An Earth-sized planet in a star system very similar to our solar system may have an atmosphere after all, suggests new research using the James Webb Space Telescope.

The Trappist-1 system, first discovered in 1999, was in 2017 revealed by NASA to have seven potentially Earth-like rocky planets orbiting its star — including three in the not-too-hot, not-too-cold "habitable zone." At just 39 light-years distant, Trappist-1 is also close enough for astronomers to study using space telescopes.

Initial studies of the Trappist-1 planets using JWST have yet to yield convincing data on whether they are Earth-like. A paper published today in Nature Astronomy reveals that Trappist-1 b — the planet closest to its star — may not be the dark rocky planet without an atmosphere that it was initially thought to be.

In fact, the opposite may be true. New observations using JWST, this time in mid-infrared wavelengths of light, reveal two scenarios for Trappist-1 b:

An airless planet with a surface that shows no signs of weathering, which could indicate geological activity such as volcanism and plate tectonics.

A planet with a hazy carbon dioxide atmosphere is also viable — perhaps similar to Saturn's giant moon Titan.

The uncertainty of the new results is indicative of how difficult it is for scientists to characterize the nature of exoplanets — planets that orbit a star other than our sun — from multiple light-years distant.

Hi. Since I graduated from college, I've been trying to find cool new interesting things to do. Creating special effects wins as my favorite.

SANTA CRUZ, CALIFORNIA "Dad, did you ever imagine that your formula would become so famous?" I ask the kind-eyed, 91-year-old person next to me on the patio. My dad, Frank Drake, is quiet for a moment. Perhaps he's thinking back to the November day 60 years ago when he unceremoniously drafted a formula that went on to shape humankind's hunt for extraterrestrial civilizations.

World UFO Day, which is celebrated by some on January 24 and on July 2 by others, aims to raise awareness about ETs and UFO sightings.

UFO Hunting, With Harvard Data: Astrophysicist Advocates For Scientific Investigation

Avi Loeb: Two things. In 2017, there was an object — the first one that was identified from outside the solar system that arrived close to Earth — and it didn't look like anything we've seen before. It didn't look like a comet, it didn't behave like an asteroid. Loeb: Yes. And I thought maybe it's artificial in origin. And, in fact, I wrote a book about it, Extraterrestrial, that was published six months ago. And then a month ago, there was a report delivered to Congress saying: there are things in the sky above the U.S. whose nature is not identified.
