Existence of an Earth-like planet around a dead sun offers hope for our planet's ultimate survival

The discovery of an Earth-like planet 4,000 light years away in the Milky Way galaxy provides a preview of one possible fate for our planet billions of years in the future, when the sun has turned into a white dwarf, and ...

Observations provide crucial insights into the nature of a white dwarf–brown dwarf binary

Using the Hubble Space Telescope (HST), astronomers have performed spectrophotometric observations of an eclipsing white dwarf–brown dwarf binary known as WD1032+011. Results of their observational campaign, published September ...

Webb discovers six new 'rogue worlds' that provide clues to star formation

Rogue planets, or free-floating planetary-mass objects (FFPMOs), are planet-sized objects that either formed in interstellar space or were part of a planetary system before gravitational perturbations kicked them out.

In six new rogue worlds, Webb Telescope finds more star birth clues

The James Webb Space Telescope has spotted six likely rogue worlds—objects with planetlike masses but untethered from any star's gravity—including the lightest ever identified with a dusty disk around it.

Tracking a newly discovered hypervelocity star spotted by citizen scientists

It may seem like the sun is stationary while the planets in its orbit are moving, but the sun is actually orbiting around the Milky Way galaxy at an impressive rate of about 220 kilometers per second—almost half a million ...
