The discovery of Ammonite might have disproven the existence of Planet Nine, but it's also given researchers insights into the outer edges of the solar system.| Sciencing
Astronomers have spotted the third interstellar object seen to be traversing our solar system, it's named 3I/ATLAS and it comes from the core.| Sciencing
If you're planning a trip to space, you'd better take a few things along. Actually, you'll need more than a few things -- you'll need everything a human being needs to survive in an environment that lacks food, water, air, room to move and gravity. Unless you're planning to be outside the solar system, your space ship should provide protection from solar radiation. If you're taking a long trip, bring something to keep yourself occupied.| Sciencing

Even though Venus is the closest planet to Earth, it is often eclipsed in popular culture by another neighboring planet, Mars. Though Mars has similar surface conditions to Earth, Venus appears more like Earth's twin -- similar in size, density and mass. Venus may be Earth's celestial neighbor, but it still takes a spacecraft over a year to reach the planet, whose orbit takes it closer to the sun.| Sciencing
Tides are the constant rising and falling of sea levels across the globe. Newton’s laws of gravity say that two bodies in the universe are attracted to each other by gravitational pull. The laws express how the mass and distance between those bodies affect the attraction. The sun and moon both hold sway over movements on Earth, and the attraction between all three -- sun, moon and Earth -- affect the tides.| Sciencing
The moon is Earth's longtime, familiar companion, the story of when and how it got there is actually a bit of an unanswered question in astronomy.| Sciencing
Stars, such as the sun, are large balls of plasma that can produce light and heat in the area around them. While these stars come in a variety of different masses and forms, they all follow the same basic seven-stage life cycle, starting as a gas cloud and ending as a star remnant.| Sciencing
The sun has been our source of energy for billions of years. While some wonder if it will eventually explode, it won't, but its death will be much slower.| Sciencing
