Pluto's unusual eccentricity and tilt is likely due to its interactions with neighboring Neptune and other giant planets, ...

Astronomers using NASA’s Hubble Space Telescope have witnessed a rare cosmic meal: a white dwarf star consuming pieces of a ...

Dwarf planet 2023 KQ14, Ammonite, has a stable orbit that challenges the hypothesis of the mysterious Planet Nine.

First, let’s compare the orbital characteristics of Pluto with those of other planets. Pluto has an orbital eccentricity (the degree to which its orbit deviates from a perfect circle) of 0.25, while ...

Normally when a medium-size star dies, it blasts away the bulk of material in its system. The Hubble discovery was surprising ...

The Big Bang may have spawned these theoretical black holes, whose lives are thought to end in a burst of extremely energetic particles.

Hubble has captured a dense, burned-out star in the act of consuming a Pluto-like object. Happening some 260 light years from Earth, the new observation, published in the Monthly Notices of the Royal ...

Astronomers have uncovered the chemical fingerprint of a frozen, water-rich planetary fragment being consumed by a white ...

Astronomers have discovered a distant white dwarf star consuming an icy, Pluto-like planetesimal. This finding reshapes our understanding of what can survive post-star death.

This cosmic drama offers a unique glimpse into the future fate of our own Solar system and highlights the power of Hubble’s ultraviolet vision to probe stellar remains that would otherwise go ...

Methane gas may signal an atmosphere or geological activity on a distant dwarf planet located at the outer edge of the Solar System. A research team led by the Southwest Research Institute has ...

In our nearby stellar neighborhood, a burned-out star is snacking on a fragment of a Pluto-like object. With its unique ultraviolet capability, only NASA's Hubble Space Telescope could identify that ...
