Planets are Finally Being Discovered Orbiting Farther From Their Stars
We don’t know much about exoplanets with long orbital periods, but we’re starting to learn.

200 light years away, “super earth” exoplanet K2-141b orbits a star so closely that its “year” is only 7 hours long. Not its day…its YEAR! K2-141b orbits a mere million kilometers from the fiery surface of its star. Earth is 150 million km from our Sun. Even Mercury, the planet closest to our Sun, is …
We have found more than 4,000 planets orbiting other stars. Life on distant worlds could find us in the same way.
That’s the kind of headline that can leave us scratching our heads. How can you see tree shadows on other worlds, when those planets are tens or hundreds of light years—or even further—away. As it turns out, there might be a way to do it. One team of researchers thinks that the idea could potentially …
By combining two exoplanet detection methods for the first time ever, the GRAVITY collaboration has confirmed the existence of a second planet around Beta Pictoris
Scientists are getting better at understanding exoplanets. We now know that they’re plentiful, and that they can even orbit dead white dwarf stars. Researchers are also getting better at understanding how they form, and what they’re made of. A new study says that some carbon-rich exoplanets could be made of silica, and even diamonds, under …

Can the galaxy’s dead stars help us in our search for life? A group of researchers from Cornell University thinks so. They say that watching exoplanets transit in front of white dwarfs can tell us a lot about those planets. It might even reveal signs of life.
New research using Hubble archive data shows that GJ 887, the nearby red dwarf star system with two exoplanets, might not be as calm and “boring” as we thought!
Strange New Worlds Imagine if a star could tell you it had planets. That would be really helpful because finding planets orbiting distant stars – exoplanets – is hard. We found Neptune, the most distant planet in our own solar system, in 1846. But we didn’t have direct evidence of a planet around ANOTHER star …

A new study by a team of astronomers and planetary scientists calculate that some stars could have as many as 7 habitable planets orbiting them!
