"We've known for a while that binary star systems without giant planets have the potential to harbor habitable worlds. What we have shown here is that in a large fraction of those systems Earth-like planets can remain habitable even in the presence of giant planets," co-author Ian Dobbs-Dixon noted in the release.
"Our best candidate for hosting a world that is potentially habitable is the binary system Kepler-38, approximately 3970 light years from Earth, and known to contain a Neptune-sized planet," Georgakarakos noted. "Our study confirms that even binary star systems with giant planets are hot targets in the search for Earth 2.0. Watch out Tatooine, we are coming."

Five Binary Star Systems Could Host Habitable Planets | Digital Trends
The researchers identified five systems that are known to have multiple stars — Kepler-34, -35, -38, -64, and -413 — which could also support a habitable zone. In a single-star system, locating the habitable zone, or the region away from the star in which liquid water can exist on the surface of a planet is a relatively simple affair. But it’s more complex when two or more stars are involved.
"We've known for a while that binary star systems without giant planets have the potential to harbor habitable worlds,” said co-author Prof. Ian Dobbs-Dixon. “What we have shown here is that in a large fraction of those systems Earth-like planets can remain habitable even in the presence of giant planets.”
Planets easy to spot this week
Greetings everyone! Jupiter and Saturn are now easy finds in the pre-dawn sky. You'll just have to get up a little earlier this week to see them because the Sun is rising earlier and earlier. We lost 19 minutes of early morning darkness in March.
Most of us do our stargazing in the early evening sky. The last of the March full moon was on the 29th of that month, so there will be no moon in the early evening sky this weekend.
The states called this The Worm Moon due to the worms coming out at the end of winter. I think we should probably find another name!

Tonight the crescent moon appears under the bright red planet Mars. Both are in the zodiacal constellation Taurus. The moon appears above Mars tomorrow night.
Looking ahead you might get a glimpse of the brilliant planet Venus now low in the southwestern sky after sunset. Venus is tough to see right now. But if you are at Menemsha Beach or standing at the West Chop overlook after sunset you have a pretty good chance.
Venus is going to be the most dominant planet in our western sky through the year. Imagine spending a late evening on the beach and seeing the planet high in the sky.
We may be wrong about the atmosphere of alien planets, say scientists who cooked meteorites | The
Our understanding of alien planets might need revision, according to scientists who cooked meteorites .
The atmospheres of other rocky planets like our own Earth could be significantly different from the assumptions that researchers currently use when they create theoretical models of the ways they form, the new research suggests.
Scientists drew the conclusion after conducted novel research that saw them heat pieces of meteorite in a high-temperature furnace, and watch for the gases that were released. It is detailed in an article published today in the journal Nature Astronomy .
