeden on October 27, at This transit timing variation TTV is a signal that could be used to spot an exomoon. What exciting times we live in! I really suspect that the signal-noise ratio leans heavily toward noise here. The primary criterion is that comments contribute meaningfully to the debate. The official reason from the International Astronomical Union is that astronomers expect to find numerous exoplanets, so many in fact that it would be impractical to name them. Not convinced — rings very hollow to me. My optimistic guess is the latter half of Rocky planets smaller than 6?
