Astronomers revisiting old observations from NASA’s Hubble Space Telescope have uncovered a clue that may solve a decades-old ...

Imagine the Sun shedding its outer layers not as a gentle breeze but as bursts of material flung in different directions. Each burst nudges the Sun slightly, and the planets respond by shifting their ...

As published in The Astrophysical Journal Letters, theoretical astrophysicists Konstantin Batygin and Jim Fuller of Caltech, ...

A Jupiter-sized world just 7.5 light-years away is cloudy, chemically complex and, it turns out, more like home than anyone ...

Taiwanese scientists have re-analyzed data from previous space observations and identified a celestial body that could be the hypothesized ninth planet in the Solar System — Planet Nine. If this ...

Scientists may have made a breakthrough in the search for Planet Nine. They have discovered a faint object whose brightness ...

A strange chemical signature in old Hubble observations may point to a planet that formed after its star had already died. Astronomers found unusually high levels of niobium around the white dwarf HS ...

After being born of mostly just hydrogen and helium, a scant 14-ish billion years later the Universe is full of weird planets of wildly varying makes, shapes, and sizes. Well, maybe not shapes, ...

Could black holes have planets? New research says yes, they could. New simulations suggest massive planets could form in the ...

It has about a 1 percent chance of leaving the Solar System within the next 5 billion years and a fraction of the models show ...

Radio signals emanating from Beta Pictoris b suggest that this young and massive exoplanet has a strong magnetic field and ...

Astronomers have found that part of the outer solar system appears tilted by roughly 15 degrees, a distortion that should ...
