THE coming week is a great time to look for planets. A new moon on 28 October means no moonlight and, with the exception of Neptune , every planet is visible at some point in the coming days. Even distant Uranus, which at 8 pm GMT on 27 October will be a mere 2.8 billion kilometres away.
Venus is the easiest to find, with an apparent magnitude of -4.6. In the magnitude scale, objects with lower numbers are brighter!

A Churning 'Molten Blob' of Planet May Be Easier to Find. Here's Why. | Space
The smaller a planet , the more difficult it is to spot — which is frustrating for scientists hoping to find Earth-like worlds.
That's why a team of researchers set out to determine what planetary traits would make a world a little easier to identify!

Use it to locate a planet , the Moon, or the Sun and track their movements across the sky . The map also shows the phases of the Moon, and all solar and lunar eclipses.!! Their analysis suggests that molten worlds with atmospheres full of water or carbon dioxide will be more easily observed by instruments that will be available to scientists soon.

And that's a boon for observers: If two planets have the same mass but one has a magma ocean and the other doesn't, it could be about 5% larger across, making it easier to spot. And a molten world is more likely to be leaking water and carbon dioxide from that liquid rock out into a developing atmosphere.
Those two molecules are easily released by molten rock, but they are also the sort of thing that future telescopes like NASA's James Webb Space Telescope are being designed to detect!

What is the difference between a planet-satellite system as we have with the Earth and Moon, versus a binary planet – two planets orbiting each other in a cosmic do-si-do?
In 2018, two astronomers from Columbia University reported the first tentative observation of an exomoon – a satellite orbiting a planet that itself orbits another star. One curious feature was that this exomoon Kepler-1625b-i was much more massive than any moon found in our solar system!

It has a mass similar to Neptune and orbits a planet similar in size to Jupiter.
Astronomers expect moons of planets like Jupiter and Saturn to have masses only a few percent of Earth. But this new exomoon was almost a thousand times larger than the corresponding bodies of our solar system – moons like Ganymede and Titan which orbit Jupiter and Saturn, respectively!

Ancient stars shed light on Earth's similarities to other planets | UCLA
Earth-like planets may be common in the universe, a new UCLA study implies. The team of astrophysicists and geochemists presents new evidence that the Earth is not unique. The study was published in the journal Science on Oct. 18.
“We have just raised the probability that many rocky planets are like the Earth, and there’s a very large number of rocky planets in the universe,” said co-author Edward Young, UCLA professor of geochemistry and cosmochemistry.
The scientists, led by Alexandra Doyle, a UCLA graduate student of geochemistry and astrochemistry, developed a new method to analyze in detail the geochemistry of planets outside of our solar system. Doyle did so by analyzing the elements in rocks from asteroids or rocky planet fragments that orbited six white dwarf stars.
“We’re studying geochemistry in rocks from other stars, which is almost unheard of,” Young said.

(CNN) Just 11 light years from earth is the GJ 15 A star system with two planets orbiting a red-dwarf star. This makes it the closest solar system to Earth that contains multiple planets.
