What if you placed an Earth-sized planet in a close orbit around an M-dwarf star? It’s more than an academic question since M dwarfs are the most numerous stars we know. A group of astronomers studying the planet GJ 1252b found an answer and it’s not pretty.

Will Mars finally answer, ‘Are we alone?’
We recently examined how and why the planet Venus could answer the longstanding question: Are we alone? Despite its harsh environment on the surface, its atmosphere could be hospitable for life as we know it. Here, we will examine the planet Mars, aka the Red Planet and the fourth planet in our solar system, which has been marveling sky watchers from ancient times to the present day.
Astronomers Find a “Marshmallow World”: the Lowest Density Gas Giant Ever Discovered
Exoplanet discovery space hosts all kinds of interesting “super” worlds. There are super-Earths, super-Neptunes, and, of course, Super-Jupiters. Recently, the WIYN telescope on Kitt Peak in Arizona did a follow-up observation of a gas giant discovered by TESS (the Transiting Exoplanet Survey Satellite). The world is fluffy and weird and it’s orbiting a red giant star. Oddly enough, it shouldn’t even exist. Yet, there it is happily orbiting a star some 580 light-years from Earth.
Mars Could Have Been Warm and wet, While Earth was Still a Glowing Ball of Molten Rock
Since the 1970s, the ongoing exploration of Mars has revealed that the planet has had a most interesting history. While conditions there are not hospitable to life today, scientists know Mars was once a much warmer, wetter place, with flowing water on its surface. According to new research led by the University of Arizona (UoA), Mars may have been a “pale blue dot” covered with oceans while Earth was still a ball of slowly-cooling molten rock. This discovery could allow for new research into a previously-overlooked period in Mars’ geological history and the formation and evolution of the Solar System.
