Astronomers believe a massive star within the Kinman Dwarf galaxy has disappeared, and there are two possible explanations: either the giant, unstable star has been obscured by cosmic dust, or it is the first known star to collapse into a black hole without going supernova.

Astronomers have discovered a red dwarf star — approximately half the size of the sun that lies 11 light years away from us — exists within a multiplanet system, making it the closest to our solar system ever seen, according to research revealed Thursday.

New research suggests that as Pluto formed billions of years ago, a series of natural materials impacting on the planetary surface may have created liquid oceans beneath the dwarf planet’s icy crust — oceans that may still exist to this day.
Read moreThe quest to uncover other intelligent life in the Milky Way reached a new milestone Monday as researchers said they’ve charted out the number of civilizations in our galaxy that may be home to intelligent beings.

The Hubble telescope captured what astronomers thought was an exoplanet 25 light-years from Earth. Now they think Hubble captured the aftermath of an interstellar collision between two icy bodies.

While comets have long been thought to consist mostly of a frozen water core, research released Monday finds that one comet may instead hold a larger amount of carbon monoxide, helping astronomers better understand where it may have formed.

A trove of NASA spacecraft data from a visit to the farthest planet-like object in the solar system – a planetesimal in an icy region beyond the orbit of Neptune – reveals how planetary building blocks form over time, astronomers said in a trio of studies released Thursday.
