Space Science on Instagram: "The "Pale Blue Dot" is a photograph of Earth taken by the Voyager 1 spacecraft on February 14, 1990. Carl Sagan popularized the image, which shows Earth as a tiny speck from 3.7 billion miles away. The phrase, along with Sagan's reflection on the photo, serves as a reminder of our planet's fragility and the importance of humility, compassion, and global unity. The photograph was taken as part of NASA's "Family Portrait" series of images of the Solar System. Earth app

Explaining The Universe on Instagram: "Spacecraft can use the gravity of planets or moons to change their velocity and direction through a technique called a gravity assist or gravitational slingshot. This method takes advantage of the motion and gravitational pull of a celestial body to boost or alter a spacecraft’s path without using extra fuel. When a spacecraft flies close to a planet or moon, it is pulled by the body’s gravity, gaining speed as it falls toward it and losing speed as it move

Explaining The Universe on Instagram: "About 4.5 billion years ago, during the chaotic early days of the solar system, a Mars-sized protoplanet named Theia is believed to have collided with the young Earth. This catastrophic impact released unimaginable energy, melting both worlds and blasting huge amounts of debris into space. The collision destroyed the early Earth’s original surface, reshaping the planet and forming a new, molten world. Much of Theia’s material merged with Earth’s core and ma

Our Third Dimension | Space Science Universe on Instagram: "Which planet represents you?😄😵‍💫 Info: Mercury’s axis tilt is almost zero at 0.01°, and it rotates once every 58.7 Earth days at about 10 km/h. Venus rotates backwards compared to most planets, with a tilt of 177° and a slow rotation taking 243 Earth days. Earth spins once every 23 hours and 56 minutes with a tilt of 23.44°, rotating around 1,574 km/h. Mars has a 25.19° tilt and rotates in 24 hours and 37 minutes at 866 km/h. Jupiter

BOS Planet on Instagram: "☄️ 3I Atlas just flew past Mars—And it’s getting closer! 3I/ATLAS, only the third interstellar visitor ever spotted in our Solar System. It swung closest to Mars on October 3, 2025 (~29 million km from Mars) and is racing toward the Sun for perihelion around October 29–30 (≈ 1.36–1.4 AU). At that point it’ll be ripping along at ~68 km/s. Afterward, it passes 0.65 AU from Venus (Nov 3) and makes its closest approach to Earth on December 19 at ~1.8 AU—far, but perfect for

Prehistoric Planet on Instagram: "Neanderthals evolved in Europe and Asia while modern humans - our species, Homo sapiens - were evolving in Africa. Judging from fossil evidence from Sima de los Huesos in northern Spain and Swanscombe in Kent, the Neanderthal lineage was already well-established in Europe by 400,000 years ago. The species ranged widely in Eurasia, from Portugal and Wales in the west across to the Altai Mountains of Siberia in the east. Neanderthal populations were adaptable, liv
