The Hubble Space Telescope's Wide Field Camera 3 revealed spectacular details of this spiral galaxy over 42 million light-years away from Earth.
The NASA Innovative Advanced Concepts (NIAC) program is funding a range of space tech studies in early development. In the future, they could assist space missions.
As the early universe cooled shortly after the Big Bang, bubbles formed in its hot plasma, triggering gravitational waves that could be detectable even today, a new study suggests.
Reference Heliocentrism places the sun at the center of the Solar System. This is the history of how scientists discovered our place and in the Solar System.
Reference The V2 rocket was the world's first liquid-propellant rocket. After claiming thousands of lives, how did it become a revolutionary breakthrough in rocket technology?
Reference This gas giant is the largest planet in the solar system, but just how big is Jupiter?
Reference The universe was born with the Big Bang as an unimaginably hot, dense point. SPACE.com offers an overview of the universe and its history, age and structure.
Reference Cosmology by definition is the branch of astronomy involving the origin and evolution of the universe, from the Big Bang to the future of the cosmos.
Reference This list of famous astronomers includes great scientists in history who mastered many fields and modern astronomers who helped popularize astronomy.
Reference Exactly how many stars are in the universe is impossible to know because we aren't sure of its scale.
