A pair of recent studies conduct in-depth analyses of Jupiter-sized exoplanets, also known as Exo-Jupiters, and were published in Nature Communications and The Astronomical Journal, respectively. The study published in Nature Communications was conducted by an international team of researchers and examines how Exo-Jupiters could be more common than previously thought, while the study published in The Astronomical Journal was conducted by one researcher and examines exoplanetary system, HD 141399, and how it is comprised entirely of Exo-Jupiters with no additional planets.

How did Earth evolve from an ocean of magma to the vibrant, life-supporting, blue jewel it is now? In its early years, the Earth was a blistering hot ball of magma. Now, 4.5 billion years later, it’s barely recognizable.

Is it possible to find exoplanets out there in the vast expanse, which are young molten globes much like young Earth was? How many of them can we expect to find? Where will we find them?
