- by Brooks MendenhallSometime between April 11 and May 22, 2024, a comet or asteroid roughly the height of a three- to six-story building smashed into the Moon, leaving a crater 728 feet (222 meters) wide in its wake. A year and a half later, a NASA scientist spotted it, making it the largest newly formed crater humansContinue […]
- 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 Moonβs orbit around Earth, the angle of sunlight hitting the lunar surface and being reflected back toContinue […]
- by Elisa NeckarOn Sept. 24, 1970, Luna 16 blazed a new trail in lunar sample collection β one traversed by robots. Although the Apollo astronauts had collected lunar samples on their missions, Luna 16 was the first instance of samples being gathered and returned to Earth fully robotically, with no astronauts (or cosmonauts) involved. After blasting offContinue […]

- by Mark ZastrowAloke Palsikar, taken from Pie Town, New Mexico The Crescent Nebula (NGC 6888) is an emission nebula about 5,600 light-years away in Cygnus. Its distinctive shape was formed by fast stellar winds from the Wolf-Rayet star at its center colliding with material the star shed earlier in its life. The astroimager took 3 hours ofContinue […]
- by F. Michael WitkoskiLight exhibits some of the strangest properties in our cosmos. It manifests as both a wave and a particle, and its speed in a vacuum is invariant. While physicists now fully grasp the way light interacts with the universe, this understanding has not always been so solid. Untangling its peculiar behavior has led to theContinue […]

- A new study reveals that Jezero Craterβs enigmatic βMargin Unitβ was shaped by a complex sequence of ancient lakes, groundwater systems, and hydrothermal fluids.
- Rocket launches are some of the most violent travel methods man has ever created. They generate millions of pounds of thrust and convert that into intense g-forces. Humans must undergo serious training to withstand those experiences, but machines have to do so as well, but by design rather than training. If a delicate mirror or […]
- Docking with the ISS may seem simple. However, actually doing so is a showcase in how difficult orbital mechanics can be. Itβs equivalent to traveling down a highway at 28,000 km/hr and parallel parking into an open garage on a multi-billion dollar laboratory traveling at the same speed. If you try to accelerate forward you […]
- Galaxies and their stars in the early Universe look a lot weirder than those we see today, and astronomers want to know why. A team of researchers at the University of Utah decided to survey certain stars in nearby galaxies as analogs of those that existed when the Universe was still in its infancy. The […]
