Encyclopedia
Solar System is the gravitationally bound system comprising the Sun and the objects that orbit it, either directly or indirectly. Of those objects that orbit the Sun directly, the largest eight are the planets, with the remainder being significantly smaller objects, such as dwarf planets and small Solar System bodies. Of the objects that orbit the Sun indirectly, the moons, two are larger than the smallest planet, Mercury.
The Solar System formed 4.6 billion years ago from the gravitational collapse of a giant interstellar molecular cloud. The vast majority of the system’s mass is in the Sun, with most of the remaining mass contained in Jupiter. The four smaller inner planets, Mercury, Venus, Earth and Mars, are terrestrial planets, being primarily composed of rock and metal. The four outer planets are giant planets, being substantially more massive than the terrestrials. The two largest, Jupiter and Saturn, are gas giants, being composed mainly of hydrogen and helium; the two outermost planets, Uranus and Neptune, are ice giants, being composed mostly of substances with relatively high melting points compared with hydrogen and helium, called volatiles, such as water, ammonia and methane. All planets have almost circular orbits that lie within a nearly flat disc called the ecliptic. — Wikipedia

- Moon’scapes - There’s no denying that it’s been a rough week for many Earthlings. On the other hand, it’s been a great week for anyone who spends their time more preoccupied with the Moon than with more earthly concerns. That’s because there’s a treasure trove of news about our lunar realm. For example, NASA’s Goddard Media Studios … Continue reading Moon’scapes

- Consciousness likely not unique to earthlings,...on June 11, 2026 at 12:20 pm
Does consciousness depend on flesh and blood? The answer is almost certainly no, according to Eric Schwitzgebel, a distinguished professor of philosophy at the University of California, Riverside. In a new working paper, Schwitzgebel and Jeremy Pober, a former UCR graduate student who is now a postdoctoral researcher at the University of Lisbon, assert that consciousness is likely possible in life forms made of very different stuff. Think of the five-limbed alien with a rocklike exterior in the […]
- On the hunt for cosmic dawn and the universe's...on June 11, 2026 at 12:00 pm
After only four short years, NASA's James Webb Space Telescope (JWST) and observational cosmologists like Richard Ellis at University College London (UCL) have pushed the cosmic lookback time to an era when the universe's very first stars and galaxies are within observational reach.
- Lab-created 'moon' rock could help scientists...on June 10, 2026 at 10:30 pm
The moon may look unchanged from afar, but its surface is constantly reshaped by microscopic impacts and a steady stream of particles from the sun, a process known as space weathering. Now, Georgia Tech researchers have recreated one of those weathering sources, solar wind, in the lab—offering new insight into how the lunar surface evolves. Their work is published in The Planetary Science Journal.

No matter the time or vantage point, from a pre-Neolithic cave to a post-lockdown London high-rise, the predictability of the night sky has always been humanity's symbol of permanence and reassuring stability.
- Small optical component could change how...on June 10, 2026 at 6:00 pm
A new telescope technology—measuring just 6 millimeters (0.24 inches) in diameter—could improve how future space missions study and monitor the sun while simplifying onboard hardware and reducing costs.
