Pluto may have an ocean under its surface
An analysis of images of the dwarf planet's surface and computer simulations of its interior have led researchers to propose a "hot start" scenario for Pluto's formation as the solar system, including Earth, took shape.

Does intelligent life exist on other planets? Technosignatures may hold new clues
In 1995 a pair of scientists discovered a planet outside our solar system orbiting a solar-type star. Since that finding—which won the scientists a portion of the 2019 Nobel Prize in Physics—researches have discovered more than 4,000 exoplanets, including some Earth-like planets that may have the potential to harbor life.

Super-Earths are real and they could be an even better place to live than Earth
There are many Earth-like planets where we could start interstellar colonies. But life on a super-Earth would be very different than life on Earth.

Europe's Sun mission makes first close pass
Europe's Solar Orbiter (SolO) probe makes its first close pass of the Sun on Monday, tracking by at a distance of just over 77 million km. SolO was launched in February and is on a mission to understand what drives our star's dynamic behaviour. The close pass, known as a perihelion, puts the probe between the orbits of Venus and Mercury.

Your Guide to Saturn
The real Lord of the Rings is Saturn, a massive outer planet boasting a set of rings about 27 Earths wide. Being a gas giant like Jupiter, Saturn shares many of its attributes: a strong magnetic field generated by churning metallic hydrogen deep inside, raging storms in its gaseous upper atmosphere, and a diversity of planet-like moons that are worlds unto themselves. Saturn’s rings and larger moons are visible even from small backyard telescopes.

Why astronomers now doubt there is an undiscovered 9th planet in our solar system
Planet Nine is a theoretical, undiscovered giant planet in the mysterious far reaches of our solar system. The presence of Planet Nine has been hypothesized to explain everything from the tilt of the sun's spin axis to the apparent clustering in the orbits of small, icy asteroids beyond Neptune. But does Planet Nine actually exist?

Scientists puzzle over massive, never-before-seen star system in the Milky Way
Earlier this year, an international team of scientists announced the second detection of a gravitational-wave signal from the collision of two neutron stars. The event, called GW190425, is puzzling: The combined mass of the two neutron stars is greater than any other observed binary neutron star system. The combined mass is 3.4 times the mass of our sun.
