Happy Birthday, Hans Christian รrsted๐ฅณ
#Onthisday, we celebrate the birth of Hans Christian รrsted, a Danish physicist born on August 14th. รrsted's contributions to the field of physics were truly remarkable. He is best known for his groundbreaking discovery in 1820, when he observed the interaction between electric current and a magnetic needle, leading to the formulation of the principle of electromagnetism.
๐ฎรrsted's work revolutionized our understanding of the relationship between electricity and magnetism, laying the foundation for future scientific advancements. On this special occasion, we reflect on รrsted's significant contributions to physics and express our gratitude for his enduring legacy.

Aleksader Wolszczan and Dale Frail observed two rocky planets orbit around PSR B1 257+12,which is a pulsar in the constellation Virgo. As they are constantly getting bombarded by the radiation of the dead parent neutron star, these planets can't support any organic life. These kinds of celestial bodies are known as exoplanets

Astro-Questionโ Does life violate the second law of thermodynamics? Comment your ideas below! Share: @AstroMechanics
Answer๐ก
Living organisms, despite their organization, still adhere to the second law of thermodynamics. Life's processes increase overall entropy, from formation to death, as energy is consumed, waste is generated, and internal order is maintained. This refutes mystical beliefs and confirms that life operates within the boundaries of physical laws.
๐In conclusion, the statement emphasizes that living organisms do not violate the second law of thermodynamics. Instead, they operate in accordance with it by contributing to the overall increase in entropy.

โโWhat would happen if a nuclear bomb was detonated in space?
When a nuclear bomb explodes on Earth, the huge release of radiation triggers the rapid expansion of air around it, causing the intense blast wave that wreaks so much destruction.
๐In the vacuum of space, the lack of air means the principal destructive effects come not from the blast, but instead from the particles and radiation pouring out of the bomb, which dump their energy as heat on striking the target
