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 ...

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 ...

NASA's Hubble Space Telescope detected material from a Pluto-like body spiraling into a white dwarf star 260 light-years away ...

NASA says its Hubble Space Telescope has detected a white dwarf star that consumed fragments of a Pluto-like object. Space ...

Earth has a number of mini-moons and quasi-moons. Mini-moons are objects that orbit our planet. But they make for fickle fans: They tend to swing around Earth for only a matter of months. One example ...

Kevin France, a professor of astrophysics at the University of Colorado Boulder, discusses the Habitable Worlds Observatory, ...

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 ...

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 ...
