Amazing facts — Amazing Universe Facts

Fact 1: Stars are classified into various types based on their spectral characteristics, temperature, and luminosity.

Fact 2: The most common type of star is a main-sequence star, like our Sun, which fuses hydrogen into helium in its core.

Fact 1. Interplanetary Travel Challenge: The journey to Mars is a complex feat, with the distance between Earth and Mars varying from 54.6 million kilometers (33.9 million miles) to over 401 million kilometers (249 million miles) during different points in their orbits.

Fact 1 - Solar flares are explosive releases of energy from the Sun's surface. These events occur when magnetic energy that has built up in the solar atmosphere is suddenly released, emitting intense radiation across the electromagnetic spectrum.

Fact 1 - Kalpana Chawla and the Space Shuttle Columbia (2003): Indian-born astronaut Kalpana Chawla was among the crew members who lost their lives when the Space Shuttle Columbia disintegrated during reentry into Earth's atmosphere.

Fact 1 - Astronauts consume specially prepared space food, including items like shrimp cocktail and thermostabilized entrees.

Fact 2 - The space station has a water recovery system that purifies urine into drinking water for astronauts.

Fact 1: The first-ever spacewalk was conducted by Soviet cosmonaut Alexei Leonov on March 18, 1965, during the Voskhod 2 mission.

Fact 2: The longest single spacewalk was conducted by Russian cosmonaut Anatoly Solovyev, lasting 8 hours and 56 minutes in 1990.

Fact 1: Apollo 11, the historic space mission, marked the first successful crewed landing on the Moon on July 20, 1969.

Fact 1: The ISS is a habitable artificial satellite orbiting Earth, serving as a microgravity and space environment research laboratory.

Fact 2: Launched in 1998, the ISS represents a partnership involving space agencies from the United States (NASA), Russia (Roscosmos), Europe (ESA), Japan (JAXA), and Canada (CSA).

Fact 1: Black holes are formed when massive stars exhaust their nuclear fuel and collapse under their own gravitational pull, concentrating mass in a tiny, infinitely dense point known as a singularity.

Fact 2: The boundary surrounding a black hole is called the event horizon. Once an object crosses this boundary, it is irreversibly drawn into the black hole.
