The Sun accounts for almost ninety-nine point eight six percent of the Solar System's total mass.

The central star of our system is so massive that it completely dominates local gravity. Jupiter, the largest planet…

There is an exoplanet that may be composed largely of diamond.

The planet 55 Cancri e, which orbits a Sun-like star, is carbon-rich, and due to high pressure and temperature…

The footprints left on the Moon could last for millions of years.

Since the Moon has no atmosphere, there is no wind or water to cause erosion, so the Apollo astronauts' footprints…

A teaspoon of neutron star material would weigh billions of tons.

Neutron stars are incredibly dense. A volume the size of a teaspoon of their material would weigh about six billion…

Venus rotates on its axis in the opposite direction to most other planets in the solar system.

This retrograde rotation causes the Sun to rise in the west and set in the east on Venus, a unique phenomenon among…

The Sun contains approximately ninety-nine point eight six percent of the total mass of the solar system.

This gravitational dominance is what keeps all planets, asteroids, and comets in orbit around it, making the Sun by…

The footprints left by Apollo astronauts on the Moon will likely remain there for millions of years.

Since the Moon has no atmosphere, there is no wind or water to cause erosion. Unless a meteorite hits the exact spot…

Neutron stars can spin at a rate of over 700 rotations per second.

When a massive star explodes and its core collapses, the conservation of angular momentum causes the resulting…

There is a massive water vapor cloud around a quasar that holds 140 trillion times the water in Earth's oceans.

Astronomers observed the quasar APM 08279+5255, over 10 billion light-years away, and discovered this massive cloud…

The footprints left on the Moon by the Apollo astronauts will likely remain there for millions of years.

The Moon has no atmosphere, wind, or liquid water, the main agents of erosion on Earth, so the marks left in the…

A teaspoon of a neutron star would weigh billions of tons on Earth.

Neutron stars are the incredibly dense remnants of massive stars that have collapsed. Their matter is so compacted…

The footprints left on the Moon by astronauts will remain there for millions of years.

The Moon has no atmosphere, wind, or liquid water, which are the main agents of erosion on Earth. Without these…

Approximately one million Earths can fit inside the volume of the Sun.

The Sun is a star of massive dimensions. Its radius is about one hundred and nine times larger than that of the…

The footprints left on the Moon by astronauts may remain there for millions of years.

The Moon has no atmosphere, wind, or liquid water, so there are no natural erosion processes to erase the marks…

The footprints left on the Moon by Apollo astronauts will remain there for millions of years.

The Moon has no significant atmosphere, which means there is no wind or water to cause erosion. Without these natural…

Saturn's rings are composed mainly of water ice, not solid rock.

Observations from the Cassini mission confirmed that Saturn's rings are made of billions of water ice particles…

A footprint left by an astronaut on the Moon can last millions of years.

The Moon has no atmosphere, wind, or liquid water to cause erosion. Without these erosive agents, marks on the lunar…

There is a giant alcohol cloud in space.

In the Sagittarius B2 star-forming region, astronomers detected a cloud containing billions of liters of ethyl…

The Moon is moving away from Earth at a rate of about three centimeters per year.

The tidal interaction between Earth and the Moon transfers energy, causing the lunar orbit to gradually expand. This…

A teaspoon of material from a neutron star would weigh approximately six billion tons on Earth.

Neutron stars are the ultra-dense remnants of massive stars that have collapsed. Their gravity is so extreme that…

The footprints left on the Moon by Apollo astronauts will likely remain intact for millions of years due to the lack of atmosphere and erosion.

The Moon has no atmosphere, wind, liquid water, or significant tectonic activity. Without these erosive agents, there…

Saturn has an average density lower than that of water, meaning it would theoretically float if placed in a sufficiently large ocean.

Saturn's density is about 0.687 grams per cubic centimeter, while water is 1 gram per cubic centimeter. This low…

The Moon is moving away from the Earth by about 4 centimetres per year.

The Moons gravity causes tides in the Earths oceans. This movement creates friction that transfers energy from the…

A teaspoon of material from a neutron star would weigh a billion tonnes on Earth.

Neutron stars are the ultra-dense remnants of stars that exploded. Their matter is so compressed that a teaspoon…
