We have discovered thousands of exoplanets in recent years, including some that are Earth-sized and potentially habitable. But we haven’t seen many of those worlds.
Fortunately, that will change in the near future. New telescopes scheduled to be launched in the next decade, such as the Nancy Grace Roman telescope, will be able to directly image Earth-sized exoplanets. But as a new study shows, that by itself won’t be enough.
Exoplanets: How to avoid planet confusion based on our solar system | New Scientist
If aliens could confuse Earth for another planet, we could be mistaking our impressions of exoplanets
Taking a picture of a far-off world may not be enough to identify what sort of planet it is. We know this because from outside our solar system, every other planet except for Jupiter could be mistaken for Earth at some angles.
Runaway rogue planets might be our best chance for finding aliens
Rogue planets are kind of like Han Solo. Instead of taking off in a beat-up starship they won in a game of sabacc, they somehow get kicked out of their star systems, unless they were never captured by one to begin with, and roam freely throughout space.
"We do not yet know what the closest rogue planet to Earth, but these planets are very faint because they don't emit much light," said Lingam. "Based on general observations and our own data, it is plausible that the nearest rogue planet is only about 0.1 light years from Earth."

EarthSky | Circumtriple planet suspected: a planet orbiting 3 stars
GW Orionis, or GW Ori, is a triple star system located at the head of Orion the Hunter . A massive protoplanetary disk surrounds the triple star system.
The scientists published their study on September 17, 2021, in the peer-reviewed journal Monthly Notices of the Royal Astronomical Society .
View from Mars Hill: 12 facts about Jupiter, the king of the planets | Columnists | azdailysun.com
Jupiter continues to shine brightly in the eastern skies just after sunset. Here are a dozen fun facts about the king of the planets:
• Jupiter is the largest planet in the solar system. It contains twice the mass of all the other planets combined. About 1,300 Earths could fit inside Jupiter and one would have to line up about 11 Earths to equal one Jupiter diameter.
Discovering Earth-like planets may be harder than scientists thought | TweakTown
Humans have always wondered if we are alone in this vast universe we call home and the discovery of Earth-like planets that are some of the best places to look to answer that question.
While it may seem as simple as pointing a large telescope into the void of space to find one of these planets, it's certainly not as easy as it sounds. In fact, it may be much harder than researchers have anticipated.
