A star called TOI-2155 lies around 1,350 light-years (839 trillion miles) from Earth. It is a little bigger, heavier and hotter than the sun, and it is not particularly interesting or unusual in itself.
Searching for habitable worlds beyond our solar system involves more than having a planet orbit within its star's habitable zone, the region where temperatures could be just right for liquid water to exist on the surface. ...
Exoplanet atmospheres have become prime targets for astrobiologists in the search for life beyond Earth. This is because exoplanet surfaces can't be directly imaged yet, so astronomers must get creative in how they search ...
For the first time, NASA's TESS (Transiting Exoplanet Survey Satellite) mission has identified a planet orbiting a distant star thanks to its warping of space-time. Unlike the star-hugging transiting planets TESS regularly ...
Using the Hobby-Eberly Telescope at McDonald Observatory, astronomers have taken a closer look at a nearby exoplanet and discovered it may be more Earth-like than previously thought. The planet, known as GJ 3378b, orbits ...
Artificial intelligence (AI) is continuing to have a disruptive impact on ever more parts of humanity. But what does it mean in the long run? A new paper, available as a preprint on arXiv from Austrian researcher Sergey Ivliev, ...
Giant mirrors in space have been a staple of science fiction for decades. But so far, there's been very little work looking at the actual physics behind the concept—possibly because we're still so far from making them ourselves. ...
Within their planetary systems, stars are continuously shaping their orbiting planets through gravity, radiation and magnetic forces. So far, this relationship has appeared to be a one-way street.
It feels like every few months we get to report on another academic paper singing the praises of the Solar Gravitational Lens (SGL). Partly, this is due to Dr. Slava Turyshev's astounding productivity in pumping out academic ...
Uranus and Neptune remain two of the most mysterious objects in the solar system, primarily because they have been visited only by NASA's Voyager 2 spacecraft in 1986 and 1989, respectively. Their "ice giant" moniker comes ...
