It seems like most of the planets have fled the evening scene. 2025 sees a decided lack of planetary action after sunset, just when many observers are out skywatching. Jupiter hangs high at dawn, and the crescent Moon is making its sunward dive this week, towards a rare triple conjunction with Regulus and Venus on Friday the 19th. […]
You know, if you take away the lack of air and water, the weaker Sun, the lower gravity, and the toxic soil, Mars isn’t all that bad of a place to live. And there are certainly worse places to live, like, I don’t know, Ohio (I’m allowed to say that because I grew up there). […]
In November 2019, Japan’s Hayabusa 2 mission departed the asteroid Ryugu after 1.5 years of observations. It had successfully collected a sample from the near-Earth object, and in December 2020, the spacecraft returned the valuable sample to Earth. If its mission had ended there, it would’ve been deemed one of the most successful and challenging […]
Before we get to Mars, we’re going to have to practice. And develop radical leaps in technology, but also in practice. A Mars mission will be utterly unlike anything attempted by humanity. We’re talking about a group of settlers, maybe as few as an initial team of four, travelling over a hundred million miles away […]
78 million years ago, a 1.6 km asteroid slammed into what is now Finland, creating a crater 23 km (14 mi) wide and 750 km deep. The catastrophic impact created a fractured hydrothermal system in the shattered bedrock under the crater. There’s evidence from other impact structures that in the aftermath of a collision, life […]
In a recent discovery, the James Webb Space Telescope (JWST) detected a massive stellar eruption measuring eight light-years across. This outflow, known as Sharpless 2-284 (Sh2-284 for short), is located about 15,000 light-years away in the outer reaches of the Milky Way. Based on an analysis by an international team of astronomers, this outflow appears […]
