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

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

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

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 detected the chemical fingerprint of a frozen, water-rich planetary fragment being devoured by a white dwarf ...

Summer 2015 was marked by a unique astronomical event, which occurs approximately once in the history of astronomy. The New ...

The Kuiper Belt is loosely defined as a doughnut-shaped swath of space beginning just beyond the orbit of Neptune and ...

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

The findings suggest Earth’s geological story was partly written in the stars – specifically, in the spiral arms of our home ...

In a study published in the Monthly Notices of the Royal Astronomical Society (MRNAS), astronomers from the University of Warwick, Europe, and the United States found strong evidence that ...

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 ...
