In about five billion years, our Sun will exit its main sequence phase and transition to its red giant phase. At this point, the Sun will expand and consume the planets of the inner Solar System, including Mercury and Venus. What will become of Earth when this happens has been the subject of debate for …
As we discover more and more exoplanets – and the current total is in excess of 5,200 – we continue to try to learn more about them. Astrobiologists busy themselves analysing their atmospheres searching for anything that provides a sign of life. It is quite conceivable of course that the Universe is teeming with life …

Using spectra obtained by Webb, an international team examined three TRAPPIST-1 exoplanets during a series of flares.
According to a new study, the exoplanet 40 Eridani b (aka. “Vulcan”) was a false positive. Bad news for Star Trek fans, but possibly good for future exoplanet surveys.
Oxygen could indicate presence of life on another world, but for red dwarf planets finding oxygen isn’t enough.
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 …
A new study led by researchers from NASA’s Goddard Space Flight Center indicates that Proxima b would be likely to retain an Earth-like atmosphere.
A new study by researchers from St. Andrews University and the University of Strasbourg has shed light on why Venus has so few volcanoes compared to Earth.
With so many exoplanet discoveries around distant (and neighboring) stars, it might be time to assess what terms like “Earth-like” really mean.
According to an unnamed source, the ESO has discovered a habitable planet orbiting Proxima Centauri, making it the closest Earth-like planet discovered to date
