- by Jake ParksThe phenomenon of a Full Moon arises when our planet, Earth, is precisely sandwiched between the Sun and the Moon. This alignment ensures the entire side of the Moon that faces us gleams under sunlight. Thanks to the Moonโs orbit around Earth, the angle of sunlight hitting the lunar surface and being reflected back toContinue […]

Universe Today
- New data from NASAโs Hubble Space Telescope shows definitive evidence of a dwarf galaxy merging with the young Milky Way galaxy in the earliest phases of its evolution. This finding extends our knowledge of our galaxyโs history 1.8 billion years farther back in time than before.
- Planets form in protoplanetary disks, reservoirs of gas and dust around young stars. But young stars are a little hyperactive, and they emit powerful winds that can dissipate the gas. So planets, especially gas giants, are in a race against time to form. They only have a few million years before the gas is gone.
- Recent searches for the technosignatures of hypothetical Dyson Spheres again turn up empty.
- When we think of weather forecasts, we instinctively think of weather on Earth like rain or shine. However, we rarely consider weather forecasts from outside of the Earth, also called space weather. While space weather often results in the awe-inspiring aurora located at the northern and southern latitudes, we often forget the negative impacts of […]
- Some of the strangest weather in the solar system doesnโt happen on Earth, or even Jupiterโs Great Red Spot – it happens in the interior of the Ice Giants like Neptune and Uranus. Specifically, scientists have long believed that, at certain pressure and temperatures, it literally rains diamonds inside of these planets. And for the […]
- The ESA's Sentinel satellites captured a 76 sq. km. chunk of ice breaking off from Greenland's Petermann Glacier. They watched the cracks and deformations happen in real time leading up to the calving. While calving is normal, it's happening more often, and this is another clear sign that the Arctic is rapidly changing due to […]
