Parker Solar Probe's Mission The Parker Solar Probe, launched by NASA in 2018, ventures closer to the sun than any previous human-made object. Its mission is to unravel solar mysteries, particularly the dynamics of solar flares. Encased in a cutting-edge heat shield, the spacecraft can withstand temperatures nearing 2,500 degrees […]

Thermal Protection System The Parker Solar Probe's Thermal Protection System (TPS) is an engineering marvel crafted from carbon-carbon composite. Sandwiched between two carbon sheets, this material shields against temperatures reaching nearly 2,500 degrees Fahrenheit. Despite its protective capabilities, the TPS remains relatively lightweight at 160 pounds. The sun-facing side features […]

NASA's Artemis II: Reigniting Lunar Exploration NASA's Artemis II mission aims to reignite humanity's fascination with the Moon. This crewed lunar expedition, the first since Apollo 17, will test critical systems for future lunar landings. Four astronauts will journey aboard the Orion spacecraft around the Moon and back, preparing for […]

Dark Matter and Universe Expansion Dark matter intrigues scientists with its enigmatic properties and significant role in cosmic events. Comprising about 84% of the universe's mass, dark matter remains undetectable through direct means like light or electromagnetic forces. Its existence is inferred from gravitational effects on ordinary matter, orchestrating the […]

From ancient wooden contraptions to cutting-edge reusable rockets, the journey of rocketry reflects humanity's relentless pursuit of the stars.

Scientific Accuracy of Gargantua The black hole Gargantua from the film Interstellar is a dazzling spectacle, but how accurately does it reflect the science of black holes? While the movie's portrayal of the accretion disk shows a sleek, symmetrical ring of light, real accretion disks are turbulent and asymmetric, with […]

Habitability Potential Proxima Centauri b's position within its star's habitable zone sparks interest about its potential to harbor life. The planet orbits the red dwarf Proxima Centauri at a distance where liquid water could exist, but its circumstances may not be as straightforward as its location suggests. Liquid water is […]

Discovery of Proxima B Proxima b, a rocky planet possibly harboring water, orbits Proxima Centauri, the closest star to our sun. Discovered through Doppler data and radial velocity techniques, Proxima b's proximity at 4.2 light-years from Earth makes it an ideal subject for exoplanet studies. Astronomers using instruments like the […]
