Our constant human presence in space nears 25 years
- In 2025, we mark 25 years of humans continuously inhabiting space since the first crew launched to the International Space Station on October 31, 2000.
- Anyone born after October 30, 2000, has never known a day without a human presence in space, according to the NASA History Office.
- The space race between the U.S. and Soviet Union led to milestones like Yuri Gagarin's orbit in 1961 and Valentina Tereshkova becoming the first woman in space in 1963.
- Neil Armstrong's historic moonwalk on July 20, 1969, marked the first time humans set foot on the moon, followed by 11 more lunar astronauts through 1972.
- Before the ISS, the Mir space station operated from 1986 to 2001, contributing to our continuous human presence in space.
- China's space station Tiangong, launched in 2021, joins the ISS in orbiting Earth, extending our human presence in space.
- The ISS's lifetime is limited, set to be deorbited in 2031, but plans for future space stations like lunar Gateway and Mars missions ensure our sustained presence in space.
- Humans have been consistently in space for 25 years, and with ongoing space missions, our presence in space is expected to continue.
- NASA plans to bring down the ISS in 2031, possibly guiding it to a watery demise in the Pacific Ocean near Point Nemo.
- Despite the ISS's end, the Tiangong space station and upcoming projects like lunar Gateway and Mars missions ensure our enduring human presence in space.

Hubble Comes Face-to-Face with Spiral’s Arms
- The Hubble Space Telescope recently captured an image of the spiral galaxy NGC 3596, located 90 million light-years away in the constellation Leo.
- NGC 3596 appears almost face-on from Earth, showcasing its neatly wound spiral arms with concentrations of stars, gas, and dust indicating active star formation.
- The formation of spiral arms in galaxies has puzzled astronomers, with varying structures and the 'winding problem' historically challenging to explain.
- Recent research suggests that spiral arms represent patterns of high-density and low-density areas rather than physical structures, with materials moving through them akin to cars in a traffic jam.

️ What Is the Event Horizon?
- The event horizon is an invisible shell around a black hole, marking the point where gravity is so intense that not even light can escape.
- Once you cross the event horizon, there is no going back, not even for light or a spaceship, due to the intense gravity.
- The size of an event horizon depends on the mass of the black hole, and tidal forces are less intense in more massive black holes.
- In 2019, the Event Horizon Telescope captured the first image of a black hole's shadow, proving the existence of event horizons.

The Dark Matter Delusion: How Physics Spent $50 Billion Chasing a Ghost
- The concept of dark matter was developed to explain the faster-than-expected movement of stars at the outer edges of galaxies.
- However, according to the article, this phenomenon can be understood through relativity, where time dilation effects in gravitational fields account for the discrepancy in star speeds.
- Despite the extensive search efforts and significant investments of over $50 billion in various experiments and projects, no concrete evidence supporting the existence of dark matter has been found.
- The author suggests that it is time to acknowledge that dark matter is a flawed concept and look towards alternative explanations rooted in relativistic theories to understand galactic dynamics.
