Watch: Earth’s Wobble Creates a Twilight Zone Shadow

The view from the ISS as it orbits over the termination line known as the twilight zoneNASAA daily photo taken from September 2023 to September 2024 offers an intriguing view of the twilight zone transition caused by the Earth's 23.5-degree axial tilt during its orbit around the Sun.Without the Earth's axial tilt, we wouldn't...

Super Magdrive Rocket Thrusters Operate Using Heavy Metal

The Super Magdrive gives us ACME vibesMagdriveThe most prevalent metal known to humanity is iron. It can be found everywhere, not just on Earth but also in space. Astro engineers have recently discovered how to utilize iron—and nearly any metal, for that matter—as plasma rocket fuel.It's well-established that certain metals can ignite explosively. Lithium...

NASA is Moving Forward with Plans to Establish a Time Zone on the Moon

Credit: PixabayFortunately, NASA is advancing plans to implement a standardized time zone on the Moon. The proposed Coordinated Lunar Time (LTC) would help schedule missions and explorations, making future efforts to establish a permanent base on the lunar surface somewhat easier.While the concept has been previously discussed, NASA has announced plans to collaborate with...

Lab Discovery Presents New Challenge in the Search for Alien Life

Credit: PixabayThe most probable method for detecting life on a distant exoplanet is by identifying a biosignature. This involves analyzing the atmospheric spectra of the planet to find the distinctive spectral pattern of a molecule that can only be produced through biological activity.Although it seems straightforward, detecting life on exoplanets is far from simple....
