Moon and Antares | StarDate On-line
The Moon takes goal on the coronary heart of the scorpion tonight — the brilliant star Antares. It’s beneath 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 crammed with younger stars. Lots of them, like Antares, are massive and vivid. And the area additionally could also be crammed with planets. A current examine reported dozens of doable “rogue” planets — worlds that don’t orbit a star.
As a result of they’re far-off from any stars, the free-floating planets mirror nearly no starlight, making them faint. However the planets are younger, in order that they’re nonetheless heat. Which means they produce a glow of their very own, primarily at pink and infrared wavelengths. Astronomers found the doable 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 had been roughly as huge as Jupiter, the enormous of our personal photo voltaic system. And so they discovered as many as 100 extra objects that may be planets.
The planets may have fashioned as a cloud of fuel and mud that was too small to make stars collapsed to kind smaller our bodies. Alternatively, the planets may have been born round stars, then kicked away by encounters with different planets. Or maybe there’s another clarification for the wayward planets in that busy area of the galaxy.
