Hot Photos from Mercury's Close Encounter

MercurySat Jan 11 2025
You might think that Mercury is just our little neighbor. But it's not so simple. This small planet is brutal. It's so close to the Sun that it experiences extreme temperatures, from super hot to freezing cold. Plus, it's heavily beaten by solar radiation. So, imagine our excitement when the European Space Agency's BepiColombo probe got super close to Mercury for its last close look! It took pictures from just 295 kilometers above the surface. What did these pictures show? A lot of boundaries between brightly lit areas and dark ones. In the shadows, there's a layer of ice. This ice might have clues about Mercury's past and maybe even its future. The team behind BepiColombo will spend the next few weeks trying to understand these mysteries. The mission will enter its next phase after these flybys. In 2027, it will start collecting data. Until then, it has already given us a lot of new information about Mercury, thanks to six flybys. This tiny planet has secrets hiding under its surface. Like, why does it have a magnetic field? Or is there a lot of carbon that could be diamonds? And why is it slowly shrinking? The BepiColombo mission wants to answer these questions. It also took pictures of Venus's clouds on its journey. These images have shown Mercury as a world that gets darker over time but has moments of renewal with big impacts and volcanic eruptions. In one picture, there's a volcanic explosion site called the Nathair Facula. Nearby is a fresh crater called Fonteyn. In 2026, the BepiColombo Mercury Transfer Module will return to Mercury to release two orbiters. They will get really close to the planet and give us detailed pictures. So, get ready for more secrets from Mercury!

questions

    If Mercury is so hot during the day, does it have a 'Mercury's Got Talent' show for coolest craters?
    What are the potential implications of finding a thick layer of diamond on Mercury?
