A newly discovered planet that should be too big to have formed around a tiny star is throwing into question what researchers know about planet formation.
The primary objective of CHEOPS is to better understand the planets that we’ve already found. And its mission is now in full swing.
NASA scientists have discovered a new planet orbiting around a nearby star that is in a habitable zone. But does this planet have liquid oceans that can support life?
Sometimes it is difficult to take a photograph of an exoplanet because the star illuminating it is too bright. Now there is a new ‘deluminator’ telescope that can block out the extra light.
Scientists who discovered planets in far off stellar systems and the fundamentals of the Big Bang Theory have earned the 2019 Nobel Prize in Physics.
The discovery of a huge planet orbiting a small star challenges our understanding of planet formation.
The geological and biological archives of the Earth shed light on both the distant past of our planet and allow us to imagine its future.
The new planet is believed to be orbiting Barnard’s Star, a red dwarf that’s not visible to the naked eye but one of the closest stars to our Solar System.
Google’s artificial intelligence has been taught to look for planets around other stars. It’s already making new discoveries that scientists have missed.
A solitary planet in an eccentric orbit around an ancient star may help astronomers understand exactly how such planetary systems are formed.
Several of the newly-discovered exoplanets orbiting a small star appear to be locked in an intricate dance that hints at how such planetary systems can form.
If there’s life on one of the Earth’s seven sisters, chances are it has spread to all of them.
Over the last 20 years, advances in the field of exoplanet discovery have excited the imaginations of scientists and enthusiasts alike. But we’re in position to know yet whether a planet is habitable.
