Scholz's Star, a binary star system, passed through the Oort Cloud approximately 70,000 years ago, potentially dislodging some comets but having a relatively minimal overall impact due to its small ...

Manual cardiopulmonary resuscitation (CPR) techniques, including the "handstand" method, are ineffective in microgravity due to the lack of a counter-force to compression, resulting in insufficient ...

If we all woke up one morning to find the Moon missing, most of us probably wouldn’t notice. Those who live near the oceans would find the tides reduced, but not completely absent. While the Moon does ...

Long-term (1988-2017) Earth-based radar observations of Venus, utilizing data from Arecibo and Green Bank Observatories, yield an average rotation period of 243 days and 30.5 minutes. This average ...

Betelgeuse, a red supergiant star, will eventually explode as a supernova. The supernova will be as bright as a half-moon for over three months, visible even during the day. The explosion poses no ...
