Read more'Moon-forming' circumplanetary disk discovered in distant star system
Astronomers have made the first-ever observations of a circumplanetary disk, the planet-girding belt of dust and gas that astronomers strongly theorize controls the formation of planets and gives rise to an entire system of moons, like those found around Jupiter.

Read moreGalaxy clusters caught in a first kiss
For the first time, astronomers have found two giant clusters of galaxies that are just about to collide. This observation can be seen as a missing 'piece of the puzzle' in our understanding of the formation of structure in the Universe.

As if black holes weren't mysterious enough, astronomers using NASA's Hubble Space Telescope have found an unexpected thin disk of material furiously whirling around a supermassive black hole at the heart of the magnificent spiral galaxy NGC 3147, located 130 million light-years away.

Using nature's color palette from early Earth, astronomers have created a cosmic 'cheat sheet' in order to understand where discovered exoplanets may fall along their own evolutionary spectrum.

The collision of two neutron stars (GW170817) flung out an extraordinary fireball of material and energy that is allowing a team of astrophysicists to calculate a more precise value for the Hubble constant, the speed of the universe's expansion.

Supercomputer simulations of galaxies have shown that Einstein's theory of General Relativity might not be the only way to explain how gravity works or how galaxies form.

Read moreMassive stars grow same way as light stars, just bigger
Astronomers obtained the first detailed face-on view of a gaseous disk feeding the growth of a massive baby star. They found that it shares many common features with lighter baby stars. This implies that the process of star formation is the same, regardless of the final mass of the resulting star.

Read moreNew method may resolve difficulty in measuring universe's expansion
Astronomers have demonstrated how a combination of gravitational-wave and radio observations, along with theoretical modeling, can turn the mergers of pairs of neutron stars into a 'cosmic ruler' capable of measuring the expansion of the Universe and resolving an outstanding question over its rate.

Researchers using ALMA observed signals of oxygen, carbon, and dust from a galaxy in the early Universe 13 billion years ago. This is the earliest galaxy where this useful combination of three signals has been detected.
