Interesting Scientific Discoveries in the News

Why the Greenland Vikings vanished– possibly globalization and climate change (brought on by a massive volcano).

“Giant oarfish are the longest known living species of bony fish, reaching a length of 56 feet (17 meters). They can weigh up to 600 pounds (270 kilograms).” National Geographic has more. I’ve been reading about them this week because last week a couple large ones washed up on the shore here in the Philippines. They are said to be omens of coming earthquakes, and it is true that a few days later, we felt a couple large enough to discombobulate our piece of mind during the movement.

Nasa telescope spots seven earthsized planets revolving around a single star in a habitable zone.
“In contrast to our sun, the TRAPPIST-1 star – classified as an ultra-cool dwarf – is so cool that liquid water could survive on planets orbiting very close to it, closer than is possible on planets in our solar system. All seven of the TRAPPIST-1 planetary orbits are closer to their host star than Mercury is to our sun. The planets also are very close to each other. If a person was standing on one of the planet’s surface, they could gaze up and potentially see geological features or clouds of neighboring worlds, which would sometimes appear larger than the moon in Earth’s sky.

The planets may also be tidally locked to their star, which means the same side of the planet is always facing the star, therefore each side is either perpetual day or night. This could mean they have weather patterns totally unlike those on Earth, such as strong winds blowing from the day side to the night side, and extreme temperature changes.”
