Mysterious Tessera Terrain on Venus Could Be the Remains of Giant Ancient Impacts
In the chaotic early days of the Solar System, planets endured a relentless barrage of cosmic collisions. Most of the rocky worlds including Mercury, Mars, and Earth's Moon still bear scars of these ancient impacts in the form of vast craters and impact basins. However, Venus has been a strange outlier, with scientists finding no evidence of large craters over 300 kilometers wide. This missing piece of Venus's violent past has puzzled researchers for years.
A recent study now suggests that these long-sought impact structures may indeed exist on Venus but look very different from our expectations. Geologist Vicki Hansen of the Planetary Science Institute and her team propose that a peculiar formation called the Haastte-Baad Tessera could be Venus’s largest and oldest impact structure.
