Hubble uncovers a 'heavy metal' exoplanet shaped like a football
How can a planet be 'hotter than hot'? The answer is when heavy metals are detected escaping from the planet's atmosphere, instead of condensing into clouds.

A piping hot planet discovered by NASA's Transiting Exoplanet Survey Satellite (TESS) has pointed the way to additional worlds orbiting the same star, one of which is located in the star's habitable zone. If made of rock, this planet may be around twice Earth's size.

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.

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.

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.

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.
