Moon and Antares | StarDate On-line
The Moon takes goal on the coronary heart of the scorpion tonight — the intense star Antares. It’s under the Moon at dusk, however nearer to the left of the Moon as they set, within the wee hours of the morning.
The area round Antares is full of younger stars. A lot of them, like Antares, are huge and vibrant. And the area additionally could also be full of planets. A current examine reported dozens of potential “rogue” planets — worlds that don’t orbit a star.
As a result of they’re distant from any stars, the free-floating planets replicate virtually no starlight, making them faint. However the planets are younger, in order that they’re nonetheless heat. Meaning they produce a glow of their very own, primarily at purple and infrared wavelengths. Astronomers found the potential planets by analyzing 20 years of observations by telescopes on the bottom and in house.
It took some cautious work to pick the planets. However the astronomers reported discovering about 70 planets that have been roughly as huge as Jupiter, the enormous of our personal photo voltaic system. They usually discovered as many as 100 extra objects that may be planets.
The planets might have shaped as a cloud of gasoline and mud that was too small to make stars collapsed to type smaller our bodies. Alternatively, the planets might have been born round stars, then kicked away by encounters with different planets. Or maybe there’s another rationalization for the wayward planets in that busy area of the galaxy.
